Abstract
INTRODUCTION On June 24, 2022, the US Supreme Court issued its decision on Dobbs v Jackson Women's Health Organization (Dobbs). This decision had major implications on female reproductive choices, but also had potential implications on their male counterparts. We sought to determine the association of Dobbs with the number and characteristics of men seeking vasectomy. METHODS A retrospective review was performed to determine the number of vasectomy consults and procedures completed at a single Michigan health system in the 6 months following Dobbs (June 24, 2022-December 24, 2022) vs the same 6-month time frame between 2019 and 2021. Another retrospective review was conducted in the 3 months following Dobbs (June 24, 2022-September 24, 2022) vs the same days in 2021 to determine the number of vasectomy consults completed and to evaluate for differences in the characteristics of these men. RESULTS In the 6 months after Dobbs, there was a 150% and 160% increase in vasectomy consults and procedures completed, respectively, compared to a similar time frame in 2019 to 2021. In the 3 months after Dobbs, there was a 225% increase in new vasectomy consults compared to a similar time frame in 2021. There were no differences in the age, race, religion, median household income, or insurance type of men seeking vasectomy consult pre- vs post-Dobbs. Partnerless men (odds ratio 3.66) and those without children (odds ratio 2.85) were more likely than married men and those with 3 or more children, respectively, to seek vasectomy consult post-Dobbs. CONCLUSIONS Dobbs was associated with a marked increase in vasectomy consultations and procedures at our institution in the state of Michigan. Future studies are needed to determine the long-term implications of Dobbs on vasectomy practices and determine if vasectomy practices differ by states and their respective abortion laws.

Abstract
BACKGROUND Patients with lymph node positive (pN+) disease found at the time of radical prostatectomy with pelvic lymphadenectomy for clinically localized prostate cancer (CaP) are at high risk of disease persistence and progression. Contemporary management trends of pN+ CaP are not well described. MATERIALS AND METHODS Patients in the Michigan Urologic Surgery Improvement Collaborative (MUSIC) with clinically localized prostate cancer who underwent radical prostatectomy between 2012 and 2023 with cN0/pN+ disease were identified. The primary outcome was to evaluate patient and practice-level factors associated with time to secondary post-RP treatment. Secondary outcomes included practice-level variation in management of pN+ CaP and rates of secondary treatment modality. To assess factors associated with secondary treatment, a Cox proportional hazards model of a 60-day landmark analysis was performed. RESULTS We identified 666 patients with pN+ disease. Overall, 66% underwent secondary treatment within 12 months post-RP. About 19% of patients with detectable post-RP PSA did not receive treatment. Of patients receiving secondary treatment after 60-days post-RP, 34% received androgen deprivation therapy (ADT) alone, 27% received radiation (RT) alone, 36% received combination, and 4% received other systemic therapies. In the multivariable model, pathologic grade group (GG)3 (HR 1.5; 95%CI: 1.05-2.14), GG4-5 (HR 1.65; 95%CI: 1.16-2.34), positive margins (HR 1.46; 95%CI: 1.13-1.88), and detectable postoperative PSA ≥0.1 ng/ml (HR 3.46; 95%CI: 2.61-4.59) were significantly associated with secondary post-RP treatment. There was wide variation in adjusted practice-level 12-month secondary treatment utilization (28%-79%). CONCLUSIONS The majority pN+ patients receive treatment within 12 months post-RP which was associated with high-risk pathological features and post-RP PSA. Variation in management of pN+ disease highlights the uncertainty regarding the optimal management. Understanding which patients will benefit from secondary treatment, and which type, will be critical to minimize variation in care.

Abstract
OBJECTIVE To examine the relationship between antisperm antibody (ASA), pregnancy rates, and method of conception following vasectomy reversal, given that before and after vasectomy reversal, patients wonder if ASAs will prevent them from achieving pregnancy and American Urological Association vasectomy guidelines call for additional research to answer this question. METHODS We performed retrospective chart review and phone interview of patients who underwent vasectomy reversal at our institution from 1/1/2000 to 12/31/2018. We excluded patients who underwent vasectomy reversal for pain, or without postoperative semen analysis with ASA. We categorized patients as having low (<50%) or high (≥50%) ASA levels using the first postoperative semen analysis. Our primary outcome was pregnancy rate, including method of conception. Differences in pregnancy rates were tested using Fisher exact test. RESULTS Two hundred and four patients were chart reviewed. Median age at time of surgery was 40years and median obstruction interval was 7.3years. Median partner age was 32years. One hundred sixty-four (80%) patients underwent bilateral vasovasostomy. Eighty-five patients (42%) had low (<50%) ASA levels and 119 (58%) had high (≥50%) ASA levels. Sixty-seven patients completed phone interviews. Of 27 men with low ASA levels, 19 (70%) achieved a pregnancy with 16 (59%) spontaneous pregnancy. Of 40 men with high ASA levels, 30 (75%) achieved a pregnancy with 16 (40%) spontaneous pregnancy. The Fisher exact test P-value was .2. CONCLUSION ASA levels are not associated with pregnancy rate or method of conception after vasectomy reversal. These findings can improve patient counseling before and after vasectomy reversal.

Abstract
INTRODUCTION Chronic scrotal pain is difficult to manage, and epididymectomy is a treatment option for a subset of men with pain localized to the epididymis. We sought to evaluate the efficacy of epididymectomy at our institution. METHODS Between 2000 and 2020, 225 men underwent epididymectomy at our institution for pain localized to the epididymis and not part of a greater constellation of pelvic pain or urinary symptoms. Our primary outcome measure was change in pain after epididymectomy, categorized as cured/improved or no change/worsened. Multivariable logistic regression compared the impact of pain duration, and surgical and psychiatric histories on postoperative pain. RESULTS Patients in both outcome categories-cured/improved and no change/worsened-were similar in age and BMI. Overall, 162 patients (72%) reported cured/improved pain at the last documented follow-up visit. Median follow-up time was 12 (IQR 1-364) weeks. About half of the cohort (n = 117, 52%) had a prior vasectomy, and there was no difference in outcome based on vasectomy history on multivariate analysis (OR 0.625, P = .3). Men with pain duration > 1 year (OR 0.46, P = .03), diagnosed psychiatric conditions (OR 0.44, P = .04), or prior scrotal/inguinal/abdominal surgeries other than vasectomy (OR 0.47, P = .03) had decreased odds of pain relief after epididymectomy. CONCLUSIONS This 20-year analysis is the largest review of postepididymectomy outcomes reported. Among carefully screened men, 72% had resolution or improvement of scrotal pain. Epididymectomy is most effective for men with < 1 year of focal epididymal pain, with no history of psychiatric conditions or scrotal/inguinal/abdominal surgery other than vasectomy.

Abstract
OBJECTIVE To determine if a discrepancy exists in the number and type of cases logged between female and male urology residents. MATERIALS AND METHODS ACGME case log data from 13 urology residency programs was collected from 2007 to 2020. The number and type of cases for each resident were recorded and correlated with resident gender and year of graduation. The median, 25th and 75th percentiles number of cases were calculated by gender, and then compared between female and male residents using Wilcoxon rank sum test. RESULTS A total of 473 residents were included in the study, 100 (21%) were female. Female residents completed significantly fewer cases, 2174, compared to male residents, 2273 (P = .038). Analysis by case type revealed male residents completed significantly more general urology (526 vs 571, P = .011) and oncology cases (261 vs 280, P = .026). Additionally, female residents had a 1.3-fold increased odds of logging a case in the assistant role than male residents (95% confidence interval: 1.27-1.34, P < .001). CONCLUSION Gender-based disparity exists within the urology training of female and male residents. Male residents logged nearly 100 more cases than female residents over 4years, with significant differences in certain case subtypes and resident roles. The ACGME works to provide an equal training environment for all residents. Addressing this finding within individual training programs is critical.

Abstract
INTRODUCTION Onabotulinumtoxin A (BTX-A) is a well-established treatment for overactive bladder (OAB). The American Urological Association (AUA) 2008 Antibiotic Best Practice Statement (BPS) recommended trimethoprim-sulfamethoxazole or fluoroquinolone for cystoscopy with manipulation. The aim of the study was to evaluate concordance with antibiotic best practices at the time of BTX-A injection and urinary tract infection (UTI) rates based on antibiotic regimen. METHODS Men and women undergoing first-time BTX-A injection for idiopathic OAB with 100 units in 2016, within the SUFU Research Network (SURN) multi-institutional retrospective database were included. Patients on suppressive antibiotics were excluded. The primary outcome was concordance of periprocedural antibiotic use with the AUA 2008 BPS antimicrobials of choice for "cystoscopy with manipulation." As a secondary outcome we compared the incidence of UTI among women within 30 days after BTX-A administration. Each outcome was further stratified by procedure setting (office vs. operating room; OR). RESULTS Of the cohort of 216 subjects (175 women, 41 men) undergoing BTX-A, 24 different periprocedural antibiotic regimens were utilized, and 98 (45%) underwent BTX-A injections in the OR setting while 118 (55%) underwent BTX-A injection in the office. Antibiotics were given to 86% of patients in the OR versus 77% in office, and 8.3% of subjects received BPS concordant antibiotics in the OR versus 82% in office. UTI rates did not vary significantly among the 141 subjects who received antibiotics and had 30-day follow-up (8% BPS-concordant vs. 16% BPS-discordant, CI -2.4% to 19%, p = 0.13). A sensitivity analysis of UTI rates based on procedure setting (office vs. OR) did not demonstrate any difference in UTI rates (p = 0.14). CONCLUSIONS This retrospective multi-institutional study demonstrates that antibiotic regimens and adherence to the 2008 AUA BPS were highly variable among providers with lower rates of BPS concordant antibiotic use in the OR setting. UTI rates at 30 days following BTX-A did not vary significantly based on concordance with the BPS or procedure setting.

