PURPOSE: The symptoms of urethral stricture are non-specific and may overlap with other common conditions that can confound diagnosis. Urologists play a key role in the initial evaluation of urethral stricture, currently provide all accepted treatments, and must be familiar with the evaluation, diagnostic tests, and surgical treatments for urethral stricture. MATERIALS AND METHODS: A systematic review of the literature using the Pubmed, Embase, and Cochrane databases (search dates January 1, 1990 to January 12, 2015) was conducted to identify peer-reviewed publications relevant to the diagnosis and treatment of urethral stricture in men. The review yielded an evidence base of 250 articles after application of inclusion/exclusion criteria. The search for the 2023 Amendment was modified to included females and males (search dates December 2015-October 2022 for males; January 1990-October 2022 for females) and a new Key Question on sexual dysfunction was added (search dates: January 1990-10/2022). After inclusion and exclusion criteria were applied, 81 studies were added to the…

PURPOSE: Transrectal prostate biopsy has come under scrutiny due to potential for postbiopsy infections and transperineal prostate biopsy is being offered as the safer alternative. However, there is a lack of randomized comparative studies. Our goal was to directly evaluate infectious and noninfectious complications following the 2 biopsy procedures. MATERIALS AND METHODS: We conducted a prospective, pragmatic, randomized clinical study in men undergoing prostate biopsy. The participants underwent either transrectal or transperineal prostate biopsy in the office under local anesthesia. The primary outcome was a 30-day composite infectious complication rate, comprising of 1 or more components including fever, genitourinary infection, antibiotic prescriptions, office or emergency visits, hospitalization, or sepsis. Secondary outcomes included 30-day composite noninfectious complications (urinary or hemorrhagic). RESULTS: = .79). No participants required hospitalization or other interventions. CONCLUSIONS: Among men undergoing transperineal or transrectal prostate biopsy, we could not…

PURPOSE: The purpose of this guideline is to provide a clinical structure with which to approach the diagnosis, counseling, and treatment of female patients with stress urinary incontinence (SUI). MATERIALS/METHODS: The primary source of evidence for the 2017 version of the SUI guideline was the systematic literature review conducted by the ECRI Institute. The initial search spanned literature from January 2005 to December 2015, with an additional updated abstract search through September 2016. The current amendment represents the first update to the 2017 iteration and includes updated literature published through February 2022. RESULTS: This guideline has been amended to reflect changes in and additions to the literature since 2017. The Panel maintained that the differentiation between index and non-index patients remained important. The index patient is a healthy female with minimal or no prolapse who desires surgical therapy for treatment of pure SUI or stress-predominant mixed urinary incontinence. Non-index patients have factors that may affect their treatment options and…

PURPOSE: The Internet is a ubiquitous source of medical information, and natural language processors are gaining popularity as alternatives to traditional search engines. However, suitability of their generated content for patients is not well understood. We aimed to evaluate the appropriateness and readability of natural language processor-generated responses to urology-related medical inquiries. MATERIALS AND METHODS: Eighteen patient questions were developed based on Google Trends and were used as inputs in ChatGPT. Three categories were assessed: oncologic, benign, and emergency. Questions in each category were either treatment or sign/symptom-related questions. Three native English-speaking Board-Certified urologists independently assessed appropriateness of ChatGPT outputs for patient counseling using accuracy, comprehensiveness, and clarity as proxies for appropriateness. Readability was assessed using the Flesch Reading Ease and Flesh-Kincaid Reading Grade Level formulas. Additional measures were created based on validated tools and assessed by 3 independent reviewers.…

PURPOSE: The purpose of this American Urological Association (AUA) guideline amendment is to provide a useful reference on the effective evidence-based treatment strategies for early-stage testicular cancer. METHODOLOGY/METHODS: The original methodology protocol included searches of PubMed®, Embase®, and the Cochrane Central Register of Controlled Trials (CENTRAL) from January 1980 through August 2018. The search strategy used medical subject heading (MeSH) terms and key words relevant to the diagnosis and treatment of early-stage testicular cancer. The searches conducted for the update presented herein utilized the same methodological protocol to capture literature published through March 2023. When sufficient evidence existed, the body of evidence was assigned a strength rating of A (high), B (moderate), or C (low) for support of Strong, Moderate, or Conditional Recommendations. In the absence of sufficient evidence, additional information is provided as Clinical Principles and Expert Opinions. RESULTS: Updates were made to statements on imaging, seminoma management, non-seminoma…

PURPOSE: We sought to compare the clinical effectiveness of the pulse-modulated Ho:YAG (holmium:yttrium-aluminum-garnet) laser and the thulium laser fiber for ureteroscopic stone management in a randomized clinical trial. The primary outcome was the ureteroscope time required to adequately fragment stones to 1 mm or less. Secondary outcomes were stone-free rate, complications, subjective surgeon measurement of laser performance, patient related stone quality of life outcomes, and measurements of laser efficiency. MATERIALS AND METHODS: An Institutional Review Board-approved randomized clinical trial was conducted to randomize patients to outpatient treatment with either the Moses 2.0 or thulium laser fiber in a 1:1 manner after stratification into groups based on the maximal diameter of treated stone (3-9.9 mm or 10-20 mm). Patient, stone, and operative parameters were compared using the appropriate categorical/continuous and parametric/nonparametric statistical tests (SPSS 25). RESULTS: = .60), or within subgroup analysis by stone size, median Hounsfield units, or stone location.…

PURPOSE: F-rhPSMA-7.3, a novel high-affinity positron emission tomography radiopharmaceutical. MATERIALS AND METHODS: Additional end points included detection rate, verified detection rate, and combined region-level positive predictive value in patients with histopathology standard of truth, and safety. RESULTS: F-rhPSMA-7.3 detection rate among all 389 patients with an evaluable scan was 83% (majority read). Among the 366 patients (median prostate-specific antigen 1.27 ng/mL) for whom a standard of truth (histopathology [n=69]/confirmatory imaging only [n=297]) was available, verified detection rate ranged from 51% (95% CI 46.1-56.6) to 54% (95% CI 48.8-59.3), exceeding the prespecified statistical threshold. Combined region-level positive predictive value ranged from 46% (95% CI 42.0-50.3) to 60% (95% CI 55.1-65.5) across the readers, not meeting the threshold. In the subset of patients with histopathology standard of truth, the verified detection rate and combined region-level positive predictive value were both above the prespecified thresholds (majority read, 81% [95% CI…

PURPOSE: We assessed the safety and efficacy of 2 injections of platelet-rich plasma for treating mild to moderate erectile dysfunction by conducting a prospective, randomized, double-blind, placebo-controlled clinical trial. MATERIALS AND METHODS: Men with mild to moderate erectile dysfunction (International Index of Erectile Function scores 11-25) were randomized to receive either 2 injections of platelet-rich plasma or placebo separated by 1 month. Primary outcome was percentage of men meeting minimum clinically important difference at 1 month after the second injection. Secondary outcomes were change in International Index of Erectile Function at 1, 3, and 6 months, and changes in penile vascular parameters and adverse events at 6 months. RESULTS: = .756). There were no major adverse events and only 1 minor adverse event in each group. There were no changes in penile Doppler parameters from baseline to 6 months. CONCLUSIONS: The results of our prospective, double-blind, randomized, placebo-controlled clinical trial suggest that 2 injections of intracavernosal platelet-rich…

PURPOSE: We report 5-year safety and efficacy outcomes of the Aquablation procedure for the treatment of men with symptomatic benign prostatic hyperplasia and large-volume prostate glands. MATERIALS AND METHODS: A total of 101 men with moderate to severe benign prostatic hyperplasia symptoms and prostate volumes between 80 and 150 mL underwent a robotic-assisted Aquablation procedure in a prospective multicenter international trial (NCT03123250). Herein we report the final 5-year results. RESULTS: < .001). A regression analysis evaluating change in PSA as a function of baseline PSA across all time points out to 5 years resulted in a 50% reduction. A prespecified subgroup analysis using a baseline prostate volume cutoff of 100 mL showed no difference in efficacy outcomes through 5 years. Freedom from a secondary benign prostatic hyperplasia procedure at 5 years was 96.3% based on Kaplan-Meier. CONCLUSIONS: At 5-years of prospective follow-up, the Aquablation procedure was shown to be safe with durable efficacy and low rates of retreatment in men with large prostates (80-150 mL).

PURPOSE: Low-grade intermediate-risk nonmuscle-invasive bladder cancer is a chronic illness commonly treated by repetitive transurethral resection of bladder tumor. We compared the efficacy and safety of intravesical chemoablation with UGN-102 (a reverse thermal gel containing mitomycin), with or without subsequent transurethral resection of bladder tumor, to transurethral resection of bladder tumor alone in patients with low-grade intermediate-risk nonmuscle-invasive bladder cancer. MATERIALS AND METHODS: This prospective, randomized, phase 3 trial recruited patients with new or recurrent low-grade intermediate-risk nonmuscle-invasive bladder cancer to receive initial treatment with either UGN-102 once weekly for 6 weeks or transurethral resection of bladder tumor. Patients were followed quarterly by endoscopy, cytology, and for-cause biopsy. The primary end point was disease-free survival. All patients were followed for adverse events. RESULTS: Trial enrollment was halted by the sponsor to pursue an alternative development strategy after 282 of a planned 632 patients were…

PURPOSE: The Optilume BPH Catheter System is a novel drug/device combination minimally invasive surgical therapy for the treatment of lower urinary tract symptoms secondary to benign prostatic hyperplasia. The PINNACLE study is a prospective, randomized, double-blind, sham-controlled clinical trial evaluating the safety and efficacy of Optilume BPH against a sham surgical procedure. MATERIALS AND METHODS: Eligible patients were men 50 years or older with symptomatic benign prostatic hyperplasia and a prostate size between 20 and 80 g. Subjects were randomized 2:1 to receive treatment with Optilume BPH or a sham surgical procedure. Blinding was maintained for subjects in both arms and evaluating personnel through 1 year postprocedure. Follow-up assessments included the International Prostate Symptom Score, uroflowmetry, and other quality-of-life and sexual function assessments. RESULTS: A total of 148 men were randomized (100 active, 48 sham) at 18 centers in the U.S. and Canada. Subjects randomized to receive Optilume BPH saw a reduction in International Prostate Symptom Score of…

PURPOSE: Incidental adrenal masses are common and require a multidisciplinary approach to evaluation and management that includes family physicians, urologists, endocrinologists, and radiologists. The purpose of this guideline is to provide an updated approach to the diagnosis, management, and follow-up of adrenal incidentalomas, with a special focus on the areas of discrepancy/controversy existing among the published guidelines from other associations. MATERIALS AND METHODS: This guideline was developed by the Canadian Urological Association (CUA) through a working group comprised of urologists, endocrinologists, and radiologists and subsequently endorsed by the American Urological Association (AUA). A systematic review utilizing the GRADE approach served as the basis for evidence-based recommendations with consensus statements provided in the absence of evidence. For each guideline statement, the strength of recommendation was reported as weak or strong, and the quality of evidence was evaluated as low, medium, or high. RESULTS: The CUA working group provided evidence- and…

