Abstract Introduction: Radical cystectomy is associated with significant morbidity and cost, with rates of gastrointestinal complications as high as 30%. Alvimopan is a mu opioid receptor antagonist that has been shown in randomized-control trials to accelerate gastrointestinal recovery in patients undergoing bowel resection with primary anastamosis. We report our experience with gastrointestinal recovery for patients undergoing cystectomy with urinary diversion treated with alvimopan and cost benefit associated.
Materials and methods: Between January 2008 and October 2012, 80 patients underwent radical cystectomy with urinary diversion at two institutions. Forty-two patients in our study did not receive alvimopan preoperatively.… More >

Abstract Introduction: Few data on the perioperative outcomes of cystectomy after neoadjuvant chemotherapy (NAC) exist. In this study, we evaluated whether patients who had previously received NAC were at higher risk of developing perioperative complications.
Materials and methods: The National Surgical Quality Improvement Program (NSQIP) database was searched to identify cystectomies performed between January 1, 2005 and December 31, 2011. Of 1394 patients identified, about one-tenth (n = 122 [8.8%]) received NAC. A propensity-weighted comparative analysis of perioperative morbidity was conducted.
Results: In unadjusted comparisons, patients undergoing cystectomy after NAC were more likely to have peripheral nerve deficits (1.6%… More >

Abstract Introduction: Robotic assisted laparoscopic prostatectomy (RALP) is a mainstay in the treatment of prostate cancer. Current procedure terminology (CPT) identifies a case that requires substantially greater effort than usual by using the modifier 22 code (M22). Our objective was to identify the most common etiologies leading to M22 at our institution and determine the effect on perioperative outcomes.
Materials and methods: We retrospectively reviewed our prostatectomy database from 2009–2012 to identify patients who underwent RALP with and without M22. Reasons for M22 were determined by review of operative reports. Comparisons were made using Chi-square analysis and independent… More >

Abstract Introduction: The role of laparoscopic radical nephrectomy (LRN) in the management of very large renal masses has yet to be determined. Moreover, no studies have considered the total size of the specimen removed. We report our experience managing renal masses ≥ 10 cm with transperitoneal LRN.
Materials and methods: We retrospectively reviewed cases of LRN performed in the context of renal masses from 2006 to 2012 at our institution. LRNs were divided into two groups; tumors 10 cm or larger (n = 24) and tumors smaller than 10 cm (n = 124). Patient demographics, tumor characteristics, operative… More >

Abstract Introduction: To report the characteristics and anti-incontinence outcomes of men who fail to demonstrate incontinence on intubated urodynamics (UDS).
Materials and methods: From 2005 to 2013, the records of men who underwent UDS prior to artificial urinary sphincter (AUS) were reviewed. The histories, UDS, endoscopies, and anti-incontinence outcomes of men who failed to demonstrate incontinence on intubated UDS were recorded. In our UDS protocol, the urodynamic urethral catheter was removed and the UDS was repeated to elicit incontinence without the urethral catheter. The valsalva leak point pressure (VLPP) was obtained via the rectal catheter in these men.
Results:… More >

Abstract Introduction: To identify risk factors for PSA bounce (PSAb) and compare characteristics of prostate cancer patients treated with brachytherapy and external beam radiotherapy (EBRT).
Materials and methods: We identified 362 patients treated for low risk prostate adenocarcinoma (D’Amico criteria) with a follow up time of at least 36 months. Patients received either: 1) EBRT 76 Gy in 38 fractions (n = 58); 2) hypofractionated EBRT, 45 Gy in 9 once-weekly fractions (n = 74); 3) seed brachytherapy (n = 230). PSAb was defined as a rise ≥ 0.2 ng/mL with subsequent return to baseline within the first… More >

Abstract Introduction: To investigate the trends in the performance of radical cystectomy (RC) versus partial cystectomy (PC) in the United States over the past 10 years and compare postoperative outcomes between two procedures.
Materials and methods: The data was captured from the Nationwide Inpatient Sample (NIS) 2001-2010 using the appropriate ICD-9-CM diagnosis and procedure codes. Patient sociodemographics, comorbidities and in-hospital complications after PC and RC were compared, taking into account some hospital characteristics. A chi-square analysis including a Cochran-Armitage trend test and a multivariable logistic regression analysis were employed.
Results: RC rate increased from 84.8% in 2001… More >

Abstract Introduction: Partial nephrectomy without renal vascular occlusion has been introduced to improve outcomes in patients undergoing robotic partial nephrectomy (RPN). We prospectively evaluated unclamped RPN at our institution and compared this to other clamping techniques in a non-randomized fashion.
Materials and methods: Ninety-five consecutive patients who successfully completed RPN between June 2010 and October 2011 are included in this analysis. All RPNs were performed by a single surgeon. Clamping technique was artery and vein (AV), artery alone (AO), or unclamped (U), without hypotensive anesthesia. Clamping decision was based on surgeon preference and feasibility of minimizing ischemia. All… More >
