Comparison between standard flank versus laparoscopic nephrectomy for benign renal disease

Abstract

To evaluate the role of laparoscopic nephrectomy in the management of benign renal diseases, 12 patients undergoing laparoscopic nephrectomy were compared to 13 undergoing a classical flank nephrectomy. Both groups were similar in regard to patient age and indications for surgery. The underlying pathological conditions included vesicoureteral reflux, tuberculosis, hydronephrosis, hypertension and failed pyeloplasty. Overall, operative time ranged from 105 to 360 minutes (mean 145) for the laparoscopic group and 60 to 240 minutes (mean 156.6) for the open surgery group. Hospital stay and interval to return to regular preoperative activities were 2 to 6 days (mean 3.5) and 10 to 21 days (mean 16) for patients undergoing laparoscopic nephrectomy, which was significantly shorter than for those undergoing a flank procedure, 3 to 16 days (mean 8) and 35 to 84 days (mean 32.3), respectively. Pain medication requirements were also markedly decreased after laparoscopic nephrectomy. Of the patients in the laparoscopic group 2 experienced complications with only 1 requiring conversion to open nephrectomy. The laparoscopic technique is an effective as the flank approach for benign renal conditions, while providing a more rapid recuperation and superior cosmetic result.
