Prognostic factors and treatment impact on overall survival in patients with renal neuroendocrine tumour.

Background: Renal neuroendocrine neoplasms (R-NEN) are exceptionally rare tumours characterized by high mortality rates. Objective: The objective of this study is to analyse prognostic factors and treatment impact on overall survival in patients with R-NEN. Design setting and participants: We identified all patients with R-NEN in the National Cancer Database (NCDB) from 2004 to 2019 and identified prognostic factors for improved survival. Results and limitations: Of 542 R-NEN cases, 166 (31%) were neuroendocrine tumour grade 1 (NET-G1), 14 (3%) were neuroendocrine tumour grade 2 (NET-G2), 169 (31%) were neuroendocrine carcinoma (NEC-NOS), 18 (3%) were large cell neuroendocrine carcinoma (LC-NEC) and 175 (32%) were small cell neuroendocrine carcinoma (SC-NEC). Median overall survival for all patients in the study was 44.88 months (SE, 4.265; 95% CI, 27.57-62.19). Median overall survival was 7.89 months (SE 0.67; 95% CI, 6.58-9.20) for patients without surgical intervention and 136.61 months (SE 16.44; 95% CI, 104.38-168.84, p < 0.001) for patients who underwent surgery. Increased age (HR, 1.05; 95% CI, 1.03-1.06; p < 0.001), T4 stage disease (HR, 3.17; 95% CI, 1.96-5.1; p < 0.001), NEC-NOS histology (HR, 2.82; 95% CI, 1.64-4.86; p < 0.001), LC-NEC histology (HR, 2.73; 95% CI, 1.04-7.17; p = 0.041) and SC-NEC histology (HR, 5.17; 95% CI, 2.95-9.05; p < 0.001) were all positive predictors of worsening overall survival. The main limitation of the study is its retrospective design. Conclusion: R-NEN is an aggressive tumour characterized by high mortality rates. Surgery continues to be the mainstay of treatment and has shown to provide a survival benefit for most patients. Patient Summary: R-NEN is composed of several tumour histologies that differ based on their aggressiveness with NEC-NOS and SC-NEC being the most lethal. Surgery, predominantly through minimally invasive approaches, is the mainstay of treatment and has a clear survival benefit.

Transurethral Resection of Bladder Tumor Outcomes Are Predicted by a 5-Item Frailty Index.

OBJECTIVE: To evaluate the mFI-5 as a predictor of postoperative outcomes following transurethral resection of bladder tumor (TURBT). METHODS: The National Surgical Quality Improvement Program database was queried for TURBT cases from 2015-2019. mFI-5 scores were calculated by assigning a point to chronic obstructive pulmonary disease, congestive heart failure, dependent functional status, hypertension, and diabetes. Patients were stratified by mFI-5 scores. Demographics and 30-day outcomes including Clavien-Dindo (CD) complications, mortality, and increased healthcare resource utilization (HCRU) were compared. HCRU outcomes included prolonged length of stay, unplanned readmission, and discharge to continued care. Multivariate regression assessed the predictive value of mFI-5 scores on outcomes. RESULTS: 40,278 TURBT cases were identified (mFI-5 =0: 12,400, mFI-5 =1: 17,328, mFI-5 =2: 9225, mFI-5 ≥3: 1416). Patients with higher mFI-5 scores were more likely to be older, male, White, and have larger tumors, all P < .05. Increasing mFI-5 scores resulted in increased frequency of all adverse outcomes, all P < .001. On multivariate analysis, mFI-5 ≥ 3 classification was a predictor of CD I/II (OR=1.280), CD IV (OR=2.539), mortality (OR=2.202), HCRU (OR=2.094), prolonged length of stay (OR=2.136), discharge to continued care (OR=3.401), and unplanned readmission (OR=1.705), all P < .05. A mFI-5 ≥ 3 demonstrated a sensitivity ranging from 6.0%-13.5% and a specificity ranging from 96.6%-97.0% for all outcomes. CONCLUSION: The mFI-5 is an easily ascertainable preoperative risk assessment tool that is a predictor of adverse clinical and HCRU outcomes following TURBT.

