Urological outcomes in adult females born with anorectal malformation or Hirschsprung disease.

INTRODUCTION: Women born with anorectal malformation (ARM) or Hirschsprung disease (HD) may have impaired urologic function resulting in sequelae in adulthood. This study assessed and compared self-reported urinary outcomes in adult females born with ARM or HD to a reference population. METHODS: This was an IRB approved, cross-sectional study of female-born patients with ARM or HD, who completed surveys between November 2021 and August 2022. Female patients between the ages of 18 and 80 years were included. Lower Urinary Tract Symptom Questionnaires were administered through REDCap and the responses were compared to a reference population using Chi-squared or Fisher's exact tests. RESULTS: Sixty-six born female patients answered the questionnaires, two of them identified as non-binary. The response rate was 76%. Median age was 31.6 years. The majority were born with cloaca (56.3%), followed by other type of ARMs (28.1%), complex malformation (9.4%), and HD (6.3%). A history of bladder reconstruction was present for 26.6%. Catheterization through a channel or native urethra was present in 18.8%. Two had ureterostomies and were excluded from the analysis. Seven had chronic kidney disease or end-stage renal disease, three with a history of kidney transplantation. Patients with cloaca had significantly higher rates of urinary incontinence, urinary tract infection, and social problems due to impaired urological functioning, when compared to an age-matched reference population (Table 3). CONCLUSION: This study emphasizes the need for a multi-disciplinary team that includes urology and nephrology following patients with ARM long term, especially within the subgroup of cloaca. LEVEL OF EVIDENCE: III.

Urinary Continence Outcomes in Classic Bladder Exstrophy: A Long-Term Perspective.

PURPOSE: We investigated surgical approaches to urinary incontinence and long-term continence outcomes after successful bladder reconstruction in a heterogeneous patient population with classic bladder exstrophy. We hypothesized that while most patients will achieve urinary continence after surgery, only a select group will void volitionally per urethra. MATERIALS AND METHODS: An institutional database of 1,323 patients with exstrophy-epispadias complex was reviewed for patients with classic bladder exstrophy who underwent successful bladder closure and a subsequent continence procedure between 1975 and 2017. Procedures included bladder neck reconstruction, bladder neck reconstruction with augmentation cystoplasty or continent catheterizable stoma, and bladder neck closure with continent catheterizable stoma. Cloacal exstrophy, epispadias and variant exstrophy cases were excluded from analysis. Continence at last followup was defined as a dry interval of 3 or more hours without nighttime leakage. Those patients with more than 3 months of followup were assessed. RESULTS: Overall 432 patients underwent successful bladder closure (primary 71.5%, repeat 28.5%) and a urinary continence procedure. At last followup 162 (37%) underwent bladder neck reconstruction, 76 (18%) underwent bladder neck reconstruction with augmentation cystoplasty or continent catheterizable stoma, 173 (40%) underwent bladder neck closure with continent catheterizable stoma and 18 underwent other procedures. Median followup from the first continence procedure was 7.2 years (IQR 2.3-13.7). Continence was assessed in 350 patients. After isolated bladder neck reconstruction 91 of 142 patients were continent (64%, 95% CI 56-72). After bladder neck closure with continent catheterizable stoma 124 of 133 patients evaluated were continent (93%, 95% CI 87-97). CONCLUSIONS: Most patients with classic bladder exstrophy require multiple reconstructive procedures to achieve continence. Only about 25% of patients are expected to void normally per urethra without reliance on catheterization or urinary diversion.

Adherence to National Comprehensive Cancer Network® Guidelines for Testicular Cancer.

PURPOSE: Testicular cancer is the most common malignancy among young men and well established treatment guidelines exist to optimize outcomes. We characterized errors in the management of testicular cancer observed among patients seen at 3 referral centers in the United States. MATERIALS AND METHODS: We retrospectively reviewed data from 593 patients presenting with testicular cancer to 3 academic medical centers from 2007 to 2016. Nonguideline directed care was defined as management differing from National Comprehensive Care Network guideline recommendations. Cases of nonguideline directed care were systematically described. Patient and tumor characteristics were compared between guideline directed care and nonguideline directed care. Multivariable logistic regression was used to identify predictors of nonguideline directed care, and Cox regression modeling was used to assess the association between nonguideline directed care and relapse-free survival. RESULTS: Nonguideline directed care was identified in 177 of 593 (30%) patients. Inappropriate imaging (44%) and overtreatment (40%) were the most common classifications. Misdiagnosis (24%) and under treatment (16%) occurred relatively frequently, while inappropriate treatment (6%) was rare. Multivariable Cox regression modeling controlling for race, tumor stage and tumor histology identified nonguideline directed care as a significant predictor of relapse (HR 2.49, 95% CI 1.61-3.85, p <0.01). CONCLUSIONS: Nonguideline directed care of patients with testicular cancer is common, most frequently in the form of inappropriate imaging and overtreatment. Nonguideline directed care leads to delayed definitive therapy, unnecessary morbidity and higher rates of relapse.

