PURPOSE Minimally invasive surgery has been shown to decrease postoperative morbidity and length of stay for a number of surgical procedures. Furthermore, length of stay after open radical prostatectomy has decreased dramatically during the last decade. We examined differences in length of stay between a prospectively evaluated cohort of patients who(More)
PURPOSE Treatment of organ confined renal masses with partial nephrectomy has durable oncologic outcomes comparable to radical nephrectomy. Partial nephrectomy is associated with lower risk of chronic kidney disease and in some series with better overall survival. We report a contemporary analysis on national trends of partial nephrectomy use to determine(More)
BACKGROUND The role of malnutrition has not been well studied in patients undergoing surgery for renal cell carcinoma (RCC). OBJECTIVE Our aim was to evaluate whether nutritional deficiency (ND) is an important determinant of survival following surgery for RCC. DESIGN, SETTING, AND PARTICIPANTS A total of 369 consecutive patients underwent surgery for(More)
PURPOSE Surgical technique, patient characteristics and method of pathological review may influence surgical margin status. We evaluated the incidence and location of positive surgical margins in 200 sequential robotic assisted laparoscopic radical prostatectomy and 200 sequential open radical retropubic prostatectomy cases. MATERIALS AND METHODS From(More)
Although equipment for performance of robotic-assisted laparoscopic prostatectomy (RALP) is becoming more widely available, few surgeons have acquired the skill and experience necessary to master RALP. A significant issue has been the requisite training and experience (ie, the "learning curve") necessary for a qualified surgeon to become an expert at RALP.(More)
PURPOSE The purpose of this guideline is to provide a clinical framework for follow-up of clinically localized renal neoplasms undergoing active surveillance, or following definitive therapy. MATERIALS AND METHODS A systematic literature review identified published articles in the English literature between January 1999 and 2011 relevant to key questions(More)
OBJECTIVE To determine whether robotic-assisted laparoscopic radical prostatectomy (RALP) is associated with a lower transfusion rate than radical retropubic prostatectomy (RRP). PATIENTS AND METHODS In this cohort study, we evaluated 1244 consecutive patients who underwent RALP (830) or RRP (414) between June 2003 and July 2006. Demographics, clinical(More)
OBJECTIVE To compare biochemical recurrence (BCR)-free survival and predictors of BCR in intermediate-risk (IR) and high-risk (HR) patients undergoing robotic-assisted laparoscopic prostatectomy (RALP) vs open radical prostatectomy (ORP). MATERIALS AND METHODS We conducted a retrospective study on 1336 men with D'Amico IR or HR prostate cancer who(More)
OBJECTIVE To evaluate the outcomes based on gland size between robotically assisted radical prostatectomy (RALP) and open RP (RRP), as larger prostates might increase the difficulty of RP. PATIENTS AND METHODS We reviewed 660 patients who had RALP and 340 who had RRP from May 2003 to August 2006; the patients were divided into two groups, with a prostate(More)
Natural orifice endoscopic surgery can enable incisionless approaches, but a major challenge is the lack of small and dexterous instrumentation. Surgical robots have the potential to meet this need yet often disrupt the clinical workflow. Hand-held robots that combine thin manipulators and endoscopes have the potential to address this by integrating(More)