Differences in cancer presentation, treatment, and mortality between rural and urban patients diagnosed with kidney cancer in the United States.

INTRODUCTION: Rural-urban discrepancies in care and outcomes for kidney cancer (KCa) in the United States remains poorly understood. Our study aims to improve our understanding of the influence of rurality on KCa outcomes in the United States by analyzing differences in presentation, treatment, and mortality between urban areas (UAs) and rural areas (RAs) in the Surveillance, Epidemiology, and End Results (SEERs) database. METHODS: SEERs data was queried from 2000 to 2019 for KCa patients. Patient counties were classified as UAs, rural adjacent areas (RAAs), or rural nonadjacent areas (RNAs) using Rural Urban Continuum Codes. Demographic, tumor characteristics, and treatment variables were compared. Propensity score matching was performed to create matched UA-RAA and UA-RNA cohorts. Multivariate regression evaluated rural-urban status as a predictor of treatment selection. Multivariate cox regression assessed the predictive value of rural-urban status for overall survival (OS) and cancer-specific survival (CSS). Kaplan-Meier analysis was used to generate survival curves for OS and CSS. RESULTS: 179,509 KCa patients were identified (UA = 87.0%, RAA = 7.7%, RNA = 5.3%). Patients in RAs were more likely to present with tumors of higher grade and stage than UAs. Following multivariate analysis, rural residency predicted undergoing nephrectomy (RAA: OR = 1.177, RNA: OR = 1.210) but was a negative predictor of receiving partial nephrectomy (RAA: OR = 0.744, RNA: OR = 0.717), all P < 0.001. Multivariate cox regression demonstrated that RAA or RNA residency was predictive of overall and cause-specific mortality. After matching, median OS was 151, 124, and 118 months for UA, RAA, and RNA cohorts respectively; mean CSS was 152, 147, and 144 months for UA, RAA, and RNA cohorts, respectively, all P < 0.001. Stage-specific analysis of CSS demonstrated significantly poorer CSS among RNA patients for localized, regionalized, and distant KCa after matching. Only RAA patients with localized KCa experienced significantly lower CSS than UA patients. CONCLUSIONS: Patients in RAs are more likely to present with advanced KCa at diagnosis compared to those in UAs and may also experience different treatment options including a lesser likelihood of undergoing partial nephrectomy. Rural patients with KCa also demonstrated significantly worse OS and CSS compared to their urban counterparts. Further patient-level studies are required to better understand the discrepancy in CSS between urban and rural patients diagnosed with KCa.

Infections After Adoption of Antibiogram-directed Prophylaxis and Intracorporeal Urinary Diversion for Robot-assisted Radical Cystectomy.

BACKGROUND: Enhanced recovery after surgery (ERAS) has significantly decreased the morbidity associated with radical cystectomy. However, infectious complications including sepsis, urinary tract (UTIs), wound (WIs), and intra-abdominal (AIs) infections remain common. OBJECTIVE: To assess whether intracorporeal urinary diversion (ICUD) and antibiogram-directed antimicrobial prophylaxis would decrease infections after robotic-assisted radical cystectomy (RARC). DESIGN, SETTING, AND PARTICIPANTS: A retrospective analysis was performed of a prospectively maintained database of patients undergoing RARC between 2014 and 2022 at a tertiary care institution, identifying two groups based on adherence to a prospectively implemented modified ERAS protocol for RARC: modified-ERAS-ICUD and antibiogram-directed ampicillin-sulbactam, gentamicin, and fluconazole prophylaxis were utilized (from January 2019 to present time), and unmodified-ERAS-extracorporeal urinary diversion (UD) and guideline-recommended cephalosporin-based prophylaxis regimen were utilized (from November 2014 to June 2018). Patients receiving other prophylaxis regimens were excluded. INTERVENTION: ICUD and antibiogram-directed infectious prophylaxis. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcome was UTIs within 30 and 90 d postoperatively. The secondary outcomes were WIs, AIs, and sepsis within 30 and 90 d postoperatively, and Clostridioides difficile infection (CDI) within 90 d postoperatively. RESULTS AND LIMITATIONS: A total of 396 patients were studied (modified-ERAS: 258 [65.2%], unmodified-ERAS: 138 [34.8%]). UD via a neobladder was more common in the modified-ERAS cohort; all other intercohort demographic differences were not statistically different. Comparing cohorts, modified-ERAS had significantly reduced rates of 30-d (7.8% vs 15.9%, p = 0.027) and 90-d UTIs (11.2% vs 25.4%, p = 0.001), and 30-d WIs (1.2% vs. 8.7%, p < 0.001); neither group had a WI after 30 d. Rates of AIs, sepsis, and CDI did not differ between groups. On multivariate regression, the modified-ERAS protocol correlated with a reduced risk of UTIs and WIs (all p < 0.01). The primary limitation is the retrospective study design. CONCLUSIONS: Utilization of ICUD and antibiogram-based prophylaxis correlates with significantly decreased UTIs and WIs after RARC. PATIENT SUMMARY: In this study of infections after robotic radical cystectomy for bladder cancer, we found that intracorporeal (performed entirely inside the body) urinary diversion and an institution-specific antibiogram-directed antibiotic prophylaxis regimen led to fewer urinary tract infections and wound infections at our institution.

