BACKGROUND AND PURPOSE Previous reports have suggested that a 2% to 5% device failure rate (FR) be quoted when counseling patients about robot-assisted laparoscopic radical prostatectomy (RLRP). We sought to evaluate our FR on the da Vinci system. PATIENTS AND METHODS Since February 2003, more than 800 RLRPs have been performed at our institution using a(More)
OBJECTIVES To determine the effect of prostate weight (PW) on robotic laparoscopic radical prostatectomy (RLRP) outcomes. The effect of PW on surgical and pathologic outcomes has been reviewed in open and laparoscopic prostatectomy series. Little is known about its effects during RLRP. METHODS From February 2003 to November 2005, 375 men underwent RLRP.(More)
The effects of hippocampal ablation on acquisition rates and temporal characteristics of classically conditioned nictitating membrane responses were examined in groups of rabbits trained with a 150-, 300-, or 600-ms interstimulus interval. Acquisition rates were accelerated in the 150- and 600-ms groups. No effect was present in the 300-ms group. Response(More)
INTRODUCTION Robotic-assisted laparoscopic radical prostatectomy (RLRP) is increasingly becoming an alternative to open and laparoscopic radical prostatectomy in the treatment of localized prostate cancer. RLRP has been associated with low morbidity, short convalescence and comparable oncologic and functional outcomes. We report our initial experience of(More)
The effects of dorsal hippocampal lesions on retention of classical trace conditioned responses were examined using the rabbit nictitating membrane preparation. Animals were trained to criteria and then lesioned either in the cortex or in the hippocampus and the cortex. Hippocampal damage had no effect on the retention of responses but produced(More)
OBJECTIVES To report our experience with the use of fibrin glue during tubeless percutaneous nephrolithotomy. We addressed the safety of this approach and evaluated its use for any clinical benefit with respect to length of hospital stay, bleeding, analgesic usage, and urinary extravasation. METHODS This was a retrospective review of 43 patients who(More)
The purpose of this study was to determine whether a relationship existed between MIB-1 labeling index (LI) percentages and survival in patients with grade II astrocytomas. From archival paraffin-embedded surgical specimens of 50 patients of the University of Michigan Medical Center with World Health Organization grade II astrocytomas, 22 patients had a(More)
OBJECTIVES To present our technique, modifications, and experience of laparoscopic partial nephrectomy (LPN). Nephron-sparing surgery is an increasingly accepted treatment for selected T1a kidney tumors. Because of the more complex surgical technique involved, LPN is evolving more slowly than laparoscopic radical nephrectomy. METHODS The data of 41(More)
OBJECTIVES Medical therapy often fails to cure benign retroperitoneal fibrosis (RPF), necessitating a surgical approach. Preoperative and postoperative adjuvant medical therapy and the timing of surgical intervention are not well-established. We surveyed centers of laparoscopic excellence to determine the current practices in the treatment of RPF. METHODS(More)
OBJECTIVES The intraoperative complexity of laparoscopic partial nephrectomy (LPN) for upper pole renal tumors is recognized. We report on the technical feasibility and operative outcomes of LPN for upper pole tumors (UPLPN) and lower pole tumors (LPLPN), and open partial nephrectomy (UPOPN) for upper pole tumors. METHODS We retrospectively reviewed our(More)
