Background Open radical cystectomy (ORC) and urinary diversion in patients with bladder cancer (BCa) are associated with significant perioperative complication risk. Objective To compare perioperative complications between robot-assisted radical cystectomy (RARC) and ORC techniques. Design, setting, and participants A prospective randomized controlled trial was conducted during 2010 and 2013 in BCa patients scheduled for definitive treatment by radical cystectomy (RC), pelvic lymph node dissection (PLND), and urinary diversion. Patients were randomized to ORC/PLND or RARC/PLND, both with open urinary diversion. Patients were followed for 90 d postoperatively. Intervention Standard ORC or RARC with PLND; all urinary diversions were performed via an open approach. Outcome measurements and statistical analysis Primary outcomes were overall 90-d grade 2–5 complications defined by a modified Clavien system. Secondary outcomes included comparison of high-grade complications, estimated blood loss, operative time, pathologic outcomes, 3- and 6-mo patient-reported quality-of-life (QOL) outcomes, and total operative room and inpatient costs. Differences in binary outcomes were assessed with the chi-square test, with differences in continuous outcomes assessed by analysis of covariance with randomization group as covariate and, for QOL end points, baseline score. Results and limitations The trial enrolled 124 patients, of whom 118 were randomized and underwent RC/PLND. Sixty were randomized to RARC and 58 to ORC. At 90 d, grade 2–5 complications were observed in 62% and 66% of RARC and ORC patients, respectively (95% confidence interval for difference, −21% to −13%; p = 0.7). The similar rates of grade 2–5 complications at our mandated interim analysis met futility criteria; thus, early closure of the trial occurred. The RARC group had lower mean intraoperative blood loss (p = 0.027) but significantly longer operative time than the ORC group (p < 0.001). Pathologic variables including positive surgical margins and lymph node yields were similar. Mean hospital stay was 8 d in both arms (standard deviation, 3 and 5 d, respectively; p = 0.5). Three- and 6-mo QOL outcomes were similar between arms. Cost analysis demonstrated an advantage to ORC compared with RARC. A limitation is the setting at a single high-volume, referral center; our findings may not be generalizable to all settings. Conclusions This trial failed to identify a large advantage for robot-assisted techniques over standard open surgery for patients undergoing RC/PLND and urinary diversion. Similar 90-d complication rates, hospital stay, pathologic outcomes, and 3- and 6-mo QOL outcomes were observed regardless of surgical technique. Patient summary Of 118 patients with bladder cancer who underwent radical cystectomy, pelvic lymph node dissection, and urinary diversion, half were randomized to open surgery and half to robot-assisted laparoscopic surgery. We compared the rate of complications within 90 d after surgery for the open group versus the ...

More than 1,000,000 men undergo prostate biopsy each year in the United States, most for “elevated” serum prostate specific antigen (PSA). Given the lack of specificity and unclear mortality benefit of PSA testing, methods to individualize management of elevated PSA are needed. Greater than 50% of PSA-screened prostate cancers harbor fusions between the transmembrane protease, serine 2 (TMPRSS2) and v-ets erythroblastosis virus E26 oncogene homolog (avian) (ERG) genes. Here, we report a clinical-grade, transcription-mediated amplification assay to risk stratify and detect prostate cancer noninvasively in urine. The TMPRSS2:ERG fusion transcript was quantitatively measured in prospectively collected whole urine from 1312 men at multiple centers. Urine TMPRSS2:ERG was associated with indicators of clinically significant cancer at biopsy and prostatectomy, including tumor size, high Gleason score at prostatectomy, and upgrading of Gleason grade at prostatectomy. TMPRSS2:ERG, in combination with urine prostate cancer antigen 3 (PCA3), improved the performance of the multivariate Prostate Cancer Prevention Trial risk calculator in predicting cancer on biopsy. In the biopsy cohorts, men in the highest and lowest of three TMPRSS2:ERG+PCA3 score groups had markedly different rates of cancer, clinically significant cancer by Epstein criteria, and high-grade cancer on biopsy. Our results demonstrate that urine TMPRSS2:ERG, in combination with urine PCA3, enhances the utility of serum PSA for predicting prostate cancer risk and clinically relevant cancer on biopsy.

Introduction Penile constriction devices often present significant challenges to urologic surgeons. Failure to remove such devices can lead to significant ischemia and loss of tissue. Patients often present after several days of ischemia and swelling have developed. Aim This article reviews previously published data on penile constriction devices and strategies for their removal. Additionally, we present new methodologies for extrication. Methods A comprehensive review of the English language literature was performed using MEDLINE. “Penile incarceration” and “penile strangulation” were used as search terms, and a manual bibliographic review of cross-referenced items was performed. Publications prior to 1970 were excluded from our search. Main Outcome Measures Review of published literature on penile constriction devices and their removal. Results Penile incarceration is frequently described in the literature as an isolated case report or small series describing the approach of a single physician or group of physicians for dealing with these problems. Penile incarceration has been reported in a wide spectrum of age groups, with the incarcerating object most frequently placed for erotic or autoerotic purposes. While the most commonly reported devices causing incarceration are metal rings, higher-grade penile injuries are more frequently sustained by nonmetallic objects. Patients who present with incarceration after 72 hours are more likely to sustain higher-grade injuries than those who seek more timely treatment. Strategies for extrication depend on the type of device used, the length of time of incarceration, the patient's ability to remain calm, and the tools available to the presenting physicians. Conclusion Penile incarceration is a urologic emergency with potentially severe clinical consequences. With rapid intervention and removal of the foreign body, most patients do extremely well and need no further intervention. Removal of such devices can be challenging and often requires resourcefulness and a multidisciplinary approach.