The Role of Experience: How Case Volume and Endourology-Fellowship Training Impact Surgical Outcomes for Ureteroscopy.

Introduction: Surgical experience is associated with superior outcomes in complex urologic cases, such as prostatectomy, nephrectomy, and cystectomy. The question remains whether experience is predictive of outcomes for less complex procedures, such as ureteroscopy (URS). Our study examined how case volume and endourology-fellowship training impacts URS outcomes. Methods: We retrospectively reviewed URS cases from 2017 to 2019 by high ureteroscopy volume urologists (HV), low ureteroscopy volume urologists (LV), endourology-fellowship trained (FT), and non-endourology FT (NFT) urologists. Surgical outcomes including stone-free rate (SFR), complication and reoperation rates, and postoperative imaging follow-up were analyzed between groups. Results: One thousand fifty-seven cases were reviewed across 23 urologists: 6 HV, 17 LV, 3 FT, and 20 NFT. Both FT and HV operated on more complex cases with lower rates of pre-stented patients. HV also operated on patients with higher rates of renal stones, lower pole involvement, and prior failed procedures. Despite this, FT and HV showed between 11.7% and 14.4% higher SFR, representing 2.7- to 3.6-fold greater odds of stone-free outcomes for primary and secondary stones. Additionally, HV and FT had a 4.9% to 7.8% lower rate of postoperative complications and a 3.3% to 4.3% lower rate of reoperations, representing 1.9- to 4.0-fold lower odds of complications. Finally, their patients had a 1.6- to 2.1-fold higher odds of postoperative imaging follow-up with a greater proportion receiving postoperative imaging within the recommended 3-month postoperative period. Conclusions: More experienced urologists, as defined by higher case volume and endourology-fellowship training, had higher SFR, lower complication and reoperation rates, and better postoperative imaging follow-up compared with less experienced urologists. Although less experienced urologists had outcomes in-line with clinical and literature standards, continued training and experience may be a predictor of better outcomes across multiple URS modalities.

Medium-Term Real-World Outcomes of Minimally Invasive Surgical Therapies for Benign Prostatic Hyperplasia: Water Vapor Thermal Therapy (Rezum) vs Prostatic Urethral Lift (UroLift) in a High-Volume Urban Academic Center.