PURPOSE: Urodynamics is the standard method of diagnosing bladder dysfunction, but involves catheters and retrograde bladder filling. With these artificial conditions, urodynamics cannot always reproduce patient complaints. We have developed a wireless, catheter-free intravesical pressure sensor, the UroMonitor, which enables catheter-free telemetric ambulatory bladder monitoring. The purpose of this study was twofold: to evaluate accuracy of UroMonitor pressure data, and assess safety and feasibility of use in humans. MATERIALS AND METHODS: Eleven adult female patients undergoing urodynamics for overactive bladder symptoms were enrolled. After baseline urodynamics, the UroMonitor was transurethrally inserted into the bladder and position was confirmed cystoscopically. A second urodynamics was then performed with the UroMonitor simultaneously transmitting bladder pressure. Following removal of urodynamics catheters, the UroMonitor transmitted bladder pressure during ambulation and voiding in private. Visual analogue pain scales (0-5) were used to assess patient discomfort. RESULTS:…

PURPOSE: Half of patients with muscle-invasive bladder cancer worldwide may not receive curative-intent therapy. Elderly or frail patients are most affected by this unmet need. TAR-200 is a novel, intravesical drug delivery system that provides sustained, local release of gemcitabine into the bladder over a 21-day dosing cycle. The phase 1 TAR-200-103 study evaluated the safety, tolerability, and preliminary efficacy of TAR-200 in patients with muscle-invasive bladder cancer who either refused or were unfit for curative-intent therapy. MATERIALS AND METHODS: Eligible patients had cT2-cT3bN0M0 urothelial carcinoma of the bladder. TAR-200 was inserted for 4 consecutive 21-day cycles over 84 days. The primary end points were safety and tolerability at 84 days. Secondary end points included rates of clinical complete response and partial response as determined by cystoscopy, biopsy, and imaging; duration of response; and overall survival. RESULTS: Median age of the 35 enrolled patients was 84 years, and most were male (24/35, 68.6%). Treatment-emergent adverse events related to TAR-200…

PURPOSE: We evaluated stone-free rate and complications after flexible ureteroscopy for renal stones, comparing thulium fiber laser and holmium:YAG laser with MOSES technology. MATERIALS AND METHODS: Data from adults who underwent flexible ureteroscopy in 20 centers worldwide were retrospectively reviewed (January 2018-August 2021). Patients with ureteral stones, concomitant bilateral procedures, and combined procedures were excluded. One-to-one propensity score matching for age, gender, and stone characteristics was performed. Stone-free rate was defined as absence of fragments >2 mm on imaging within 3 months after surgery. Multivariable logistic regression analysis was performed to evaluate independent predictors of being stone-free. RESULTS: < .001). At multivariable analysis, the use of thulium fiber laser and ureteral access sheath ≥8F had significantly higher odds of being stone-free. Lasing time, multiple stones, stone diameter, and use of disposable scopes showed significantly lower odds of being stone-free. CONCLUSIONS: This real-world study favors the use of thulium fiber…

PURPOSE: We explored the accuracy of a urine-based epigenetic test for detecting upper tract urothelial carcinoma. MATERIALS AND METHODS: Under an Institutional Review Board-approved protocol, urine samples were prospectively collected from primary upper tract urothelial carcinoma patients before radical nephroureterectomy, ureterectomy, or ureteroscopy between December 2019 and March 2022. Samples were analyzed with Bladder CARE, a urine-based test that measures the methylation levels of 3 cancer biomarkers (TRNA-Cys, SIM2, and NKX1-1) and 2 internal control loci using methylation-sensitive restriction enzymes coupled with quantitative polymerase chain reaction. Results were reported as the Bladder CARE Index score and quantitatively categorized as positive (>5), high risk (2.5-5), or negative (<2.5). The findings were compared with those of 1:1 sex/age-matched cancer-free healthy individuals. RESULTS: Conclusions:Bladder CARE is an accurate urine-based epigenetic test for the diagnosis of upper tract urothelial carcinoma, with much higher sensitivity than standard urine cytology.

PURPOSE: We hypothesize burnout has failed to improve and certain demographics may be disproportionately affected. MATERIALS AND METHODS: The AUA Workforce Workgroup examined work from the annual AUA Census over the past several years. Particular to this study, relevant burnout-related data were examined from the past 5 years. RESULTS: In 2021, 36.7% of urologists reported burnout compared to 36.2% in 2016. Burnout in men decreased from 36.3% to 35.2%, but increased in women from 35.3% to 49.2%. When examined by age, the largest increases in burnout were seen in those <45 years old, increasing from 37.9% to 44.8%, followed by 45-54 years old, increasing from 43.4% to 44.6%. When asked about the effect of COVID-19 on burnout, 54% of urologists didn't feel COVID-19 impacted burnout. Beyond burnout, only 25.0% of men and 4.6% of women reported no conflict between work and personal responsibilities, while 25.7% of men and 44.7% of women resolved these conflicts in favor of work or were unable to resolve them. Of respondents, 22.5% of men and 37.1% of women were "dissatisfied" with…

PURPOSE: Historically, robotic-assisted radical prostatectomy is accompanied by an inpatient hospital admission. The COVID-19 pandemic necessitated a transition to same-day discharge robotic-assisted radical prostatectomy in some centers to free up critically needed inpatient beds. This study aims to compare complications, total health care costs, and patient satisfaction for same-day discharge vs inpatient robotic-assisted radical prostatectomy. MATERIALS AND METHODS: We compared 392 consecutive robotic-assisted radical prostatectomies performed as same-day discharge (n = 206) vs inpatient (n = 186) from February 2020 to November 2022 at 2 academic medical centers. We utilized propensity score analysis to assess the impact of same-day discharge vs inpatient robotic-assisted radical prostatectomy on 30-day complications (primary outcome). Time-driven activity-based costing analysis was applied to compare total costs of robotic-assisted radical prostatectomy care, and we administered a validated Patient Satisfaction Outcome Questionnaire to compare satisfaction scores. RESULTS: =…

PURPOSE: Primary surgical treatment with retroperitoneal lymph node dissection aims to accurately stage and treat patients with node-positive pure seminoma while avoiding long-term risks of chemotherapy or radiation, traditional standard-of-care treatments. MATERIALS AND METHODS: We reported the pathologic and oncologic outcomes of patients with pure seminoma treated with primary retroperitoneal lymph node dissection in a retrospective, single-institution case series over 10 years. The primary outcome was 2-year recurrence-free survival stratified by adjuvant management strategy (surveillance vs adjuvant chemotherapy). RESULTS: Forty-five patients treated with primary retroperitoneal lymph node dissection for pure testicular seminoma metastatic to the retroperitoneum were identified. Median size of largest lymph node before surgery was 1.8 cm. Viable germ cell tumor, all of which was pure seminoma, was found in 96% (n=43) of patients. The median number of positive nodes and nodes removed was 2 and 54, respectively. Median positive pathologic node size was 2 cm (IQR 1.4-2.5 cm, range…

PURPOSE: Urologists rely heavily on videourodynamics to identify patients with neurogenic bladders who are at risk of upper tract injury, but their interpretation has high interobserver variability. Our objective was to develop deep learning models of videourodynamics studies to categorize severity of bladder dysfunction. MATERIALS AND METHODS: We performed a cross-sectional study of patients aged 2 months to 28 years with spina bifida who underwent videourodynamics at a single institution between 2019 and 2021. The outcome was degree of bladder dysfunction, defined as none/mild, moderate, and severe, defined by a panel of 5 expert reviewers. Reviewers considered factors that increase the risk of upper tract injury, such as poor compliance, elevated detrusor leak point pressure, and detrusor sphincter dyssynergia, in determining bladder dysfunction severity. We built 4 models to predict severity of bladder dysfunction: (1) a random forest clinical model using prospectively collected clinical data from videourodynamics studies, (2) a deep learning convolutional neural network of raw…

PURPOSE: Given the shortcomings of current stone burden characterization (maximum diameter or ellipsoid formulas), we sought to investigate the diagnostic accuracy and precision of a University of California, Irvine-developed artificial intelligence (AI) algorithm for determining stone volume determination. MATERIALS AND METHODS: A total of 322 noncontrast CT scans were retrospectively obtained from patients with a diagnosis of urolithiasis. The largest stone in each noncontrast CT scan was designated the "index stone." The 3D volume of the index stone using 3D Slicer technology was determined by a validated reviewer; this was considered the "ground truth" volume. The AI-calculated index stone volume was subsequently compared with ground truth volume as well with the scalene, prolate, and oblate ellipsoid formulas estimated volumes. RESULTS: There was a nearly perfect correlation between the AI-determined volume and the ground truth (R=0.98). While the AI algorithm was efficient for determining the stone volume for all sizes, its accuracy improved with larger stone size. Moreover,…

PURPOSE: Vesicourethral anastomotic stenosis after radical prostatectomy is a complication with significant adverse quality-of-life implications. Herein, we identify groups at risk for vesicourethral anastomotic stenosis and further characterize the natural history and treatment patterns. MATERIALS AND METHODS: Years 1987-2013 of a prospectively maintained radical prostatectomy registry were queried for patients with the diagnosis of vesicourethral anastomotic stenosis, defined as symptomatic and inability to pass a 17F cystoscope. Patients with follow-up less than 1 year, preoperative anterior urethral stricture, transurethral resection of prostate, prior pelvic radiotherapy, and metastatic disease were excluded. Logistic regression was performed to identify predictors of vesicourethral anastomotic stenosis. Functional outcomes were characterized. RESULTS: < .001). Of the patients treated for vesicourethral anastomotic stenosis, 82% underwent endoscopic dilation. The 1- and 5-year vesicourethral anastomotic stenosis retreatment rates were 34% and 42%, respectively. CONCLUSIONS:…

PURPOSE: Vascular-targeted photodynamic therapy with the intravascular photosensitizing agent padeliporfin (WST-11/TOOKAD-Soluble) has demonstrated therapeutic efficacy as an ablative treatment for localized cancer with potential adaptation for endoscopic management of upper tract urothelial carcinoma. This Phase I trial (NCT03617003) evaluated the safety of vascular-targeted photodynamic therapy with WST-11 in upper tract urothelial carcinoma. MATERIALS AND METHODS: Nineteen patients underwent up to 2 endoscopic vascular-targeted photodynamic therapy treatments, with follow-up for up to 6 months. Patients who had residual or recurrent upper tract urothelial carcinoma (any grade/size) failing prior endoscopic treatment or unable or unwilling to undergo surgical resection were eligible for inclusion. The primary endpoint was to identify the maximally tolerated dose of laser light fluence. A dose escalation model was employed, with increasing light fluence (100-200 mW/cm) using a modified continual reassessment method. The secondary endpoint was treatment efficacy, defined by absence…

