Patients with muscle invasive bladder cancer (MIBC) of variant histology have a poor prognosis. It is unclear if neoadjuvant chemotherapy prior to radical cystectomy is associated with pathological downstaging or improved overall survival (OS) for patients with variant histology. Our objective was to assess for associations between receipt of neoadjuvant chemotherapy, pathological downstaging and OS for patients with variant histology MIBC.Patients were identified in the National Cancer Database from 2004 to 2017 with MIBC, without metastases, who underwent radical cystectomy. Patients were stratified by histological subgroup, and receipt or nonreceipt of neoadjuvant chemotherapy. Pathological downstaging was defined as pT0N0 or pT ≤1N0, and OS from the time of diagnosis to date of death or censoring at last followup. Multivariable logistic regression analysis determined associations between neoadjuvant chemotherapy and pathological downstaging. Multivariable Cox regression analysis determined associations between neoadjuvant chemotherapy and OS.A total of 31,218 patients were included in the final study population (urothelial carcinoma [UC]: 27,779; sarcomatoid UC: 501; micropapillary UC: 418; squamous cell carcinoma: 1,141; neuroendocrine carcinoma: 629; adenocarcinoma: 750). Neoadjuvant chemotherapy was associated with pathological downstaging to pT0N0 in all histological subgroups (UC: OR 5.1 [4.6-5.6]; sarcomatoid UC: OR 13.8 [5.5-39.0]; micropapillary UC: OR 9.7 [2.8-46.8]; squamous cell carcinoma: OR 7.4 [2.1-24.5]; neuroendocrine: OR 4.7 [2.6-9.2]; adenocarcinoma: OR 23.3 [8.0-74.2]). Neoadjuvant chemotherapy was associated with improved OS for UC (HR 0.8 [0.77-0.84]), sarcomatoid UC (HR 0.64 [0.44-0.91]) and neuroendocrine carcinoma (HR 0.55 [0.43-0.70]).Neoadjuvant chemotherapy was associated with pathological downstaging for all MIBC histological variants, with improved OS for patients with UC, sarcomatoid variant UC and neuroendocrine carcinoma.

Background: Relative value units (RVUs) are the measure of value used in US Medicare reimbursement. Medicare determines physician work RVUs (wRVUs) from the Relative Value Update Committee (RUC) for a procedure based on operative time, technical skill and effort, mental effort and judgment, and stress. In theory, work RVUs should account for the complexity and operative time involved in a procedure. The aim of this study was to assess whether major procedures for treatment of benign prostatic enlargement (BPE) are fairly compensated based on complexity and operative time in the RVU system and compare them with the intended reimbursement. Methods: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database and the Centers for Medicare and Medicaid Services (CMS) Medicare Physician Fee Schedule were queried from 2015 to 2017. Single, current, procedural terminology codes associated with BPE treatments were included: transurethral resection of the prostate (TURP), photovaporization of the prostate (PVP), holmium laser enucleation of the prostate (HoLEP), retropubic simple prostatectomy (RSP), and suprapubic simple prostatectomy (SSP). The CMS operative times and the NSQIP real data were used in turn to calculate separate values for wRVUs per hour (wRVUs/hr) of operative time. The wRVUs/hr derived from CMS operative times represent RUC-estimated wRVUs/hr and wRVUs/hr derived from NSQIP represent actual wRVUs/hr. Results: A total of 27,664 cases were included from the NSQIP dataset. Median wRVU was 15.3 (interquartile range [IQR] 12.2-15.3), median operative time 50 minutes (IQR 33-74), and median wRVUs/hr 17.0 (IQR 11.6-26.2). RUC-estimated wRVUs/hr were TURP 12.2, PVP 12.2, RSP 9, SSP 9.3, and HoLEP 7.3. The actual wRVUs/hr were TURP 19.1, PVP 15.5, RSP 10.2, HoLEP 9.4, and SSP 7.6. Conclusions: Laser enucleation and simple prostatectomy are highly complex and efficacious procedures for treating BPE, yet the current payment schedule assigns these procedures the least amount of wRVUs/hr. Financial incentives for performing BPE surgeries are clearly misaligned.

