RESUMO
BACKGROUND: Stage III renal cell carcinoma (RCC) encompasses both lymph node-positive (pT1-3N1M0) and lymph node-negative (pT3N0M0) disease. However, prior institutional studies have indicated that among patients with stage III disease, those with lymph node disease have worse oncologic outcomes and experience survival that is similar to that of patients with American Joint Committee on Cancer (AJCC) stage IV disease. The objective of the current study was to validate these findings using a large, nationally representative sample of patients with kidney cancer. METHODS: Patients with AJCC stage III or stage IV RCC were identified using the National Cancer Data Base (NCDB). Patients were categorized as having lymph node-positive stage III (pT1-3N1M0), lymph node-negative stage III (pT3N0M0), or stage IV metastatic (pT1-3 N0M1) disease. Cox proportional hazards models compared outcomes while adjusting for comorbidities. Kaplan-Meier estimates illustrated relative survival when comparing staging groups. RESULTS: A total of 8988 patients met the inclusion criteria, with 6587 patients classified as having lymph node-negative stage III disease, 2218 as having lymph node-positive stage III disease, and 183 as having stage IV disease. Superior survival was noted among patients with lymph node-negative stage III disease, but similar survival was noted between patients with lymph node-positive stage III and stage IV RCC, with 5-year survival rates of 61.9% (95% confidence interval [95% CI], 60.3%-63.4%), 22.7% (95% CI, 20.6%-24.9%), and 15.6% (95% CI, 11.1%-23.8%), respectively. CONCLUSIONS: Current RCC staging systems group pT1-3N1M0 and pT3N0M0 disease as stage III disease. However, the results of the current validation study suggest the need for further stratification and even placement of patients with pT1-3N1M0 disease into the stage IV category. Staging that accurately reflects oncologic prognosis may help clinicians better counsel and select patients who might derive the most benefit from lymphadenectomy, adjuvant systemic therapy, more rigorous imaging surveillance, and clinical trial participation.

INTRODUCTION: To evaluate flexible pediatric cystoscopy (FPC) as an adjunctive procedure to retrograde urethrography (RUG) and voiding cystourethrography (VCUG) in the preoperative setting for male urethral strictures. Since imaging interpretation of stricture length and caliber can be difficult at times, we sought to evaluate diagnostic utility of FPC to predict reconstructive surgery. MATERIALS AND METHODS: Reconstructive urology databases at Washington University and Columbia University were queried from 2010-2017. A total of 185 anterior urethroplasty patients met inclusion criteria. All surgeries were performed by a single surgeon. There were 102 patients that underwent preoperative FPC (7.5 Fr in diameter). Surgical urethroplasty techniques employed were: ventral or dorsal onlay buccal mucosa graft, fasciocutaneous penile skin flap, excision and primary anastomosis or augmented anastomotic. We analyzed the RUG, VCUG, FPC, and intraoperative details of the urethral strictures by univariate and multivariate statistics. RESULTS: Mean patient age was 47.2 (+/-16.5) years. Of the patients who underwent FPC, 42.2% were narrower than the FPC, and 57.8% were wider. Intraoperative stricture length better correlated with FPC findings compared to RUG/ VCUG (r = 0.834 versus r = 0.766) (p < 0.001). Moreover, inability to pass the FPC through the stricture correlated with the need to perform urethral stricture excision or complete reconstruction of the urethral plate (p = 0.005), rather than onlay urethroplasty. CONCLUSION: Preoperative FPC is a useful adjunctive tool in the evaluation of urethral strictures. FPC facilitates stricture assessment by accurately correlating with intraoperative stricture length and predicting the need to excise or graft during reconstruction.

BACKGROUND: Men with locally advanced prostate cancer (LAPCa) or regionally advanced prostate cancer (RAPCa) are at high risk for death from their disease. Clinical guidelines support multimodal approaches, which include radical prostatectomy (RP) followed by radiotherapy (XRT) and XRT plus androgen deprivation therapy (ADT). However, there are limited data comparing these substantially different treatment approaches. Using Surveillance, Epidemiology, and End Results (SEER)-Medicare data, this study compared survival outcomes and adverse effects associated with RP plus XRT versus XRT plus ADT in these men. METHODS: SEER-Medicare data were queried for men with cT3-T4N0M0 (LAPCa) or cT3-T4N1M0 (RAPCa) prostate cancer. Propensity score methods were used to balance cohort characteristics between the treatment arms. Survival analyses were analyzed with the Kaplan-Meier method and Cox proportional hazards models. RESULTS: From 1992 to 2009, 13,856 men (≥65 years old) were diagnosed with LAPCa or RAPCa: 6.1% received RP plus XRT, and 23.6% received XRT plus ADT. At a median follow-up of 14.6 years, there were 2189 deaths in the cohort, of which 702 were secondary to prostate cancer. Regardless of the tumor stage or the Gleason score, the adjusted 10-year prostate cancer-specific survival and 10-year overall survival favored men who underwent RP plus XRT over men who underwent XRT plus ADT. However, RP plus XRT versus XRT plus ADT was associated with higher rates of erectile dysfunction (28% vs 20%; P = .0212) and urinary incontinence (49% vs 19%; P < .001). CONCLUSIONS: Men with LAPCa or RAPCa treated initially with RP plus XRT had a lower risk of prostate cancer-specific death and improved overall survival in comparison with those men treated with XRT plus ADT, but they experienced higher rates of erectile dysfunction and urinary incontinence.