PURPOSE: The STudy to Enhance uNderstanding of sTent-associated Symptoms sought to identify risk factors for pain and urinary symptoms, as well as how these symptoms interfere with daily activities after ureteroscopy for stone treatment. MATERIALS AND METHODS: This prospective observational cohort study enrolled patients aged ≥12 years undergoing ureteroscopy with ureteral stent for stone treatment at 4 clinical centers. Participants reported symptoms at baseline; on postoperative days 1, 3, 5; at stent removal; and day 30 post-stent removal. Outcomes of pain intensity, pain interference, urinary symptoms, and bother were captured with multiple instruments. Multivariable analyses using mixed-effects linear regression models were identified characteristics associated with increased stent-associated symptoms. RESULTS: < .001) were each associated with higher pain intensity. Neither sex, stone location, ureteral access sheath use, nor stent characteristics were drivers of stent-associated symptoms. CONCLUSIONS: In this multicenter cohort, interference persisted even as pain intensity…

PURPOSE: We evaluated 3-year oncologic outcomes following primary partial gland cryoablation. MATERIALS AND METHODS: Men with unilateral intermediate-risk prostate cancer undergoing primary partial gland cryoablation since March 2017 enrolled in a prospective outcome registry. The postablation protocol for all men included surveillance prostate biopsy at 2 years postablation and reflex prostate biopsy for cases with high suspicion of recurrence (eg, progressive rise in PSA). Recurrence of clinically significant prostate cancer was defined as any Gleason grade group ≥2 disease on postablation biopsy. Freedom from failure represented no whole gland salvage treatment, metastatic prostate cancer, or prostate cancer mortality. Freedom from recurrence and freedom from failure were characterized using nonparametric maximum likelihood estimators. RESULTS: A total of 132 men had at least 24 months of follow-up data. Biopsies identified clinically significant prostate cancer in 12 men. At 36 months, model-estimated rates of freedom from recurrence of in-field, out-of-field, and overall…

PURPOSE: Diabetes and obesity, components of the metabolic syndrome (MetS), are risk factors for urinary incontinence (UI) and chronic kidney disease (CKD). We interrogated US population-based data to explore independent, sex-specific associations between nondiabetic MetS, with and without obesity, and UI and/or CKD. MATERIALS AND METHODS: We analyzed data from 8586 males and 8420 females ≥20 years from the National Health and Nutrition Examination Survey. Multivariable logistic regression models were used to examine associations of UI or CKD with diabetes and 4 nondiabetic obesity/metabolic phenotypes: non-MetS/nonobese, MetS/nonobese, non-MetS/obese, and MetS/obese. Multinominal logistic regression models were used to assess associations of co-occurring UI/CKD with obesity/metabolic phenotypes. RESULTS: Male MetS/obese participants had increased odds of any UI (1.25; 95% CI 1.00-1.57) and urgency UI (1.36; 1.03-1.80), compared with non-MetS/nonobese participants. Female MetS/obese participants had increased odds of any UI (2.16; 95% CI 1.76-2.66), stress UI (1.51; 1.21-1.87), and…

PURPOSE: We sought to determine if the International Bladder Cancer Group IR-NMIBC (Intermediate-risk Nonmuscle-invasive Bladder Cancer) scoring system can predict the requirement of delayed transurethral resection of bladder tumor in low-grade nonmuscle-invasive bladder cancer managed by active surveillance. MATERIALS AND METHODS: We prospectively studied recurrent low-grade Ta/T1 nonmuscle-invasive bladder cancer patients managed with active surveillance with the following characteristics: low-grade papillary nonmuscle-invasive bladder cancer, ≤5 apparent low-grade nonmuscle-invasive bladder tumors, tumor diameter ≤1 cm, absence of gross hematuria, and negative urinary cytology. Subsequent transurethral resection of bladder tumor was offered to patients who no longer met the inclusion criteria or patient choice. The ability of the International Bladder Cancer Group IR-NMIBC scoring system to predict receipt of subsequent transurethral resection of bladder tumor was determined. Multivariable Cox proportional hazards analysis was used to determine factors associated with subsequent…

PURPOSE: Ureteral stone impaction is associated with unfavorable endourological outcomes; however, reliable predictors of stone impaction are limited. We aimed to assess the performance of ureteral wall thickness on noncontrast computed tomography as a predictor of ureteral stone impaction and failure rates of spontaneous stone passage, shock wave lithotripsy, and retrograde guidewire and stent passage. MATERIALS AND METHODS: This study was completed in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. A search was conducted in April 2022 for all adult, human, and English language studies investigating ureteral wall thickness using PROSPERO, OVID Medline, OVID EMBASE, Wiley Cochrane Library, Proquest Dissertations & Theses Global, and SCOPUS. A systematic review and meta-analysis using random effects model was conducted. Risk of bias was assessed using the MINORS (Methodological Index for Non-randomized Studies) score. RESULTS: Fourteen studies with a pooled population of 2,987 patients were included for quantitative…

Volume 209, Supplement 4, Page e1190: The abstract text is as given below. This erratum also includes the additional disclosure, conflict of interest, and acknowledgments that were not included in the original publication. The online and PDF versions of the article have been updated. INTRODUCTION AND OBJECTIVE: Within 10 years following definitive therapy for prostate cancer, ∼20-50% of patients (pts) experience biochemical recurrence (BCR) characterized by rising prostate-specific antigen (PSA) levels. Pts with high-risk BCR have an increased risk of mortality and improved therapies are needed. The objective of EMBARK was to evaluate the efficacy and safety of enzalutamide (enza) + androgen deprivation therapy (ADT) and enza monotherapy (mono) in pts with high-risk BCR. METHODS: EMBARK is a randomized, phase 3 study of pts with BCR considered high-risk: PSA doubling time ≤9 months and PSA ≥2 ng/mL above nadir post-radiotherapy (RT) or ≥1 ng/mL after radical prostatectomy (RP) ± postoperative RT. Pts were randomized (1:1:1) to enza 160 mg/day + leuprolide acetate (LA)…

PURPOSE: We compare Prostate Health Index, Prostate Health Index density, and PSA density in predicting clinically significant prostate cancer in MRI-guided prostate biopsy. MATERIALS AND METHODS: This is a multicenter evaluation of prospectively maintained prostate biopsy databases at 10 urology centers. Men with Prostate Health Index and MRI-guided targeted and systematic prostate biopsy performed and without prior prostate cancer diagnosis were included. The additional value of PSA density, Prostate Health Index, and Prostate Health Index density to MRI PI-RADS (Prostate Imaging Reporting & Data System) score was evaluated with multivariable analyses, area under the curve, and decision curve analyses. The proportion of unnecessary biopsies that can be avoided are estimated for clinically significant prostate cancer (International Society of Urological Pathology group ≥2 prostate cancer). RESULTS: A total of 1,215 men were analyzed. Prostate cancer and clinically significant prostate cancer were diagnosed in 51% (617/1,215) and 35% (422/1,215) of men, respectively. Clinically…

PURPOSE: Radical prostatectomy is one of the primary treatments for localized clinically significant prostate cancer. Generally, its application is based on prior biopsy. PSMA (prostate-specific membrane antigen)-PET (positron emission tomography) is considered promising in biopsy-free radical prostatectomy. The expression of PSMA in benign prostatic hyperplasia tissue and corresponding positive reaction are crucial concerns for a no-biopsy strategy. Currently, no study has explored the benign prostatic hyperplasia-related false-positive of PSMA-PET in the detection of prostate cancer. Furthermore, the influence of maximum standardized uptake value and Prostate Imaging Reporting & Data System on biopsy-free radical prostatectomy is also poorly characterized. MATERIALS AND METHODS: A retrospective study was conducted on patients who received PSMA-PET because of clinical suspicion of prostate cancer and were confirmed to have benign prostatic hyperplasia or prostate cancer. The receiver operating characteristic curve was generated for maximum standardized uptake value. Results of…

PURPOSE: Technetium-99m-sestamibi single-photon emission CT/x-ray CT is an emerging clinical tool to differentiate oncocytic tumors from renal cell carcinomas. We report data from a large institutional cohort of patients who underwent technetium-99m-sestamibi scans during evaluation of renal masses. MATERIALS AND METHODS: Patients who underwent technetium-99m-sestamibi single-photon emission CT/x-ray CT between February 2020 and December 2021 were included in the analysis. Scans were defined as "hot" for oncocytic tumor when technetium-99m-sestamibi uptake was qualitatively equivalent or higher between the mass of interest and normal renal parenchyma, suggesting oncocytoma, hybrid oncocytic/chromophobe tumor, or chromophobe renal cell carcinoma. Demographic, pathological, and management strategy data were compared between "hot" and "cold" scans. For individuals who underwent diagnostic biopsy or extirpative procedures, the concordance between radiological findings and pathology was indexed. RESULTS: A total of 71 patients (with 88 masses) underwent technetium-99m-sestamibi imaging…

PURPOSE: We evaluate utilization of treatment intensification of androgen deprivation therapy with androgen receptor pathway inhibitor/docetaxel for metastatic castration-sensitive prostate cancer patients across physician specialties. MATERIALS AND METHODS: This retrospective study identified patients with metastatic castration-sensitive prostate cancer in the Optum Research Database between 2014 and 2019. Adult men with ≥1 claim for metastatic disease within 90 days before or any time after the first prostate cancer claim who received androgen deprivation therapy were included. Physician specialty, determined from medical/pharmacy claims during each line of therapy, was categorized as urologist only, oncologist only, both (urologists and oncologists), or other (other specialties). Treatment intensification and patient characteristics were analyzed descriptively. RESULTS: Of 4,675 patients, 16% were treated by urologists only, 20% by oncologists only, 63% by both, and 1.1% by others. The most frequent first line of therapy was androgen deprivation therapy ± first-generation…

PURPOSE: Variant histology or divergent differentiation (VH/DD) of urothelial carcinoma (UC) may impact outcomes after neoadjuvant chemotherapy (NAC) in muscle-invasive bladder cancer. Our aim was to assess the pathological response and progression-free survival (PFS) of patients with VH/DD in the prospective VESPER clinical trial. MATERIALS AND METHODS: This post hoc study included 300 NAC-treated patients with available transurethral diagnostic slides. Presence and percentage of VH/DDs were reviewed. For pathological response, logistic regression models were computed to measure association with VH/DD. For PFS, the associations were estimated in Cox proportional hazard regression model. All models were adjusted for randomization arm. RESULTS: VH/DD was identified in 177/300 patients (59%) and was predominant (≥50%) in 85/177. Compared to pure UC, VH/DD (≥10% or ≥50%) was not associated with a difference in proportion of complete pathological response (ypT0N0; OR adjusted: 0.79, 95% CI 0.49-1.29), downstaging (≤ypT1N0; OR adjusted: 0.62, 95% CI 0.37-1.02), or with an increased…