Purpose: Water vapor thermal therapy (WVTT, i.e., Rezum®) and prostatic urethral lift (PUL, i.e., Urolift®) are minimally invasive surgical therapy (MIST) options for benign prostatic hyperplasia (BPH). Few studies have directly compared the two procedures. We examined the clinical characteristics and postoperative outcomes of patients undergoing WVTT and PUL at our high-volume urban academic center. Methods: We reviewed our institutional MIST database to identify patients with prostate sizes ≥30 and ≤80 cc who underwent WVTT or PUL for treatment of BPH between January 2017 and September 2021. Pre- and postoperative outcomes, including retreatment rates, American Urological Association symptom score (AUA-SS), maximum flow (Qmax), postvoid residual (PVR), medication usage, trial of void success rates, catheterization requirements, and postoperative complications within 90 days were extracted and compared between procedures. Results: Three hundred seven patients received WVTT and 110 patients received PUL with average follow-up times of 11.3 and 12.8 months, respectively. WVTT patients showed significant improvements in AUA-SS, Qmax, and PVR, whereas PUL patients showed improvements in only AUA-SS and Qmax. Both WVTT and PUL patients with longitudinal follow-up demonstrated improvements in AUA-SS, Qmax, and PVR. Postoperatively, alpha-blocker utilization was significantly decreased following both WVTT and PUL (WVTT: 73.9%-46.6%, PUL: 76.4%-38.2%, both p < 0.001). Compared to patients receiving PUL, WVTT patients more frequently reported postoperative dysuria (22.8% vs 8.3%, p = 0.001) and nonclot-related retention (18.9% vs 7.3%, p = 0.005); PUL patients more frequently experienced postoperative clot retention (7.3% vs 2.6%, p = 0.027). There were no differences in rates of postoperative bladder spasm, trial of void success, urinary tract infections, or emergency department visits. Postoperative erectile dysfunction and retrograde ejaculation were rare and occurred at similar rates. Conclusion: In the real-world setting, WVTT and PUL have similar medium-term efficacy in improving symptoms and decreasing medication utilization for patients with BPH. Differences in postoperative complication profiles should inform patient counseling.

The Utilization and Safety of Same-Day Discharge After Transurethral Benign Prostatic Hyperplasia Surgery: A Case-Control, Matched Analysis of a National Cohort.

OBJECTIVE: To analyze the utilization and safety of same-day (SDD) vs standard-length discharge (SLD) for transurethral resection (TURP), holmium laser enucleation (HoLEP), and GreenLight photovaporization (GL-PVP) of the prostate. METHODS: Using the 2015-2019 ACS-NSQIP files, the annual proportion of TURP, HoLEP, and GL-PVP performed with SDD (length of stay [LOS] = 0 days) was calculated. Patients were stratified by LOS into SDD and SLD (TURP: LOS = 1-3 days, HoLEP and GL-PVP: LOS = 1-2 days); those with longer LOS were excluded. Patients were matched 1:1 by age, body mass index, American Society of Anesthesiologists score, and modified Charlson Comorbidity Index score. We compared 30-day unplanned readmissions, reoperations, and Clavien-Dindo (CD) complications between SLD and SDD, and evaluated predictors of adverse outcomes using logistic regression. RESULTS: Most GL-PVP patients underwent SDD, compared to a minority of TURP and HoLEP patients. SDD utilization increased, remained stable, and decreased over time for HoLEP, TURP, and GL-PVP, respectively. For 46,898 included cases (31,872 TURP, 2,901 HoLEP, 12,125 GL-PVP), rates of reoperation, CD I/II, or CD IV complications were comparable before and after matching. Compared to SLD, 30-day unplanned readmission rates for matched SDD patients were lower following TURP (3.48% vs 4.25%, P = .013) and HoLEP (1.93% vs 4.43%, P = .003). On multivariate regression, SLD correlated with unplanned readmission after TURP and HoLEP for both unmatched and matched cohorts. CONCLUSION: For appropriately selected patients, SDD after TURP, HoLEP, and GL-PVP did not confer increased risk of 30-day complications, suggesting patient selection for SDD is being done with appropriate safety nationally.

Implementation of a nonopioid protocol following robot-assisted radical cystectomy with intracorporeal urinary diversion.