Pathological analysis of the prostatic anterior fat pad at radical prostatectomy: insights from a prospective series.

OBJECTIVE: To assess factors associated with lymphatic drainage and lymph node (LN) metastasis to the prostatic anterior fat pad (PAFP) in men with prostate cancer and the utility of routine PAFP analysis at the time of radical prostatectomy (RP). PATIENTS AND METHODS: Our institution began to prospectively collect PAFP tissue in 2010. The PAFP was removed at the time of RP and sent as a pathological specimen separate from the pelvic LNs and prostate. Consecutive RPs performed at our institution in which the PAFP was removed were reviewed to determine the rate of LNs in the PAFP, the rate of metastatic LNs in the PAFP, and the association of metastatic PAFP LN with clinical and pathological features. The impact on biochemical recurrence (BCR) was assessed with a Cox's proportional hazard model. RESULTS: In all, 2 413 PAFP specimens were available for analysis. LNs were found in the PAFP in 255 (10.6%) cases and metastatic LNs in the PAFPs were found in 14 (0.6%) cases. Metastatic PAFP LNs were associated with anterior tumours in 11 of the 14 cases (P = 0.01), and were present only in preoperative D'Amico intermediate- (six of 14) and high- (eight of 14) risk patients (P < 0.001). Metastatic PAFP LNs were associated with extraprostatic disease in 13 of the 14 cases, although concomitant pelvic LN involvement was present in only four of the 14 cases. With a mean follow-up of 1.5 years, three of the 14 patients with metastatic PAFP LN developed BCR. Positive LN involvement in either the pelvic LN or PAFP had worse BCR than LN-negative patients (P < 0.001); however, there was no difference in BCR between patients with positive pelvic LN and positive PAFP LN (P = 0.5). CONCLUSION: Metastatic PAFP LNs are rare and always occur in the presence of other adverse pathological features. The routine pathological analysis of PAFP as a separate specimen, especially in low-risk disease, may not be warranted.

Extent of renal vein invasion influences prognosis in patients with renal cell carcinoma.

OBJECTIVE: To compare oncological outcomes for segmental vs main renal vein invasion (RVI) in patients with renal cell carcinoma (RCC). PATIENTS METHODS: Patients undergoing extirpative surgery for RCC at our institution between 2003 and 2013 were stratified into five groups according to clinical stage: T2 (n = 135), T3a with fat invasion (n = 185), T3a with segmental RVI (n = 87), T3a with main RVI (n = 64) and T3b (n = 40). Kaplan-Meier survival analysis and multivariable Cox regression were performed to determine the impact of segmental RVI on recurrence-free survival (RFS) and cancer-specific survival (CSS). Harrell's c index was used to compare the prognostic accuracy of current and proposed staging models. RESULTS: At a median follow-up of 37 months, both RFS and CSS were significantly worse for patients with main RVI as compared with segmental RVI (P = 0.03 and P = 0.009, respectively). On multivariable analysis, main RVI had inferior RFS (hazard ratio [HR] 2.3, 95% confidence interval [CI] 1.1-4.4; P = 0.03] and CSS (HR 3.5, 95% CI 1.3-9.9; P = 0.02) compared with segmental RVI. Sub-stratifying T3a disease by separating segmental and main RVI improved prognostic accuracy compared with the current staging system for CSS (c indices 0.66 vs 0.59) and RFS (0.70 vs 0.60). CONCLUSIONS: Main RVI is independently associated with worse RFS and CSS than segmental RVI. These findings may have significance for patient counselling and future staging guidelines.

A comparative analysis of robotic vs laparoscopic retroperitoneal lymph node dissection for testicular cancer.

