RESUMO
PURPOSE: We sought to determine whether clinical risk factors and morphometric features on preoperative imaging can be utilized to identify those patients with cT1 tumors who are at higher risk of upstaging (pT3a). MATERIALS AND METHODS: We performed a retrospective international case-control study of consecutive patients treated surgically with radical or partial nephrectomy for nonmetastatic renal cell carcinoma (cT1 N0) conducted between January 2010 and December 2018. Multivariable logistic regression models were used to study associations of preoperative risk factors on pT3a pathological upstaging among all patients, as well as subsets with those with preoperative tumors ≤4 cm, renal nephrometry scores, tumors ≤4 cm with nephrometry scores, and clear cell histology. We also examined association with pT3a subsets (renal vein, sinus fat, perinephric fat). RESULTS: Among the 4,092 partial nephrectomy and 2,056 radical nephrectomy patients, pathological upstaging occurred in 4.9% and 23.3%, respectively. Among each group independent factors associated with pT3a upstaging were increasing preoperative tumor size, increasing age, and the presence of diabetes. Specifically, among partial nephrectomy subjects diabetes (OR=1.65; 95% CI 1.17, 2.29), male sex (OR=1.62; 95% CI 1.14, 2.33), and increasing BMI (OR=1.03; 95% CI 1.00, 1.05 per 1 unit BMI) were statistically associated with upstaging. Subset analyses identified hilar tumors as more likely to be upstaged (partial nephrectomy OR=1.91; 95% CI 1.12, 3.16; radical nephrectomy OR=2.16; 95% CI 1.44, 3.25). CONCLUSIONS: Diabetes and higher BMI were associated with pathological upstaging, as were preoperative tumor size, increased age, and male sex. Similarly, hilar tumors were frequently upstaged.

OBJECTIVE: To assess the safety and feasibility of robot-assisted retroperitoneal lymph node dissection (R-RPLND) and to compare the perioperative outcomes of R-RPLND with open RPLND (O-RPLND), as RPLND forms an integral part of the management of testis cancer and R-RPLND is a minimally invasive treatment option for this disease. MATERIALS AND METHODS: The PubMed® , Scopus® , Cochrane Central Register of Controlled Trials, and Web of Science™ databases were searched for studies reporting perioperative outcomes of primary and post-chemotherapy R-RPLND and studies comparing R-RPLND with O-RPLND. RESULTS: The search yielded 42 articles describing R-RPLND, including five comparative studies. The systematic review included 4222 patients (single-arm studies, n = 459; comparative studies, n = 3763). Of 459 patients in the single-arm studies, 271 underwent primary R-RPLND and 188 underwent post-chemotherapy R-RPLND. For primary R-RPLND, the operative time ranged from 175 to 540 min and the major complication rate was 4.1%. For post-chemotherapy R-RPLND, the operative time ranged from 134 to 550 min and the major complication rate was 8.5%. The conversion rate to open surgery was 2.2% in primary R-RPLND and 9.0% in post-chemotherapy R-RPLND. In comparison with O-RPLND, R-RPLND was associated with a lower transfusion rate (14.5% vs 0.9%, P < 0.001) and a lower complication rate (18.5% vs 7.8%, P = 0.002). CONCLUSION: Robot-assisted RPLND has acceptable perioperative outcomes in both the primary and post-chemotherapy settings but a notable rate of conversion to open surgery in the post-chemotherapy setting. Compared with O-RPLND, R-RPLND is associated with a lower transfusion rate and fewer overall complications. Given the potential impact of selection bias, the optimal patient selection criteria for R-RPLND remain to be elucidated.

Core histones including H2A, H2B, H3, and H4 are key modulators of cellular repair, transcription, and replication within eukaryotic cells, playing vital roles in the pathogenesis of disease and cellular responses to environmental stimuli. Traditional mass spectrometry (MS)-based bottom-up and top-down proteomics allows for the comprehensive identification of proteins and of post-translational modification (PTM) harboring proteoforms. However, these methodologies have difficulties preserving near-cellular spatial distributions because they typically require laser capture microdissection (LCM) and advanced sample preparation techniques. Herein, we coupled a matrix-assisted laser desorption/ionization (MALDI) source with a Thermo Scientific Q Exactive HF Orbitrap MS upgraded with ultrahigh mass range (UHMR) boards for the first demonstration of complementary high-resolution accurate mass (HR/AM) measurements of proteoforms up to 16.5 kDa directly from tissues using this benchtop mass spectrometer. The platform achieved isotopic resolution throughout the detected mass range, providing confident assignments of proteoforms with low ppm mass error and a considerable increase in duty cycle over other Fourier transform mass analyzers. Proteoform mapping of core histones was demonstrated on sections of human kidney at near-cellular spatial resolution, with several key distributions of histone and other proteoforms noted within both healthy biopsy and a section from a renal cell carcinoma (RCC) containing nephrectomy. The use of MALDI-MS imaging (MSI) for proteoform mapping demonstrates several steps toward high-throughput accurate identification of proteoforms and provides a new tool for mapping biomolecule distributions throughout tissue sections in extended mass ranges.