PURPOSE: We performed a network meta-analysis of available randomized, controlled trials to elucidate the risks of urinary tract infection associated with transurethral catheterization, suprapubic tubes and intermittent catheterization in the postoperative setting. MATERIALS AND METHODS: PubMed®, EMBASE® and Google Scholar™ searches were performed for eligible randomized, controlled trials from January 1980 to July 2015 that included patients who underwent transurethral catheterization, suprapubic tube placement or intermittent catheterization at the time of surgery and catheterization lasting up to postoperative day 30. The primary outcome of comparison was the urinary tract infection rate via a network meta-analysis with random effects model using the netmeta package in R 3.2 (www.r-project.org/). RESULTS: Included in analysis were 14 randomized, controlled trials in a total of 1,391 patients. Intermittent catheterization and suprapubic tubes showed no evidence of decreased urinary tract infection rates compared to transurethral catheterization. Suprapubic tubes and intermittent catheterization had comparable urinary tract infection rates (OR 0.903, 95% CI 0.479-2.555). On subgroup analysis of 10 randomized, controlled trials with available mean catheterization duration data in a total of 928 patients intermittent catheterization and suprapubic tube were associated with significantly decreased risk of urinary tract infection compared to transurethral catheterization when catheterization duration was greater than 5 days (OR 0.173, 95% CI 0.073-0.412 and OR 0.142, 95% CI 0.073-0.276, respectively). CONCLUSIONS: Transurethral catheterization is not associated with an increased urinary tract infection risk compared to suprapubic tubes and intermittent catheterization if catheterization duration is 5 days or less. However, a suprapubic tube or intermittent catheterization is associated with a lower rate of urinary tract infection if longer term catheterization is expected in the postoperative period.

BACKGROUND: The role of retroperitoneal lymph node dissection (RPLND) as first-line treatment for testicular seminoma is less well defined than for testicular nonseminomatous germ-cell tumors. We describe utilization of primary RPLND in the United States and report on overall survival (OS) after surgery for these men. PATIENTS AND METHODS: Using 2004-2014 data from the National Cancer Data Base, we identified 62,727 men with primary testicular cancer, 31,068 of whom were diagnosed as having seminoma. After excluding men with benign, non-germ cell, and nonseminomatous germ-cell tumor histologies, those who did not undergo RPLND, those where clinical stage and survival data were unavailable, and those with testicular seminoma who underwent RPLND in the postchemotherapy setting (n = 47), 365 men comprised our final cohort. Descriptive statistics were used to summarize clinical and demographic factors. The Kaplan-Meier method was used to determine OS. RESULTS: A total of 365 men with testicular seminoma underwent primary RPLND. At a median follow-up of 4.1 years, there were 16 deaths in the entire cohort. Five-year OS was 94.2%. Subset analysis of men with stage I and IIA/B disease who underwent primary RPLND revealed 5-year OS rates of 97.3% and 92.0%, respectively (P = .035). OS did not significantly differ in patients with stage IIA versus IIB disease (91.8% vs. 92.3%, respectively, P = .907). CONCLUSION: Although RPLND is rarely used as primary therapy in testicular seminoma, OS rates appear to be comparable to rates reported in the literature for primary chemotherapy or radiotherapy. Ongoing prospective trials will clarify the role of RPLND in the management of testicular seminoma.