PURPOSE: Assessments of financial toxicity among patients with metastatic prostate cancer are lacking. Using patient surveys, we sought to identify coping mechanisms and assess characteristics associated with lower financial toxicity. MATERIALS AND METHODS: Surveys were administered to all patients seen at a single center's Advanced Prostate Cancer Clinic over a 3-month period. Surveys included the COST-FACIT (COmprehensive Score for Financial Toxicity) and coping mechanism questionnaires. Patients with metastatic disease (lymph nodes, bone, visceral) were included for analysis. Coping mechanisms were compared between patients experiencing low (COST-FACIT >24) vs high (COST-FACIT ≤24) financial toxicity using Fisher's exact test. Multivariable linear regression was used to evaluate characteristics associated with lower financial toxicity. RESULTS: < .001) to pay for their treatment. CONCLUSIONS: In this cross-sectional study, patients with metastatic prostate cancer and high financial toxicity were more likely to decrease spending on basic goods and leisure activities and use…

PURPOSE: We studied whether adding percent free PSA to total PSA improves prediction of clinically significant prostate cancer and fatal prostate cancer. MATERIALS AND METHODS: A total of 6,727 men within the intervention arm of PLCO (Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial) had baseline percent free PSA. Of this cohort, 475 had clinically significant prostate cancer and 98 had fatal prostate cancer. Cumulative incidence and Cox analyses were conducted to evaluate the association between percent free PSA/PSA and clinically significant prostate cancer/fatal prostate cancer. Harrell's C index evaluated predictive ability. Kaplan-Meier analysis assessed survival. RESULTS: < .001) per 1% decrease. Percent free PSA improved prediction of clinically significant prostate cancer and fatal prostate cancer for all race groups. CONCLUSIONS: In a large U.S. screening trial, the addition of percent free PSA to total PSA in men with baseline PSA ≥2 ng/mL improved prediction of clinically significant prostate cancer and fatal prostate cancer. Free PSA should be used to…

PURPOSE: We evaluate the outcomes of ureteroscopy vs prone mini-percutaneous nephrolithotomy for 1-2-cm renal stones using a 2-group parallel randomized control trial. MATERIALS AND METHODS: Adult patients presenting with renal stones between 1 and 2 cm were randomized. Exclusion criteria included solitary kidney, multiple stones, and comorbidities precluding prone positioning. Block randomization was performed and was opened to the surgeon the morning of the procedure. Stone-free rate was evaluated by computed tomography 1-30 days postoperatively. Complications, re-treatment rates, and costs were evaluated. RESULTS: = .2541). CONCLUSIONS: In a prospective, randomized, controlled clinical trial using a 2-mm residual stone burden cutoff, mini-percutaneous nephrolithotomy was more likely to render patients stone-free than flexible ureteroscopy. Complications, surgical times, and operating margins did not vary between the approaches.

PURPOSE: Interstitial cystitis/bladder pain syndrome is a chronic urological condition diagnosed in nearly 8 million females in the United States. Whether urinary microbiota play an etiological role remains controversial. Most studies assessed the microbiota of interstitial cystitis/bladder pain syndrome patients with voided or catheterized urine as a proxy for bladder urothelium; however, urine may not be a true reflection of the bladder microbiota. Bladder biopsy tissue may provide a more accurate, and thus more clinically relevant, picture of bladder microbiota. MATERIALS AND METHODS: Bladder biopsy tissues were obtained from: (1) 30 females with interstitial cystitis/bladder pain syndrome (18-80 years old) via cystoscopically guided cold-cup biopsy following therapeutic bladder hydrodistention, and (2) 10 non-interstitial cystitis/bladder pain syndrome females undergoing pelvic organ prolapse repair. To detect bacteria, technical duplicates of each RNAlater-preserved biopsy were subjected to 16S rRNA gene sequencing. To visualize bacteria, paraformaldehyde-fixed,…

PURPOSE: for Peyronie's disease, there has been significant debate regarding its role and comparable efficacy to surgery. MATERIALS AND METHODS: + RestoreX penile traction therapy + sildenafil or penile surgery + RestoreX penile traction therapy + sildenafil, with 3-month data presented. Primary objectives were overall satisfaction, subjective changes in erectile function, penile sensation, penile length, and changes in the International Index of Erectile Function-Erectile Function Domain score. Secondary outcomes included objective changes in length, curve, adverse events, and other standardized and nonstandardized questionnaires. RESULTS: < .01). CONCLUSIONS: + RestoreX penile traction therapy + sildenafil results in lesser curve improvements but greater penile length and fewer adverse events, including impacts on subjective erectile function and sensation, than men treated with surgery.

PURPOSE: We sought to determine which treatment between flexible ureteroscopy and shock wave lithotripsy has a better stone-free rate in pediatric patients (<18 years) with renal or proximal ureteric stones (<2 cm). Subanalysis for all outcomes for randomized controlled trials only. MATERIALS AND METHODS: Using PubMed, Web of Science, and the Cochrane database, we identified studies (randomized clinical trials and prospective comparative nonrandomized studies) published until August 2022 reporting surgical outcomes of pediatrics patients undergoing flexible ureteroscopy and shock wave lithotripsy with renal or proximal ureteric stones <2 cm (PROSPERO ID: CRD42022378790). Only randomized controlled trials were considered for meta-analysis. Stone-free rate, operative time, and complications were analyzed. Analysis was performed in R. RESULTS: = 0.95). CONCLUSIONS: Flexible ureteroscopy has a significantly higher stone-free rate than shock wave lithotripsy, with no difference in complication rate or fluoroscopy exposure time, and significantly higher operative times and hospital stay.…

PURPOSE: We aimed to assess the feasibility of unilateral extended pelvic lymph node dissection in the era of modern prostate cancer imaging. MATERIALS AND METHODS: We analyzed a multi-institutional data set of men with cN0 disease diagnosed by magnetic resonance imaging-targeted biopsy who underwent prostatectomy and bilateral extended pelvic lymph node dissection. The outcome of the study was lymph node invasion contralateral to the prostatic lobe with worse disease features, ie, dominant lobe. Logistic regression to predict lymph node invasion contralateral to the dominant lobe was generated and internally validated. RESULTS: Overall, data from 2,253 patients were considered. Lymph node invasion was documented in 302 (13%) patients; 83 (4%) patients had lymph node invasion contralateral to the dominant prostatic lobe. A model including prostate-specific antigen, maximum diameter of the index lesion, seminal vesicle invasion on magnetic resonance imaging, International Society of Urological Pathology grade in the nondominant side, and percentage of positive cores in the…

PURPOSE: OnabotulinumtoxinA is an approved treatment for neurogenic detrusor overactivity in adults inadequately managed with anticholinergics, and more recently was approved in children on the basis of a phase 3, 48-week, single-treatment study (NCT01852045). Given the paucity of long-term pediatric data, we report on the continued safety in these patients after repeated onabotulinumtoxinA treatment. MATERIALS AND METHODS: This was a multicenter, double-blind, repeat-treatment extension study (NCT01852058) in patients who entered from the preceding single-treatment study. Data were integrated across both studies. All patients (5-17 years) used clean intermittent catheterization and could receive dose escalations based on response to preceding treatment (50 U, 100 U, or 200 U onabotulinumtoxinA [not to exceed 6 U/kg]). RESULTS: Overall, 95, 90, 55, and 11 patients received 1, 2, 3, and 4 treatments with onabotulinumtoxinA, respectively, and median (quartiles) duration of follow-up was 82 (65, 94) weeks. The safety profile was similar across doses and after repeat treatments. The…

PURPOSE: Testosterone administration prior to hypospadias repair is common practice among pediatric urologists; however, its impact on surgical outcomes remains controversial. We hypothesize that testosterone administration prior to distal hypospadias repair with urethroplasty significantly decreases postoperative complications. MATERIALS AND METHODS: We queried our hypospadias database for primary distal hypospadias repairs with urethroplasty from 2015 to 2021. Patients undergoing repair without urethroplasty were excluded. We collected information on patient age, procedure type, testosterone administration status, initial visit and intraoperative glans width, urethroplasty length, and postoperative complications. To determine the role of testosterone administration on incidence of complications, a logistic regression adjusting for initial visit glans width, urethroplasty length, and age was performed. RESULTS: = .039). CONCLUSIONS: This retrospective review of patients shows that on multivariable analysis there is significant association between testosterone administration and…

PURPOSE: Post-ureteroscopy stent placement carries significant morbidity which can interfere with daily life. This discomfort unfortunately leads to high utilization of opioid pain medications, which have a known risk of addiction. Cannabidiol oil represents an alternative analgesic that has proven anti-inflammatory and antinociceptive effects. The purpose was to evaluate the effect of a Food and Drug Administration-approved cannabidiol oil (Epidiolex) on pain control and opioid usage in the post-ureteroscopy setting. MATERIALS AND METHODS: This was a prospective, randomized, double-blind, placebo-controlled trial at a tertiary care center. Ninety patients undergoing ureteroscopy with stent placement for urinary stone disease were randomized 1:1 to placebo or 20 mg cannabidiol oil daily for 3 days postoperatively. Both groups were prescribed a rescue narcotic, tamsulosin, oxybutynin, and phenazopyridine. Daily pain scores, medication usage, and ureteral stent symptoms using the validated Ureteral Stent Symptom Questionnaire were recorded postoperatively. RESULTS: Both the placebo…

PURPOSE: Stimulated Raman histology is an innovative technology that generates real-time, high-resolution microscopic images of unprocessed tissue, significantly reducing prostate biopsy interpretation time. This study aims to evaluate the ability for an artificial intelligence convolutional neural network to interpretate prostate biopsy histologic images created with stimulated Raman histology. MATERIALS AND METHODS: Unprocessed, unlabeled prostate biopsies were prospectively imaged using a stimulated Raman histology microscope. Following stimulated Raman histology creation, the cores underwent standard pathological processing and interpretation by at least 2 genitourinary pathologists to establish a ground truth assessment. A network, trained on 303 prostate biopsies from 100 participants, was used to measure the accuracy, sensitivity, and specificity of detecting prostate cancer on stimulated Raman histology relative to conventional pathology. The performance of the artificial intelligence was evaluated on an independent 113-biopsy test set. RESULTS: Prostate biopsy images…

PURPOSE: Human urinary bladder transplantation has never been performed. From a technical standpoint, challenges include the complex deep pelvic vascular anatomy, limited intraoperative visualization, and high procedural complexity. In preparation for a first-in-human clinical trial, we report preclinical studies to develop the technique of robotic retrieval and autotransplantation of vascularized composite bladder allograft. MATERIALS AND METHODS: Institutional Animal Care and Use Committee, Institutional Review Board, and UNOS (United Network for Organ Sharing) approvals were obtained, and IDEAL (Idea, Development, Exploration, Assessment, Long-term Study) Reporting Guidelines were followed. Robotic vascularized composite bladder allograft recovery, back-table graft preparation, and robotic autotransplantation were performed in 3 vascularized model settings: living porcine (n=3), pulsatile human cadavers (n=2), and heart-beating brain-dead deceased research human donors (n=5). Our primary objective was to develop a reproducible technique for robotic vascularized composite bladder…

PURPOSE: We sought to determine microbe-metabolite composition and interactions within indwelling ureteral stent biofilms, determine their association with patient factors including infection, and reconstitute biofilm formation on relevant surface materials in vitro. MATERIALS AND METHODS: -tests or PERMANOVA. Biofilm deposition by microbial strain and device material type were analyzed using plate counts and scanning electron microscopy following bioreactor incubation. RESULTS: most) and material type (titanium least). CONCLUSIONS: Ureteral stent biofilms exhibit patterns unique to stent-associated infection and antibiotic exposure during indwelling time. Microbes isolated from stents reconstituted biofilm formation in vitro. This work provides a platform to test novel materials, evaluate new coatings for anti-biofilm properties, and explore commensal strain use for bacterial interference against pathogens.