Abstract
Introduction: The aim of our study was to investigate the impact of diabetes-related factors on the dental disease outcomes of diabetes patients in Trincomalee, Sri Lanka. Materials and Methods: Dental data were collected from 80 type-2-diabetic individuals. A dental risk score was calculated based on the frequency of dental outcomes observed and categorized as low risk (≤3 dental outcomes) and high risk (>3 dental outcomes). Results: In this cohort of men and women with type 2 diabetes, there was a high frequency of periodontal related outcomes, including missing teeth (70%), gingival recessions (40%), tooth mobility (41%), and bleeding (20%). Thirty-nine (39%) of participants had high dental risk, while forty-nine (61%) had low risk. Conclusions: After controlling for age, participants with higher capillary blood glucose levels had 3-fold greater odds of a high dental risk score (OR = 2.93, 95%CI = 1.13, 7.61). We found that poor glycemic control indicated by elevated capillary blood glucose was associated with increased dental risk.

Abstract
Multiple estimates have approximated a urologist shortage per capita of around 30% by 2030. In the context of the impending urologic workforce shortage, it is critical to have a nuanced understanding of the degree of workforce shortage in comparison with the US population to mitigate the negative downstream effects in the future. In continued growth and stagnant growth projection models, we found that female urologists make up a significant proportion of the workforce growth over the next four decades. This projection highlights the need for purposeful recruitment, structural changes, and advocacy among urology leadership to support and retain female urologists.

Abstract
Purpose The purpose of this study was to analyze the impact of prostate rectal spacers on sexual quality of life (QOL) following external beam radiation therapy (RT). Methods and materials Patient- reported QOL was evaluated using the Expanded Prostate Cancer Index Composite (EPIC). Patients were pooled from two sources: a randomized controlled trial and a non-randomized cohort of patients from a single institution. Both cohorts used the same spacing product and QOL instrument. Analysis was limited to those with good baseline pre-treatment sexual QOL (EPIC >/= 60). Differences in QOL summary score and individual items were assessed compared with baseline and between treatment arms. Results A total of 128 men had good baseline sexual function and were evaluated (64% with spacer and 36% without) with QOL data available for median 33 months (range: 2.5-69.4 months). Men without spacer were more likely to have declines in sexual function (p < 0.0001), bother (p = 0.0002), and sexual summary score (p < 0.0001). A minimally important difference of 10 points (1xMID) and 20 point (2xMID) was more likely without rectal spacer [10 points: odds ratio 3.53, (95% confidence interval 1.11-11.2), p = 0.032; 20 points: odds ratio 3.29, (95% confidence interval 1.16-9.33), p = 0.025]. Seven of 13 QOL items were statistically superior with hydrogel (six of nine functional and one of four bother), while no items were statistically superior for control. At baseline, more men treated with hydrogel had erections sufficient for intercourse; however, when analyzed only by the men with best baseline erectile potential and excluding those with worse function, the benefit of rectal spacing was maintained with a higher likelihood of preservation of erections sufficient for intercourse in those treated with hydrogel. Conclusion In this pooled analysis of QOL after prostate RT, the utilization of a hydrogel spacer was associated with better sexual QOL, less men with measurable declines in sexual QOL, and higher rates of adequate erectile function.

Abstract
INTRODUCTION Circumcision is a common procedure that can evoke caregiver anxiety in the postoperative period due to unfamiliarity with the healing process. To mitigate unnecessary healthcare utilization such as phone calls and unanticipated clinic or emergency department (ED) visits, photographic atlases have been developed to better prepare caregivers for the recovery process. The objective of our study is to further investigate the efficacy of a photographic atlas in its ability to decrease postoperative healthcare utilization using an increased sample size and extended study period compared to previous studies. MATERIALS AND METHODS In this study, we compared a prospective intervention cohort of patients undergoing circumcision at our institution who received a photographic atlas during postoperative teaching to a retrospective cohort of patients who had not received it. Our primary outcome was unanticipated healthcare utilization, defined as postoperative telephone calls and unanticipated presentations to the urology clinic or ED. RESULTS The retrospective no-atlas cohort included 105 patients, and the prospective intervention atlas cohort included 80 patients. Both groups were similar with respect to age (p = 0.47) and other demographics. There was no statistically significant difference in healthcare utilization between the no-atlas and atlas cohort. Specifically, we identified no difference in the number of phone calls to clinic staff (12 [11.4%] vs. 11 [13.8%], p = 0.64) or unanticipated postoperative clinic or ED visits (2 [1.9%] vs. 4 [5.0%], p = 0.41). DISCUSSION The use of a photographic atlas as part of caregiver support for circumcision patients did not demonstrate a statistically significant reduction in either postoperative phone calls or clinic/ED visits. The decrease in absolute number of caregiver phone calls was minimal (12-11), with a small increase in follow-up presentations (2-4). The lack of significant change may be due to the already infrequent occurrence of these events following circumcision, as demonstrated by the no-atlas cohort. Other potential advantages of the atlas, such as improved caregiver confidence and satisfaction, may have been present, but were not measured in this study. CONCLUSIONS Adding to the mixed results of previous studies, these findings do not support that photographic atlases decrease unanticipated healthcare utilization in children undergoing a circumcision. However, utilization was found to be low. Additionally, further studies are needed to determine other significant benefits of this form of education, such as improved caregiver confidence and satisfaction.

Abstract
INTRODUCTION Adolescent varicocele is a common urologic condition with a spectrum of outcomes, leading to variations in management. Testicular hypotrophy is a common indication for surgery Routine monitoring may be an appropriate form of management for many adolescents with testicular hypotrophy, as studies have shown that a large proportion of these patients may experience catch-up growth of the ipsilateral testis. Furthermore, there are few longitudinal studies which have correlated patient specific factors to catch-up growth. We aimed to determine the frequency of testicular catch up-growth in adolescents with varicocele while also examining if patient specific factors such as BMI, BMI percentile, or height correlated with testicular catch-up growth. METHODS A retrospective chart review found adolescent patients who presented to our institution with varicocele from 1997 to 2019. Patients between the ages of 9 and 20 years with left-sided varicocele, a clinically significant testicular size discrepancy, and at least two scrotal ultrasounds at least one year apart were included in analysis. Testicular size discrepancy of greater than 15% on scrotal ultrasound was considered clinically significant. Testicular size was estimated in volume (mL) via the Lambert formula. Statistical relationships between testicular volume differential and height, body mass index (BMI), and age were described with Spearman correlation coefficients (ρ). RESULTS 40 patients had a testicular volume differential of greater than 15% at some point during their clinical course and were managed non-operatively with observation and serial testicular ultrasounds. On follow-up ultrasound, 32/40 (80%) had a testicular volume differential of less than 15%, with a mean age of catch up growth at 15 years (SD 1.6, range 11-18 years). There were no significant correlations between baseline testicular volume differential and baseline BMI (ρ = 0.00, 95% CI [-0.32, 0.32]), baseline BMI percentile (ρ = 0.03, 95% CI [-0.30, 0.34]), or change in height over time (ρ = 0.05, 95% CI [-0.36, 0.44]). DISCUSSION The majority of adolescents with varicocele and testicular hypotrophy exhibited catch-up growth with observation, suggesting that surveillance is an appropriate form of management in many adolescents. These findings are consistent with previous studies and further indicate the importance of observation for the adolescent varicocele. Further research is warranted to determine patient specific factors that correlate with testicular volume differential and catch up growth in the adolescent varicocele.

Abstract
Background An increasing number of gender diverse individuals are presenting for gender affirming care. An option for genital gender affirming surgery (gGAS) in transmasculine individuals is metoidioplasty, creating a small neophallus from enlarged clitoral tissue following prolonged testosterone exposure. The goal of this study is to understand factors which contribute to greater exposed neophallus length following metoidioplasty. Methods We performed a retrospective chart review on patients presenting to a single academic institution who underwent a metoidioplasty. All operations were performed using the Belgrade technique with or without urethral lengthening depending on patient preference. Results Twenty-seven patients underwent metoidioplasty from 2017-2022. Sixteen had recorded stretched clitoral length (pre-operatively) and exposed neophallus length (post-operatively). The median length of time on testosterone therapy was 4.6 years. The median stretched clitoral length was 5.8 cm, and exposed neophallus length was 6 cm. There was a strong correlation between pre-operative length and post-operative length (ρ=0.9; P<0.0001). There were no correlations between pre-operative length or exposed neophallus length and BMI (ρ=-0.02, P=0.93; ρ=0.05, P=0.83, respectively). Time on testosterone does not correlate with stretched clitoral length nor exposed neophallus length (ρ=-0.28, P=0.15; ρ=-0.35, P=0.18, respectively). Conclusions Patients considering metoidioplasty often wonder how large their neophallus will be. We found that patients can expect exposed neophallus length to be about 0.6 cm longer than their pre-operative stretched clitoral length. No evidence of association of time on testosterone nor BMI with exposed neophallus length was found. This information is crucial for gender diverse patients to make informed decisions about gGAS.