PURPOSE: To identify factors associated with receipt of partial nephrectomy (PN) and minimally invasive surgery (MIS) in patients with clinical T1 renal cell carcinoma (RCC) using the National Cancer Data Base (NCDB). METHODS: We queried the NCDB from 2010 to 2014 identifying patients treated surgically for cT1a-bN0M0 RCC. Logistic regression was used to examine associations between socioeconomic, clinical, and treatment factors, and receipt of MIS or PN within the T1 patient population. RESULTS: Our cohort included 69,694 patients (cT1a, n = 44,043; cT1b, n = 25,651). For cT1a tumors, 70% of patients received PN and 65% underwent MIS. For cT1b tumors, 32% of patients received PN and 62% underwent MIS. cT1a and cT1b patients with household income < $62,000, without private insurance, and treated outside academic centers were less likely to receive MIS or PN. cT1a patients traveling > 31 miles were more likely to undergo MIS. For both cT1a/b, the farther a patient traveled for treatment, the more likely a PN was performed. CONCLUSION: Data showed an increase in utilization of MIS and PN from 2010 to 2014. However, patients in the lowest socioeconomic groups were less likely to travel and were more likely to receive more invasive treatments. On the basis of these findings, additional research is needed into how regionalization of RCC surgery affects treatment disparities.

Web-based physician ratings are increasingly popular but imperfect proxies for clinical competence. Yet they provide valuable information to patients and providers when taken in proper context. Providers need to embrace the reviews and use them to enact positive change in order to improve the quality of our patients' experience. Patients need to realize the limitations of online ratings, particularly with smaller sample size and be discerning about the reasons behind the review.
RESUMO
Paragangliomas are rare neuroendocrine tumors with 500 to 1600 new cases in the United States each year (1). The clinical presentation may range from asymptomatic to the classic triad of episodic diaphoresis, headache, and palpitations. Surgery is the hallmark of treatment when tumors are amenable to resection. When patients are found to have metastases, systemic therapies may be employed. In this case report, we present a patient found to have a large retroperitoneal paraganglioma with nodal metastases.
RESUMO
OBJECTIVE: To understand the urology Match process from the perspective of residency program directors, with a particular focus on the role of postinterview communication. Recent surveys of urology applicants revealed that postinterview communication from programs often violates the rules of the American Urological Association Urology Residency Matching Program (the "Match"), and that such communication may influence applicant rank lists. METHODS: An anonymous, electronic survey seeking information regarding postinterview communication during the Match was sent to all program directors of urology residency programs participating in the 2017 AUA Match cycle. RESULTS: Of 138 surveys sent, 84 were completed for a 61% response rate. Among respondents, 97.6% percent of programs received postinterview communication from applicants, 76.2% of programs received an informal commitment from an applicant, and 38.3% failed to match an applicant who made an informal commitment. Most program directors (81.7%) responded that promises by applicants did not influence their rank list, and 57.1% state that participating in a second look does not have the potential to influence an applicant's rank order. Cumulatively, 76.2% of program directors felt that it was appropriate for applicants to cancel an interview if they provided 2 or more weeks' notice. CONCLUSION: The current study suggests that urology program directors do not ascribe significant value to continued contact with applicants after the interview, regardless of whether such contact is in the form of postinterview communication or in the form of second-look visits.

