PURPOSE Laparoscopic partial/wedge nephrectomy, similar to laparoscopic radical prostatectomy, is a technically challenging procedure that is performed by a limited number of expert laparoscopic surgeons. The incorporation of a robotic surgical interface has dramatically increased the use of minimally invasive pelvic surgery such that robotic laparoscopic(More)
PURPOSE To compare our experience with laparoscopic radical cystectomy (LACIC) and robot-assisted laparoscopic radical cystectomy (RACIC) with ileal conduit urinary diversion. PATIENTS AND METHODS Prospective data were gathered on 20 consecutive patients undergoing LACIC performed between August 2002 and July 2005, and on 14 consecutive patients(More)
PURPOSE Retropulsion of ureteral stones during laser lithotripsy may result in difficult and incomplete stone fragmentation. The Stone Cone nitinol urological retrieval coil and the NTrap nitinol ureteral occlusion device have been introduced into clinical practice to possibly limit stone retropulsion and enhance the efficiency of holmium laser (Convergent(More)
INTRODUCTION Pelvic lymph node dissection (PLND) at the time of radical cystectomy for urothelial carcinoma of the bladder is critical for accurate staging and may improve oncologic outcomes. Minimally invasive approaches have been criticized for limiting the extent of the PLND. We reviewed our experience with PLND and its perioperative outcomes with(More)
BACKGROUND AND PURPOSE Natural orifice translumenal endoscopic surgery (NOTES) using purpose-built equipment has never been applied to urologic surgery. Herein, we present our initial experience with a trans-vaginal single-port NOTES nephrectomy. METHODS AND RESULTS An acute experiment was performed in a female farm pig. A single 12-mm trocar was placed(More)
PURPOSE Sealing the lymphatic vessels during abdominal and pelvic surgery is important to prevent the leakage of lymphatic fluid and its resultant sequelae. To our knowledge we compared for the first time the quality of lymphatic sealing by each of 4 commonly used laparoscopic dissection devices. MATERIALS AND METHODS A total of 12 domestic pigs were used(More)
BACKGROUND AND PURPOSE Natural Orifice Transluminal Endoscopic Surgery (NOTES) using the daVinci robot (Intuitive Surgical, Sunnyvale, CA) has never been applied to urologic surgery. Here we present our initial experience with a combined transvaginal and transcolonic, single-port, robot-assisted NOTES nephrectomy. METHODS An acute experiment was performed(More)
BACKGROUND AND PURPOSE The effects of commonly used reprocessing methods on flexible ureteroscope longevity have never been examined. We prospectively studied the effects of Steris 1 sterilization and Cidex ortho-phthalaldehyde (OPA) high-level disinfection (HLD) on the image quality, physical structure, and deflective properties of two new flexible(More)
OBJECTIVE • To describe six steps for haemostasis and collecting system closure ('six degrees of haemostasis') that are reproducible and that minimize the two most concerning complications of laparoscopic partial nephrectomy: haemorrhage and urine leakage. METHODS • A retrospective study of 23 consecutive laparoscopic partial nephrectomy cases performed(More)
OBJECTIVE We developed a simple, inexpensive model to simulate four reconstructive laparoscopic procedures: pyeloplasty, vesicourethral anastomosis, bladder injury repair, and partial nephrectomy. MATERIALS AND METHODS Liquid silicone was applied in layers to a mold to create the 4-in-1 model. A questionnaire evaluating its face and content validity was(More)