Abstract
PURPOSE AUA stone management guidelines recommend stenting duration following ureteroscopy be minimized to reduce morbidity; stents with extraction strings may be used for this purpose. However, an animal study demonstrated that short dwell time results in suboptimal ureteral dilation, and a pilot clinical study showed this increases postprocedure events. Using real-world practice data we examined stent dwell time after ureteroscopy and its association with postoperative emergency department visits. MATERIALS AND METHODS We used the Michigan Urological Surgery Improvement Collaborative registry to identify ureteroscopy and stenting procedures (2016-2019). Pre-stented cases were excluded. Stenting cohorts with and without strings were analyzed. Using multivariable logistic regression we evaluated the risk of an emergency department visit occurring on the day of, or day after, stent removal based on dwell time and string status. RESULTS We identified 4,437 procedures; 1,690 (38%) had a string. Median dwell time was lower in patients with a string (5 vs 9 days). Ureteroscopy in younger patients, smaller stones, or renal stone location had a higher frequency of string use. The predicted probability of an emergency department visit was significantly greater in procedures with string, compared to without string, when dwell times were less than 5 days (P < .01) but were not statistically significant after. CONCLUSIONS Patients who had ureteroscopy and stenting with a string have short dwell times. Patients are at increased risk of a postoperative emergency department visit around the time of stent removal if dwell time is ≤4 days. We recommended stenting duration of at least 5 days in nonpre-stented patients.

Abstract
BACKGROUND Studies assessing the stone-free rate (SFR) after ureteroscopy are limited to expert centers with varied definitions of stone free. Real-world data including community practices related to surgeon characteristics and outcomes are lacking. OBJECTIVE To evaluate the SFR for ureteroscopy and its predictors across diverse surgeons in Michigan. DESIGN, SETTING, AND PARTICIPANTS We assessed the Michigan Urological Surgery Improvement Collaborative (MUSIC) clinical registry for patients with renal or ureteral stones treated with ureteroscopy between 2016 and 2021 who had postoperative imaging. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Stone free was defined as no fragments on imaging reports within 60 d entered by independent data abstractors. Factors associated with being stone free were examined using logistic regression, including annual surgeon volume. We then assessed variation in surgeon-level SFRs adjusted for risk factors. RESULTS AND LIMITATIONS We identified 6487 ureteroscopies from 164 surgeons who treated 2091 (32.2%) renal and 4396 (67.8%) ureteral stones. The overall SFRs were 49.6% (renal) and 72.7% (ureteral). Increasing stone size, lower pole, proximal ureteral location, and multiplicity were associated with not being stone free. Female gender, positive urine culture, use of ureteral access sheath, and postoperative stenting were associated with residual fragments when treating ureteral stones. Adjusted surgeon-level SFRs varied for renal (26.1-72.4%; p < 0.001) and ureteral stones (52.2-90.2%; p < 0.001). Surgeon volume was not a predictor of being stone free for renal stones. Limitations include the lack of imaging in all patients and use of different imaging modalities. CONCLUSIONS The real-world complete SFR after ureteroscopy is suboptimal with substantial surgeon-level variation. Interventions focused on surgical technique refinement are needed to improve outcomes for patients undergoing ureteroscopy and stone intervention. PATIENT SUMMARY Results from a diverse group of community practicing and academic center urologists show that for a large number of patients, it is not possible to be completely stone free after ureteroscopy. There is substantial variation in surgeon outcomes. Quality improvement efforts are needed to address this.

Abstract
OBJECTIVE To develop and validate a model to predict whether patients undergoing ureteroscopy (URS) will receive a stent. METHODS Using registry data obtained from the Michigan Urological Surgery Improvement Collaborative Reducing Operative Complications from Kidney Stones initiative, we identified patients undergoing URS from 2016 to 2020. We used patients' age, sex, body mass index, size and location of the largest stone, current stent in place, history of any kidney stone procedure, procedure type, and acuity to fit a multivariable logistic regression model to a derivation cohort consisting of a random two-thirds of episodes. Model discrimination and calibration were evaluated in the validation cohort. A sensitivity analysis examined urologist variation using generalized mixed-effect models. RESULTS We identified 15,048 URS procedures, of which 11,471 (76%) had ureteral stents placed. Older age, male sex, larger stone size, the largest stone being in the ureteropelvic junction, no prior stone surgery, no stent in place, a planned procedure type of laser lithotripsy, and urgent procedure were associated with a higher risk of stent placement. The model achieved an area under the receiver operating characteristic curve of 0.69 (95% CI 0.67, 0.71). Incorporating urologist-level variation improved the area under the receiver operating characteristic curve to 0.83 (95% CI 0.82, 0.84). CONCLUSION Using a large clinical registry, we developed a multivariable regression model to predict ureteral stent placement following URS. Though well-calibrated, the model had modest discrimination due to heterogeneity in practice patterns in stent placement across urologists.

Abstract
PURPOSE The ROCKS (Reducing Operative Complications from Kidney Stones) program in MUSIC (Michigan Urological Surgery Improvement Collaborative) was created to optimize ureteroscopy outcomes. Through data collection, distribution of reports, patient education, and standardization of medication, post-ureteroscopy emergency department visits in Michigan have declined. It is unclear whether this is because of statewide quality efforts or due to national trends. We therefore sought to understand emergency department visit rates in Michigan compared to a national data set. MATERIALS AND METHODS We compared the MUSIC ROCKS clinical registry in Michigan against a national cohort, Optum's de-identified Clinformatics Data Mart, from 2016-2021 (excluding Michigan). We identified patients who underwent ureteroscopy and the proportion who had a postoperative emergency department visit within 30 days. Emergency department rates were modeled over time, adjusting for age, gender, comorbidity, and ureteral stenting. RESULTS We identified 24,688 patients in MUSIC ROCKS and 99,340 in the Clinformatics Data Mart database who underwent ureteroscopy. The risk-adjusted emergency department visit rate in MUSIC ROCKS significantly declined over the study period (10.5% in 2016 to 6.9% in 2021, P < 0.001) while the mean emergency department visit rate in the Clinformatics Data Mart cohort was 9.9% and did not change over time (9.6% in 2016 to 10% in 2021). Comparing emergency department visits between the cohorts, the MUSIC ROCKS rate significantly declined relative to the Clinformatics Data Mart (P < 0.001) over the study period. CONCLUSIONS Postoperative emergency department visit rates in Michigan have declined significantly after ureteroscopy since the establishment of MUSIC ROCKS. This decline outpaced national rates, providing evidence that systematic quality initiatives can improve urological care.

Abstract
OBJECTIVES The long-term goal of this study is to investigate the efficacy of a novel, ultrasound-based technique called subharmonic-aided pressure estimation (SHAPE) to measure bladder pressure as a part of a cystometrogram (CMG) in a urodynamic test (ie, pressure-flow study). SHAPE is based on the principle that subharmonic emissions from ultrasound contrast microbubbles (MBs) decrease linearly with an increase in ambient pressure. We hypothesize that, using the SHAPE technique, we can measure voiding bladder pressure catheter-free. This is of importance because the CMG catheter, due to its space-occupying property and non-physiological effects, can undermine the reliability of the test during voiding and cause misdiagnosis. In this study, we tested this hypothesis and optimized the protocol in a controlled benchtop environment. MATERIALS AND METHODS A bladder phantom was designed and built, capable of simulating clinically relevant bladder pressures. Laboratory-made lipid-shelled MBs (similar in composition to the commercial agent, DEFINITY) was diluted in 0.9% normal saline and infused into the bladder phantom using the CMG infusion system. A typical simulated CMG consists of 1 filling and 4 post-filling events. During CMG events, the bladder phantom is pressurized multiple times at different clinically relevant levels (small, medium, and large) to simulate bladder pressures. Simultaneous with pressurization, MB subharmonic signal was acquired. For each event, the change in MB subharmonic amplitude was correlated linearly with the change in bladder phantom pressure, and the SHAPE conversion factor (slope of the linear fit) was determined. In doing so, a specific signal processing technique (based on a small temporal window) was used to account for time-decay of MB subharmonic signal during a simulated CMG. RESULTS A strong inverse linear relationship was found to exist between SHAPE and bladder phantom pressures for each of the CMG filling and post-filling events ( r2> 0.9, root mean square error < 0.3 dB, standard error <0.01 dB, and P < 0.001). SHAPE showed a transient behavior in measuring bladder phantom pressure. The SHAPE conversion factor (in dB/cm H 2 O) varied between filling and post-filling events, as well as by post-filling time. The magnitude of the SHAPE conversion factor tended to increase immediately after filling and then decreases with time. CONCLUSIONS Microbubble subharmonic emission is an excellent indicator of bladder phantom pressure variation. The strong correlation between SHAPE signal and bladder phantom pressure is indicative of the applicability of this method in measuring bladder pressure during a CMG. Our results suggest that different SHAPE conversion factors may be needed for different events during a CMG (ie, at different time points of a CMG). These findings will help us better protocolize this method for introduction into human subjects and allow us to take the next step toward developing a catheter-free voiding CMG using SHAPE.