PURPOSE: The implementation of robot-assisted radical cystectomy (RARC) with intracorporeal urinary diversion (ICUD) for management of patients with muscle-invasive or high-risk noninvasive bladder cancer has increased in utilization over the last decade. Here, we seek to describe institutional opioid prescription and utilization patterns following implementation of a nonopioid (NOP) perioperative pain management protocol in patients who received RARC with ICUD. MATERIALS AND METHODS: The records of all patients who underwent RARC that utilized a NOP perioperative pain management protocol at a single academic institution from 2016 to 2020 were retrospectively reviewed. Descriptive statistical analyses were performed. For comparison, we included 74 consecutive patients who received the same NOP protocol with extracorporeal urinary diversion (ECUD). RESULTS: A total of 116 patients who received ICUD were included in our analysis. The median operation time for the ICUD group was 305 minutes (interquartile range [IQR]: 262-352). 12.1% (n = 14) of patients who underwent ICUD required narcotics during inpatient hospitalization. For these patients, the median morphine milligram equivalent requirement was 52.0 (IQR: 7.62-157). Additionally, only 12.1% (n = 14) of patients were prescribed opioids postoperatively at discharge. We identified that within 6 months of surgery only 5 (4.3%) patients required a second narcotic prescription. Furthermore, of patients who did not use mu-opioid blockers, a minority experienced postoperative ileus (15.7%, n = 16). 30- and 90-day all Clavien complication rates for patients were 44.8% (n = 52) and 49.1% (n = 57), respectively. Nineteen (16.4%) patients were readmitted within 30 days of discharge, of which none were pain related. When compared to ECUD, patients who received ICUD experienced similar complication and readmission rates. CONCLUSIONS: The implementation of a NOP protocol for patients undergoing RARC with ICUD allows for both decreased postoperative narcotic use and reduced need for narcotic prescriptions at discharge with acceptable complication and readmission rates.

Robotic-assisted simple prostatectomy versus open simple prostatectomy: a New York statewide analysis of early adoption and outcomes between 2009 and 2017.

The factors driving early adoption of robotic-assisted simple prostatectomy (RASP) for large gland BPH have not yet been identified. This study aims to determine the patient, provider, and facility level differences and predictors in undergoing RASP versus OSP. This population-based cohort study used data from the all-payer New York State Statewide Planning and Research Cooperative System (SPARCS) database. Patient, provider, and facility characteristics for each cohort were analyzed, and a multivariate analysis was conducted to identify predictive factors associated with undergoing RASP versus OSP. From 2009 to 2017, 1881 OSP and 216 RASP cases were identified. RASP utilization increased from 2.6% of all cases in 2009 to 16.8% in 2017. Patient demographics were similar between both cohorts. Median length of stay was shorter for RASP patients (3 vs. 4 days, p < 0.001), and OSP was associated with a long length of stay (> 7 days) (p < 0.001). There were no significant differences in 30- and 90-day readmission rates or 1-year mortality. More OSP patients were discharged to continued care facilities than RASP patients (p = 0.049), and more RASP patients were discharged to home compared to OSP patients (p = 0.035). Positive predictors for undergoing RASP included teaching hospital status, medium and high hospital bed volume, high hospital operative volume, high surgeon volume, and surgeons that graduated within 15 years of surgery. As RASP shows favorable perioperative outcomes, the diffusion of robotic technology and newer graduates entering the workforce may augment the upward trend of RASP utilization.

Outcomes assessment in intrahepatic cholangiocarcinoma using qualitative and quantitative imaging features.