PURPOSE: We sought to determine if absolute prostate specific antigen (PSA) value after 6 months of androgen deprivation therapy (ADT) is predictive of subsequent survival in patients with prostate adenocarcinoma. MATERIALS AND METHODS: We performed a retrospective review of men receiving care within the Veterans Health Administration who initiated ADT for prostate adenocarcinoma. We used low- (≤0.2 ng/ml), intermediate- (>0.2 to 4 ng/ml) and high-risk (>4 ng/ml) absolute PSA values after 6-9 months of ADT, previously described in Southwest Oncology Group trial 9346. The primary endpoints were all-cause mortality and prostate cancer-specific mortality (PCSM). Kaplan-Meier survival curves for each PSA category were estimated and log-rank test was conducted. We employed Cox regression analysis adjusted for covariates and inverse propensity score weights associated with PSA categories to estimate the PSA category association with PCSM and all-cause mortality. RESULTS: We identified 9,170 patients in our cohort. Following ADT induction, 3,508 patients had low, 3,419 had intermediate and 2,243 had high PSA values. Two- and 5-year survival rates for low, intermediate and high PSA groups were 93.9% and 85.2% vs 88.6% and 71.2% vs 63.6% and 38.6%, respectively (p <0.0001). Patients in the high and intermediate PSA categories had a 15-fold and 3-fold higher risk of PCSM compared to those with PSA <0.2 ng/ml (p <0.0001). CONCLUSIONS: Absolute PSA in hormone-sensitive prostate cancer after 6-9 months of ADT is a predictor of overall mortality and PCSM. This measure can rapidly assess the efficacy of new interventions in phase 2 clinical trials.

PURPOSE: Open radical nephrectomy with inferior vena cava thrombectomy (O-CT) is standard management for renal cell carcinoma with inferior vena cava thrombus. First reported a decade ago, robotic-assisted radical nephrectomy with inferior vena cava thrombectomy (R-CT) is a minimally invasive option for this disease. We aimed to perform a systematic review to assess the safety and feasibility of R-CT in terms of perioperative outcomes and compare the outcomes between R-CT and O-CT. MATERIALS AND METHODS: The PubMed®, Scopus®, Cochrane Central Register of Controlled Trials and Web of ScienceTM databases were searched using the free-text and MeSH terms "renal cell carcinoma," "inferior vena cava," "thrombosis" or "thrombus," "robot" and "thrombectomy." Studies reporting perioperative outcomes of R-CT and studies comparing R-CT with O-CT were included. The review was done in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. RESULTS: The search retrieved 28 articles describing R-CT, including 7 comparative studies. This systematic review included 1,375 patients, out of which 329 patients were in single-arm studies and 1,046 patients were in comparative studies. Of the 329 patients who underwent R-CT, 14.7% were level I, 60.9% level II, 20.4% level III and 2.5% level IV thrombus. Operative time ranged from 150 to 530 minutes; blood transfusion was administered in 38.2% (126). The overall complication rate was 30.3% (99). R-CT, in comparison to O-CT, was associated with a lower blood transfusion rate (18.4% vs 64.3%, p=0.002) and a lower complication rate (14.5% vs 36.7%, p=0.005). Major complication and 30-day mortality rates were similar in both groups. CONCLUSIONS: R-CT has acceptable perioperative outcomes in carefully selected patients. Compared with O-CT, R-CT is associated with a lower blood transfusion rate and fewer overall complications. In experienced hands with carefully selected patients, R-CT is feasible and safe, with acceptable outcomes; however, selection bias limits definitive inference of these results, and optimal patient selection criteria remain to be described.