PURPOSE: We evaluated oncologic risks in a large cohort of patients with radiographic cystic renal masses who underwent active surveillance or intervention. MATERIALS AND METHODS: A single-institutional database of 4,340 kidney lesions managed with either active surveillance or intervention between 2000-2020 was queried for radiographically cystic renal masses. Association of radiographic tumor characteristics and high-grade pathology was evaluated. RESULTS: > .9). CONCLUSIONS: A disconnect between "cystic" designation on imaging and pathology exists for renal lesions. Over 80% of radiographic Bosniak cystic lesions are not described as "cystic" on pathology reports. More than 1 in 5 resected cystic renal lesions demonstrated high-grade disease. Despite this finding, judiciously managed active surveillance ± delayed intervention is a safe and effective management option for most radiographic cystic renal masses.

PURPOSE: We sought to examine sperm retrieval and testicular histology in males of different ages with Klinefelter syndrome. MATERIALS AND METHODS: We identified all males with Klinefelter syndrome who underwent microdissection testicular sperm extraction at our institution from 1995 to 2020. Patients were divided into adolescent (<20 years) and adult (≥20 years) cohorts. Histology and sperm retrieval were compared using chi-square statistics. Multivariable logistic regression models were used to examine factors associated with successful sperm retrieval. RESULTS: = .03) was associated with higher odds of successful sperm retrieval. CONCLUSIONS: Younger males more frequently had germ cell-containing testis histology, however this finding was not associated with a higher odds of sperm retrieval. Reproductive urologists should counsel azoospermic males with Klinefelter syndrome that sperm retrieval during adolescence for fertility preservation is not required and can be performed in young adulthood.

PURPOSE: Ureteral stents are commonly used for the treatment of ureteral obstruction, most often urolithiasis. Their use may be associated with significant bothersome symptoms and discomfort. Prior studies have examined the effects of various medication regimens on ureteral stent symptoms. This study utilized Bayesian network meta-analysis to analyze all available evidence on the pharmacological management of ureteral stent-related symptoms. MATERIALS AND METHODS: In December 2022 a systematic review was conducted following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines on randomized prospective studies on pharmacological management of ureteral stent-related symptoms reporting outcomes using the Ureteral Stent Symptom Questionnaire score on urinary symptoms and pain. The data were analyzed in Review Manager 5.3 and R Studio where a Bayesian network meta-analysis was performed. Treatments were ranked using surface under the cumulative ranking curve and mean difference vs placebo with 95% credible intervals. RESULTS: A total of 26 studies were…

PURPOSE: This post hoc analysis of PROSPER evaluated the relationship between depth of PSA decline and clinical outcomes in enzalutamide-treated men with nonmetastatic castration-resistant prostate cancer. MATERIALS AND METHODS: values were based on an unstratified Cox proportional analysis model. RESULTS: In enzalutamide-treated men, PSA declines of <50%, ≥50% to <90%, ≥90% with nadir ≥0.2 ng/mL, and ≥90% with nadir <0.2 ng/mL were associated with median metastasis-free survival in months (95% confidence intervals) of 22.1 (14.8-not reached), 34.2 (29.4-not reached), 36.6 (33.4-not reached), and not reached, respectively, and overall survival in months (95% confidence intervals) of 40.8 (31.7-44.9), 54.4 (49.0-67.0), 64.3 (63.4-not reached), and not reached, respectively. CONCLUSIONS: There was a statistically significant correlation between greater depth of PSA decline and improved clinical outcomes, suggesting a previously underappreciated relationship between changes in PSA levels and clinical outcomes in nonmetastatic castration-resistant prostate cancer.

PURPOSE: There are limited data on ablation effects of thulium fiber laser (TFL) settings with varying stone composition. Similarly, little is known surrounding the photothermal effects of TFL lithotripsy regarding the chemical and structural changes after visible char formation. We aim to understand the TFL's ablative efficiency across various stone types and laser settings, while simultaneously investigating the photothermal effects of TFL lithotripsy. MATERIALS AND METHODS: Human specimens of calcium oxalate monohydrate, calcium oxalate dihydrate, uric acid, struvite, cystine, carbonate apatite, and brushite stones were ablated using 13 prespecified settings with the Coloplast TFL Drive. Pre- and postablation mass, ablation time, and total energy were recorded. Qualitative ablative observations were recorded at 1-minute intervals with photographs and gross description. Samples were analyzed with Fourier-transform infrared spectroscopy pre- and postablation and electron microscopy postablation to assess the photothermal effects of TFL. RESULTS: Across all settings and stone types,…

PURPOSE: Transcutaneous spinal cord stimulation (TSCS) is a novel neuromodulation modality developed to promote functional restoration in patients with neurological injury or disease. Previous pilot data suggest that lower urinary tract dysfunction (LUTD) due to stroke may be partially alleviated by TSCS. In this study, we examine the mechanism of this effect by evaluating bladder-related brain activity in patients before and after TSCS therapy and comparing it to healthy volunteers. MATERIALS AND METHODS: Patients who developed storage LUTD after a stroke and healthy volunteers without LUTD were recruited. Patients and healthy volunteers underwent simultaneous urodynamics and functional MRI. Patients then completed 24 biweekly sessions of TSCS and underwent another simultaneous urodynamics-functional MRI study. Clinical outcomes were assessed using validated questionnaires and voiding diary. RESULTS: Fifteen patients and 16 healthy volunteers completed the study. Following TSCS, patients exhibited increased blood-oxygen-level-dependent activity in areas including periaqueductal…

PURPOSE: We describe a novel application of the reverse thermal polymer gel of mitomycin C (UGN-101) as adjuvant therapy after complete endoscopic ablation of upper tract urothelial carcinoma. MATERIALS AND METHODS: We retrospectively reviewed patients treated with UGN-101 from 15 high-volume centers. Adjuvant therapy was defined as treatment administered following visually complete endoscopic ablation. Response at primary endoscopic evaluation was defined as no visual tumor or negative biopsy. Ipsilateral disease-free and progression-free survival were estimated by the Kaplan-Meier method. Ureteral stenosis and other adverse events were abstracted from the medical records. Ureteral stenosis was defined as a condition requiring ureteral stent or nephrostomy, or that would typically warrant stent or nephrostomy. RESULTS: = .28). CONCLUSIONS: In patients being considered for UGN-101, maximal endoscopic ablation prior to UGN-101 treatment may result in fewer patients with disease at first endoscopy and possibly fewer adverse events than primary chemoablative therapy. Longer follow-up…

PURPOSE: Elevated hematocrit (Hct) can result in increased risk of major adverse cardiovascular events (MACE) in men receiving testosterone therapy (TTh). However, the impact of the magnitude of the change in Hct from baseline after starting TTh has never been assessed. MATERIALS AND METHODS: To assess whether an increase in Hct after initiating TTh is associated with an increased risk of MACE within 3 and 24 months of initiating TTh, we queried the TriNetX Research network database for men over the age of 18 with Hct values obtained within 6 months before starting TTh, and who had follow-up Hct measurements within 3 and 24 months after beginning TTh from 2010 to 2021. Men with and without a subsequent increase in Hct after initiating TTh were propensity matched. MACE was defined as myocardial infarction, stroke, or death. RESULTS: After matching, 10,511 men who experienced an any increase in Hct after initiating TTh and an equal number of controls who did have an increase in Hct were included. Compared to controls who did not have an increase in Hct after starting TTh, the men who…

PURPOSE: Ureteroscopy is a commonly performed procedure, with postoperative pain that can lead to revisits and opioid prescribing. Perioperative gabapentinoids have shown promise in decreasing pain and opioid use. We hypothesized that single-dose perioperative pregabalin would be safe and efficacious for decreasing pain after ureteroscopy. MATERIALS AND METHODS: This was an Institutional Review Board-approved and registered blinded, placebo-controlled trial conducted at a single institution. Patients undergoing ureteroscopy without histories that would limit use of opioids, gabapentinoids, and nonsteroidal medications were enrolled. Either 300 mg pregabalin or placebo was administered 1 hour before ureteroscopy. Pain was assessed using a visual analogue scale before administration and 1 hour after surgery. Clinical factors, pain scores, a proxy for cognition, patient satisfaction, and opioid prescribing were assessed in the first 30 postoperative days. RESULTS: = .004), a finding that remained statistically significant when accounting for patient age and preoperative pain scores.…

PURPOSE: While active surveillance is the preferred management for most men with low-risk prostate cancer, a subset may harbor more aggressive disease. In this review we examine the evidence underlying an accurate and nuanced assessment of oncologic risk in these men. MATERIALS AND METHODS: We performed a nonsystematic literature review current to January 2023 on PubMed for articles relating to clinical, pathological, molecular, and imaging-based modalities available for risk assessment in men with low-risk prostate cancer. Relevant articles were reviewed by the authors and evidence was summarized. RESULTS: Many tools are available to personalize clinical decision-making for men with low-risk prostate cancer. Total volume of cancer, PSA density, and presence of ductal components have been consistently and strongly associated with current or future evidence of higher-grade disease. PSA kinetics, Prostate Imaging Reporting & Data System 4/5 lesions on MRI, perineural invasion, germline mutations, and genomic classifiers all appear to be associated with an increased risk, although are…

PURPOSE: To prevent avoidable treatment and make more informed care decisions about small renal masses, the use of renal mass biopsies has increased since the early 2000s. In April 2017, Atrium Health Carolinas Medical Center began requiring biopsies before all percutaneous thermal ablation procedures for renal masses. We aim to determine the effect of this preablation biopsy mandate on small renal mass treatment decisions. MATERIALS AND METHODS: Our study is a retrospective analysis of a prospectively managed database designed to track patients with small renal masses presented at the Kidney Tumor Program from 2000-2020. We separated patients into 2 cohorts (pre- and postmandate) based on the initial encounter date, excluding those from April 2017-April 2018 to allow for implementation of the mandate. We also excluded patients with masses >4 cm. RESULTS: = .03). CONCLUSIONS: Our data indicate that a preablation renal mass biopsy mandate is associated with the wider use of biopsies for all small renal mass patients, fewer surgical interventions, and an increase in active…