Relative value units (RVUs) are the measure of value used in United States Medicare and Medicaid reimbursement. The Relative Update Committee (RUC) determines physician work RVU (wRVUs) based on operative time, technical skill and effort, mental effort and judgment, and stress. The primary aim of this study was to assess whether operative time is adequately accounted for in the wRVU system in pediatric urology.The American College of Surgeons National Surgical Quality Improvement Program Pediatric Participant User File (ACS-NSQIPP-PUF) was reviewed from 2012 to 2017. Most common single pediatric urology current procedural terminology (CPT) codes were included. The primary variable was wRVU per hour of operative time (wRVU/h). Linear regression analysis was used to assess the relative influence that operative time had on wRVU/h.25,432 cases were included in the final study population from 45 unique CPT codes. The median operative time was 79 min, and the median RVU/h was 12.2. Procedures with operative time less than 79 min had higher wRVU/h compared with procedures longer than 79 min (14.5 vs 10.5, p 0.001). Procedures with higher than average incidence of any complications had a lower wRVU/h (9.0 vs. 14.6 p 0.001). Linear regression analysis revealed that each additional hour of operative time was expected to decrease wRVU/h by 4.2 (-0.70 per 10 min, 95% CI: -0.71 to -0.69, p 0.001; RThis analysis of contemporary large pediatric population national-level data suggests that the wRVU system significantly favors shorter and less complex procedures in Pediatric Urology. Pediatric urologists performing longer and more complex procedures are not adequately compensated for the increase in complexity.Retrospective comparative study.

PURPOSE Daily aspirin use following cardiovascular intervention is commonplace and creates concern regarding bleeding risk in patients undergoing surgery. Despite its cardio-protective role, aspirin is often discontinued 5-7 days prior to major surgery due to bleeding concerns. Single institution studies have investigated perioperative outcomes of aspirin use in robotic partial nephrectomy (RPN). We sought to evaluate the outcomes of perioperative aspirin (pASA) use during RPN in a multicenter setting. MATERIALS AND METHODS We performed a retrospective evaluation of patients undergoing RPN at 5 high volume RPN institutions. We compared perioperative outcomes of patients taking pASA (81 mg) to those not on aspirin. We analyzed the association between pASA use and perioperative transfusion. RESULTS Of 1,565 patients undergoing RPN, 228 (14.5%) patients continued pASA and were older (62.8 vs 56.8 years, p

INTRODUCTION To evaluate the educational value of transplant rotation in urology residency. In the United States, exposure to kidney transplantation during urology residency has declined significantly over the past few decades. At our institution, transplantation has been a core component of urology residency since its inception in 1959.A 15-question anonymous survey was developed. The first 8 questions queried demographics and the last 7 were a set of questions with a Likert Scale response. The survey was electronic- mailed to past and current urology residents who had completed the transplant rotation, dating back to 1972.A total of 61 out of 98 (62%) individuals responded. The majority (59%) were general urologists, and one (2%) had completed a transplant fellowship. In their practices, 17% performed kidney transplants and 28% performed donor nephrectomies. Overall, 100% responded that the skills learned on the transplant rotation were beneficial for urology training, 100% had learned valuable vascular surgical techniques, and 93% felt that urology residents should have clinical transplant experience during their training. There was no statistical difference between the younger and older graduates in Likert scale responses.The majority of graduates did not perform transplants in their practice, yet, all of responders agreed that the skills learned on the transplant rotation were beneficial and 93% expressed that urology residents should have clinical transplant experience during residency. Kidney transplantation should be an integral part of urology residency training.