BACKGROUND: A recently reported phase III randomized trial comparing open and minimally invasive hysterectomy showed significantly higher rates of local recurrence after minimally invasive surgery (MIS) for cervical cancer. This raised concerns regarding patterns of recurrences and survival after MIS in general. This study aims to determine the effect of MIS on all-cause mortality among patients undergoing radical nephrectomy for Stage I and II renal cell carcinoma (RCC). METHODS: We utilized the National Cancer Database to identify patients diagnosed with clinical stage I-II RCCs between 2010 and 2013. Patients for whom a laparoscopic or robotic radical nephrectomy was attempted were compared to patients who underwent open radical nephrectomy (ORN). Adjusted regression models with inverse probability propensity score weighting (IPW) were utilized to identify independent predictors of receiving MIS. All-cause mortality rates were compared using IPW survival functions and log-rank tests. Adjusted Cox proportional hazard models were fitted to determine independent predictors of OS. RESULTS: 27,642 patients were identified; 11,524 (41.7%) had MIS, while 16,118 (58.3%) had ORN. Kaplan-Meier survival curves in the IPW cohort showed significant OS advantage for patients who underwent MIS (p < 0.001). Furthermore, length of hospital stays (3 vs. 4 days), 30 day readmission rates (2.4 vs. 2.87%), 30 day (0.53 vs. 0.96%) and 90 day mortality rates (1.04 vs. 1.77%) were significantly higher in the ORN group (p < 0.001). CONCLUSIONS: MIS was associated with better OS outcomes compared to ORN for stage I and II RCC. In addition, MIS had lower post-operative readmission, 30- and 90 day mortality rates.

INTRODUCTION: To investigate the impact of facility type and volume on survival in patients with metastatic renal cell carcinoma (mRCC). MATERIALS AND METHODS: We investigated the National Cancer Database for patients with mRCC. Patients were stratified according to treatment facility type (academic vs. non-academic) and facility volume (high, intermediate, and low). Kaplan-Meier survival estimates and Cox proportional hazard models were fitted to evaluate overall survival (OS) as a function of facility type, volume, and different treatment modalities. RESULTS: A total of 27,598 patients were identified, of which 10,938 (40%) were treated at academic centers (AC) and 16,131 (60%) at non-academic centers (non-AC). Overall, 19,904 patients (72%) were treated in high-volume hospitals (HVH). Among patients treated at AC, 94% were treated at HVHs. Patients treated at AC were more likely to receive immunotherapy, undergo cytoreductive nephrectomy (CN) and metastasectomy. The 2 and 5 year OS rates for patients treated in AC were 29.7% (CI 28.8%-30.6%) and 13% (CI 12%-14%) vs. 21.7% (CI 21%-22.4%) and 8.4% (CI %7.91-%8.99) in the Non-AC, respectively (p < 0.001). Multivariate Cox regression analysis identified treatment at AC as an independent predictor of survival (HR 0.85, 95% CI 0.81-0.91, p < 0.001). Undergoing CN and receipt of immunotherapy was also associated with a survival benefit (HR 0.41, CI 0.40-0.43 and HR 0.63, CI 0.59-0.68 respectively, p < 0.001). CONCLUSIONS: Treatment at ACs and HVHs was associated with a survival benefit in patients with mRCC. Patients treated at AC were more likely to receive immunotherapy, undergo CN and metastasectomy.