Abstract
PURPOSE To optimize recovery after radical cystectomy (RC), providers stress the importance of ambulation and adequate rest. However, little is known about the activity and sleep habits of patients undergoing RC. Therefore, we utilized a wearable physical activity monitor (PAM) in the perioperative period to provide the first objective data on physical activity and sleep habits for RC patients. MATERIALS AND METHODS We prospectively identified patients ≥60 years old with planned RC. Participants completed a 4-week prehabilitation exercise program prior to surgery. They wore a PAM for 7-day intervals: at baseline, after prehabilitation, at postoperative day (POD) 30 and POD90. We tracked physical activity via metabolic equivalents (METs). METs were categorized by intensity: light (MET 1.5-<3), moderate (MET 3-<6), and vigorous (MET ≥6). We calculated daily step totals. We tracked hours slept and number of sleep awakenings. We correlated activity and sleep with self-reported quality of life (QOL). RESULTS Forty-two patients completed prehabilitation and RC. Moderate intensity exercise decreased at POD30 (61 minutes/d at baseline, 30 minutes/d at POD30, P = 0.005). Physical activity did not significantly differ for light or vigorous activity at any timepoint. RC did not significantly affect sleep. Sleep and physical activity were associated with mental and physical QOL, respectively. CONCLUSIONS This is the first study utilizing patient-worn monitors in RC to track physical activity and sleep. This study gives patients and providers a better understanding of postcystectomy recovery expectations. With these results in mind, interventions may be implemented to optimize activity and sleep in the perioperative period.

Abstract
345 Background: Decipher is a tissue-based genomic classifier (GC) developed and validated in the post-radical prostatectomy (RP) setting to help guide adjuvant treatment decisions for prostate cancer (PCa). We conducted the first prospective, randomized trial assessing the impact of GC testing on adjuvant therapy use. Here, we determine the impact of GC testing on patient reported (PRO) quality of life outcomes (QoL) in men at high-risk of post-RP recurrence. Methods: The G-MINOR trial is a prospective, unblinded, randomized trial which enrolled 356 patients from 12 centers in the Michigan Urological Surgery Improvement Collaborative (MUSIC). Patients were enrolled between Aug 2016-July 2018. Eligible patients had undergone RP within 9 months of enrollment, had pT3-4 disease and/or positive surgical margins, and a post-RP PSA <0.1ng/mL. Patients were assigned to either the GC or usual-care (UC) group using cluster-crossover block randomization assignments. Evaluable patients (338) were followed for at least 18 months. PROs were obtained using the Expanded Prostate Cancer Index Composite (EPIC-26) survey at baseline (before RP), 3, 6, 12, and 24 months after RP. Results: A total of 226/338 evaluable men (67%) had PRO data for this analysis (116 UC arm/110 GC arm). Median age was 65 years. Of the 226 men included in the PRO analysis, a total of 23 (9 UC arm/14 GC arm) had adjuvant treatment (p = 0.22). At 12 months follow-up, those in the GC arm had no significant change in adjusted mean difference in domain score from baseline compared to those in the UC arm for urinary irritative (UIR) function (1.0, 95% CI [-2.9– 4.9], p=0.6), urinary incontinence (UI) (0.8, 95% CI [-5.1– 6.7], p=0.8), or sexual function (SF) (0.5, 95% CI [-6.9– 7.9], p=0.9). This remained true at 24 months for all three domains [UIR; (2.3, 95% CI [-2.1– 6.6], p=0.3)], [UI; (-0.3, 95% CI [-7.3– 6.7], p=0.9)], [SF; (1.5, 95% CI [-6.8– 9.7], p=0.7)]. Conclusions: In the first ever randomized trial testing the clinical utility of a GC test in localized PCa, longitudinal patient reported QOL outcomes were not significantly different between men who underwent risk stratification with or without Decipher. Clinical trial information: NCT02783950 .

Abstract
OBJECTIVE To evaluate the association between work-life balance satisfaction for practicing urologists who have children <18 years compared to those who do not have children or have children ≥18 years. METHODS We evaluated the association between work-life balance satisfaction based on partner status, partner employment status, child status, primary responsible party for family, total work hours per week, and total vacation weeks per year using 2018 and 2019 American Urological Association (AUA) census data with post-stratification adjustment methods. RESULTS Of 663 respondents, 77 (9.0%) were female and 586 (91%) were male. Female urologists are more likely to have an employed partner (79.vs 48.9%, P <.001), more likely to have children <18 years (75.0 vs 41.7%, P <.0001), and less likely to have a partner as primary caretaker of family (26.5 vs 50.3%, P <.0001) compared to male urologists. Urologists with children <18 years reported lower work-life balance satisfaction than those without (OR 0.65, P = .035). For every 5 additional hours works per week, urologists reported lower work-life balance (OR 0.84, P <.001). However, there are no statistically significant associations between work-life balance satisfaction and gender, employment status of their partner, primary responsible party for family responsibilities, and total weeks of vacation per year. CONCLUSION According to recent AUA census data, having children <18 years is associated with lower work-life balance satisfaction. This highlights opportunities to support young parents, both male and female, in the workplace to prevent burnout and maximize well-being among urologists.

Abstract
Introduction and Objective: Shared decision making is recommended to guide medical/surgical treatment strategies. We aimed at developing a surgical decision aid (SDA) facilitating decision making between ureteroscopy (URS) or shockwave lithotripsy (SWL) in patients with symptomatic nephrolithiasis. Methods: The SDA scope was identified through discussions with patients and urologists in the Michigan Urological Surgery Improvement Collaborative (MUSIC). A steering committee of patient advocates, MUSIC coordinating center, content experts, biostatisticians, and urologists was formed. Content domains were assessed through best available evidence and content experts. For content validation we anonymously surveyed 35 MUSIC urologists. Content validity ratios (CVR), numeric value indicating degree of expert validity, were calculated. Face validation interviews were conducted with patient advocates. Results: The SDA prototype using descriptive plain language and pictorial information was designed for nephrolithiasis patients, candidates for SWL or URS. It first provides patients procedural education whereas the second section informs urologists of patient goals. Six content domains were chosen: anesthesia type, effectiveness, number of procedures, risk, pain, and recovery. Overall, 91.4% and 85.7% of MUSIC urologists indicated that each section accomplished their goals, respectively. Anesthesia received an unacceptable CVR. High levels of face validation overall were reported with unacceptable scoring for anesthesia and recovery. Conclusions: We developed an SDA facilitating treatment choice between SWL and URS with promising content and face validity. Agreement and contradiction between anesthesia type and recovery validation results indicate the importance of shared decision making and the need for a validated SDA. Future work should focus on the SDAs value and opportunities for refinement in practice.

Abstract
PURPOSE Men with locally advanced prostate cancer who undergo radical prostatectomy (RP) often develop recurrence and require postoperative radiotherapy. We aimed to determine the safety of neoadjuvant stereotactic body radiotherapy (SBRT) before RP in this population. METHODS AND PATIENTS A single-institution phase 1 trial (NCT02946008) of men with high-risk or node-positive prostate cancer were enrolled between March and October 2017. The primary endpoint was to determine the maximum tolerated dose of SBRT based on a composite 30-day post-RP toxicity goal of ≤28% of patients experiencing a dose-limiting toxicity (DLT). Secondary outcomes included toxicity, efficacy, and multiple quality of life (QoL) inventories. SBRT (30-35 Gy/5 fractions) was delivered to the prostate and seminal vesicles, and 25 Gy/5 fractions to the pelvic lymph nodes. RP was performed for a median of 6 weeks post-SBRT. Hormone therapy was not allowed. RESULTS Median follow-up was 40 months (range, 33-44). Twenty-five percent of the patients (n = 4) experienced a DLT within 30 days post-RP; however, the trial was stopped early (n = 16 of planned 38 patients) owing to the proportion and severity of the late adverse events. Post-RP grade 3 genitourinary and gastrointestinal toxicities occurred in 75% (n = 12) and 25% (n = 4) of patients, respectively. Two patients required cystectomy and urinary diversion ≥2 years post-RP. At 24 months post-RP, 75% (n = 12) of men used ≥1 pad/d and 0% had erections suitable for intercourse. Surgical margins were negative in all patients and 31% (n = 5) had complete or partial (pre-RP) MRI-response to SBRT. Three-year biochemical recurrence and distant metastasis were 45% (95% CI, 5%-68%) and 28% (95% CI, 0%-49%), respectively. CONCLUSIONS Neoadjuvant SBRT followed by RP resulted in unacceptably high toxicity and severe QoL declines.

Abstract
PURPOSE Urgent indications for nephrolithiasis treatment include obstruction with intractable pain or renal impairment without untreated infection. Patients and hospitals may benefit from urgent primary ureteroscopy. We aimed to examine variation in urgent ureteroscopy utilization and associated outcomes. METHODS Using Reducing Operative Complications from Kidney Stones (ROCKS), we identified all ureteroscopy's between 2016 and 2019. Cases were classified by acuity (elective versus urgent). We assessed practice/urologist variation in urgent ureteroscopy performance. We characterized patients demographic, operative and outcomes data, making bivariate comparisons with elective ureteroscopy to understand implications of urgent surgery. We performed multilevel modeling to understand factors associated with unplanned healthcare encounters after urgent ureteroscopy. RESULTS 12,859 cases were identified from 33 practices and 204 urologists, 10,854 (84.4%) elective and 2005 (15.6%) urgent. Urgent ureteroscopy was performed on younger patients (53 vs 57, p < 0.001), with higher rates of ureteral stones (72.8% vs 56.8%, p < 0.001). Urgent ureteroscopy rates varied widely by practice (2-70%) and urologist (0-98%). Urgent ureteroscopy had higher stenting rates (77.4% vs 72.5%, p < 0.001), stone free rates (66% vs 58.4%, p < 0.001), and postoperative ED visits (11% vs 7.2%, p < 0.001). There were no differences in intraoperative complications or unplanned hospitalizations. Factors predictive of ED visits in urgent ureteroscopy included concomitant ureteral/renal stone location (OR = 1.53, CI = 1.05-2.23, p = 0.035). CONCLUSIONS In Michigan elective ureteroscopy is performed 5 times more frequently than urgent ureteroscopy with wide variation. Urgent ureteroscopy demonstrated low morbidity. Urgent ureteroscopy produced modestly higher stone free rates with a slightly increased frequency of unscheduled ED visits particularly for ureteral stones.

