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)
To compare the efficacy of digital rectal examination and serum prostate specific antigen (PSA) in the early detection of prostate cancer, we conducted a prospective clinical trial at 6 university centers of 6,630 male volunteers 50 years old or older who underwent PSA determination (Hybritech Tandom-E or Tandem-R assays) and digital rectal examination.(More)
OBJECTIVE To assess the long-term oncologic efficacy of laparoscopic radical nephroureterectomy (RNU). METHODS Between August 1993 and May 2001, 39 patients underwent laparoscopic RNU for upper tract transitional cell carcinoma (TCC) at our institution. The medical records of these patients were retrospectively reviewed. RESULTS Clinical outcomes were(More)
Live donor renal transplantation provides significant advantages when compared with cadaveric donor renal transplantation in terms of improved patient and graft survival, a lower incidence of delayed function, and a shorter waiting time. Yet despite these advantages, live donors continue to be an under utilized source of kidneys for transplantation.(More)
PURPOSE Bowel injury is a potential complication of any abdominal or retroperitoneal surgical procedure. We determine the incidence and assess the sequelae of laparoscopic bowel injury, and identify signs and symptoms of an unrecognized injury. MATERIALS AND METHODS Between July 1991 and June 1998 laparoscopic urological procedures were performed in 915(More)
This article evaluates the safety and efficacy of percutaneous radiofrequency ablation (RFA) delivered by computed tomography (CT) fluoroscopic guidance for the treatment of small, solitary renal lesions in high risk surgical and anesthetic patients. In total, 29 patients with 35 small (</=4 cm) renal lesions underwent a total of 37 CT fluoroscopically(More)
A laparoscopic live-donor nephrectomy was performed on a 40-year-old man. The kidney was removed intact via a 9-cm infraumbilical midline incision. Warm ischemia was limited to less than 5 min. Immediately upon revascularization, the allograft produced urine. By the second postoperative day, the recipient's serum creatinine had decreased to 0.7 mg/dl. The(More)
PURPOSE We describe our experience with and results of percutaneous computerized tomography guided radio frequency ablation (RFA) for small (less than 4 cm) renal tumors at a 2-year mean followup. MATERIALS AND METHODS A total of 49 patients (60 renal tumors) with a mean age of 63.9 years underwent percutaneous RFA. Indications for RFA were severe(More)
This paper reports the development of a robotic system designed to extend a human’s ability to perform small-scale (sub-millimeter) manipulation tasks requiring human judgment, sensory integration, and hand-eye coordination. Our novel approach, which we call steady-hand micromanipulation, is for tools to be held simultaneously both by the operator’s hand(More)