PURPOSE: Symptom heterogeneity in interstitial cystitis/bladder pain syndrome and chronic prostatitis/chronic pelvic pain syndrome, collectively termed urological chronic pelvic pain syndrome, has resulted in difficulty in defining appropriate clinical trial endpoints. We determine clinically important differences for 2 primary symptom measures, pelvic pain severity and urinary symptom severity, and evaluate subgroup differences. MATERIALS AND METHODS: The Multidisciplinary Approach to the Study of Chronic Pelvic Pain Symptom Patterns Study enrolled individuals with urological chronic pelvic pain syndrome. We defined clinically important differences by associating changes in pelvic pain severity and urinary symptom severity over 3 to 6 months with marked improvement on a global response assessment using regression and receiver operating characteristic curves. We evaluated clinically important differences for absolute and percent change and examined differences in clinically important differences by sex-diagnosis, presence of Hunner lesions, pain type, pain widespreadness, and…

PURPOSE: The aim of this meta-analysis was to investigate the effect of pharmacotherapy for overactive bladder on the pathogenesis of urinary tract infection. MATERIALS AND METHODS: A comprehensive search was performed in MEDLINE and the Cochrane Library using terms for overactive bladder, antimuscarinic agents, and beta 3-adrenoceptor agonists. The primary end point was the emergence of urinary tract infection after pharmacotherapy for overactive bladder. The secondary end point was the emergence of urinary retention, dysuria, and/or increased residual urine volume after overactive bladder treatment. Meta-analyses were conducted using random-effects models. RESULTS: = .708). CONCLUSIONS: This meta-analysis showed that antimuscarinic agents statistically significantly increased the incidences of urinary tract infection and lower urinary tract symptoms and dysfunction, but beta 3-adrenoceptor agonists did not. To prevent urinary tract infection emergence, beta 3-adrenoceptor agonists might be safer than antimuscarinic agents.

PURPOSE: The treated natural history of nonmetastatic plasmacytoid variant of bladder cancer (PV-BCa) is poorly understood owing to its rarity. We sought to examine the disease recurrence and metastasis patterns in this select group of patients in order to identify opportunities for intervention. MATERIALS AND METHODS: We conducted a natural language processing algorithm-augmented retrospective chart review of 56 consecutive patients who were treated with curative intent for nonmetastatic PV-BCa at our institution between 1998 and 2018. Kaplan-Meier and multivariable Cox regression methods were used for survival analyses. RESULTS: = .001). CONCLUSIONS: PV-BCa is a disease with high lethality. Despite multimodal treatment, a vast majority of patients develop atypical intraperitoneal metastasis soon after therapy and rapidly succumb to it. Clinical trials evaluating utility of hyperthermic intraperitoneal chemotherapy and/or immunotherapy may be warranted in this high-risk population.

PURPOSE: Luteinizing hormone-releasing hormone (LHRH) agonists are believed to have higher cardiovascular risk relative to gonadotropin-releasing hormone (GnRH) antagonists. However, previous studies have not consistently demonstrated this. We used real-world clinical practice data to evaluate differences in major adverse cardiovascular events (MACE) risk between LHRH agonists compared to a GnRH antagonist following androgen deprivation therapy (ADT) initiation. MATERIALS AND METHODS: We performed a retrospective analysis of data in the Decision Resources Group (now Clarivate) Real World Evidence repository, which represents >300 million US patients from 1991 to 2020 across all US regions. Patients with prostate cancer who received at least 1 injection of ADT were included. The risks of MACE and all-cause mortality as independent endpoints were evaluated, Kaplan-Meier curves were constructed, and associations between MACE and all available confounding risk factors were evaluated by Cox regression analysis using Statistical Package for the Social Sciences. RESULTS: < .001).…

PURPOSE: Bladder and bowel dysfunction is a common but underdiagnosed pediatric entity which may represent up to 47% of pediatric urology consults. The objectives of this observational study were to determine functional 1-year outcomes following standard treatment of bladder and bowel dysfunction in both control and neuropsychiatric developmental disorder groups using validated questionnaires, and to perform an initial cost analysis. MATERIALS AND METHODS: This was a prospective observational study conducted across a number of academic European centers (July 2020-November 2022) for new bladder and bowel dysfunction patients. Parents completed a sociodemographic survey, information pertaining to prior neuropsychiatric developmental disorder diagnoses, as well as a number of validated functional scores. RESULTS: A total of 240 patients were recruited. In the control bladder and bowel dysfunction group, the baseline Dysfunctional Voiding Scoring System and Childhood Bladder and Bowel Dysfunction Questionnaire scores were 20% and 17.% lower, respectively, after 1 year compared to the…

PURPOSE: We sought to characterize sex-stratified differences in bladder management and bladder symptoms and satisfaction after spinal cord injury. MATERIALS AND METHODS: This study was a prospective, cross-sectional, observational study; eligibility included: age ≥18 years and acquired spinal cord injury. Bladder management was grouped as (1) clean intermittent catheterization, (2) indwelling catheter, (3) surgery, and (4) voiding. Primary outcome was Neurogenic Bladder Symptom Score. Secondary outcomes were subdomains of the Neurogenic Bladder Symptom Score and bladder-related satisfaction. Multivariable regression was used in sex-stratified models to establish associations between participant characteristics and outcomes. RESULTS: A total of 1,479 participants enrolled in the study. Of the patients 843 (57%) were paraplegic and 585 (40%) were women. Median age and time from injury were 44.9 (IQR 34.3, 54.1) and 11 (IQR 5.1, 22.4) years. Women utilized clean intermittent catheterization at a lower rate (42.6% vs 56.5%) and surgery at a higher rate (22.6% vs 7.0%), especially…

PURPOSE: Our goal was to compare outcomes of early vs delayed transurethral surgery for benign prostatic hyperplasia after an episode of acute urinary retention compared to men without preoperative acute retention. MATERIALS AND METHODS: We conducted a retrospective cohort analysis using data from the New York Statewide Planning and Research Cooperative System from 2002-2016. We identified men ≥40 years old who underwent primary ambulatory transurethral resection or photoselective vaporization of the prostate, assessing surgical failure as time to reoperation or recatheterization. We categorized presurgical acute urinary retention by number of episodes: none (reference), 1, or ≥2 precatheterizations, and time from first retention episode to surgery: none (reference), 0-6 months, and >6 months. We used Fine-Gray competing-risk models to predict surgical failure at 10 years, with presurgical acute retention as the primary predictor, adjusted for age, race, insurance, Charlson Comorbidity Index score, preoperative urinary infection, and procedure type, with death as the competing risk.…

PURPOSE: Men on active surveillance with Grade Group 1 prostate cancer who reclassify to Grade Group 2 on surveillance biopsy often leave active surveillance. We aimed to identify subgroups of men who can safely remain on active surveillance despite preoperative reclassification to Grade Group 2. MATERIALS AND METHODS: We studied 249 active surveillance patients with surveillance biopsies classified as Grade Group 1 or Grade Group 2 who underwent radical prostatectomy. Perineural invasion, cancer volume, linear length and maximum percentage of Gleason pattern 4, and prostate-specific antigen density were evaluated. Radical prostatectomy adverse pathology was defined by any of: pN1; ≥pT3; ≥Grade Group 2 with ≥20% Gleason pattern 4; intraductal carcinoma; large cribriform glands. RESULTS: A multivariable logistic regression model incorporating prostate-specific antigen density and perineural invasion stratified radical prostatectomy adverse pathology risk among Grade Group 1 and Grade Group 2 active surveillance patients. 57% (39/68) of Grade Group 1 men reclassified to Grade Group 2…

PURPOSE: Lower pole renal stones are associated with the lowest stone-free status of any location in the urinary tract during retrograde intrarenal surgery. Prior work has suggested displacing lower pole stones to a more accessible part of the kidney to improve stone-free status. We sought to prospectively compare the efficacy of laser lithotripsy in situ vs after displacement during retrograde intrarenal surgery for lower pole stones. MATERIALS AND METHODS: Between July 2017 and May 2022 patients undergoing retrograde intrarenal surgery for lower pole stones were randomized into an in situ or displacement group. Demographics, comorbidities, and operative parameters were documented. Primary outcome was stone-free status, determined by combination of abdominal x-ray and renal ultrasound at 30-day follow-up. Secondary outcomes included operative time, 30-day complications, emergency department visits, and readmissions. RESULTS: = .024). CONCLUSIONS: Basket displacement of lower pole stones results in a significantly higher stone-free status compared to in situ lithotripsy. The…

PURPOSE: We compare health-related quality of life using a broad range of validated measures in patients randomized to robotic-assisted radical cystectomy vs open radical cystectomy. METHODS: We retrospectively analyzed patients that had enrolled in both a randomized controlled trial comparing robotic-assisted laparoscopic radical cystectomy vs open radical cystectomy and a separate prospective study of health-related quality of life. The prospective health-related quality of life study collected 14 patient-reported outcomes measures preoperatively and at 3, 6, 12, 18, and 24 months postoperatively. Linear mixed-effects models with an interaction term (study arm×time) were used to test for differences in mean domain scores and differing effects of approach over time, adjusting for baseline scores. RESULTS: < .001) due to lower open radical cystectomy scores at 3 and 24 months. Other domains evaluating urinary, bowel, sexual, and psychosocial health-related quality of life were similar. CONCLUSIONS: Over a broad range of health-related quality of life domains comparing…

PURPOSE: There is a paucity of reported long-term outcomes after contemporary urethroplasty. Our objective is to determine the long-term success of modern urethroplasty and identify factors associated with stricture recurrence in this context. MATERIALS AND METHODS: Patients undergoing urethroplasty from July 2003 to May 2013 with at least 100 months of follow-up were identified. Long-term outcomes including stricture recurrence and patient satisfaction were evaluated by review of regional/provincial electronic records and telephone interview. Urethroplasty failure was defined as a recurrent stricture (<16F) confirmed on cystoscopy. Cox regression was used to evaluate variables associated with long-term stricture recurrence. RESULTS: < .001), in particular lichen sclerosus (HR 4.46, 95% CI 2.25-9.53), radiation (HR 4.25, 95% CI 1.65-10.9), and infectious strictures (HR 5.27, 95% CI 2.03-13.7), were independently associated with stricture recurrence. CONCLUSIONS: This study affirms the widely held belief that modern urethroplasty provides high long-term patency and patient-reported…

PURPOSE: We sought to determine whether clinical risk factors and morphometric features on preoperative imaging can be utilized to identify those patients with cT1 tumors who are at higher risk of upstaging (pT3a). MATERIALS AND METHODS: We performed a retrospective international case-control study of consecutive patients treated surgically with radical or partial nephrectomy for nonmetastatic renal cell carcinoma (cT1 N0) conducted between January 2010 and December 2018. Multivariable logistic regression models were used to study associations of preoperative risk factors on pT3a pathological upstaging among all patients, as well as subsets with those with preoperative tumors ≤4 cm, renal nephrometry scores, tumors ≤4 cm with nephrometry scores, and clear cell histology. We also examined association with pT3a subsets (renal vein, sinus fat, perinephric fat). RESULTS: Among the 4,092 partial nephrectomy and 2,056 radical nephrectomy patients, pathological upstaging occurred in 4.9% and 23.3%, respectively. Among each group independent factors associated with pT3a upstaging were…

PURPOSE: We assessed the prognostic significance of quantification of perineural invasion on prostate biopsy. MATERIALS AND METHODS: We quantified actual perineural invasion foci in the entire prostate biopsy specimens from 724 patients and compared corresponding radical prostatectomy findings and long-term oncologic outcomes. RESULTS: < .001) showed significance for recurrence. Meanwhile, compared with CAPRA (Cancer of the Prostate Risk Assessment) score alone (0.687/0.685), Harrell's C index/AUC for predicting 5-year recurrence-free survival was gradually increased when 1 (0.722/0.740), 2 (0.747/0.773), or 3 (0.760/0.792) point(s) were additionally assigned to multifocal perineural invasion. CONCLUSIONS: Multifocal perineural invasion and >1 perineural invasion per 10-mm tumor on each prostate biopsy were thus found to be associated with poorer prognosis, as independent predictors, in men with prostate cancer undergoing radical prostatectomy.

