BACKGROUND AND PURPOSE Robot-assisted partial nephrectomy (RPN) has emerged as a viable approach to minimally invasive surgery for small renal tumors. There are few reports of RPN for tumors >4 cm. Our objective was to evaluate outcomes of RPN for tumors >4 cm compared with RPN for tumors ≤ 4 cm in a large multi-institutional study. PATIENTS AND METHODS(More)
BACKGROUND AND PURPOSE Robot-assisted partial nephrectomy (RAPN) is an emerging technique for minimally invasive nephron-sparing surgery that may facilitate the technical challenges of sutured renorrhaphy. Barbed suture allows for knotless wound closure and improves suturing efficiency. We present the first clinical study of barbed suture for renorrhaphy(More)
PURPOSE We evaluated the incidence of perioperative complications after robotic partial nephrectomy. MATERIALS AND METHODS We retrospectively reviewed the records of patients treated with robotic assisted partial nephrectomy across the 4 participating institutions. Demographic, blood loss, warm ischemia time, and intraoperative and postoperative(More)
OBJECTIVES Accurate tumor identification during partial nephrectomy is essential for successful tumor control. Intraoperative laparoscopic ultrasonography is useful for tumor localization, but the ultrasound probe is controlled by the assistant rather than the surgeon. We evaluated our initial experience using a robotic ultrasound probe that is controlled(More)
PURPOSE To report our experience with robot-assisted partial nephrectomy (RAPN) in obese patients compared with a contemporary cohort of nonobese patients. PATIENTS AND METHODS We defined obesity as a body mass index (BMI) ≥ 30 kg/m(2). From June 2004 to September 2009, 97 patients underwent RAPN at our institution, of whom 49 were obese (group 1) and 48(More)
OBJECTIVE • To evaluate our experience with robotic partial nephrectomy in patients with previous abdominal surgery and evaluate the effect of previous abdominal surgery on perioperative outcomes. We also describe a technique for intraperitoneal access for patients with prior abdominal surgery utilizing the 8 mm robotic camera for direct-vision trocar(More)
OBJECTIVE To review the outcomes of robot-assisted laparoscopic nephrectomy (RALN) after 101 consecutive cases, the largest reported series to date. The benefit of adding robotic technology to laparoscopic nephrectomy is unclear and controversial. We used robotics for nephrectomy routinely, including for simpler cases rather than laparoscopy, as well as for(More)
BACKGROUND AND OBJECTIVES The need for a skilled assistant to perform hilar clamping during robotic partial nephrectomy is a potential limitation of the technique. We describe our experience using robotic bulldog clamps applied by the console surgeon for hilar clamping. METHODS A total of 60 consecutive patients underwent robotic partial nephrectomy, 30(More)
Computer-assisted robotic renal surgery (CARRS) is a minimally invasive surgical treatment option for renal tumors. We review the literature regarding techniques and outcomes and the potential advantages of CARRS. We retrospectively reviewed the literature regarding techniques and outcomes of CARRS, with specific analysis on robotic radical nephrectomy(More)
The practice of extended pelvic lymph node dissection (ePLND) remains one of the most controversial topics in the management of clinically localized prostate cancer. Although most urologists agree on its benefit for staging and prognostication, the role of the ePLND in cancer control continues to be debated. The increased perioperative morbidity makes it(More)
