PURPOSE Laparoscopic partial nephrectomy is an increasingly performed, minimally invasive alternative to open partial nephrectomy. We compared early postoperative outcomes in 1,800 patients undergoing open partial nephrectomy by experienced surgeons with the initial experience with laparoscopic partial nephrectomy in patients with a single renal tumor 7 cm(More)
PURPOSE The oncological efficacy of partial nephrectomy is related to obtaining a negative surgical margin intraoperatively. This study assesses the oncological outcomes of patients undergoing laparoscopic partial nephrectomy for a renal tumor who had positive surgical margin on final pathology. MATERIALS AND METHODS The experiences of 2 surgeons with 511(More)
PURPOSE Partial nephrectomy for hilar tumors represents a technical challenge not only for laparoscopic, but also for open surgeons. We report the technical feasibility and perioperative outcomes of laparoscopic partial nephrectomy (LPN) for hilar tumors. MATERIALS AND METHODS Between January 2001 and September 2004, 25 of 362 patients (6.9%) undergoing(More)
OBJECTIVES Laparoscopic partial nephrectomy (LPN) is a technically challenging procedure for the management of renal tumours. Major complications of LPN include bleeding and urine leakage. Haemostatic agents (HAs) and/or glues may reduce haemorrhage and urine leakage. We sought to examine the current practice patterns for urologists performing LPN with(More)
OBJECTIVES Techniques for laparoscopic radical cystectomy are rapidly evolving. The entire procedure can be performed completely intracorporeally by pure laparoscopic techniques or by open-assisted laparoscopic techniques in which the urinary diversion is constructed extracorporeally by way of a minilaparotomy incision. We retrospectively evaluated the(More)
PURPOSE To report the 5-year oncological outcomes of patients undergoing laparoscopic radical nephrectomy for renal cancer compared to a cohort of patients undergoing open radical nephrectomy. METHODS We retrospectively analyzed the data of 88 patients undergoing radical nephrectomy for renal cell carcinoma prior to January 2000. Of these, 45 patients(More)
PURPOSE We report our experience with LPN for tumor in a solitary kidney. MATERIALS AND METHODS Of 430 patients undergoing LPN since February 1999 at our institution 22 (5%) underwent LPN for tumor in a solitary kidney, as performed by a single surgeon. The laparoscopic technique that we used duplicated open principles, including hilar clamping, cold cut(More)
OBJECTIVES To compare the long-term oncologic and renal function outcomes in patients undergoing laparoscopic (LRN) versus open radical nephrectomy (ORN). METHODS The medical records of 116 patients undergoing radical nephrectomy for pathologically confirmed renal cell carcinoma before January 2000 were reviewed. Of these 116 patients, 63 underwent LRN(More)
PURPOSE LPN is frequently reserved for small, peripherally located tumors. Centrally located tumors typically require complex intracorporeal suturing and reconstruction with hilar clamping, which is a laparoscopically advanced maneuver given the constraints of renal ischemia. We retrospectively compared our experience with central vs peripheral tumors(More)
OBJECTIVES To report our experience with laparoscopic partial nephrectomy in obese (body mass index greater than 30 kg/m2) patients compared with a contemporary cohort of nonobese patients. METHODS From August 1999 to December 2004, 140 obese (group 1) and 238 nonobese (group 2) patients underwent laparoscopic partial nephrectomy at our institution. We(More)