OBJECTIVE: To compare the safety and perioperative outcomes of robotic retroperitoneal lymph node dissection (R-RPLND) vs laparoscopic RPLND (L-RPLND). PATIENTS AND METHODS: Our Institutional Review Board-approved retrospective testicular cancer registry was queried for patients who underwent a primary unilateral R-RPLND or L-RPLND by a single surgeon for a stage I testicular non-seminomatous germ cell tumour. Groups were compared for differences in baseline and outcome variables. RESULTS: Between July 2006 and July 2014, 16 R-RPLND and 21 L-RPLND cases were performed by a single surgeon. Intra- and perioperative outcomes including operative time, estimated blood loss, lymph node yield, complicate rate, and ejaculatory status were similar between groups (all P > 0.1). CONCLUSIONS: As an early checkpoint, R-RPLND appears comparable to L-RPLND in terms of safety and perioperative outcomes. It remains unclear if R-RPLND offers any tangible benefits over standard laparoscopy.

Barriers to Transitional Care in Spina Bifida.

The health care needs children with spina bifida evolve over their lifetime; continued, regular contact with appropraitely trained, multidisciplinary providers is crucial to a patient's health and quality of life. Substantial research has been conducted to improve the transition process starting at an early age; however, there continue to be strong barriers to successful transition. This article reviews key aspects of the care of patients with spina bifida, the impact of inadequate transition to adult care, barriers to transition, and offers a potential vision for the future.

Long term outcomes in classic bladder exstrophy - The adult picture.

With continued improvements in medical care and surgical reconstruction, more patients with classic bladder exstrophy (CBE) are living into adulthood, than ever before. With improved survival, a greater emphasis on adult issues and improving quality of life (QOL) for these individuals is of increasing importance. This review aims to summarize data on long-term considerations for the adult with exstrophy and to highlight areas of future research and collaboration. Key conclusions are that continence or dryness are achievable alongside the ability to enjoy sexual relationships and a good quality of life.

Endometriosis in a Prepubertal Patient with 46,XY Difference in Sex Development: A Case Report.

INTRODUCTION: Endometriosis typically presents in postmenarchal patients with cyclic and acyclic pelvic pain. However, there are reports of endometriosis in premenarchal patients. CASE: We report a 10-year-old individual with 46,XY difference of sex development who was found to have endometriosis at the time of laparoscopic gonadectomy for gonadoblastoma. CONCLUSIONS: Although rare, endometriosis can occur in 46,XY individuals prior to puberty, highlighting the complex origin of the disease.

Adult urological outcomes for patients with anorectal malformation.

Anorectal malformations (ARM) are rare congenital anomalies characterized by a spectrum of defects resulting in the absence of a normal anal opening with or without fistula. Urogenital involvement is common, and the fistulous tract may terminate in the genitourinary system in males or within gynecological structures in females. Surgical reconstruction occurs early in life and survival of these patients to adulthood is the norm. There has, therefore, been increased focus on their long-term outcomes to better anticipate and treat the sequelae that may impact their health and well-being as this population ages. For urologists, urinary health, sexual function, and fertility outcomes are of particular interest among this population. This article aims to provide a review of urological, sexual, and fertility outcomes for individuals born with ARM with a focus on key issues that may occur later in life to ensure adequate counseling, screening, and treatment.

Considerations and Outcomes for Adolescents and Young Adults With Cloacal Anomalies: A Scoping Review of Urologic, Colorectal, Gynecologic and Psychosocial Concerns.

The objective of this scoping review is to provide a summary of the current literature regarding adolescents and young adults with histories of cloacal anomalies. Preferred Reporting Items for Systematic Reviews and Meta-analysis Extension for Scoping Reviews were used. Data were categorized into four domains-urologic, colorectal, gynecologic/obstetric, and sexual/psychosocial. The current literature has poor study quality and mostly consists of retrospective studies of small cohorts with varying definitions of outcomes. Women with cloacal anomalies are at high risk for urologic dysfunction but can maintain kidney health and achieve social continence with medical and surgical management. Sexual function and adult healthcare transition are areas ripe for improved future research.

Management of the urological tract in children with anorectal malformations - a contemporary review.

Anorectal malformations (ARMs) consist of a broad spectrum of congenital anomalies that are associated with an equally wide variety of urological abnormalities, often with increasing incidence as the severity of the ARM increases. The importance of urologic involvement in the care of ARM patients has been noted for decades and is critical from birth to adulthood. Urology must be involved in the initial evaluation and operative care of the child as well as in monitoring and managing issues such as neurogenic bladder, renal disease, and eventually sexual function and fertility. Care of the ARM patient must be done through a multidisciplinary lens, with the urologist as a key player. This review will serve as an update on the management of the urologic tract in children with ARM.