Abstract
Background There is a paucity of data on the clinical experience of priapism. Moreover, little work has explored differences in practice patterns between urologists and emergency medicine (EM) physicians. Our primary objective was to understand the priapism patient population and identify targets that may guide clinical translational efforts. Methods A retrospective chart review was performed on two priapism datasets from June 2008-July 2018-one focused on patients managed by urology and another on patients managed exclusively by EM physicians. Primary areas of interest included the duration of priapism and acute interventions during the consultation. Time to presentation, prior interventions and evaluation was also documented. Results Over the course of 10 years, there were 396 encounters for priapism in 95 unique patients. Urology was consulted 199 times in 83 unique patients and EM physicians managed 197 encounters in 15 unique patients. In the urology cohort, median duration of priapism was 6 hours, and 72% of patients required further intervention. For the EM cohort, median duration of priapism was 4 hours and 89% of patients required further intervention. Amongst all patients, nine patients presented 4 or more times for a total of 294 encounters. Conclusions Urology and EM managed a similar number of encounters, but EM patients had a shorter duration of priapism. Understanding the role of the EM physician and the urologist can help tailor joint curriculum efforts for initial priapism management while focusing on more complex management for urology trainees. A small proportion of patients accounted for the majority of visits secondary to recurrent ischemic priapism indicating a need to target prevention of these episodes on an outpatient basis.

Abstract
OBJECTIVE To understand how patient, practice/urologist-level factors impact imaging after ureteroscopy (URS) and shockwave lithotripsy (SWL). METHODS Using the Reducing Operative Complications from Kidney Stones (ROCKS) clinical registry from the Michigan Urological Surgery Improvement Collaborative (MUSIC), we identified patients undergoing URS and SWL between 2016-2019. Frequency and modality of 60-day postoperative imaging was assessed. We made bivariate comparisons across demographic/clinical data and assessed provider/practice-level imaging rate variation. We assessed correlation between imaging use within practices by treatment modality. Multivariable logistic regression controlling for practice/urologist variation was used to adjust for group differences. RESULTS 14,894 cases were identified (9621 URS, 5273 SWL) from 33 practices and 205 urologists. Overall postoperative imaging rate was 49.1% and was significantly different following URS and SWL (36.3% vs 72.4%,p<0.01). Substantial practice variation was seen in rates following URS (range 0-93.1%) and SWL (range 36-95.2%). Odds of postoperative imaging by practice varied significantly (range 0.02-1.96). Moderate postoperative imaging correlation for URS and SWL (0.7,p<0.001) was seen. No practice had significantly higher odds of post-URS imaging. There was increased odds of postoperative imaging for SWL modality, larger stones and renal stones. CONCLUSION Imaging rates after URS are almost half the rate for SWL with wide variation, underscoring uncertainty with how postoperative imaging is approached. However, practices who have higher post-URS imaging rates also image highly after SWL. Increased patient complexity and renal stone location drive imaging following URS.

Abstract
5018 Background: The PARP-inhibitor olaparib is approved for mCRPC patients (pts) with deleterious germline or somatic homologous recombination repair gene mutations (HRRm). PARP1 interacts with androgen signaling, and castration-resistant tumor cells exhibit increased PARP1 activity. Preclinically PARP1-inhibition synergizes with androgen receptor (AR) targeted therapy. BRCAAway is a biomarker selected, randomized, open-label, multicenter phase 2 trial evaluating efficacy of targeting AR vs PARP vs combination in first line mCRPC patients with germline and/or somatic HRRm in BRCA1, BRCA2, or ATM. Methods: Eligible mCRPC pts underwent tumor next generation sequencing and germline testing. Pts with inactivating BRCA1, BRCA2 and/or ATM alterations were randomized 1:1:1 to Arm 1 abiraterone (1000 mg daily) + prednisone (5mg bid) (Abi/pred), Arm 2 olaparib (300 mg bid) or Arm 3 olaparib + Abi/pred. The primary end point is progression-free survival (PFS) analyzed using Kaplan-Meier estimates and Cox regression. Secondary endpoints include measurable disease response rate (RR) by RECIST, PSA-RR, undetectable PSA (≤ 0.2 ng/ml) and toxicity. Arms 1 and 2 pts were allowed to cross over at progression. Pts with other HRRm were treated with olaparib; Arm 4 (ongoing). Results: 161 pts were registered and had NGS testing; 60 pts were randomized to Arms 1-3; to date 59 are evaluable for toxicity and 53 are evaluable for PFS. Baseline median age 67 (range 42-85) years; 54 pts were White, 6 were Black; sites of disease: bone only (n=31), soft tissue only (n=18), bone and soft tissue (n=10); median PSA 14.61 ng/ml (range 0.15-4036.8). Mutational status: BRCA1 only n = 2, BRCA2 only n = 39, ATM only n = 8, and > 1 HRRm n = 11. 34 pts had germline and 26 had somatic mutations. Median (range) follow-up time: 8.3 (0.8, 33.3), 12.2 (2.7, 21.8) and 16.8 (2.9, 41.7) months in Arms 1, 2 and 3. 43 pts had treatment-related adverse events; most common were fatigue (23 pts; 1 Grade (G) 3, 22 G1/2), nausea (17 pts, G1/2), and anemia (9 pts, 2 G3, 7 G1/2). ≥50% PSA decline was 79%, 67%, and 85% of pts in Arms 1, 2, and 3, respectively. Median PSA nadir (ng/mL) (95% CI) Arms 1-3: 2.17 (0.44, 49.27), 3.10 (0.83, 12.01), and 0.50 (0.10, 2.13), respectively. Undetectable PSA, median PFS, and 12-month PFS by Arm are listed in the table. Conclusions: In mCRPC pts with inactivating BRCA1, BRCA2 and/or ATM alterations Abi/pred + olaparib was well tolerated and resulted in longer PFS and better PSA response vs either agent alone. Clinical trial information: NCT03012321. [Table: see text]

Abstract
BACKGROUND Despite significant sexual dysfunction and distress after localized prostate cancer treatment, patients typically receive only physiologic erectile dysfunction management. The authors performed a randomized controlled trial of an online intervention supporting couples' posttreatment recovery of sexual intimacy. METHODS Patients treated with surgery, radiation, or combined radiation and androgen deprivation therapy who had partners were recruited and randomized to an online intervention or a control group. The intervention, tailored to treatment type and sexual orientation, comprised 6 modules addressing expectations for sexual and emotional sequelae of treatment, rehabilitation, and guidance toward sexual intimacy recovery. Couples, recruited from 6 sites nationally, completed validated measures at the baseline and 3 and 6 months after treatment. Primary outcome group differences were assessed with t tests for individual outcomes. RESULTS Among 142 randomized couples, 105 patients (mostly surgery) and 87 partners completed the 6-month survey; this reflected challenges with recruitment and attrition. There were no differences between the intervention and control arms in Patient-Reported Outcomes Measurement Information System Global Satisfaction With Sex Life scores 6 months after treatment (the primary outcome). Three months after treatment, intervention patients and partners reported more engagement in penetrative and nonpenetrative sexual activities than controls. More than 73% of the intervention participants reported high or moderate satisfaction with module content; more than 85% would recommend the intervention to other couples. CONCLUSIONS Online psychosexual support for couples can help couples to connect and experience sexual pleasure early after treatment despite patients' sexual dysfunction. Participants' high endorsement of the intervention reflects the importance of sexual health support to couples after prostate cancer treatment. LAY SUMMARY This study tested a web-based program supporting couples' sexual recovery of sexual intimacy after prostate cancer treatment. One hundred forty-two couples were recruited and randomly assigned to the program (n = 60) or to a control group (n = 82). The program did not result in improvements in participants' satisfaction with their sex life 6 months after treatment, but couples in the intervention group engaged in sexual activity sooner after treatment than couples in the control group. Couples evaluated the program positively and would recommend it to others facing prostate cancer treatment.

Abstract
OBJECTIVE Gender disparities have demonstrated influence on several areas of medical trainee academic performance and surgeon professional attainment. The impact of gender on perceived operative autonomy and performance of urology residents is not well understood. This single-institution pilot study explores this relationship by evaluating urology faculty and resident assessment of resident operative autonomy and performance using the Society for Improving Medical Professional Learning app. DESIGN Using Society for Improving Medical Professional Learning, trainees in a single urology residency program were assessed in operative cases on three scales (autonomy, performance, and case complexity). Intraoperative assessments were completed by both faculty and residents (self-evaluation). Respective evaluations were compared to explore differences in ratings by gender. SETTING University of Michigan Health, Ann Arbor, MI. PARTICIPANTS University of Michigan Urology Residents and Faculty. RESULTS A total of 516 evaluations were submitted from 18 urology residents and 20 urology faculty. Self-reported ratings among female and male residents did not differ significantly for autonomy (p = 0.20) or performance (p = 0.82). Female and male residents received overall similar autonomy ratings that were not significantly different from female faculty (p = 0.66) and male faculty (p = 0.81). For female residents, there was no significant difference in performance ratings by faculty gender (p = 0.20). This finding was consistent when the resident was male (p = 0.70). CONCLUSIONS At our institution, there is no overall gender-based difference in self-rated or faculty-rated operative autonomy or performance among urology trainees. Understanding relevant facets of institutional culture as well as educational strategies between faculty and residents may identify factors contributing to this outcome.

