PURPOSE Statins are cholesterol lowering agents used to prevent cardiovascular disease. Evidence suggests a dichotomous effect of statins with cancer inhibiting and promoting properties. To our knowledge the effect of statins on the prognosis of muscle invasive urothelial carcinoma of the bladder remains uninvestigated to date. We tested the hypothesis that statin use impacts oncological outcomes in patients treated with radical cystectomy for urothelial carcinoma of the bladder. MATERIALS AND METHODS We retrospectively evaluated the records of 1,502 patients treated with radical cystectomy and pelvic lymphadenectomy without neoadjuvant therapy at a total of 4 institutions. Cox regression models were used to determine the association of statins with disease recurrence and cancer specific mortality. RESULTS A total of 642 patients (42.7%) were on statins. At a median followup of 34 months 509 patients (33.9%) experienced disease recurrence and 402 (26.8%) had died of urothelial carcinoma of the bladder. Statin users were older (p = 0.003), had a higher body mass index (median 32 vs 28 kg/m(2), p <0.001) and were more likely to have positive soft tissue surgical margins (9% vs 4%, p <0.001). On univariable Cox regression analysis statins, female gender, advanced age, higher body mass index, smoking status, tumor stage, tumor grade, soft tissue surgical margin status, lymphovascular invasion, lymph node metastasis and adjuvant chemotherapy were associated with disease recurrence (p ≤ 0.05) and cancer specific mortality (p ≤ 0.02). On multivariable Cox regression analysis statin use was not associated with either outcome. CONCLUSIONS Statin users were at higher risk for disease recurrence and cancer specific mortality on univariable but not multivariable analysis. These data do not support modification of statin use in patients with high risk urothelial carcinoma of the bladder who will be treated with radical cystectomy.

BACKGROUND Surgical treatment of lower extremity fractures commonly involves the use of orthopedic table with perineal post for countertraction. However, prolonged application of the perineal post has been associated with significant complications. We describe our experience in the management of genitoperineal cutaneous injuries associated with the use of a traction table. METHODS Six patients with genitoperineal complications attributed to the use of a traction table were treated at our institution over a period of 2 years. The patients median age was 25 (range, 20-28) years and all had fractures caused by motor vehicle collision. We evaluated the clinical presentation of these perineal injuries, operative time, therapeutic approach, clinical outcomes, and hospitalization time. RESULTS The mean operative time of the orthopedic surgery was 318 minutes +/- 128 minutes (range, 185-540). All patients developed a partial-thickness necrotic area involving the perineum and scrotum in 2 days to 15 days (mean, 7 +/- 5.4) after the surgery. Three patients developed infection of the necrotic tissue. All patients underwent surgical debridement 16.5 days +/- 6.5 days (range, 13-29) after the orthopedic surgery and only one debridement procedure was necessary in all cases. A primary wound closure was possible in one case, and in the other cases the wound healed completely by second intention. The mean hospitalization time was 26.3 days +/- 9.7 days (range, 19-44). CONCLUSION Genitoperineal skin necrosis induced by perineal traction posttable is a morbid complication that demands surgical debridement and prolonged hospitalization for your treatment. There are many procedures available to reduce the risk of this complication that should be used more liberally by the orthopedic surgeons.

Purpose Early surgical management is the standard of care for penile fracture. Conservative treatment is an option with recent reports revealing lower success rates. We reviewed the data and long-term outcomes of patients with penile injury submitted to surgical or conservative treatment. Materials and Methods Between January 2004 and February 2012, 42 patients with penile blunt trauma on an erect penis were admitted to our center. We analyzed the following variables: age, etiology, symptoms and signs, diagnostic tests, treatment used, complications and erectile function during the follow-up. One patient was excluded due to missing information. Thirty-five patients underwent surgical repair and 6 patients were submitted to conservative management. Results Mean follow-up was 19.2 months (range, 7 days to 72 months). The mean elapsed time from trauma to surgery was 21.3±12.5 hours. Trauma during sexual relationship was the main cause (80.9%) of penile fracture. Urethral injury was present in five patients submitted to surgery. Dorsal vein injury occurred in three patients with false penile fracture and concomitant spongious corpus lesion was present in three patients. During follow-up, 31 cases (88.6%) of the surgical group and four cases (66.7%) of the conservative group reported sufficient erections for intercourse, with no voiding dysfunction and no penile curvature. However, the remaining two patients (33.3%) from the conservative group developed erectile dysfunction and three patients (50%) developed penile deviation. Conclusions Surgical approach provides excellent functional outcomes and lower complications. Early surgical management of penile fracture provides superior results and conservative approach should be avoided.