INTRODUCTION Perioperative stroke and myocardial infarction are uncommon but devastating thromboembolic complications. There is no comprehensive study detailing these complications for urologic procedures. The primary aim of this study is to determine which urologic procedures and patients carry the highest risk of perioperative stroke and myocardial infarction.The National Surgical Quality Improvement Program data set was reviewed from 2008-2017. Procedures coded under the urology specialty were included and patients who had a perioperative stroke or myocardial infarction were identified. CPTs were stratified into clinically relevant procedure groups. Two multivariable logistic regression analyses were performed to determine preoperative and procedural risk factors for developing perioperative stroke or myocardial infarction. A multivariable logistic regression analysis was performed to determine the association between these complications and 30-day mortality.A total of 281,744 cases were included, identifying 392 strokes (0.14%) and 1,016 myocardial infarctions (0.36%). Age ≥ 70, hypertension, and disseminated cancer were the strongest preoperative risk factors for perioperative stroke or myocardial infarction. Cystectomy was the highest risk urologic procedure (stroke: OR 3.3, 95%CI 2.3-4.8; MI: OR 7.2, 95%CI 5.6-9.1). Thirty-day mortality was dramatically worse for patients who had a perioperative stroke or myocardial infarction.Perioperative stroke and myocardial infarction were confirmed to be uncommon but devastating complications of urologic surgery, with incidence of 0.14% and 0.36%, respectively. Cystectomy was the highest risk urologic procedure. Perioperative stroke and myocardial infarction were strongly associated with age ≥ 70, hypertension, and disseminated cancer.

Key Points Question What is the comparative effectiveness of first-line targeted therapy, immunotherapy, and combination therapy in a real-world cohort of patients with metastatic clear cell renal cell carcinoma? Findings In this propensity-matched cohort study of 5872 patients treated in real-world clinical practice, first-line immunotherapy and combination therapy were associated with improved overall survival compared with first-line targeted therapy. Meaning This study suggests that clinical trial findings demonstrating an overall survival benefit associated with first-line immunotherapy-based regimens compared with targeted therapy are generalizable to a broader population of patients., Importance Clinical trials have shown an overall survival (OS) benefit associated with first-line immunotherapy (IT) and combination targeted therapy (TT) and IT regimens compared with TT among patients with metastatic clear cell renal cell carcinoma (RCC). Generalizability of these findings in a real-world cohort outside of a clinical trial setting is unclear. Objective To assess the association of first-line TT, IT, and combination TT and IT regimens with OS in a real-world cohort of patients with metastatic clear cell RCC. Design, Setting, and Participants This retrospective propensity-matched cohort study identified 5872 patients with metastatic clear cell RCC in the National Cancer Database from January 1, 2015, to December 31, 2017, who received first-line TT, IT, or combination TT and IT and were not treated on a clinical trial protocol. Patients were stratified by first-line systemic treatment. Statistical analysis was conducted from October 1 to December 1, 2020. Main Outcomes and Measures The primary outcome was OS from the date of diagnosis to death or censoring at last follow-up. After 1:1:1 nearest-neighbor caliper matching of propensity scores, survival analyses were conducted using Cox proportional hazards regression and Kaplan-Meier estimates. Results The final study population included 5872 patients (TT group: n = 4755 [81%]; 3332 men [70%]; median age, 64 years [interquartile range, 57-71 years]; IT group: n = 638 [11%]; 475 men [74%]; median age, 61 years [interquartile range, 54-69 years]; and combination TT and IT group: n = 479 [8%]; 321 men [67%]; median age, 62 years [interquartile range, 55-69 years]), and the matched cohort included 1437 patients (479 per treatment group). Patients in the IT and combination TT and IT groups were younger than those in the TT group, had fewer comorbid conditions (Charlson-Deyo score of 0, 480 of 638 [75%] in the TT group, 356 of 479 [74%] in the IT group, and 3273 of 4755 [69%] in the combination TT and IT group), and were more often treated at academic centers (315 of 638 [49%], 216 of 479 [45%], and 1935 of 4755 [41%], respectively). Both first-line IT and combination TT and IT were associated with improved OS compared with first-line TT for patients with metastatic clear cell RCC (IT group: hazard ratio [HR], 0.60 [95% CI, 0.48-0.75]; P, This cohort study assesses the association of first-line targeted therapy, immunotherapy, and combination targeted therapy and immunotherapy regimens with overall survival in a real-world cohort of patients with metastatic clear cell renal cell carcinoma (ccRCC).