Abstract
502 Background: Anti-PD/PDL1 immune checkpoint inhibitor monotherapy is standard in select PDL1 expressing advanced urothelial cancer (aUC) and platinum-refractory aUC. Nab-paclitaxel (NAB) previously showed encouraging activity in platinum-refractory aUC. We conducted a single-arm trial of the combination of NAB and pembrolizumab in platinum-refractory or cisplatin-ineligible aUC. Methods: Eligible patients (pts) had RECIST 1.1 measurable urothelial cancer, grade ≤1 neuropathy, and ECOG PS 0-2. Study therapy consisted of NAB at starting dose of 125 mg/m2 IV on days 1 and 8 and pembrolizumab 200 mg IV on day 1 in 21-day cycles until progression, intolerable toxicity, death, or consent withdrawal. Continuing NAB after 6 cycles was optional. NAB starting dose was reduced to 100 mg/m2 after planned interim analysis on the first 17 subjects. Primary endpoint was overall response rate (ORR) by RECIST 1.1. Secondary endpoints included safety/toxicity, progression free survival (PFS), overall survival, complete response proportion, duration of response (DOR), and duration of therapy (DOT). Results: Between 2/2018 and 4/2021, 36 response evaluable pts were enrolled; 11 of upper tract origin, 32 men, mean age 71.5 years (range 52 – 88), 25 pure urothelial, 15 platinum-refractory, 21 cisplatin-ineligible by Galsky criteria, and ECOG PS was 0, 1 or 2 in 9, 20, and 7 pts, respectively. Unconfirmed best ORR was 58.3% (95% CI: 42-74) including 3 CR and 18 PR, confirmed ORR 50% (18/36); 31/36 pts experienced some tumor shrinkage. Median DOR was 19 weeks (95% CI: 15.6-34.8), and median PFS 5.4 months (95% CI: 4.6-7.9). Pts received a median of 6 cycles (range 1-14) with median DOT 4.2 months (range 0.6-9.6). Grade ≥3 adverse events (AE) occurred in 25 pts including fatigue (n = 6), anemia (n = 6), peripheral neuropathy (n = 3), and oral mucositis (n = 3); 6 discontinued treatment due to AEs. Ten pts had immune mediated AEs including 1 with encephalitis. Archival tumor NGS revealed TMB ≥10 in 5/21 available. Conclusions: The combination of NAB and pembrolizumab exhibited promising activity in advanced urothelial cancer with no unexpected toxicity. Clinical trial information: NCT03240016.

Abstract
103 Background: Prostate cancer with CDK12 inactivation represents a distinct subtype in mCRPC, tumors are characterized by excessive tandem duplications, genomic instability, gene fusion-caused putative neoantigens and increased tumor T cell infiltration. Retrospective experiences with ICI in CDK12 inactivation CRPC pts reported PSA and radiographic responses. We conducted a prospective multi-site clinical trial of ipilimumab and nivolumab in CDK12 inactivation or mutated cancers. Herein, we report our findings in the completed cohort A of men with mCPRC. Methods: Eligible pts had mCRPC (ongoing androgen deprivation therapy with serum testosterone £ 50 ng/dL) and putative CDK12 inactivation of function aberrations on any commercial or institutional CLIA/CAP approved next generation sequencing assay. Archival tumor tissue was requested for correlative biomarker analysis. Pts received nivolumab 3 mg/kg IV and ipilimumab 1 mg/kg IV q3 weeks for up to 4 cycles, followed by maintenance nivolumab at 480 mg IV q4 weeks until disease progression, intolerable toxicity, or consent withdrawal. The primary endpoint was PSA response, defined as a greater than or equal to 50% decline in PSA from baseline. Secondary endpoints included safety/toxicity, secondary efficacy measures including QoL and overall survival. Exploratory objectives included baseline tumor whole exome analysis and changes in circulating immune profiles with therapy. Results: As of data cut-off in Aug 2021, 28 mCRPC pts enrolled in Cohort A; median ECOG PS was 1 (0-2 range), 22/28 had Gleason 8-10 cancer, mean baseline PSA at study entry was 231 ng/dL, all pts had received ≥1 prior oral androgen signaling inhibitor and ≥1 cytotoxic chemotherapy. Unconfirmed PSA ≥30% decline was seen in 6/28 pts (21.4%) and PSA ≥50% decline in 4/28 pts (14.2%). Grade ≥3 possible/probable/definite adverse events were noted in 7/28 (25%) and SAEs in 10/28 pts (35.7%). Six pts (21.4%) experienced a rapid PSA increase by ≥ 10-fold over baseline. Conclusions: Combination immunotherapy was reasonably tolerated in this heavily pre-treated population and was associated with unconfirmed PSA responses in a subset of pts. Ongoing correlative analyses could explain responses mechanistically. Enrollment in Cohort B of non-prostate cancers and Cohort C of nivolumab monotherapy in prostate cancer are still ongoing. Clinical trial information: NCT03570619.

Abstract
INTRODUCTION Onabotulinumtoxin A (BTX-A) is an effective therapy for overactive bladder (OAB), however, adverse events may prevent patients from initiating therapy. The study objective was to report real-world rates of incomplete emptying and urinary tract infection (UTI) in men and women undergoing BTX-A for OAB. METHODS Eleven clinical sites performed a retrospective study of adults undergoing first-time BTX-A injection (100 units) for idiopathic OAB in 2016. Exclusions included: postvoid residual (PVR) > 150 ml, prior BTX-A, pelvic radiation, or need for preprocedure catheterization. Primary outcomes at 6 months were incomplete emptying (clean intermittent catheterization [CIC] or PVR ≥ 300 ml without the need for CIC); and UTI (symptoms with either positive culture or urinalysis or empiric treatment). We compared rates of incomplete emptying and UTI within and between sexes, using univariate and multivariable models. RESULTS 278 patients (48 men and 230 women) met inclusion criteria. Mean age was 65.5 years (range: 24-95). 35% of men and 17% of women had incomplete emptying. Men had 2.4 (95% CI: 1.04-5.49) higher odds of incomplete emptying than women. 17% of men and 23.5% of women had ≥1 UTI, the majority of which occurred within the first month following injection. The strongest predictor of UTI was a history of prior UTI (OR: 4.2 [95% CI: 1.7-10.3]). CONCLUSIONS In this multicenter retrospective study, rates of incomplete emptying and UTI were higher than many previously published studies. Men were at particular risk for incomplete emptying. Prior UTI was the primary risk factor for postprocedure UTI.

Abstract
Importance Projections to 2035 have demonstrated concern regarding a worsening urology workforce shortage. Objective To project the size and demographic characteristics of the urology workforce per capita into 2060 and to anticipate the timing and degree of the impending urology workforce shortage. Design, Setting, and Participants This population-based cross-sectional study used the 2019 American Urological Association Annual Census data and the Accreditation Council for Graduate Medical Education's Data Resource Book from 2007 to 2018. The cohort included practicing urologists in 2019. US Census data were used to approximate the projected US population. Data analysis was performed from June 2020 to March 2021. Exposures Continued growth stock and flow model of 13.8% and stagnant growth model of 0% increase of the incoming urology workforce with cohort projection per projected US population. Main Outcomes and Measures The primary outcome was urology workforce projection per the population aged 65 years and older. Urology workforce projections per capita and demographic characteristics of the urology workforce up to 2060 were calculated under guided assumptions with 2 stock and flow models. Results In 2019, there were 13 044 urologists (11 758 men [90.1.%]; 1286 women [9.9%]; median age range, 55-59 years), with 3.99 urologists per 100 000 persons and 311 new urologists entering the workforce. In a continued growth model, 2030 will have the lowest number of urologists per capita of 3.3 urologists per 100 000 persons, and recovery to baseline will occur by 2050. There are 23.8 urologists per 100 000 persons aged 65 years and older in 2020, which decreases to 15.8 urologists per 100 000 persons aged 65 years and older in 2035 and never recovers to its baseline level by 2060. In a stagnant growth model, there will be a continued decrease of urologists per capita to 3.1 urologists per 100 000 persons by 2060. There is a continued decrease in per capita urologists at each time point, with 13.1 urologists per 100 000 persons aged 65 years and older by 2060. Conclusions and Relevance With the impending urology workforce shortage, there will be an exaggerated shortage of total urologists per persons aged 65 years and older in both models. This projection highlights the need for structural changes and advocacy to maximize the available urology workforce.

Abstract
BACKGROUND In competitive residency specialties such as Urology, it has become increasingly challenging to differentiate similarly qualified applicants. Residency interviews are utilized to rank applicants, yet they are often biased and do not explicitly address ACGME core competencies. OBJECTIVE We hypothesized a team-based exercise in the urology residency interview centered on building LEGOs assesses core competences. DESIGN From 2014-2017, students interviewing for urology residency at two institutions participated in a LEGO™ building activity. Applicants were assigned to "architect"- describing how to construct a structure - or "builder" - constructing the same structure with pieces-using only verbal cues to assemble the structure. Participants were graded using a rubric assessing competencies of interpersonal communication, problem-based learning, professionalism, and manual dexterity (indicator of procedural skill). The total minimum score was 16 and maximum was 80. SETTING The study took place at two tertiary referral centers: University of Michigan Medical School in Ann Arbor, MI, and University of Utah School of Medicine in Salt Lake City, UT. PARTICIPANTS A total of 176 applicants participated, comprised of applicants interviewing for urology residency at two institutions during the study timeframe. RESULTS For architects and builders, there was a maximum score of 80, and minimum of 34 and 32, respectively. Both distributions show a right shift with mean scores of 64.3 and 65.9, and median scores of 69 and 65.5. Successful pairs excelled with consistent nomenclature and clear directionality. Ineffective pairs miscommunicated with false affirmations, inconsistent nomenclature, and lack of patience. CONCLUSIONS The LEGO™ exercise allowed for standardized assessment of applicants based on ACGME core competencies. The rubric identified poor performers who do not rise to the challenge of a team-based task.