BACKGROUND: To assess the performance of imaging features, including radiomics texture features, in predicting histopathologic tumor grade, AJCC stage, and outcomes [time to recurrence (TTR) and overall survival (OS)] in patients with intrahepatic cholangiocarcinoma (ICC). METHODS: Seventy-three patients (26 M/47F, mean age 63y) with pre-operative imaging (CT, n = 37; MRI, n = 21; CT and MRI, n = 15] within 6 months of resection were included in this retrospective study. Qualitative imaging traits were assessed by 2 observers. A 3rd observer measured tumor apparent diffusion coefficient (ADC), enhancement ratios (ERs), and Haralick texture features. Blood biomarkers and imaging features were compared with histopathology (tumor grade and AJCC stage) and outcomes (TTR and OS) using log-rank, generalized Wilcoxon, Cox proportional hazards regression, and Fisher exact tests. RESULTS: Median TTR and OS were 53.9 and 79.7 months. ICC recurred in 64.4% (47/73) of patients and 46.6% (34/73) of patients died. There was fair accuracy for some qualitative imaging features in the prediction of worse tumor grade (maximal AUC of 0.68 for biliary obstruction on MRI, p = 0.032, observer 1) and higher AJCC stage (maximal AUC of 0.73 for biliary obstruction on CT, p = 0.002, observer 2; and AUC of 0.73 for vascular involvement on MRI, p = 0.01, observer 2). Cox proportional hazards regression analysis showed that CA 19-9 [hazard ratio (HR) 2.44/95% confidence interval (CI) 1.31-4.57/p = 0.005)] and tumor size on imaging (HR 1.13/95% CI 1.04-1.22/p = 0.003) were significant predictors of TTR, while CA 19-9 (HR 4.08/95% CI 1.75-9.56, p = 0.001) and presence of metastatic lymph nodes at histopathology (HR 2.86/95% CI 1.35-6.07/p = 0.006) were significant predictors of OS. On multivariable analysis, satellite lesions on CT (HR 2.79/95%CI 1.01-7.15/p = 0.032, observer 2), vascular involvement on MRI (HR 0.10/95% CI 0.01-0.85/p = 0.032, observer 1), and texture feature MRI variance (HR 0.55/95% CI 0.31-0.97, p = 0.040) predicted TTR once adjusted for the independent predictors CA 19-9 and tumor size on imaging. Several qualitative and quantitative features demonstrated associations with TTR, OS, and AJCC stage at univariable analysis (range: HR 0.35-19; p < 0.001-0.045), however none were predictive of OS at multivariable analysis when adjusted for CA 19-9 and metastatic lymph nodes (p > 0.088). CONCLUSIONS: There was reasonable accuracy in predicting tumor grade and higher AJCC stage in ICC utilizing certain qualitative and quantitative imaging traits. Serum CA 19-9, tumor size, presence of metastatic lymph nodes, and qualitative imaging traits of satellite lesions and vascular involvement are predictors of patient outcomes, along with a promising predictive ability of certain quantitative texture features.

Radical Prostatectomy Sociodemographic Disparities Based on Hospital and Physician Volume.

INTRODUCTION: The objective of this study was to assess the impact of volume status on socio-demographic disparities for radical prostatectomy (RP) in New York State. PATIENTS AND METHODS: All patients undergoing RP from 2006 to 2014 with an admitting or principal diagnosis of prostate cancer were identified. All 40,533 cases were separated into volume groups stratified by hospital and physician quartiles with a goal of maintaining consistent numbers between the 4 volume groups. Patient-level data included race, ethnicity, Charlson Comorbidity Index (CCI), median income by zip code, and source of payment. Hospital-level data included hospital location, teaching status, health service area, and facility number. Continuous and categorical variables were compared between cohorts using the Mann-Whitney-Wilcoxon test and Pearson χ2 tests, respectively. Multivariate regression analysis was conducted to assess predictors of access to very high-volume facilities and physician groups as well as predictors of receiving a minimally invasive RP. RESULTS: Of 40,533 total cases, 9602 (24%) were conducted at low-volume hospitals, 9208 (22%) were conducted at medium-volume hospitals, 8478 (21%) were conducted at high-volume hospitals, and 13,245 (33%) were conducted at very high-volume hospitals. Negative predictors of receiving care from a very high-volume physician include increased CCI, Asian race, black race, unknown race, Medicaid status, age 65 to 79 years, and age 80 to 130 years (P < .001). Negative predictors of receiving care from a very high-volume facility include Asian race, black race, unknown race, Medicaid status, and self-payment status (P < .001). CONCLUSION: Socioeconomic disparities exist in New York State for RP and are associated with disadvantaged groups being overrepresented in low-volume hospital and physician groups.

Fellowship and Subspecialization in Urology: An Analysis of Robotic-assisted Partial Nephrectomy.