INTRODUCTION: Urology residents are encouraged to learn ultrasound (U/S) imaging, yet there are few tools available for teaching and assessing a resident`s competence. The aim of this study was to test the new SonoSim LiveScan® and to propose a competency-based assessment model for the urology graduate medical education. MATERIALS AND METHODS: Urology residents attended an interactive training session covering the urological U/S techniques guided by the assessment model developed by the authors. Faculty members evaluated the residents using defined objectives, and the residents were surveyed on their comfort level for performing each of the model tasks. A subset of the residents then underwent a structured testing using the SonoSim LiveScan device 6 months following the training. The model developed assessed: general U/S setup, structure identification, and pathologic clinical scenarios. RESULTS: The residents felt most comfortable in identifying the bladder (4.73/5) and the kidneys (4.53/5) during the training sessions. They felt least comfortable while testing for total ureteric obstruction (3.13/5). All the residents were confident that additional U/S training sessions would improve their comfort level in performing the assessed objectives. Resident`s assessment performed at 6 months had a median test score of 15.5/20 and the assessment scores increased with resident seniority. Self-reported comfort, however, did not seem to correlate with seniority. In general, the residents felt that the SonoSim device was highly functional (4.4/5) and the pathologic assessments in particular were very helpful (4.4/5). CONCLUSIONS: Through pilot testing, we propose that a competency-based assessment used with the SonoSim LiveScan could guide the resident`s education through the acquisition of U/S skills and warrants testing in a larger cohort.
RESUMO
PURPOSE: A systematic review and meta-analysis of clinical trials was undertaken to compare percutaneous thermal ablation versus partial nephrectomy (PN) for stage T1 renal tumors. MATERIALS AND METHODS: A comprehensive search of major databases was conducted from October 2000 to July 2016. Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines were followed. Incidences of all-cause mortality (ACM), cancer-specific mortality (CSM), local recurrence (LR), and metastases, as well as complication rates and changes in estimated glomerular filtration rate (eGFR), were evaluated. RESULTS: Inclusion criteria were met by 15 of 961 papers. These studies represented 3,974 patients who had undergone an ablative procedure (cryoablation or radiofrequency ablation; n = 1,455; 37%) or PN (n = 2,519; 63%). ACM and CSM rates were higher for ablation than for PN (hazard ratio [HR], 2.11; 95% confidence interval [CI], 1.54-2.87 [P < .05]; HR, 3.84; 95% CI, 1.66-8.88 [P < .05], respectively). No statistically significant difference in LR rate or risk of metastasis was seen between ablation and PN (HR, 1.32; 95% CI, 0.79-2.22 [P = .22]; HR, 1.83; 95% CI, 0.67-5.01 [P = 0.23], respectively). Complication rates were lower for ablation than for PN (13% vs 17.6%; odds ratio, 0.49; 95% CI, 0.25-0.94; P < .05). A significantly greater decrease in eGFR was observed after PN (13.09 mL/min/1.73 m2) vs ablation therapy (4.47 mL/min/1.73 m2). CONCLUSIONS: Thermal ablation showed no significant difference in LR or metastases compared with PN. Thermal ablation was associated with a lower morbidity rate and a lesser reduction in eGFR compared with PN, but with higher ACM and CSM rates.

OBJECTIVES: Radical prostatectomy (RP) for locally advanced prostate cancer may reduce the risk of metastasis and cancer-specific death. Herein, we evaluated the outcomes for patients with pT4 disease treated with RP. MATERIALS AND METHODS: Among 19,800 men treated with RP at Mayo Clinic from 1987 to 2010, 87 were found to have pT4 tumors. Biochemical recurrence (BCR)-free survival, systemic progression (SP) free survival and overall survival (OS) were estimated using the Kaplan-Meier method and compared with the log-rank test. Cox proportional hazards regression models were used to assess the association of clinic-pathological features with outcome. RESULTS: Median follow-up was 9.8 years (IQR 3.6, 13.4). Of the 87 patients, 50 (57.5%) were diagnosed with BCR, 30 (34.5%) developed SP, and 38 (43.7%) died, with 11 (12.6%) dying of prostate cancer. Adjuvant androgen deprivation therapy was administered to 77 men, while 32 received adjuvant external beam radiation therapy. Tenyear BCR-free survival, SP-free survival, and OS was 37%, 64%, and 70% respectively. On multivariate analysis, the presence of positive lymph nodes was marginally significantly associated with patients' risk of BCR (HR: 1.94; p=0.05), while both positive lymph nodes (HR 2.96; p=0.02) and high pathologic Gleason score (HR 1.95; p=0.03) were associated with SP. CONCLUSIONS: Patients with pT4 disease may experience long-term survival following RP, and as such, when technically feasible, surgical resection should be considered in the multimodal treatment approach to these men.

OBJECTIVE: To review our experience with radical cystectomy for small cell carcinoma of the bladder, to compare outcomes with a cohort of patients with urothelial carcinoma, and to determine the effect of adjuvant chemotherapy and pathology re-review in this setting. METHODS: Among 2427 patients who underwent radical cystectomy, 68 patients had small cell carcinoma of the bladder. Patients with small cell carcinoma of the bladder were compared with an unmatched cohort of 1146 patients with urothelial carcinoma, and were then matched (1:2) based on TNM stage. Survival was estimated using the Kaplan-Meier method, and Cox models were used to evaluate association of clinicopathological features with outcome. RESULTS: Among the 68 small cell carcinoma of the bladder patients, 37 (54%) were found to have small cell carcinoma of the bladder only after pathology re-review. Patients with small cell carcinoma of the bladder had a higher rate of advanced (pT3/4) tumor stage (84% vs 46%; P < 0.0001) and pN+ disease (37% vs 20%; P = 0.001) compared with patients with urothelial carcinoma. When matched for stage and lymph node status, no significant difference in 5-year cancer-specific survival was observed between the two groups (27% vs 29%; P = 0.64). Among small cell carcinoma of the bladder patients, those receiving adjuvant chemotherapy had improved 5-year overall survival compared with patients who did not receive adjuvant chemotherapy (43% vs 20%; P = 0.03), and a trend toward superior cancer-specific survival (40% vs 23%; P = 0.07). CONCLUSIONS: Small cell carcinoma of the bladder is often an unrecognized pathological entity, which is associated with a higher rate of locally advanced and N+ disease. However, although when matched for pathological features, survival outcomes appear similar to urothelial carcinoma. Small cell carcinoma of the bladder patients receiving adjuvant chemotherapy had improved overall survival and cancer-specific survival, and these results require further investigation.

