OBJECTIVE To analyze outcomes and complications of percutaneous (PRC) and laparoscopic renal cryoablation (LRC) using the radius, endophytic, nearness to collecting system, anterior/posterior, and location (RENAL) nephrometry system. METHODS Retrospective multicenter analysis of 154 consecutive patients who underwent either ultrasound-guided LRC (n = 88)(More)
OBJECTIVE To determine if partial nephrectomy (PN) confers a renal functional benefit compared to radical nephrectomy (RN) for clinical T2 renal masses (T2RM) when adjusting for tumor complexity characterized by the RENAL nephrometry score. METHODS A 2-center study of 202 patients with T2RM undergoing RN (122) or PN (80) (median follow-up, 41.5 months).(More)
OBJECTIVE We evaluated survival outcomes of partial nephrectomy (PN) and radical nephrectomy (RN) for clinical T2 renal masses (cT2RM) controlling for R.E.N.A.L. nephrometry score. PATIENTS AND METHODS A two-centre study comprised of 202 patients with cT2RM who underwent RN (122) or PN (80) between July 2002 and June 2012 (median follow-up 41.5 months).(More)
PURPOSE To report the use and complication rates of percutaneous nephrolithotomy (PCNL) performed in the United States between 1998 and 2009. PATIENTS AND METHODS The Nationwide Inpatient Sample database was analyzed from 1998 to 2009 to identify all PCNL cases performed in adults ≥18 years old. Descriptive statistics were used for potential covariates:(More)
BACKGROUND AND PURPOSE Roux-en-Y gastric bypass (RYGB) surgery, a mixed malabsorptive/restrictive procedure, is associated with enteric hyperoxaluria and an increased risk of kidney stones. The incidence of nephrolithiasis after purely restrictive bariatric procedures such as adjustable gastric banding or sleeve gastrectomy has not been well described. We(More)
BACKGROUND Robotic technology disseminated into urological practice without robust comparative effectiveness data. OBJECTIVE To review the diffusion of robotic surgery into urological practice. METHODS We performed a comprehensive literature review focusing on diffusion patterns, patient safety, learning curves, and comparative costs for robotic radical(More)
OBJECTIVE Currently, robotic training for inexperienced, practicing surgeons is primarily done vis-à-vis industry and/or society-sponsored day or weekend courses, with limited proctorship opportunities. The objective of this study was to assess the impact of an extended-proctorship program at up to 32 months of follow-up. METHODS An extended-proctorship(More)
PURPOSE To compare renal function outcomes in patients undergoing radical nephroureterectomy (RNU) or partial (distal) ureterectomy (PU) for upper tract urothelial carcinoma (UTUC). METHODS Clinicopathologic data of patients undergoing RNU or PU for UTUC from 1998 to 2012 were compiled. Glomerular filtration rate was calculated preoperatively and(More)
PURPOSE To describe the utilization of shockwave lithotripsy (SWL) and ureteroscopy (URS) in ambulatory surgery centers, as well as to identify patient-specific factors predictive of one procedure over the other. PATIENTS AND METHODS We evaluated the current trends in the use of SWL and URS in the ambulatory settings over a 5-year period in the state of(More)
BACKGROUND AND PURPOSE Protease inhibitors, specifically indinavir, have historically been implicated as a cause of nephrolithiasis in the human immunodeficiency virus (HIV) infected patients. There is a paucity of data, however, on stone disease with nonindinavir etiologies since the introduction of highly active antiretroviral therapy (HAART). We sought(More)