OBJECTIVE: To evaluate the impact of a urologic fellowship on physician case-volume and immediate patient outcomes, and to assess predictors of undergoing a robotic-assisted partial nephrectomy by a fellowship-trained (FT) urologist. METHODS: We retrospectively reviewed all robotic (ICD-9 17.4) partial nephrectomies (PN; ICD-9 55.4) reported in the Statewide Planning and Research Cooperative Systems (SPARCS) database of New York State (NYS) from 2009 to 2014. Perioperative outcomes assessed included length of stay, 30-day readmission rates, 90-day readmission rates, and complication rates. Pearson chi-square tests were used to compare categorical variables, and unpaired Student t tests were used to assess continuous variables. RESULTS: FT urologists performed 2199 (56%) RAPN during the study period, and nonfellowship trained (NFT) urologists completed 1700 (44%) RAPN. FT urologists performed more RAPN in teaching hospitals than NFT urologists (23% vs 7%). The average surgical volume per year for a FT urologist conducting RAPN was 9.6 ± 2.2 cases/y. NFT urologists had an average surgical volume of 7.2 ± 1.5 cases/y (P = <.0001). No significant difference was found in length of stay, 30- or 90-day readmission rate, or complication rate between the groups. RAPN conducted at teaching hospitals were more likely to be conducted by FT urologists. Patients who were self-payers were less likely to have a RAPN by FT urologists. CONCLUSION: There were no differences for RAPN perioperative outcomes between FT urologists and their NFT peers. FT urologists perform a higher case-volume of RAPN in NYS, and this trend is increasing.

Long-term oncological and functional outcomes support use of low-dose-rate brachytherapy with or without external beam radiation in young men (≤60 years) with localized prostate cancer.

PURPOSE: To evaluate the oncological and functional outcomes of young men treated with low-dose-rate brachytherapy (BT) for prostate cancer (PCa). MATERIALS AND METHODS: 423 men aged ≤60 years with clinically localized PCa were treated with BT ± external beam radiation. Biochemical failure was defined by Phoenix criteria. Freedom from biochemical failure (FFbF) and cancer-specific survival (CSS) at 10 and 15 years were estimated by the Kaplan-Meier method with the log-rank test to compare outcomes between National Comprehensive Cancer Network risk groups. The Cox proportional hazards model was used to determine significant predictors for FFbF and CSS. RESULTS: Median followup was 9.9 years (range, 5.1-21.7). Median age was 57 years (range, 39-60), and median prostate-specific antigen was 6.1 ng/mL (range, 0.8-71). Overall, 10- and 15-year FFbF rates were 89% and 88%; 10- and 15-year CSS rates were 99% and 98%. Increasing disease risk was associated with lower FFbF and CSS (p < 0.0001). Biologically effective dose (p < 0.0001) and use of external beam radiation (p = 0.005) were significantly associated with higher FFbF. In men potent before BT, 64% (151/237) had preserved erectile function at a median 10.2 years. There was no significant difference between treatment groups with respect to long-term urinary function (p = 0.56). CONCLUSIONS: Younger men treated with BT experience excellent long-term PCa control with low rates of treatment-related toxicity.

Transgender Patient Care in Urology: Evaluation of Attitudes, Knowledge and Practice Patterns among Urologists in the New York Metropolitan Area.

INTRODUCTION: Transgender individuals suffer from significant health disparities, due in part to deficiencies in physician knowledge or comfort with addressing transgender health care needs. In this study we assessed the attitudes and clinical knowledge in caring for transgender patients of a representative sample of urologists in the New York metropolitan area. METHODS: An anonymous, online based questionnaire was sent to members of the New York Section of the American Urological Association. Statements evaluating knowledge and attitudes toward transgender care were scored on a 5-point Likert scale. RESULTS: A total of 92 providers (83.7% male) participated in the study, of whom 78.3% (72) have been in practice for at least 15 years. With respect to physician attitudes, there was a trend toward greater comfort with discussion of gender identity and counseling on gender confirmation surgery based on total number of transgender patients cared for during the course of their career. Regarding knowledge scores there were no significant associations with physician age, gender or years of practice. Despite the relatively weak self-reported fund of knowledge (2.64) and overall clinical competence (2.09), there was no overwhelming support to incorporate transgender care into urology training curricula (3.11). CONCLUSIONS: Despite growing education and awareness of transgender specific medical issues, many urologists self-report deficiencies in requisite knowledge and comfort in providing adequate, culturally competent care for transgender patients. Further work is needed to increase our collective comfort level with this new and evolving aspect of our field.

Trends in utilization and perioperative outcomes in live donor nephrectomies: a multi-surgical discipline analysis.