OBJECTIVES: To evaluate the differences in estimated glomerular filtration rate decline by urinary diversion type (incontinent diversion vs continent diversion) and preoperative estimated glomerular filtration rate among patients undergoing radical cystectomy and urinary diversion. METHODS: We evaluated 1383 patients treated with radical cystectomy between 1980-2006 who had a preoperative estimated glomerular filtration rate of 45-89 mL/min/1.73 m(2). Estimated glomerular filtration rate was estimated using Chronic Kidney Disease Epidemiology Collaboration equations, and patients were stratified by preoperative estimated glomerular filtration rate into chronic kidney disease 2 (estimated glomerular filtration rate 60-89 mL/min/1.73 m(2)) and chronic kidney disease 3a (estimated glomerular filtration rate 45-59 mL/min/1.73 m(2)). Multiple definitions of estimated glomerular filtration rate decline were evaluated: (i) 10-point decline in estimated glomerular filtration rate; (ii) 20% decline in estimated glomerular filtration rate; and (iii) 10% decline in estimated glomerular filtration rate. Time to estimated glomerular filtration rate decline was compared using the Kaplan-Meier method stratified by diversion type. Cox regression models were used to evaluate the association of diversion type with estimated glomerular filtration rate decline risk. RESULTS: In total, 74% (1021/1383) of patients underwent incontinent diversion and 26% (362/1383) underwent continent diversion. Preoperative chronic kidney disease 2 and chronic kidney disease 3a were noted among 59% and 41% of patients who underwent incontinent diversion, versus 74% and 26% with continent diversion. Median follow up after RC was 11.2 years. The rate of estimated glomerular filtration rate decline in patients with incontinent diversion versus continent diversion was similar when stratified by preoperative chronic kidney disease 2 and preoperative chronic kidney disease 3a, regardless of estimated glomerular filtration rate decline definition. On multivariable analysis, continent diversion was not associated with estimated glomerular filtration rate decline for patients with preoperative chronic kidney disease 3a. CONCLUSIONS: The risk of estimated glomerular filtration rate decline over 10 years was not significantly different after incontinent diversion versus continent diversion among patients with preoperative chronic kidney disease 2 or chronic kidney disease 3a. Continent diversion does not appear to confer an independently increased risk of estimated glomerular filtration rate decline in patients with preoperative chronic kidney disease 3a.

PURPOSE: We evaluated the long-term natural history of renal function after radical cystectomy with urinary diversion and determined factors associated with decreased renal function. MATERIALS AND METHODS: We reviewed the records of 1,631 patients who underwent radical cystectomy between 1980 and 2006. The estimated glomerular filtration rate was calculated preoperatively and at various intervals after surgery. A renal function decrease was defined as a greater than 10 ml per minute/1.73 m(2) reduction in the estimated glomerular filtration rate. Multivariate analysis was done to evaluate the association of clinicopathological features, incontinent vs continent diversion type and postoperative complications with decreased renal function. RESULTS: A total of 1,241 patients (76%) underwent incontinent diversion and 390 (24%) underwent continent diversion. Median followup after radical cystectomy in patients alive at last followup was 10.5 years (IQR 7.1, 15.3). The median preoperative estimated glomerular filtration rate was higher in the continent diversion cohort (67 vs 59 ml per minute/1.73 m(2), p <0.0001). This difference was maintained until 7 years postoperatively, after which no difference was noted in renal function by diversion type. By 10 years after radical cystectomy the risk of a renal function decrease was similar for incontinent and continent diversion (71% and 74%, respectively, p = 0.13). On multivariate analysis risk factors associated with decreased renal function included age (HR 1.03, p <0.0001), preoperative estimated glomerular filtration rate (HR 1.05, p <0.0001), chronic hypertension (HR 1.2, p = 0.01), postoperative hydronephrosis (HR 1.2, p = 0.03), pyelonephritis (HR 1.3, p = 0.01) and ureteroenteric stricture (HR 1.6, p <0.0001). CONCLUSIONS: Decreased renal function is noted in most patients during long-term followup after radical cystectomy. Postoperative hydronephrosis, pyelonephritis and ureteroenteric stricture represent potentially modifiable factors associated with a decrease. Choice of urinary diversion was not independently associated with decreased renal function.