PURPOSE: Most studies on interstitial cystitis/bladder pain syndrome and chronic prostatitis/chronic pelvic pain syndrome use typical or average levels of pelvic pain or urological symptom intensity as their outcome, as both are associated with reduced quality of life. Symptom exacerbations or "flares" have also been found to be associated with reduced quality of life, but no studies, to our knowledge, have investigated whether these associations are independent of typical pelvic pain levels and thus might be useful additional outcome measures (or stated differently, whether reducing flare frequency even without reducing mean pain intensity may be important to patients). MATERIALS AND METHODS: We used screening visit and weekly run-in period data from the Multidisciplinary Approach to the Study of Chronic Pelvic Pain Symptom Patterns Study to investigate associations between flare frequency and multiple measures of illness impact and health care seeking activity, independent of typical nonflare and overall pelvic pain levels. RESULTS: trends .0039 to < .0001) in analyses adjusted…

PURPOSE: We sought to systematically review and summarize the peer-reviewed literature on urologic chronic pelvic pain syndrome flares, including their terminology, manifestation, perceived triggers, management and prevention strategies, impact on quality of life, and insights into pathophysiologic mechanisms, as a foundation for future empirical research. MATERIALS AND METHODS: We searched 6 medical databases for articles related to any aspect of symptom exacerbations for interstitial cystitis/bladder pain syndrome and chronic prostatitis/chronic pelvic pain syndrome. A total of 1486 abstracts and 398 full-text articles were reviewed, and data were extracted by at least 2 individuals. RESULTS: Overall, we identified 59 articles, including 36 qualitative, cross-sectional, or case-control; 15 cohort-based; and 8 experimental articles. The majority of studies described North American patients with confirmed diagnoses. "Flare" was a commonly used term, but additional terminology (eg, exacerbation) was also used. Most flares involved significant increases in pain intensity, but less…

PURPOSE: With uniform modern approaches to adult acquired buried penis reconstruction, this study provides updated results on surgical outcomes for complex cases while evaluating the relative influence of medical, surgical, and socioeconomic factors on these results. MATERIALS AND METHODS: Retrospective review was conducted of all patients undergoing initial buried penis reconstruction including escutcheonectomy and penile skin grafting at 1 tertiary center from 2015 through 2022. Summary scores for frailty and socioeconomic status were calculated with the Modified Frailty Index and Area Deprivation Index, respectively. RESULTS: = .005). CONCLUSIONS: The modern approach to complex buried penis reconstruction results in a low revision rate; however, low-grade complications are frequent. Patient frailty identifies those at highest risk for complication, offering an opportunity for counseling and preoperative preparation.

PURPOSE: Genetic testing may alter clinical management for individuals with metastatic prostate cancer by identifying additional therapies. Traditional counseling models are unlikely to enable time-sensitive therapeutic decision-making. This study aimed to determine the feasibility and clinical impact of an alternative hereditary genetic testing model. MATERIALS AND METHODS: As part of a multicenter, single-arm prospective trial, individuals with advanced prostate cancer were referred by their oncologist for testing of 14 genes associated with hereditary prostate cancer. Pretest education (brochure and video) was provided in the oncology clinic. Questionnaires assessing participant satisfaction with both pretest education and decision to undergo genetic testing were collected. A genetic counselor contacted participants by phone to obtain family history and discuss results. Medical records were queried to determine whether a change in clinical management was discussed. RESULTS: Of 501 participants consented to germline analysis, 51 (10.2%) had at least 1 pathogenic/likely pathogenic…

PURPOSE: Reported rates of urethral stricture development after artificial urinary sphincter erosion are highly variable. We hypothesized that the risk of stricture is commensurate with the degree of erosion. MATERIALS AND METHODS: We reviewed our prospectively maintained quality improvement database for all patients with artificial urinary sphincter erosion from 2011 to 2022. The incidence of postoperative stricture development was compared to the severity of erosion using a graded scale: 1, <25% circumference; 2, 25%-50% circumference; 3, >50% and <100% circumference; and 4, 100% circumference. From 862 artificial urinary sphincter surgeries, 102 erosion cases were identified, and 63 with documented erosion severity were included for analysis. Additional analysis was performed on 28 cases without documented erosion severity for validation. RESULTS: < .01) and nearly every stricture occurred in the setting of prior radiation (21 of 22; 95.5%). In the validation group, 10 (35.7%) developed stricture, mostly in the setting of radiation (8 of 10; 80%). Overall, 29 of 32 (90.6%) cases…

PURPOSE: We identify correlates and clinical outcomes of cystitis cystica, a poorly understood chronic inflammatory bladder change, in women with recurrent urinary tract infections. MATERIALS AND METHODS: A retrospective, observational cohort of women with recurrent urinary tract infections who underwent cystoscopy (n=138) from 2015 to 2018 were identified using electronic medical records. Cystitis cystica status was abstracted from cystoscopy reports and correlations were identified by logistic regression. Urinary tract infection-free survival time associated with cystitis cystica was evaluated by Cox proportional hazards regression. Exact logistic regression was used to identify factors associated with changes to cystitis cystica lesions on repeat cystoscopy. Biopsies of cystitis cystica lesions were examined by routine histology and immunofluorescence. RESULTS: Fifty-three patients (38%) had cystitis cystica on cystoscopy. Cystitis cystica was associated with postmenopausal status (OR: 5.53, 95% CI: 1.39-37.21), pelvic floor myofascial pain (6.82, 1.78-45.04), having ≥4 urinary…

PURPOSE: We evaluate the applicability of the International Index of Erectile Function in young men with spina bifida and identify spina bifida-specific sexual experiences not captured by this measure. MATERIALS AND METHODS: Semistructured interviews were conducted between February 2021 and May 2021 with men ≥18 years of age with spina bifida. The International Index of Erectile Function was completed by participants, and perspectives on its applicability were discussed. Participant experiences and perspectives around sexual health were discussed to identify aspects of the sexual experience not well captured by the International Index of Erectile Function. Demographic and clinical characteristics were obtained from a patient survey and chart review. Conventional content analysis framework was used for transcript coding. RESULTS: Of 30 eligible patients approached, 20 participated. Median age was 22.5 years (range 18-29), and 80% had myelomeningocele. Most identified as heterosexual (17/20, 85%), were not in a relationship (14/20, 70%), and were not currently sexually active (13/20,…

PURPOSE: Urge urinary incontinence is the involuntary leakage of urine associated with a sudden compelling urge to void. A previous study found an association between urge urinary incontinence and household income, indicating that social determinants of health may influence urge urinary incontinence. Food insecurity is a relevant social determinant of health, as a diet with bladder irritants may worsen urge urinary incontinence symptoms. This study aimed to investigate the association between urge urinary incontinence and food insecurity. MATERIALS AND METHODS: We collected data from the 2005-2010 cycles of the National Health and Nutrition Examination Survey, a nationally representative health survey administered by the Centers for Disease Control and Prevention. The association between urge urinary incontinence and food insecurity was analyzed using survey-weighed logistic regression with adjustments for demographic, socioeconomic status, behavioral, and medical comorbidities covariates. RESULTS: < .001). When comparing diets, food-insecure participants reported significantly less…

PURPOSE: Prostatic urethral lift with UroLift is a minimally invasive approach to treat symptomatic benign prostatic hypertrophy. This device causes artifacts on prostate magnetic resonance images. Our aim was to evaluate the impact of artifact on prostate magnetic resonance image quality. MATERIALS AND METHODS: This was a single-center retrospective review of patients with UroLift who subsequently had prostate magnetic resonance imaging. Two readers graded UroLift artifact on each pulse sequence using a 5-point scale (1-nondiagnostic; 5-no artifact). Prostate Imaging Quality scores were assigned for the whole data set. The volume of gland obscured by artifact was measured. Linear and logistic regression models were used to identify predictors of poor image quality. RESULTS: < .001). CONCLUSIONS: UroLift artifact negatively affects prostate magnetic resonance image quality with greater impact in the mid-basal transition zone, obscuring a third of the gland on diffusion-weighted images. Patients considering this procedure should be counseled on the impact of this device on image…

PURPOSE: Postoperative education and symptom tracking are essential following cystectomy to reduce readmission rates and information overload. To address these issues, an internet-based tool was developed to provide education, alerts, and symptom tracking. We aimed to evaluate the tool's feasibility, acceptability, and impact on complication and readmission rates. MATERIALS AND METHODS: Thirty-three eligible patients over 18 years old scheduled for cystectomy were enrolled. Patients were asked to use the mobile health (mHealth) tool daily for the first 2 weeks, then less frequently up to 90 days after discharge. Descriptive statistics were used to summarize study variables. Feasibility was defined as at least 50% of patients using the tool once a week, and acceptability as patient satisfaction of > 75%. RESULTS: = .21). CONCLUSIONS: The study showed that the electronic mobile health intervention for patients undergoing cystectomy was feasible, acceptable, and provided valuable educational content and symptom management. Future larger studies are needed to determine the tool's…

PURPOSE: We investigated the efficacy and safety of high-dose vitamin D supplementation (VDS) plus standard urotherapy (SU) in managing overactive bladder dry in children. MATERIALS AND METHODS: A 3-arm, randomized clinical trial was performed at an academic center in China between January 2023 and June 2023. Eligible patients (n=303) were randomized to receive 8 weeks of high-dose VDS (vitamin D3 drops encapsulated as soft capsules, 2400 IU/d) plus SU (VDS + SU group; n=100), solifenacin (5-10 mg/d) plus SU (SOL + SU group; n=102), or SU alone (SU group; n=101). Reduction in voiding frequency was the primary outcome. Secondary outcomes encompassed improvement in urgency, nocturia, quality of life score, pediatric lower urinary tract symptom score, and participant satisfaction. Treatment-emergent adverse events were recorded within each group. RESULTS: < .001) after intervention. The VDS + SU group also showed the greatest improvement in quality of life and pediatric lower urinary tract symptom scores. Patient satisfaction was similar between the SOL + SU and SU groups. The VDS + SU…