Clinical trials have not shown a significant overall survival (OS) difference between chemotherapy and immunotherapy as first-line agents in metastatic urothelial carcinoma (UC). However, the generalizability of these findings in a real-world setting has not yet been evaluated in comparative effectiveness studies.To assess the effectiveness of first-line immunotherapy compared with chemotherapy regimens on OS in patients with metastatic UC of the bladder.This retrospective propensity-matched study identified metastatic bladder UC patients in the National Cancer Database from 2014 to 2017 who received either first-line immunotherapy-monotherapy or multi-agent chemotherapy, and who were not treated on a clinical trial protocol.The primary outcome was OS from the date of diagnosis to date of death or censoring at last follow-up. Patients were stratified into first-line immunotherapy and chemotherapy treatment groups. After 1:1 nearest-neighbor caliper-matching of propensity scores, the survival analysis was conducted using Cox regression modeling and Kaplan-Meier estimates.A total of 2,796 patients were included in the final study population, and 960 in the matched cohort (480 per treatment group). Utilization of immunotherapy increased over the time period studied as chemotherapy decreased (Immunotherapy: 3%-37%; Chemotherapy: 97%-63%; P0.001). In the overall cohort, patients who received first-line immunotherapy were older and more comorbid than those who received first-line chemotherapy (Age: 73 v. 67, respectively, P0.001; Charlson-Deyo score ≥2: 17% v. 11.5%, respectively, P0.001). In the matched cohort, patients who were treated with first-line immunotherapy had similar OS to those who were treated with first-line chemotherapy (HR: 0.91, 95CI 0.72-1.15). Due to the retrospective nature of the study, interpretation is limited by potential selection bias from unmeasured confounding.Metastatic bladder UC patients who received first-line immunotherapy had similar OS to those who received first-line chemotherapy.

In 2017 United Network for Organ Sharing (UNOS) implemented a simultaneous liver kidney transplant (SLK) allocation policy. Our institution uses a more restrictive criteria for SLK; thus, we have a group of patients that would have qualified for SLK under the new allocation policy but received liver transplantation alone (LTA). We compared survival and post-operative renal function in patients that received LTA stratified by whether they met the new UNOS SLK criteria. There was no difference in graft and patient survival. The majority (95%) of LTA patients meeting the UNOS SLK criteria did not need dialysis at one year, with a mean eGFR increase from 23mL/min preoperatively to 48mL/min at one year. Of those with eGFR ≤ 20mL/min at one month after surgery, the majority did regain adequate renal function. The implementation of the UNOS SLK allocation policy was appropriate in the previously unregulated area. This policy provides an excellent framework for those that may benefit from SLK. Our data suggests that a more restrictive policy may be possible in order to promote the best use of donated organs. The current safety net is appropriately positioned to capture patients in need of subsequent kidney transplant.

Physician work relative value units are determined based on operative time, technical skill, mental effort and stress. In theory, work relative value units should account for the operative time involved in a procedure, resulting in similar work relative value units per unit time for short and long procedures. We assessed whether operative time is adequately accounted for by the current work relative value units assignments.The American College of Surgeons National Surgical Quality Improvement Program database was reviewed from 2015 to 2017. The 50 most frequently coded urology CPT codes were included in the study. The primary variable was work relative value units per hour of operative time (work relative value units per hour). Linear regression analysis was used to assess the associations between work relative value units, operative time and the work relative value units per hour variable.A total of 105,931 cases were included in the study. Among the included urology CPTs the median work relative value units was 15.26, median operative time was 48 minutes and median work relative value units per hour was 11.2. CPTs with operative time less than 90 minutes had higher work relative value units per hour compared with longer procedures (12.2 vs 8.7, p0.001). Univariable analysis revealed that each additional hour of operative time was associated with a decrease in work relative value units per hour by 1.32 (-0.022 per minute, 95% CI -0.037 - -0.001, p0.001) and that work relative value units were not statistically associated with work relative value units per hour (-0.093, 95% CI -0.193 - 0.007, p=0.07).This analysis of large population, national level data suggests that the current work relative value units assignments do not proportionally compensate for longer operative times.

