Comparison of laparoscopic and open nephroureterectomy for benign disease.

PURPOSE

We report our experience with laparoscopic nephroureterectomy for benign disease and compare the results to a contemporary group of patients undergoing open nephroureterectomy.

MATERIALS AND METHODS

Between October 1994 and March 1997, 12 women and 4 men with a mean age of 50 years (range 22 to 70) underwent laparoscopic nephroureterectomy at our hospital. Indications for operation were nonfunctioning kidneys due to vesicoureteral reflux with recurrent episodes of pyelonephritis or analgesic nephropathy before a planned renal transplantation. In comparison 11 women and 4 men with a mean age of 40 years (range 18 to 64) underwent open nephroureterectomy for various benign diseases.

RESULTS

Laparoscopic and open nephroureterectomy had no significant differences regarding operative times (100 versus 124 minutes) and complication rates (25 versus 20%). In the laparoscopy group conversion to open surgery was not necessary. Patients who underwent laparoscopic nephroureterectomy had significantly less consumption of morphine equivalent for postoperative pain control (12 versus 40 mg.), shorter time to achieve mobilization and oral intake (11 versus 39 hours), shorter hospital stay (6 versus 12.7 days) and faster return to normal activities (21 versus 39 days).

CONCLUSIONS

Laparoscopic nephroureterectomy in patients with benign disease has similar operative results but obvious postoperative advantages compared to the open approach.
