OBJECTIVE: To present an evidence-based review of the perioperative management of the radical cystectomy (RC) patient in the context of a care redesign initiative. METHODS: A comprehensive review of the key factors associated with perioperative management of the RC patient was completed. PubMed, Medline, and the Cochrane databases were queried via a computerized search. Specific topics were reviewed within the scope of the three major phases of perioperative management: preoperative, intraoperative, and postoperative...

PURPOSE: Genitourinary infection after ureteroscopy with laser lithotripsy is a clinically significant event that may lead to expensive and morbid return to the hospital. We evaluate factors associated with infection after ureteroscopy with laser lithotripsy leading to unplanned hospital return. MATERIALS AND METHODS: We performed a retrospective chart review evaluating all ureteroscopy with laser lithotripsy performed at a single academic institution from April 2011 to August 2014...

BACKGROUND: The uptake of robotic surgery has led to changes in potential operative complications, as many surgeons learn minimally invasive surgery, and has allowed the documentation of such complications through the routine collection of intraoperative video. OBJECTIVE: We documented intraoperative complications from robot-assisted radical prostatectomy (RARP) with the aim of reporting the mechanisms, etiology, and necessary steps to avoid them. Our goal was to facilitate learning from these complications to improve patient care...

OBJECTIVE: To evaluate kidney functional and overall survival (OS) outcomes in a cohort of patients who underwent partial nephrectomy (PN) or radical nephrectomy (RN) for tumors ≤4 cm. MATERIALS AND METHODS: We performed a retrospective study on 2110 patients who underwent PN or RN with normal contralateral kidneys and normal serum creatinine from 1989 through 2012. Estimated glomerular filtration rate (eGFR) was calculated using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation...

PURPOSE: Robotic assisted radical prostatectomy has largely replaced open radical prostatectomy for the surgical management of prostate cancer despite conflicting evidence of superiority with respect to disease control or functional sequelae. Using population cohort data, in this study we examined sexual and urinary function in men undergoing open radical prostatectomy vs those undergoing robotic assisted radical prostatectomy. MATERIALS AND METHODS: Subjects surgically treated for prostate cancer were selected from 2 large population based prospective cohort studies, the Prostate Cancer Outcomes Study (enrolled 1994 to 1995) and the Comparative Effectiveness Analysis of Surgery and Radiation (enrolled 2011 to 2012)...

PURPOSE: Since its introduction in 1996 Mulcahy salvage has significantly improved outcomes for the removal and replacement of infected inflatable penile prostheses. Long-term followup data of Mulcahy salvage show an infection-free rate of 82%. A multicenter retrospective analysis of the malleable implant salvage technique was conducted to assess infection outcomes and the feasibility of conversion from malleable device back to inflatable penile prosthesis. MATERIALS AND METHODS: This is a retrospective, institutional review board exempt, multi-institution study of 58 patients who underwent Mulcahy salvage with inflatable penile prosthesis removal and replacement with malleable prosthesis...

IMPORTANCE: Targeted magnetic resonance (MR)/ultrasound fusion prostate biopsy has been shown to detect prostate cancer. The implications of targeted biopsy alone vs standard extended-sextant biopsy or the 2 modalities combined are not well understood. OBJECTIVE: To assess targeted vs standard biopsy and the 2 approaches combined for the diagnosis of intermediate- to high-risk prostate cancer. DESIGN, SETTING, AND PARTICIPANTS: Prospective cohort study of 1003 men undergoing both targeted and standard biopsy concurrently from 2007 through 2014 at the National Cancer Institute in the United States...

BACKGROUND: Androgen-deprivation therapy (ADT) has been the backbone of treatment for metastatic prostate cancer since the 1940s. We assessed whether concomitant treatment with ADT plus docetaxel would result in longer overall survival than that with ADT alone. METHODS: We assigned men with metastatic, hormone-sensitive prostate cancer to receive either ADT plus docetaxel (at a dose of 75 mg per square meter of body-surface area every 3 weeks for six cycles) or ADT alone...

OBJECTIVE: To determine the ability of ureterorenoscopy (URS) to identify the precise number and location of all lesions as compared with pathologic review of nephroureterectomy specimens, which have not been previously determined. Upper tract urothelial carcinoma (UTUC) comprises 5% of all urothelial malignancies in the United States. With advances in endoscopic equipment, there has been a move toward using flexible ureteroscopes to perform URS as part of the diagnostic evaluation and management...