PURPOSE: There are limited pooled data showing the impact of visceral metastasis on oncologic outcomes in metastatic prostate cancer patients treated with combination systemic therapies. We aimed to analyze and compare the efficacy of combination systemic therapies in metastatic hormone-sensitive prostate cancer and metastatic castration-resistant prostate cancer with or without visceral metastasis. MATERIALS AND METHODS: Three databases were queried in July 2022 for randomized, controlled trials analyzing metastatic prostate cancer patients treated with combination systemic therapy (androgen receptor signaling inhibitor and/or docetaxel plus androgen deprivation therapy) to standard of care. We analyzed the association between presence of visceral metastases and efficacy of systemic therapies in metastatic hormone-sensitive prostate cancer and metastatic castration-resistant prostate cancer patients. The main and secondary outcomes of interest were overall survival and progression-free survival, respectively. Formal meta-analysis using fixed-effect model and network meta-analysis…

PURPOSE: Previous work in urology has shown that men have higher h-indices than women. However, the degree to which h-indices vary by gender within urological subspecialties has not been well defined. Herein, we assess gender differences in h-index among different subspecialties. MATERIALS AND METHODS: Demographics were recorded for academic urologists using residency program websites as of July 2021. Scopus was queried to identify h-indices. Gender differences in h-index were estimated from a linear mixed-effects regression model with fixed effects for gender, urological subspecialty, MD/PhD status, years since first publication, interactions of subspecialty with years since first publication, and interactions of subspecialty with gender and random effects for AUA section and institution nested within AUA section. The Holm method was used to adjust for multiplicity (7 hypothesis tests). RESULTS: Of 1,694 academic urologists from 137 institutions, 308 were women (18%). Median years since first publication was 20 for men (IQR 13, 29) and 13 for women (IQR 8, 17). Among all academic…

PURPOSE: It is unknown whether compliance with recommended monitoring tests during observation of localized prostate cancer has changed over time. MATERIALS AND METHODS: We performed a retrospective cohort study of Medicare beneficiaries diagnosed with low- or intermediate-risk prostate cancer in 2004-2016 who were initially managed with observation for a minimum of 12 months. The primary objective was to examine rates of PSA testing, prostate biopsy, and prostate MRI. We used multivariable mixed effects Poisson regression to determine whether rates of PSA testing and prostate biopsy increased over time. In addition, we identified clinical, sociodemographic, and provider factors associated with the frequency of monitoring tests during observation. RESULTS: We identified 10,639 patients diagnosed at a median age of 73 (IQR 69-77) years. The median follow-up time was 4.3 (IQR 2.7-6.6) years after diagnosis. Among patients managed without treatment for 5 years, 98% received at ≥1 PSA test, 48.0% ≥1 additional prostate biopsy, and 31.0% ≥1 prostate MRI. Among patients managed with…

PURPOSE: We sought to examine the association of extraprostatic extension (EPE) with biochemical recurrence (BCR) separately in men with Grade Group (GG) 1 and GG2 prostate cancer (PCa) treated with radical prostatectomy. MATERIALS AND METHODS: We reviewed our institutional database of patients who underwent radical prostatectomy for PCa between 2005 and 2022 and identified patients with GG1 and GG2 disease on final pathology. Fine-Gray competing risk models with an interaction between EPE (yes vs no) and GG (GG1 vs GG2) were used to examine the relationship between disease group and BCR-free survival. RESULTS: The cohort consisted of 6309 men, of whom 169/2740 (6.2%) with GG1 disease had EPE while 1013/3569 (28.4%) with GG2 disease had EPE. Median follow-up was 4 years. BCR occurred in 400/6309 (6.3%) patients. For men with GG1, there was no statistically significant difference in BCR-free survival for men with vs without EPE (subdistribution HR = 0.88; 95% CI: 0.37-2.09). However, for GG2 patients BCR-free survival was significantly worse for those with vs without EPE…

PURPOSE: We evaluate the efficacy and safety profiles of currently available conservative management options for penile and urethral lichen sclerosus. MATERIALS AND METHODS: A systematic review of existing literature on lichen sclerosus was conducted utilizing the PubMed, Embase, and Web of Science databases. References were assessed for relevance to nonsurgical management of male genital lichen sclerosus by title and abstract by 3 independent reviewers, then reviewed in full and in duplicate by 5 independent reviewers. RESULTS: laser. We also briefly discuss the limited studies on the use of oral acitretin and polydeoxyribonucleotide injections. Outcomes assessed include symptoms, clinical appearance, quality of life, sexual satisfaction, adverse effects, and long-term efficacy of treatment. CONCLUSIONS: Topical corticosteroids remain the mainstay of conservative management of penile and urethral lichen sclerosus, with current literature supporting the use of other therapies such as tacrolimus and platelet-rich plasma as alternatives or adjuvant treatments when escalation of…

PURPOSE: Transrectal prostate biopsy is a common ambulatory procedure that can result in pain and anxiety for some men. Low-dose, adjustable nitrous oxide is increasingly being used to improve experience of care for patients undergoing painful procedures. This study seeks to evaluate the efficacy and safety of low-dose (<45%) nitrous oxide, which has not been previously established for transrectal prostate biopsies. MATERIALS AND METHODS: A single-institution, prospective, double-blind, randomized, controlled trial was conducted on patients undergoing transrectal prostate biopsies. Patients were randomized to receive either self-adjusted nitrous oxide or oxygen, in addition to routine periprostatic bupivacaine block. Nitrous oxide at levels between 20% and 45% were adjusted to patients' desired effect. Patients completed a visual analog scale for anxiety, State Trait Anxiety Inventory, and a visual analog scale for pain immediately before and after biopsy. The blinded operating urologist evaluated ease of procedure. Periprocedural vitals and complications were assessed. Patients…

PURPOSE: Overactive bladder (OAB) may be attributed to dysfunction in supraspinal brain circuits. Overactive bladder participants enrolled in the LURN (Symptoms of Lower Urinary Tract Dysfunction Research Network) study reported sensations of urinary urgency during a bladder-filling paradigm while undergoing brain functional MRI to map supraspinal dysfunction. MATERIALS AND METHODS: OAB participants and controls (CONs) completed 2 resting-state functional MRI scans following consumption of 350 mL water. Scans were conducted at fuller and emptier bladder states, interleaved with voiding. Urgency ratings (0-10) were assessed. Patterns of urgency during bladder filling were investigated using latent class trajectory models. Clusters of participants encompassing each pattern (ie, subtype) were derived from aggregated groups of OAB and CON independent of diagnosis. RESULTS: Two distinct patterns of urgency trajectories were revealed: first subtype with OAB and CON who were unresponsive to bladder filling (OAB-1 and CON-1) and second highly responsive subtype predominantly containing OAB…

PURPOSE: We determined if serial screening ultrasounds are beneficial in evaluating for the development of Zinner syndrome in males with a congenital solitary kidney. MATERIALS AND METHODS: All patients included had their congenital solitary kidney diagnosed at <20 years of age and had to be ≥20 at their last visit. Individuals were seen annually, with pelvic ultrasounds to screen for mesonephric duct cysts obtained at birth and every year of age, divisible by 5. RESULTS: = .0198). Of symptomatic patients, 75% (8/12) had abnormal uroflows. Complete urodynamic studies revealed findings consistent with bladder outlet obstruction in 38% (3/8), equivocal for obstruction in 24% (2/8), and detrusor underactivity in 38% (3/8). Cyst excision effectively resolved voiding symptoms that were obstructive in etiology but failed to resolve symptoms in patients with detrusor underactivity. CONCLUSIONS: Serial ultrasound evaluations reveal that cyst growth to ≥5 cm in size is highly related to the onset of clinical symptoms, with the resolution of voiding symptoms by cyst excision directly…

PURPOSE: Glans vascular compromise had previously been considered a rare but devastating complication of the subcoronal incision for inflatable penile prosthesis surgery. Here, we describe the largest series of subcoronal implants to date to assess contemporary complication rates. MATERIALS AND METHODS: A retrospective review of subcoronal prosthesis placements by a single surgeon from Seoul, South Korea, was performed. Patients were randomly assigned either Coloplast Titan or AMS 700 device per institutional practice. RESULTS: < .01). Five cases (0.5%) of distal penile skin necrosis were reported in patients who had previously been circumcised. Of these, 3 were managed successfully with wet-to-dry dressing, 1 required skin grafting, and 1 required device explant. Device infection without incisional compromise occurred in 2 cases (0.2%). There were no instances of glans necrosis or ischemia observed in this cohort. Of the first-time implants (817, 90.9%), most (62.3%) were successfully completed under local anesthetic alone, with the remainder of surgeries completed with the…

PURPOSE: Antibiotic-refractory recurrent urinary tract infections are challenging to manage. Prior studies have shown that, in selected patients, electrofulguration of cystitis may disrupt potential nidus of recurrent urinary tract infections. We report on long-term outcomes of electrofulguration in women with at least 5 years of follow-up. MATERIALS AND METHODS: Following Institutional Review Board approval, we analyzed a cohort of nonneurogenic women with ≥3 symptomatic recurrent urinary tract infections/y and inflammatory lesions on cystoscopy who underwent electrofulguration, excluding those with alternate identifiable etiology for recurrent urinary tract infections or less than 5-year follow-up. Preoperative characteristics, antibiotic regimens, and annual urinary tract infections were reported. Primary outcome was clinical cure (0-1 urinary tract infection/y), improvement (>1 and <3/y) or failure (≥3/y) at last follow-up. Secondary outcomes included need for antibiotics or repeat electrofulguration. A subanalysis was performed for women with >10-year follow-up. RESULTS: <…

PURPOSE: This study utilizes CARDIA (Coronary Artery Risk Development in Young Adults) cohort study data to examine whether (1) family-based adverse childhood experiences, recalled by women aged 32 to 47, are associated with lower urinary tract symptoms and their impact, a composite variable with 4 levels (bladder health and mild, moderate, or severe lower urinary tract symptoms/impact), and (2) extensiveness of women's social networks in adulthood attenuates an association between adverse childhood experiences and lower urinary tract symptoms/impact. MATERIALS AND METHODS: In 2000-2001, frequency of adverse childhood experiences exposure was retrospectively assessed. In 2000-2001, 2005-2006, and 2010-2011, extensiveness of social networks was assessed; scores were averaged. In 2012-2013, lower urinary tract symptoms/impact data were collected. Logistic regression analyses examined whether adverse childhood experiences, extensiveness of social networks, and their interaction were associated with lower urinary tract symptoms/impact, adjusting for age, race, education, and parity…