Abstract
OBJECTIVE To assess the distribution of stone fragments (<0.25->2 mm) after in vitro dusting laser lithotripsy with varying pulse modes using canine calcium oxalate monohydrate (COM) stones. Recent work demonstrates that fragments <0.25 mm are ideal for dusting, and we hypothesized advanced pulse modes might improve this outcome. METHODS A 3D-printed bulb was used as a calyceal model containing a single COM stone. A 230-core fiber (Lumenis) was passed through a ureteroscope (LithoVue, Boston Scientific). Contact laser lithotripsy by a single operator was performed with dusting settings (0.5J x 30Hz; Moses Pulse120H) to deliver 1kJ of energy for each trial. Short pulse (SP), long pulse (LP), Moses Distance (MD) and Moses Contact (MC) modes were tested with 5 trials for each parameter. Primary outcome was mass of fragments <0.25, <0.5, <1, and <2 mm. Laser fiber tip degradation was measured using a digital caliper. RESULTS Mass of stone fragments <0.25 mm varied from 34.6%-43.0% depending on the pulse mode, with no statistically significant differences between modes. MC (98.5%) produced a greater mass of fragments <2 mm compared to LP (86.1%; P = .046) but not SP (92.0%). Significantly less fiber tip burnback occurred with MC (0.29 mm) and MD (0.28 mm), compared to SP (0.83 mm; P < .0005). CONCLUSION Regardless of pulse mode, greater than one-third of the mass of COM stone was reduced to fragments <0.25 mm following contact laser lithotripsy. MC produced a greater mass of fragments <2 mm compared to LP and demonstrated less fiber tip burnback compared to SP.

Abstract
Parathyroid hormone (PTH) is produced by the parathyroid glands in response to low serum calcium concentrations where it targets bones, kidneys, and indirectly, intestines. The N-terminus of PTH has been investigated for decades for its ability to stimulate bone formation when administered intermittently (iPTH) and is used clinically as an effective anabolic agent for the treatment of osteoporosis. Despite great interest in iPTH and its clinical use, the mechanisms of PTH action remain complicated and not fully defined. More than 70 gene targets in more than 90 murine models have been utilized to better understand PTH anabolic actions. Because murine studies utilized wild-type mice as positive controls, a variety of variables were analyzed to better understand the optimal conditions under which iPTH functions. The greatest responses to iPTH were in male mice, with treatment starting later than 12 weeks of age, a treatment duration lasting 5-6 weeks, and a PTH dose of 30-60 μg/kg/day. This comprehensive study also evaluated these genetic models relative to the bone formative actions with a primary focus on the trabecular compartment revealing trends in critical genes and gene families relevant for PTH anabolic actions. The summation of these data revealed the gene deletions with the greatest increase in trabecular bone volume in response to iPTH. These included PTH and 1-α-hydroxylase (Pth;1α(OH)ase, 62-fold), amphiregulin (Areg, 15.8-fold), and PTH related protein (Pthrp, 10.2-fold). The deletions with the greatest inhibition of the anabolic response include deletions of: proteoglycan 4 (Prg4, -9.7-fold), low-density lipoprotein receptor-related protein 6 (Lrp6, 1.3-fold), and low-density lipoprotein receptor-related protein 5 (Lrp5, -1.0-fold). Anabolic actions of iPTH were broadly affected via multiple and diverse genes. This data provides critical insight for future research and development, as well as application to human therapeutics. © 2021 The Authors.

Abstract
OBJECTIVES To evaluate patient factors associated with post-ureteroscopy opioid prescriptions, provider-level variation in opioid prescribing, and the relationship between opioid-free discharges and ED visits. METHODS This is a retrospective analysis of a prospective cohort study of adults age 18 years and older who underwent primary ureteroscopy for urinary stones from June 2016 to September 2019 within the Michigan Urological Surgery Improvement Collaborative (MUSIC) Reducing Operative Complications from Kidney Stones (ROCKS) quality improvement initiative. Postoperative opioid prescription trends and variation among practices and surgeons were examined. Multivariable logistic regression models defined risk factors for receipt of opioid prescriptions. The association among opioid prescriptions and postoperative ED visits within 30 days of surgery was assessed among complete case and propensity matched cohorts, matched on all measured characteristics other than opioid receipt. RESULTS 13,143 patients underwent ureteroscopy with 157 urologists across 28 practices. Post-ureteroscopy opioid prescriptions and ED visits declined (86% to 39%, P<.001; 10% to 6%, P<.001, respectively). Practice and surgeon-level opioid prescribing varied from 8% to 98%, and 0% to 98%, respectively. Patient-related factors associated with opioid receipt included male, younger age, and history of chronic pain. Procedure-related factors associated with opioid receipt included pre- and post-ureteroscopy ureteral stenting and access sheath use. An opioid-free discharge was not associated with increased odds of an ED visit (OR 0.77, 95% CI 0.62-0.95, P=.014). CONCLUSIONS There was no increase in ED utilization among those not prescribed an opioid after ureteroscopy, suggesting their routine use may not be necessary in this setting.

Abstract
OBJECTIVE To morphometrically measure to muscle mass which may reflect physical components of frailty. Hence, we evaluated the association between L4 total psoas area (TPA) and operative outcome after radical cystectomy (RC) for bladder cancer. METHODS In a retrospective single-center study, bladder cancer patients who underwent RC and urinary diversion between 2007 and 2012 were enrolled. TPA was evaluated in the cross-sectional imaging. The psoas muscles were normalized with the height. Male patients with a psoas mass index ≤7.4 cm2/m2 and female patients with a psoas mass index ≤5.2 cm2/m2 were classified as sarcopenic. Outcome measures were 30- and 90-day readmission and complications, and survival. Multivariable logistic and Cox proportional-hazards regression models were used to determine relevant predictors. RESULTS The median age of the 441 participants and follow up time was 68 years (IQR 59-75) and 1.2 years (IQR 0.5-1.9), respectively. One hundred forty-three patients (32.4%) were sarcopenic. The 30-day readmission and the complication rates were 13.8% and 44.7%, respectively. The 90-day readmission and complication rates were 23.9% and 53.1%, respectively. The 1-year mortality rate was 11.6% (95%CI 8.7-15.4). Multivariable logistic regression analysis revealed an association between increased TPA and lower odds of 30-day complications after RC (OR 0.95, 95%CI 0.92-0.99, P = .02); similarly, an increase in TPA was of prognostic value, although not statistically significant in the multivariable model (P = .05) once adjusting for other patient factors. CONCLUSION Sarcopenia predicted early complications and showed an informative trend for overall survival after RC, and thus may inform models predicting postsurgical outcomes.

Abstract
Murine models of tumor development often require invasive procedures for tumor implantation, potentially causing pain or distress. However, analgesics are often withheld during implantation because of concerns that they may adversely affect tumor development. Previous studies examining the effects of analgesics on the development and metastasis of various tumor lines show that the effect of analgesics depends on the tumor line and analgesic used. A blanket statement that analgesics affect the general growth of tumors is not adequate scientific justification for withholding pain relief, and pilot studies or references are recommended for each specific tumor cell line and treatment combination. In this study, we evaluated the effects of 2 commonly used analgesics on tumor growth in 2 models of prostate cancer (PCa) bone metastasis. We hypothesized that a one-time injection of analgesics at the time of intratibial injection of tumor cells would not significantly impact tumor growth. Either C57BL/6 or SCID mice were injected subcutaneously with an analgesic (carprofen [5 mg/kg], or buprenorphine [0.1 mg/kg]) or vehicle (0.1 mL of saline) at the time of intratibial injection with a PCa cell line (RM1 or PC3, n = 10 to 11 per group). Tumor growth (measured by determination of tumor burden and the extent of bone involvement) and welfare (measured by nociception, locomotion, and weight) were monitored for 2 to 4 wk. Neither carprofen or buprenorphine administration consistently affected tumor growth or indices of animal welfare as compared with the saline control for either cell line. This study adds to the growing body of literature demonstrating that analgesia can be compatible with scientific objectives, and that a decision to withhold analgesics must be scientifically justified and evaluated on a model-specific basis.

Abstract
PURPOSE Palbociclib, a cyclin-dependent kinase (CDK) 4/6 inhibitor, blocks proliferation in a RB and cyclin D-dependent manner in preclinical prostate cancer models. We hypothesized that cotargeting androgen receptor and cell cycle with palbociclib would improve outcomes in patients with metastatic hormone-sensitive prostate cancer (mHSPC). PATIENTS AND METHODS A total of 60 patients with RB-intact mHSPC were randomized (1:2) to Arm 1: androgen deprivation (AD) or Arm 2: AD + palbociclib. Primary endpoint was PSA response rate (RR) after 28 weeks of therapy. Secondary endpoints included safety, PSA, and clinical progression-free survival (PFS), as well as PSA and radiographic RR. Tumors underwent exome sequencing when available. Circulating tumor cells (CTC) were enumerated at various timepoints. RESULTS A total of 72 patients with mHSPC underwent metastatic disease biopsy and 64 had adequate tissue for RB assessment. A total of 62 of 64 (97%) retained RB expression. A total of 60 patients initiated therapy (Arm 1: 20; Arm 2: 40). Neutropenia was the most common grade 3/4 adverse event in Arm 2. Eighty percent of patients (Arm 1: 16/20, Arm 2: 32/40; P = 0.87) met primary PSA endpoint ≤4 ng/mL at 28 weeks. PSA undetectable rate at 28 weeks was 50% and 43% in Arms 1 and 2, respectively (P = 0.5). Radiographic RR was 89% in both arms. Twelve-month biochemical PFS was 69% and 74% in Arms 1 and 2, respectively (P = 0.72). TP53 and PIK3 pathway mutations, 8q gains, and pretreatment CTCs were associated with reduced PSA PFS. CONCLUSIONS Palbociclib did not impact outcome in RB-intact mHSPC. Pretreatment CTC, TP53 and PIK3 pathway mutations, and 8q gain were associated with poor outcome.