PURPOSE: The availability of newly approved treatment options for metastatic castration resistant prostate cancer is not matched with conclusive data on optimal sequencing strategies and resistance patterns. A comprehensive review of efficacy and safety data for new agents and current knowledge regarding treatment sequencing would enable treating physicians to make rational drug selections in patients with metastatic castration resistant prostate cancer. MATERIALS AND METHODS: We searched MEDLINE® and relevant congresses for data on cabazitaxel, docetaxel, 223radium dichloride, abiraterone, enzalutamide and sipuleucel-T, focusing on sequencing strategies, resistance mechanisms and biomarkers of response...

OBJECTIVE: To assess the efficacy of photoselective vaporization of the prostate (PVP) and the predictive factors of treatment failure in patients with refractory urinary retention. MATERIALS AND METHODS: From January 2006 to December 2013, we prospectively included all patients treated by PVP preoperatively catheterized for urinary retention. The primary end point was the number of patients free of indwelling catheters 3 months after the procedure. Univariate and multivariate analyses were performed to identify the predictive factors of treatment failure...

BACKGROUND: Prior to the introduction and dissemination of robot-assisted radical prostatectomy (RARP), population-based studies comparing open radical prostatectomy (ORP) and minimally invasive radical prostatectomy (MIRP) found no clinically significant difference in perioperative complication rates. OBJECTIVE: Assess the rate of RARP utilization and reexamine the difference in perioperative complication rates between RARP and ORP in light of RARP's supplanting laparoscopic radical prostatectomy (LRP) as the most common MIRP technique...

Chronic exposure to excess glucorticoids results in diverse manifestations of Cushing's syndrome, including debilitating morbidities and increased mortality. Genetic and molecular mechanisms responsible for excess cortisol secretion by primary adrenal lesions and adrenocorticotropic hormone (ACTH) secretion from corticotroph or ectopic tumours have been identified. New biochemical and imaging diagnostic approaches and progress in surgical and radiotherapy techniques have improved the management of patients...

PURPOSE: We sought to describe and evaluate the complications related to percutaneous nephrolithotomy and identify risk factors of morbidity according to the modified Clavien scoring system. We also sought to specify which perioperative factors are associated with minor and major complications. MATERIALS AND METHODS: We retrospectively analyzed data on patients who underwent percutaneous nephrolithotomy from 1990 to 2013. Descriptive statistics were used to analyze patient characteristics, medical comorbidities and perioperative features...

BACKGROUND: Despite revisions in 2005 and 2014, the Gleason prostate cancer (PCa) grading system still has major deficiencies. Combining of Gleason scores into a three-tiered grouping (6, 7, 8-10) is used most frequently for prognostic and therapeutic purposes. The lowest score, assigned 6, may be misunderstood as a cancer in the middle of the grading scale, and 3+4=7 and 4+3=7 are often considered the same prognostic group. OBJECTIVE: To verify that a new grading system accurately produces a smaller number of grades with the most significant prognostic differences, using multi-institutional and multimodal therapy data...

PURPOSE: We dissected prevailing assumptions about cryptorchidism and reviewed data that support and reject these assumptions. MATERIALS AND METHODS: Five questions about cryptorchidism and the risk of testicular cancer were identified because of their implications in parent counseling and clinical management. Standard search techniques through MEDLINE were used to identify all relevant English language studies of the questions being examined. Each of the 5 questions was then examined in light of the existing data...

OBJECTIVE: To evaluate long-term device outcomes following primary artificial urinary sphincter (AUS) implantation. MATERIALS AND METHODS: We identified 1802 male patients with stress urinary incontinence that underwent AUS placement from 1983 to 2011. Of these, 1082 (60%) were involving primary implantations and comprise the study cohort. Multiple clinical and surgical variables were evaluated for potential association with treatment failure, defined as any secondary surgery...

OBJECTIVE: To evaluate the peri-operative, functional and oncological outcomes of robot-assisted partial nephrectomy (RAPN) and laparoscopic partial nephrectomy (LPN) for moderately or highly complex tumours (defined as RENAL nephrometry score ≥7). PATIENTS AND METHODS: We retrospectively analysed the medical charts of 216 patients with complex tumours who underwent LPN (n = 135) or RAPN (n = 81) between 2008 and 2014. Peri-operative data, pathological variables, complications, functional and oncological outcomes were reviewed...

PURPOSE: To examine the effect of days off between cases on perioperative outcomes for robotic-assisted laparoscopic prostatectomy (RALP). METHODS: We analyzed a single-surgeon series of 2036 RALP cases between 2003 and 2014. Days between cases (DBC) was calculated as the number of days elapsed since the surgeon's previous RALP with the second start cases assigned 0 DBC. Surgeon experience was assessed by dividing sequential case experience into cases 0-99, cases 100-249, cases 250-999, and cases 1000+ based on previously reported learning curve data for RALP...