Relative value units (RVU) are the measure of value used in United States Medicare and Medicaid reimbursement. The Relative Update Committee (RUC) determine physician work RVU (wRVU) based on operative time, technical skill and effort, mental effort and judgement, and stress. In theory, wRVU should account for the complexity and operative time involved in a procedure.The primary aim of this study is to assess if operative time and complexity of hypospadias surgery is adequately accounted for by the current wRVU assignments.The American College of Surgeons National Surgical Quality Improvement Program Participant User File (ACS-NSQIP PUF) database was utilized from 2012 to 2017. Single stage hypospadias current procedural terminology (CPT) codes (including acceptable secondary CPT codes) were extracted. Using total wRVU and total operative time, the primary variable of wRVU per hour was calculated (wRVU/hr). Multivariable linear regression analysis was used to assess the relative influence that wRVU and operative time had on the wRVU/hr variable.9810 cases were included in the final study population divided into four categories: simple distal (eg. MAGPI, V-Flap), single stage distal, single stage mid, single stage proximal. On analysis of variance, there was statistically significant different wRVU/hr for the four different types of hypospadias repairs with simple distal having the highest mean wRVU/hr of 19.5 and the lowest being proximal hypospadias repairs at 13.2. Simple distal, distal and midshaft hypospadias had statistically significantly higher wRVU/hr compared to proximal hypospadias (16.2, 95% CI: 15.8-16.5 vs. 13.2, 95% CI 10.9-15.5; p0.001). Multivariable linear regression revealed that each additional hour of operative time was expected to decrease wRVU/hr by 10.5 (-10.5, 95% CI: -11.0 to -10.1, p 0.001); total work wRVU had a statistically significant independent association with wRVU/hr (0.6, 95%CI: 0.5-0.7, p0.001).This the first objective assessment of the current wRVU assignments with regards to one stage hypospadias repairs. More complex and longer hypospadias procedures are not adequately compensated by wRVU. Most notably, simple distal procedures are reimbursed at a mean of 19.5 wRVU/hr compared to 13.2 wRVU/hr for one stage proximal repairs.This analysis of national-level data suggests that the current wRVU assignments significantly favor shorter and simpler procedures in hypospadias surgery.

Summary Introduction Improved survivorship after treatment of pediatric malignancies has dramatically increased, while pre-treatment fertility preservation in this population has not kept pace. New guidelines emphasize fertility preservation in young adolescents, but the impact of these guidelines is unknown. Objectives We sought to evaluate the rate of fertility preservation among at-risk adolescents diagnosed with cancer at our institution, as well as evaluate barriers to fertility preservation. Design We performed an IRB-approved historical cohort study of adolescent males 13 years and older evaluated in the Pediatric Hematology-Oncology clinic at Doernbecher Children's Hospital from 2010 to 2018. Electronic chart review was used assess discussion of fertility preservation and barrier to successful preservation in boys with a new diagnosis of cancer who received systemic chemotherapy and/or gonadal or pelvic irradiation. Results 82 boys were included in the study. Forty-two (51%) received counselling about fertility preservation, and of those 29 (70%) successfully banked sperm. Neither counseling for fertility preservation nor success at sperm banking differed by patient age, but both differed by malignancy. Patients with Hodgkin's lymphoma had the highest rate of counselling, while those with leukemia had the lowest. Acute illness as a barrier to preservation was found in 40% of those who did not receive counselling. Discussion Our study demonstrates a stagnant rate of fertility counseling and preservation despite increased advocacy. The retrospective nature of our study limited our ability to assess the counselling that occurred, and the lack of granular race data limited study of the implicit selection bias that may be involved in such counseling. As more institutions move toward a multi-disciplinary care model, we believe that pediatric urologists or fertility specialists must play a vocal role in the care of these at-risk adolescents. Conclusion Despite increasing advocacy for fertility preservation, our data shows no significant change in previously reported trends. Patients with Hodgkin's lymphoma have a higher rate of counseling and cryopreservation in comparison to those with other malignancies.