Abstract
OBJECTIVE To characterize the timing and effectiveness of medical management in resolving stent-dependent ureteral compression secondary to idiopathic retroperitoneal fibrosis (RPF), the long-term relevant outcomes, and the side effects of treatment. METHODS A retrospective review of RPF patients diagnosed from 2002-2018 was performed. Patients with hydronephrosis due to ureteral involvement that were managed with medication and with temporary stenting as needed, but without initial ureterolysis, were included. Patient demographics and RPF management details were obtained, including the following subsequent events: ureterolysis, nephrectomy, recurrent upper tract obstruction, and medication side effects. RESULTS Fifty-two patients met inclusion criteria. Resolution of ureteral obstruction with medical management and temporary renal drainage as needed occurred in 36 (69%) patients with a median stent duration of 16 months, and median clinical and radiographic follow up of 4.2 and 3.3 years, respectively. Recurrent obstruction after a stent-free period occurred in 9 (18%) patients. Ureterolysis was performed in 8 (15%) patients at a median of 2.2 years for medication intolerance, lack of radiographic response to medication, or persisting pain. Potential medication side effects occurred in 6 (12%) patients. CONCLUSIONS Medical management supported successful resolution of ureteral obstruction in 69% of patients without the need for ureterolysis after temporary renal drainage using stents, with rare incidence of worsening renal dysfunction or medication side effect. To date, this is the largest reported series of systematically managed RPF patients with obstructive uropathy receiving initial medical therapy and serves to counsel patients and advise urologists and nephrologists of the expected course and advantages and disadvantages of medical versus surgical management.

Abstract
15 Background: Decipher is a tissue-based genomic classifier (GC) developed and validated in the post-radical prostatectomy (RP) setting as a predictor of metastasis. We conducted the first prospective randomized controlled trial assessing the use of a prostate cancer GC, with a primary objective to determine the impact of test results on adjuvant treatment decisions. Methods: The Genomics in Michigan ImpactiNg Observation or Radiation (G-MINOR) randomized trial enrolled participants across 12 centers between January 2017-August 2018. Eligible patients had undergone RP within 9 months of enrollment, had pT3-4 disease and/or positive surgical margins, and a PSA < 0.1ng/mL. Patients were assigned to either the GC or Usual Care (UC) group using cluster-crossover block randomization. Patients and providers in both arms received a CAPRA-S recurrence risk score. Decipher scores were obtained on RP tissue of all patients, but patients and providers in the UC arm were blinded to the results. The primary endpoint was the impact of impact of GC test result on adjuvant treatment decisions compared to clinical factors alone within 18 months of RP. Results: 356 patients were randomized and 340 had at least 18 months of follow-up. Of these, all but 2 control (UC) patients had sufficient tissue to pass quality control for GC testing. Randomization resulted in 175 (51.5%) GC and 165 (48.5%) UC patients. There were no significant differences in clinical variables or Decipher scores between arms. At 18 months post-RP, 19 (10.9%) patients in the GC group and 12 (7.3%) patients in the UC group had received adjuvant treatment. In the primary analysis, availability of the GC score in the GC arm was significantly associated with adjuvant treatment in GC high-risk patients after controlling for CAPRA-S risk (OR 7.6, 95%CI 1.95-29.6, p = 0.009). In the GC arm, both GC score (OR 8.8, 95%CI 1.9-39.7, p = 0.005) and CAPRA-S score (OR 3.8, 95%CI 1.09-12.9, p = 0.04) were independently associated with adjuvant treatment in a multivariable logistic regression model. Conclusions: In the first ever randomized trial testing the impact of a prostate cancer genomic classifier on treatment decisions, the use of a GC post-RP impacted post-operative treatment in a manner concordant with classifier risk. Further follow-up will be necessary to assess the impact of GC testing on oncologic outcomes. Clinical trial information: NCT02783950. [Table: see text]

Abstract
PURPOSE Several immune checkpoint inhibitors (ICIs) are FDA approved for treatment of genitourinary (GU) malignancies. We aim to determine demographic and clinicopathologic characteristics that significantly affect clinical outcomes in patients with advanced stage GU malignancies treated with ICIs. MATERIALS AND METHODS We performed a single-center, consecutive, retrospective cohort analysis on patients with metastatic or unresectable GU malignancies who were treated with ICIs at the University of Michigan. Immune-related adverse events (irAEs), putative immune-mediated allergies, and overall response rates (ORR) were assessed. Comorbidity index scores were calculated. Survival analysis was performed to evaluate progression-free survival (PFS) and overall survival (OS), stratifying and controlling for a variety of clinicopathologic baseline factors including site of metastases. RESULTS A total of 160 patients were identified with advanced renal cell carcinoma (RCC) or urothelial carcinoma. Median PFS and OS were 5.0 and 23.6 months for RCC, and 2.8 and 9.6 months for urothelial carcinoma, respectively. Patients who experienced increased frequency and higher grade irAEs had better ICI treatment response (P < 0.0001). Presence of liver metastases was associated with poor response to ICI therapy (P = 0.001). Multivariable modeling demonstrates that patients with urothelial carcinoma and liver metastases had statistically worse PFS and OS compared to patients with RCC or other sites of metastases, respectively. CONCLUSION Greater frequency and higher grades of irAEs are associated with better treatment response in patients with RCC and urothelial malignancy receiving ICI therapy. The presence of liver metastases denotes a negative predictive marker for immunotherapy efficacy. SUMMARY Immune checkpoint inhibitors (ICI) are increasingly used to treat genitourinary (GU) malignancies. However, clinical data regarding patients with advanced-stage GU malignancies treated with ICI is lacking. Thus, we performed a single-center, retrospective cohort study on patients with metastatic and unresectable renal cell carcinoma (RCC) and urothelial carcinoma who were treated with ICIs at the University of Michigan to provide demographic and clinicopathologic data regarding this population. We specifically focused on immune-related adverse events (irAEs), immune-mediated allergies, and the associated overall response rates (ORR). To better assess performance status, we calculated comorbidity scores for all patients. Finally, survival analyses for progression-free survival (PFS) and overall survival (OS) were performed using Kaplan-Meier analysis and Cox proportional hazards modeling, stratifying and controlling for clinicopathologic baseline factors, including sites of metastases, in our multivariable analysis. A total of 160 patients were identified with advanced RCC or urothelial carcinoma. We found decreased PFS (2.8 vs. 5.0 months) and decreased OS (9.8 vs. 23.6 months) for urothelial carcinoma compared to RCC patients. We noted that patients who experienced increased frequency and higher grades of irAEs had better treatment ORR with ICI therapy (P ≤ 0.0001). The presence of liver metastases was associated with worse ORR (P = 0.001), PFS (P = 0.0014), and OS (P = 0.0028) compared to other sites of metastases including lymph node, lung, and CNS/bone. The poor PFS and OS associated with urothelial carcinoma and liver metastases were preserved in our multivariable modeling after controlling for pertinent clinical factors. We conclude that greater frequency and higher grades of irAEs are associated with better treatment response in GU malignancy patients receiving ICI, a finding that is consistent with published studies in other cancers. The presence of liver metastases represents a significantly poor predictive marker in GU malignancy treated with ICI. Our findings contribute to the growing body of literature that seeks to understand the clinicopathologic variables and outcomes associated with ICI therapy.

Abstract
Nearly half of all metastatic melanoma patients possess the BRAF V600 mutation. Several therapies are approved for advanced stage melanoma, but it is unclear if there is a differential outcome to various immunotherapy regimens based on BRAF mutation status. We retrospectively analyzed a cohort of metastatic or unresectable melanoma patients who were treated with combination ipilimumab/nivolumab (ipi/nivo) or anti-PD-1 monotherapy, nivolumab, or pembrolizumab, as first-line treatment. 235 previously untreated patients were identified in our study. Our univariate analysis showed no statistical difference in progression-free survival (PFS) or overall survival (OS) with ipi/nivo versus anti-PD-1 monotherapy in the BRAF V600 mutant cohort, but there was improved PFS [HR: 0.48, 95% CI, 0.28-0.80] and OS [HR: 0.50, 95% CI, 0.26-0.96] with ipi/nivo compared to anti-PD-1 monotherapy in the BRAF WT group. After adjusting for known prognostic variables in our multivariable analysis, the BRAF WT cohort continued to show PFS and OS benefit with ipi/nivo compared to anti-PD-1 monotherapy. Our single-institution analysis suggests ipi/nivo should be considered over anti-PD-1 monotherapy as the initial immunotherapy regimen for metastatic melanoma patients regardless of BRAF mutation status, but possibly with greater benefit in BRAF WT.