OBJECTIVE: We aim to analyze the trends in donor nephrectomy (DN) across three surgical disciplines-urology, general surgery, and transplant surgery, specifically to analyze the surgical techniques and perioperative outcomes. MATERIALS AND METHODS: We reviewed all live DN reported in the Statewide Planning and Research Cooperative System database of New York State (NYS) from 1995 to 2015. Surgeons were grouped in their respective disciplines using their state license number and the American Medical Association masterfile. We analyzed the volume of DN performed by each group along with how the surgical approach is, such as open, laparoscopic or robotic. Perioperative outcomes assessed were length of stay (LOS), 30-day and 90-day readmission rates, and complication rates RESULTS: A total of 6803 DN were performed with urologists, transplant surgeons and general surgeons accounting for 42%, 29%, and 29% of them, respectively. Urologists performed a higher case volume with a mean surgical volume of 17.4 ± 6.5 per year (p < 0.0001). During the study period, case volumes for urologists and transplant surgeons trended upward, while those for general surgeons trended downward. Urologists also utilized a minimally invasive surgery (MIS) such as laparoscopy or robotic approach in a higher percentage of their cases (p < 0.0001). Regarding perioperative outcomes, general surgeons had a higher mean LOS (p < 0.0001), while transplant surgeons had higher rates of 30-day and 90-day readmission rates (p < 0.0001). There were no statistically significant differences in complication rates following DN among the groups. CONCLUSION: Urologists remain vital members of the renal transplantation team as they perform a majority of DN in NYS and are increasingly achieving them via an MIS approach when compared to their general and transplant surgery counterparts. Perioperative outcomes are similar amongst all disciplines; however, general surgeons have higher mean LOS, while transplant surgeons have higher readmission rates.

Trifecta Outcomes to Assess Learning Curve of Robotic Partial Nephrectomy.

BACKGROUND AND OBJECTIVES: The learning curve for achieving desirable perioperative outcomes in robot-assisted partial nephrectomy (RAPN) has not been well studied. Information is available regarding "trifecta" outcomes of no complications, no positive margins, warm ischemia time (WIT) of ≤25 minutes, and a ≤15% decrease in postoperative glomerular filtration rate (GFR). This study was conducted to assess the impact of the learning curve on surgical outcomes in patients undergoing RAPN. METHODS: We reviewed 131 consecutive patients who underwent RAPN by a single, fellowship-trained surgeon from October 2007 through June 2015. Patients were divided into 4 subgroups, and mean perioperative values were compared. The learning curve was evaluated as the time it took the surgeon to attain a trifecta outcome. RESULTS: Means for the RENAL Nephrometry Score, procedure length, WIT, and estimated blood loss (EBL) were 5.3 ± 1.2, 172.1 ± 43.5 minutes, 22.7 ± 7.0 minutes, and 267.2 ± 341.8 mL, respectively. Significance was noted for differences in WIT (P = .50), postoperative creatinine (P = .006), postoperative estimated (e)GFR (P = .40), and percentage change in creatinine (P = .023). The learning curve for achieving positive outcomes was noted in >61-90 cases after 66-80 months of performing minimally invasive partial nephrectomy surgeries at a rate of 20 cases per year. CONCLUSION: RAPN is a safe, feasible procedure with slightly better surgical outcomes than laparoscopic partial nephrectomy (LPN). In the hands of an experienced surgeon, the learning curve for achieving trifecta outcomes can involve a significant number of cases over several years.

Minimally invasive adrenal surgery: virtue or vice?

Adrenocortical carcinoma (ACC) is a rare malignancy associated with poor prognosis despite available treatments. In patients with localized or locally advanced disease, complete resection with negative margins offers the only potential for cure. Unfortunately, most patients develop local and distant recurrence following initial resection highlighting the importance of meticulous surgical technique in the hands of an experienced surgeon. While minimally invasive surgery (MIS) has supplanted open surgery for small to medium-sized benign adrenal tumors, controversy surrounds the use of MIS for resection of ACC. We sought to provide an overview of the key oncological principles in the surgical management of ACC and to critically review the literature comparing outcomes between the open and MIS approaches.