Objectives-We analyzed the prevalence and characteristics of lower urinary tract symptoms (LUTS) in community-dwelling men 80 years and older.Methods-We administered the American Urological Association Symptom Index (AUA-SI) by mail to 291 surviving community-dwelling male participants in the Rancho Bernardo Study, a prospective, community-based study of aging. We compared the prevalence, severity, and types of LUTS occurring in men who were ≥ 80 years to those < 80 years.Results-The mean age was 74.6 years (standard deviation [SD] 8.9, range 48.3-97.1). One third of respondents were ≥ 80. The mean total AUA-SI score increased steadily by decade of life (P-trend = 0.002). The prevalence of LUTS was 70% in men ≥ 80 years and 56% in men < 80 years (P = 0.03). Men ≥ 80 had significantly higher mean total AUA-SI (P = 0.05) and were more likely to complain of incomplete emptying (odds ratio [OR] 2.12, 95% confidence interval [CI] 1.06 to 4.18, P = 0.02), frequency (OR 1.83, 95% CI 1.00 to 3.31, P = 0.03), urgency (OR 1.76, 95% CI 0.96 to 3.20, P = 0.05), and weak stream (OR 1.78, 95% CI 1.01 to 3.12, P = 0.03).Conclusions-In this cohort of community-dwelling men, prevalence and severity of LUTS increased into the 10th decade of life. Compared to younger men, men ≥ 80 were more likely to complain of incomplete emptying, frequency, urgency, and weak stream. Further studies of LUTS in older men are needed to better delineate these associations.

Background The extent of lymphadenectomy needed to optimize oncologic outcomes after radical cystectomy (RC) for patients with regionally advanced bladder cancer (BCa) is unclear. Objective Evaluate the effect of the location of lymph node metastasis on recurrence-free survival (RFS) and cancer-specific survival (CSS) for patients undergoing RC with a mapping pelvic lymph node dissection (PLND). Design, setting, and participants A study of 591 patients undergoing RC with mapping PLND was completed between 2000 and 2010. Median follow-up was 30 mo. Intervention RC with mapping PLND. Measurements We evaluated the impact of lymph node involvement by location on disease outcomes using the 2010 TNM staging system. Survival estimates were described using Kaplan-Meier methods. Gender, age, pathologic stage, histology, number of positive nodes, node density, use of perioperative chemotherapy, and grade were evaluated as predictors of RFS and CSS using multivariate Cox proportional hazard regression. Results and limitations Overall, 114 patients (19%) had lymph node involvement, and 42 patients (7%) had pN3 disease. On multivariate analysis, the number of positive lymph nodes (one or two or more) was significantly associated with increased risk of cancer-specific death (hazard ratio [HR]: 1.9 [95% confidence interval (CI), 1.04–3.46], p = 0.036; versus HR: 4.3 [95% CI, 2.25–8.34], p < 0.0005). Positive lymph node location was not an independent predictor of RFS or CSS. Five-year RFS for pN3 patients undergoing RC with PLND was 25% (95% CI, 22–54). This finding was not statistically different from our pN1 and pN2 patients (38% [95% CI, 22–54] and 35% [95% CI, 11–60], respectively). This study is limited by the lack of prospective randomization and a control group. Conclusions The outcome for patients with involved common iliac lymph nodes was similar to the outcome for patients with primary nodal basin disease. These data support inclusion of the common iliac lymph nodes (pN3) in the nodal staging system for BCa. Lymph node location was not an independent predictor of outcome, whereas the number of positive lymph nodes was an independent predictor of worse oncologic outcome (pN1, pN2). Further refinements of the TNM system to provide improved prognostication are warranted.

To construct patient-specific physical three-dimensional (3D) models of renal units with materials that approximates the properties of renal tissue to allow pre-operative and robotic training surgical simulation, 3D physical kidney models were created (3DSystems, Rock Hill, SC) using computerized tomography to segment structures of interest (parenchyma, vasculature, collection system, and tumor). Images were converted to a 3D surface mesh file for fabrication using a multi-jet 3D printer. A novel construction technique was employed to approximate normal renal tissue texture, printers selectively deposited photopolymer material forming the outer shell of the kidney, and subsequently, an agarose gel solution was injected into the inner cavity recreating the spongier renal parenchyma. We constructed seven models of renal units with suspected malignancies. Partial nephrectomy and renorrhaphy were performed on each of the replicas. Subsequently all patients successfully underwent robotic partial nephrectomy. Average tumor diameter was 4.4 cm, warm ischemia time was 25 min, RENAL nephrometry score was 7.4, and surgical margins were negative. A comparison was made between the seven cases and the Tulane Urology prospectively maintained robotic partial nephrectomy database. Patients with surgical models had larger tumors, higher nephrometry score, longer warm ischemic time, fewer positive surgical margins, shorter hospitalization, and fewer post-operative complications; however, the only significant finding was lower estimated blood loss (186 cc vs 236; p = 0.01). In this feasibility study, pre-operative resectable physical 3D models can be constructed and used as patient-specific surgical simulation tools; further study will need to demonstrate if this results in improvement of surgical outcomes and robotic simulation education.