PURPOSE: To evaluate the association of gender with survival following radical cystectomy (RC) for patients with pT4 bladder cancer. MATERIALS AND METHODS: We reviewed our institutional registry of 2,088 patients treated with RC between 1980 and 2005 to identify 128 with pT4 tumors, including 91 males and 37 females. Survival was estimated using the Kaplan-Meier method and compared with log-rank test. Cox hazard regression models were used to analyze the association of clinicopathologic demographics, including gender, with outcome. RESULTS: A total of 7 women and 30 men with pT4 tumor received perioperative chemotherapy. Median postoperative follow-up was 10.5 years, during which time 27 patients experienced local recurrence (LR) and 120 died, including 90 who died from bladder cancer. Women with pT4 tumor trended to have higher 5-year LR-free survival (72 vs. 59 %; p = 0.83), cancer-specific survival (31 vs. 17 %; p = 0.50), and overall survival (19 vs. 11 %; p = 0.33), although these differences did not reach statistical significance. On multivariate analysis, moreover, gender was not significantly associated with LR (HR 0.96; p = 0.93), cancer-specific mortality (HR 1.05; p = 0.87), or all-cause mortality (ACM) (HR 1.14; p = 0.58). Instead, poor ECOG performance status and pN+ disease were associated with an increased risk of ACM, while removal of a greater number of lymph nodes was associated with decreased ACM. CONCLUSION: We did not find gender-specific disparities in survival following RC for pT4 bladder cancer. Prognosis was instead driven by patient performance status and lymph node status.

INTRODUCTION: Most urologic surgeons will experience surgical complications during their career. These complications can traumatize the surgeon. A national survey of AUA members was conducted to better understand the impact of surgical complications on mental, emotional, and physical health. METHODS: An anonymous survey was distributed to a random sample of 4528 AUA members (US urologists and trainees). Survey items were designed to identify the prevalence of surgical complications, and consequential mental, emotional, and physical impact on the surgeon. Also assessed was the support infrastructure available to urologists who experienced complications. RESULTS: The survey was completed by 467 urologists (10.3% response rate), 432 (95%) of whom reported having experienced a serious complication. The most common mental/emotional experiences were anxiety (85%), guilt/shame (81%), and grief/sadness/depression (71%). The most common physical symptoms reported were insomnia (62%), loss of appetite (23%), and headache (13%). Approximately 94% of respondents reported that they did not receive any counseling, and 69% reported not receiving any emotional support following the incident. Urologists reported that shame, lack of administrative time, fear, stigma, and guilt were barriers to seeking support. CONCLUSIONS: The overwhelming majority of urologists experience significant complications. These complications are associated with a high incidence of physical and emotional distress, and there is poor access to support. There is an opportunity for the AUA and other agencies to address barriers to seeking and accessing care for urologists who experience mental, emotional, and physical distress after experiencing surgical complications.

OBJECTIVES: To evaluate the association between surgical modality (RARC vs. ORC) and the risk of 30-day complications. MATERIALS AND METHODS: We utilized the American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) Cystectomy-Targeted database from 2019 to 2021. The primary outcome was a composite of major complications including 30-day mortality, reoperation, cardiac events, and stroke. Secondary outcomes included individual major and cystectomy-specific complications. Propensity score matching (PSM) was employed to minimize inherent differences within our cohort. We performed logistic regression to assess the association between outcomes of interest and operative modality. RESULTS: We found no difference between operative modality and the primary outcome, however, RARC was associated with a 70% lower risk of 30-day mortality (OR 0.30, 95% CI 0.13-0.70) and had favorable outcomes with respect to respiratory, deep venous thrombosis, wound complications, and length of stay. Limitations are related to residual confounding given the observational methodology. CONCLUSIONS: RARC was associated with reduced risk of multiple 30-day complications, including mortality, as well as organ system and cystectomy-specific outcomes. These data support the clinical benefit of increased adoption of RARC.