OBJECTIVE: Alvimopan use has reduced the length of hospital stay in patients undergoing major abdominal surgeries and radical cystectomy. Retroperitoneal lymph node dissection for testicular cancer may be associated with delayed gastrointestinal recovery prolonging hospital length of stay. We evaluate whether alvimopan is associated with enhanced gastrointestinal recovery and shorter hospital length of stay in men undergoing retroperitoneal lymph node dissection for testicular cancer. MATERIALS AND METHODS: From 2010 to 2016, 29 patients underwent open, transperitoneal bilateral template retroperitoneal lymph node dissection. Data for patients who received alvimopan were prospectively collected and compared to a historical cohort of patients who did not receive alvimopan. Primary outcome measures were length of stay and recovery of gastrointestinal function. Descriptive statistics were reported. Time-to-event outcomes were evaluated using cumulative incidence curves and log rank test. Factors associated with length of stay were analyzed for correlation using multiple linear regression. RESULTS: Of 29 men undergoing retroperitoneal lymph node dissection, eight received alvimopan and 21 did not. The two cohorts were well matched, with no significant differences. In the alvimopan cohort compared with those who did not receive alvimopan median time to return of flatus was 2 versus 4 days (p=0.0002), and median time to first bowel movement was 2.5 versus 5 days (p=0.046), respectively. Median length of stay in the alvimopan cohort was 4 days versus 6 days in those who did not receive alvimopan (p=0.074). In adjusted analyses, receipt of alvimopan did not influence length of stay. CONCLUSION: Alvimopan may facilitate gastrointestinal recovery after retroperitoneal lymph node dissection for testicular cancer. Whether this translates into reduced length of stay needs to be determined by randomized controlled trials using larger cohorts. LEVEL OF EVIDENCE: 3b.
RESUMO
INTRODUCTION: The benefit of lymph node dissection (LND) in renal cell carcinoma (RCC) remains poorly defined. Despite this uncertainty, the American Urological Association (AUA) guideline on localized renal cancer recommends that LND be performed for staging purposes when there is suspicion of regional lymphadenopathy on imaging. Using the National Cancer Database (NCDB), we sought to determine how much of a departure the new AUA guideline is from current practice. We hypothesized that practice patterns would reflect the "Expert Opinion" recommendation and that patients who are clinical lymph node (cLN) positive would receive a LND more often than those who are cLN negative. Additionally, we sought to determine factors that would trigger a LND as well the accuracy of clinical staging by examining the relationship between cLN and pathologic lymph node (pLN) status of patients who received a LND. MATERIALS AND METHODS: The NCDB was queried for patients with nonmetastatic RCC who underwent partial nephrectomy or nephrectomy from 2010 to 2014. Patient sociodemographic and clinical characteristics were extracted. Frequency distributions were calculated for patients with both cLN and pLN status available. Of patients who received a LND, sensitivity, specificity, and positive/negative predictive values (PPV/NPV) of cLN status for pLN positivity were calculated. Logistic regression models were used to examine association between clinical and socioeconomic factors and receipt of LND. Propensity score matching was used in sensitivity analyses to examine potential for reporting bias in NCDB data. RESULTS: We identified 110,963 patients who underwent surgery for RCC, of whom 11,867 (11%) had LND performed at the time of surgery. cLN and pLN information were available in 11,300 patients, of which 1,725 were preoperatively staged as having positive cLN. More LNDs were performed per year for patients who were cLN negative than cLN positive. Of patients who received a LND, the majority of patients were cLN negative across all clinical T (cT) stages. Multivariable analysis showed that all patients who had care at an academic/research institution (odds ratio [OR]: 1.58, 95% confidence interval [CI]: 1.43-1.74) and had to travel >12.5 to 31.0 miles and >31.0 miles to a treatment center (OR: 1.08, 95%CI: 1.01-1.15 and OR: 1.28, 95%CI: 1.20-1.36, respectively) were more likely to get a LND. As cT stage increased from cT2-4, the risk of LND increased (OR range: 4.7-7.90, respectively). Patients who were cLN positive were more likely to receive a LND at the time of surgery (OR: 18.68, 95%CI: 16.62-21.00). Of the patients who received a LND, clinical staging was more specific than sensitive. CONCLUSION: More patients received a LND who were cLN negative compared to patients who were cLN positive. Patients who were cLN positive were more likely to receive a LND. Treatment center type, distance to treatment center, cT stage, and cLN positivity were factors associated with LND receipt.

Postprostatectomy urinary incontinence has a significant impact on the quality of life of patients who undergo radical prostatectomy. Stress and overflow incontinence may result from the procedure, with sphincteric incompetence and detrusor hypocontractility implicating their development, respectively. In many cases, treatment begins with conservative approaches, including pelvic floor muscle training or biofeedback. Pharmacotherapy can be used to treat overactive bladder. For stress incontinence, transurethral bulking agents are utilized in select patients; however, artificial urinary sphincter and male slings are the most efficacious options with good success rates. In this review, the various treatment modalities are critically discussed with special emphasis on safety and efficacy.

OBJECTIVE: To evaluate the effect of conservative management of high-grade renal trauma on length of hospitalization, we aim to describe characteristics of patients with high-grade renal trauma that are associated with an increased length of stay (LOS) and the effect of conservative vs surgical management on hospital LOS. METHODS: A retrospective review of all patients who suffered unilateral high-grade renal trauma (grade 3 or higher) from September 1977 to August 2012 at San Francisco General Hospital in San Francisco, CA was performed. Patients' demographic information, mechanism of injury, injury grade, data about associated injuries, hospital LOS, and management were collected. Descriptive analysis was performed using chi-square, ordered logistic regression, and linear regression analysis. Multivariable analysis was performed using a Fine-Gray model of competing risks survival analysis, adjusting for trauma type, grade, surgery, associated injury, and complications. RESULTS: The cohort consisted of 408 patients with high-grade unilateral renal trauma of which 257 patients underwent renal exploration. The adjusted multivariable analysis revealed that trauma type, injury grades, nongenitourinary surgery, associated injuries, and complications were associated with increased hospital LOS (P <.01 for all). Renal exploration compared to conservative management for high-grade renal trauma was not associated with an increased hospital LOS (P = .10). CONCLUSION: There is no significant difference between conservative and surgical management of high-grade renal trauma in terms of hospital LOS. Conservative management of high-grade renal trauma does not impact patients' length of hospitalization.