Unrepaired cloacal exstrophy in an adult: Medical and ethical considerations.

Cloacal exstrophy, also known as OEIS complex, is a rare condition, comprised of severe congenital anomalies. This case report describes a 24-year-old 46,XY individual who had repair of the omphalocele at birth, but has remained with an unrepaired bladder exstrophy. This case highlights the intersections between medical decision-making, individualized management of complex patients, and ethical considerations for adults lacking capacity.

Complications of delayed and newborn primary closures of classic bladder exstrophy: Is there a difference?

INTRODUCTION: The authors aim to compare single institutional 30-day complication rates between delayed and neonatal closure of classic bladder exstrophy (CBE). MATERIALS AND METHODS: An institutional database of 1415 exstrophy-epispadias patients was reviewed retrospectively for CBE patients who underwent primary closures at the authors' institution between 1990 and 2020. Patients were identified as having received either neonatal or delayed (at age >28 days) closures. All 30-day complications were recorded, including wound infection and dehiscence, genitourinary and non-genitourinary infections, bowel obstruction, blood transfusions, and others. Descriptive statistics were performed to summarize patient level data. Categorical variables were reported by count and percentages and were compared using Exact Cochran-Armitage trend analysis by decade, or with Fisher's Exact Test and Chi-square test when directly comparing categories and outcomes. Continuous variables were analyzed via Mann Whitney U and one-way ANOVA as appropriate. RESULTS: The cohort included 145 patients: 50 delayed and 95 neonatal closures. The total complication rate was 58% in delayed closures compared to 48.4% for neonatal closures (p = 0.298), with the majority being Clavien-Dindo grade I or II. Excluding blood transfusion, complication rates fell to 26% and 34.7% in delayed and neonatal closures, respectively (p = 0.349). The most common single complication was unplanned post-operative blood transfusion (38% delayed; 26.3% neonatal; p = 0.34), followed by pyelonephritis (2% delayed; 8.4% neonatal), and urinary fistula (6% delayed; 1.1% neonatal). Grade III Clavien-Dindo complications occurred in 2% delayed and 7.4% neonatal groups (n = 1; n = 7 respectively; p = 0.263). A single delayed patient had grade IV complications compared to three neonatal patients (p = 0.66). CONCLUSIONS: Delayed primary closure has become a frequently performed alternative in the modern treatment of bladder exstrophy for patients who do not undergo newborn closure because of prohibitive circumstances or surgeon's discretion. The majority of the complications associated with delayed closure are a low Clavien-Dindo grade and easily managed during the postoperative inpatient hospital stay. Families should be counseled about the possibility of minor, conservatively managed complications and likelihood of a blood transfusion with osteotomy.

The exstrophy experience: A national survey assessing urinary continence, bladder management, and oncologic outcomes in adults.

INTRODUCTION AND OBJECTIVE: The bladder exstrophy-epispadias complex (BEEC) is a rare spectrum of congenital genitourinary malformations with an incidence of 1:10,000 to 1:50,000. Advances in reconstructive surgical techniques have improved clinical outcomes, but there is a paucity in data about disease sequela in adulthood. This is the largest survey to date in the United States exploring the urinary continence, bladder management, and oncologic outcomes in adults with BEEC. METHODS: Respondents were over the age of 18 with a diagnosis of bladder exstrophy, cloacal exstrophy, or epispadias. They were treated at the authors' institution, included in the Association for the Bladder Exstrophy Community (A-BE-C) mailing list, and/or engaged in A-BE-C social media. A survey was created using uniquely designed questions and questionnaires. Survey responses between May 2020 and July 2020 were processed using Research Electronic Data Capture (REDCap). Quantitative and qualitative statistics were used to analyze the data with significance at p < 0.05. RESULTS: A total of 165 patients completed the survey. The median age was 31.5 years (IQR 25.9-45.9). Many patients considered themselves continent of urine, with a median satisfaction score of 74 (IQR 50-97) on a scale from 0 (consider themselves to be completely incontinent) to 100 (consider themselves to be completely continent). There was less leakage among those with a continent urinary diversion compared to those who void or catheterize per urethra (p = 0.003). Patients with intestinal-urinary tract reconstruction, such as augmentation cystoplasty or neobladder creation, were more likely to perform bladder irrigations (p = 0.03). Patients with continent channels were more likely to report UTI than all other forms of bladder management (89.0% vs. 66.2%, p = 0.003). Three (1.9%) patients were diagnosed with bladder cancer. A small portion of patients (27.2%) were given bladder cancer surveillance recommendations by a physician. DISCUSSION: Most patients achieved a satisfactory level of urinary continence, with the highest continence rates in those with a continent urinary diversion. Those with intestinal-urinary tract reconstruction were more likely to perform bladder irrigations, perhaps to avoid complications from intestinal mucous production. The rates of self-reported UTI and were higher in patients with continent channels, but recurrent UTIs were not affected by the type of genitourinary reconstruction. Bladder cancer exists in this population, highlighting the need for long-term follow-up. CONCLUSION: Most BEEC patients achieve a satisfactory level of urinary continence, with the best outcomes in those with a continent urinary diversion. This population requires long-term follow-up with a transitional urologist to ensure adequate oncologic care.