ABSTRACT Introduction and objective: Radical prostatectomy is a first-line treatment for localized prostate cancer. However, in some cases, biochemical recurrence associated with imaging-detected nodal metastases may happen. Herein, we aim to present the surgical technique for salvage lymph node dissection after radical prostatectomy. Materials and Methods: A 70 year-old asymptomatic man presented with a prostate-specific antigen (PSA) of 7.45ng/ mL. Digital rectal examination was normal and trans-rectal prostate biopsy revealed a prostate adenocarcinoma Gleason 7 (3+4). Pre-operative computed tomography scan and bone scintigraphy showed no metastatic disease. In other service, the patient underwent a robotic-assisted radical prostatectomy plus obturador lymphadenectomy. Pathologic examination showed a pT3aN0 tumor. After 6 months of follow-up, serum PSA was 1.45ng/mL. Further investigation with 11C–Choline PET/CT revealed only a 2-cm lymph node close to the left internal iliac artery. The patient was counseled for salvage lymph node dissection. Results: Salvage lymph node dissection was uneventfully performed. Operative time was 1.5 hour, blood loss was minimal, and there were no intra- or postoperative complications. The patient was discharged from hospital in the 1st postoperative day. After 12 months of follow-up, his PSA was undetectable with no other adjuvant therapy. Conclusion: Robotic salvage pelvic lymph node dissection is an effective option for treatment of patients with biochemical recurrence after radical prostatectomy and only pelvic lymph node metastasis detected by C11-Choline PET/CT.

PURPOSE To assess the impact of eliminating routine drain placement in patients undergoing robot-assisted laparoscopic prostatectomy (RALP) and pelvic lymph node dissection (PLND) on the risk of postoperative complications. PATIENTS AND METHODS An experienced single surgeon performed RALP on 651 consecutive patients at our institution from 2008 to 2012. Before August 2011, RALP with or without PLND included a routine peritoneal drain placed during surgery. Thereafter, routine intraoperative placement of drains was omitted, except for intraoperatively noted anastomotic leakage. We used multivariable logistic regression to compare complication rates between study periods and the actual drain placement status after adjusting for standard prespecified covariates. RESULTS Most patients (92%) did not have ≥grade 2 complications after surgery and only two patients (0.3%) experienced a grade 4 complication. The absolute adjusted risk of a grade 2-5 complication was 0.9% greater among those treated before August 2011 (95% confidence interval [CI] -3.3%-5.1%; p=0.7), while absolute adjusted risk of a grade 3-5 complication was 2.8% less (-2.8%; 95% CI-5.3%-0.1%; p=0.061). RESULTS based on drain status were similar. CONCLUSIONS Routine peritoneal drain placement following RALP with PLND did not confer a significant advantage in terms of postoperative complications. Further data are necessary to confirm that it is safe to omit drains in most patients.

Introduction Penile refracture is an exceedingly rare event, with very few published studies. To the best of our knowledge, this is the first documented case in the literature of penile fracture with 3 same-site recurrences. Aims To describe the case of a 25-year-old Caucasian man with recurrent penile fracture ultimately treated with resuture and patch reinforcement. Methods Patient history (clinical and surgical) and literature review. Results After the 3rd same-site recurrence, patch reinforcement over the sutured area was performed. The patient had an uneventful recovery and no recurrences to date. Conclusion There is no evidence indicating the superiority of non-absorbable sutures. Bovine pericardium reinforcement over the sutured area was used to minimize the chance of another recurrence. More studies are necessary to investigate its safety and efficacy in this scenario.

OBJECTIVE To evaluate the relation between serum total testosterone (TT) and prostate cancer (PCa) grade and the effect of race and demographic characteristics on such association. METHOD We analyzed 695 patients undergoing radical prostatectomy (RP), of whom 423 had serum TT collected. Patients were classified as having hypogonadism or eugonadism based on two thresholds of testosterone: threshold 1 (300 ng/dL) and threshold 2 (250 ng/dL). We evaluated the relation between TT levels and a Gleason score (GS) ≥ 7 in RP specimens. Outcomes were evaluated using univariate and multivariate analyses, accounting for race and other demographic predictors. RESULTS Out of 423 patients, 37.8% had hypogonadism based on the threshold 1 and 23.9% based on the threshold 2. Patients with hypogonadism, in both thresholds, had a higher chance of GS ≥ 7 (OR 1.79, p=0.02 and OR 2.08, p=0.012, respectively). In the multivariate analysis, adjusted for age, TT, body mass index (BMI) and race, low TT (p=0.023) and age (p=0.002) were found to be independent risk factors for GS ≥ 7. Among Black individuals, low serum TT was a stronger predictor of high-grade disease compared to White men (p=0.02). CONCLUSION Hypogonadism is independently associated to higher GS in localized PCa. The effect of this association is significantly more pronounced among Black men and could partly explain aggressive characteristics of PCa found in this race.