Summary Introduction There are no large multi-institutional studies reporting on perioperative complications of hypospadias repairs. We sought to determine perioperative complications of hypospadias repairs from the National Surgical Quality Improvement Program Pediatrics (NSQIP-P) to aid in patient counseling. Study design This cohort study from 2012 to 2017 was conducted using NSQIP-P database. Pediatric patients undergoing hypospadias surgery were identified and compared based on 4 major categories: distal/midshaft repair, one-stage repair proximal, stage one repair, and stage two repair. Baseline demographics between the four groups and perioperative parameters were compared. Multivariable logistic regression analysis models including type of repair was used to determine associations with overall complications, infectious complications, and dehiscence. Discussion There were 11,292 patients identified in the study population. Overall, 78% underwent distal/midshaft hypospadias repair, 12% underwent one-stage proximal repair, 1.4% underwent proximal first stage repair and 9% underwent proximal second stage repair. Multivariable logistic regression analysis revealed that proximal first stage procedures had similar overall complications to distal/mid repairs but proximal one-stage and proximal second stage procedures were associated with significantly more overall complications, local infectious complications, and dehiscence. Age, race, operative time, prematurity were also independently associated with increased overall complications. As expected, complication rates are higher in those with proximal hypospadias. In staged hypospadias, first stage has a lower complication rate compared to second stage. All complications, especially of infectious and dehiscence are the highest in the one-stage proximal and proximal second stage repairs. Conclusion We report large multi-institutional analysis of 30-day peri-operative hypospadias repair complications; this information is useful for patient counseling and education. Summary Table .

To characterize spermatogenesis in the estrogenized transgender patient.This is a retrospective, single-center, cross-sectional study. Seventy-two transgender women underwent gender-affirming orchiectomy between May 2015 and January 2017. All were on long-term (1 year) cross-sex hormonal therapy prior to orchiectomy. Patient data were obtained via chart review. Histologic analysis was performed by a pathology resident under the supervision of a genitourinary pathologist. The main outcome is histologic presence of germ cells and presence of spermatids (a proxy for preserved spermatogenesis) in orchiectomy specimens.There were 141 pathologic specimens available for analysis. Germ cells were present in 114 out of 141 (81%) testicles. Spermatids were present in 57 (40%) testicles. Presence of germ cells was associated with older age (43 vs 35 years, P = .007) and increased testicular weight (28.6 g vs 19.3 g, P.001). Presence of spermatids was associated with increased weight (31.5 g vs 23.3 g, P.001) and volume (20.3 mL vs 12.6 mL, P.001). There was a linear correlation between testis volume and preserved spermatogenesis (Pearson's r = 0.448, P.001).Despite long-term hormone therapy, the majority (80%) of transgender women have germ cells present in the testicle. Spermatogenesis is preserved in approximately 40% of these individuals. Duration of hormonal therapy did not affect the degree of preservation of germ cells or spermatogenesis but starting hormonal treatment at a younger age may be associated with decreased germ cells in the testicle. Volume of testicles predict presence of preserved spermatogenesis.

Summary Introduction Undescended testis (UDT) is one of the most common congenital disorders and is associated with infertility and testicular cancer. Multiple guidelines internationally have recommended orchiopexy by 18 months. Multiple large retrospective studies published in the last decade have found persistent delay in timing of orchiopexy. Objective The aim of the study was to determine timing at which UDTs are referred at the tertiary pediatric hospital and assess factors that are associated with delay in UDT referral. Study design Based on clinical observations and previous data, a series of clinical and socio-economic variables were constructed to design a prospective database. All patients who underwent orchiopexy for UDT from March 1, 2017, to August 31, 2018, were reviewed for demographic and clinical data. Referral appointments after 18 months were considered delayed. Factors associated with delay in UDT referral were analyzed using univariate and multivariate analysis with logistic regression. Results One hundred seventy-eight patients underwent orchiopexy for UDT. The median age was 44 months, and 64% of them had delay in referral. On univariate analysis, normal birth testicular examination, diagnosis of ‘retractile testicle,’ long gap without seeing pediatrician, diagnosis by a new physician, and primary language non-English were associated with delayed UDT referral. On multivariate analysis, delayed referral was associated with normal testicular examination at birth, history of ‘retractile testis,’ diagnosis not by the regular primary care provider, and other health or social issues that may have led to delay. Discussion This is the first prospective study analyzing timing of referral for boys with cryptorchidism. It was found that timing of treatment of UDT with orchiopexy has not improved over the last decade. Major causes in delay in referral may be due to poor of education of families and lack of routine testicular examinations by referring providers. Secondary ascent may account a significant number of delayed orchiopexy cases. Conclusion Most patients at Doernbecher had delayed referral of cryptorchidism. Factors associated with delay were determined. To improve treatment of cryptorchidism, quality-based interventions and the importance of education and routine testicular examinations need to be focused on.