Achieving goal capacity for continence surgery: A cumulative event analysis of bladder exstrophy patients.

BACKGROUND: Following successful closure of patients with classic bladder exstrophy (CBE), the next major milestone is the establishment of urinary continence. Prior to determining the most appropriate continence surgery, it is imperative to reach an adequate bladder capacity minimum of 100 cc in order to make the decision between bladder neck reconstruction (BNR) or continent stoma, with or without augmentation cystoplasty (AC). OBJECTIVE: To examine the timing of when patients achieve threshold bladder capacity for BNR eligibility. We hypothesize most patients will achieve an adequate bladder capacity (100 cc) by 7 years old when continence surgeries will begin to be considered. STUDY DESIGN: An institutional database of 1388 exstrophy patients was retrospectively reviewed for CBE patients after successful primary bladder closure. Bladder capacities were measured via gravity cystography and data presented as descriptive statistics. The cohort was stratified by location, neonatal (≤28 days) or delayed closure period and osteotomy status. The bladder capacities were categorized to either reaching goal or not and a cumulative event analysis was performed. The event being reaching 100 cc capacity or greater and time being the number of years between bladder closure and attainment of goal capacity. RESULTS: 253 patients met inclusion criteria between 1982 and 2019. The majority were of male gender (72.9%), had their closure performed at the authors' institution (52.5%), within the neonatal period (80.7%), and without an osteotomy (51.7%). 64.9% of patients reached goal bladder capacity. There were no significant differences in those who did or did not achieve goal except for clinical follow up. Cumulative event analysis demonstrated a median time of 5.73 years (95% CI 5.2-6.20) corresponded with a 50% event probability of reaching goal capacity. Cox-proportional hazards showed location of closure was significantly associated with hazards of reaching goal bladder capacity (HR = 0.58, CI 0.40-0.85, p = 0.005). Based on this model, the median time to event would be 5.20 years (95% CI 4.76-5.80) for cases done at the authors' hospital and 6.26 years for those performed at an outside hospital (95% CI 5.77-7.24). CONCLUSIONS: These findings help surgeons counsel families appropriately on the odds of attaining goal capacity at various ages. For those who do not reach 100 cc by five years of age, it helps further characterize the odds of requiring a continent stoma with bladder augmentation and the best timing for reconstructive surgery in order to safely gain urinary continence. Families may also be assured that most patients would have the breadth of surgical options when it comes to continence as more than half of patients reached the bladder capacity threshold.

Adrenal pheochromocytoma in a patient with Lynch Syndrome.

Lynch Syndrome (LS), or hereditary non-polyposis colorectal cancer, is the most common cause of hereditary colorectal cancer. There are well described extra-colonic manifestations of LS, including gynecologic and upper urinary tract malignancies. Other extra-colonic manifestations of LS are less understood. Here we present an unusual case of a functional adrenal pheochromocytoma in a 31-year old man with LS.

Patient and in-hospital predictors of post-discharge opioid utilization: Individualizing prescribing after radical prostatectomy based on the ORIOLES initiative.

OBJECTIVE: Judicious opioid stewardship would match each patient's prescription to their true medical necessity. However, most prescribing paradigms apply preset quantities and clinical judgment without objective data to predict individual use. We evaluated individual patient and in-hospital parameters as predictors of post-discharge opioid utilization after radical prostatectomy (RP) to provide evidence-based guidance for individualized prescribing. METHODS: A prospective cohort of patients who underwent open or robotic RP were followed in the Opioid Reduction Intervention for Open, Laparoscopic, and Endoscopic Surgery (ORIOLES) initiative. Baseline demographics, in-hospital parameters, and inpatient and post-discharge pain medication utilization were tabulated. Opioid medications were converted to oral morphine equivalents (OMEQ). Predictive factors for post-discharge opioid utilization were analyzed by univariable and multivariable linear regression, adjusting for opioid reduction interventions performed in ORIOLES. RESULTS: Of 443 patients, 102 underwent open and 341 underwent robotic RP. The factors most strongly associated with post-discharge opioid utilization included inpatient opioid utilization in the final 12 hours before discharge (+39.6 post-discharge OMEQ if inpatient OMEQ was >15 vs. 0), maximum patient-reported pain score (range 0-10) in the 12 hours before discharge (+27.6 OMEQ for pain score ≥6 vs. ≤1), preoperative opioid use (+76.2 OMEQ), and body mass index (BMI; +1.4 OMEQ per 1 kg/m2). A final predictive calculator to guide post-discharge opioid prescribing was constructed. CONCLUSIONS: Following RP, inpatient opioid use, patient-reported pain scores, prior opioid use, and BMI are correlated with post-discharge opioid utilization. These data can help guide individualized opioid prescribing to reduce risks of both overprescribing and underprescribing.

Gender Representation Among Plenary Panel Speakers at the American Urological Association Annual Meeting.

OBJECTIVE: To examine trends in the representation of women in plenary panels at the American Urological Association (AUA) Annual Meeting. METHODS: A review of all plenary sessions from AUA Annual Meetings during 2017-2019 was performed. The number and proportion of invited moderators and panelists by gender were recorded and analyzed by the topic of each plenary session. We performed descriptive analyses and tested temporal trends in gender representation. RESULTS: A total of 168 plenary panels were held at the AUA meetings, 62 panels in 2017, 51 panels in 2018, and 55 panels in 2019. Overall, 59% of panels were all-male panels (61% in 2017, 67% in 2018, and 49% in 2019) with exclusively male moderators and panelists. There was no significant change in the proportion of all-male panels during the study period (P = .20). Among the 168 panels, 153 (91%) had a male moderator, and 107 (64%) had only male panelists. Seventy-five unique female speakers accounted for 90 (12%) of the 742 total panel speaking roles. There was significant variation in the proportion of female speakers among 6 plenary topics (P = .03); the overall proportion of all-male panels was highest for sexual medicine sessions (14 of 18 panels, 78%) and lowest for female pelvic medicine sessions (5 of 19 panels, 26%). CONCLUSION: Female representation in plenary panels at recent AUA Annual Meetings did not significantly change, with the majority of panels composed entirely of male speakers. Continued evaluation of these trends may inform efforts to achieve gender equality at national urology meetings.

Contemporary Assessment of the Most Cited Clinical, Basic Science, and Guidelines Papers in Urology: A Reference for Urology Journal Club.

OBJECTIVE: To perform bibliometric analysis of the top cited articles in urology as a guide for journal club article selection. METHODS: Bibliometric citation analysis was performed using Scopus. Tables illustrating the top cited clinical, basic science, and guidelines/position statements papers were constructed. Linear regression was used to determine association between h-index and number of citations. RESULTS: A total of 3,188,861 publications from 1788 to 2020 were analyzed. The top 100 cited clinical papers from 1788 to 2020, top 100 cited contemporary clinical papers from 2000 to 2020, top 25 cited basic science papers, and the top 25 cited guidelines/position statement papers were reported. Median number of citations in the top 100 cited clinical papers was 1463 (interquartile range 1186-1821). Memorial Sloan Kettering Cancer Center (12), Johns Hopkins University (6), and Harvard University (6) contributed the most top cited clinical papers in urology. Urologic oncology was the most represented subspecialty in both clinical (75%) and basic science (96%) papers. First author and last author h-index were found to correlate with the number paper citations in the top 100 cited clinical papers from 1788 to 2020 (first author ß:5.3, P= .003, last author ß:4.5, P= .03). Only 7% of the most cited clinical papers in urology were from female first authors, which was not statistically significantly different from those reported in prior publications published in 2009 and 2013. CONCLUSION: Contemporary citation analysis of indexed manuscripts in urology may serve as a valuable educational tool for urologists and trainees.
