Purpose: Performing laparoscopic nephrectomy in the setting of previous renal surgery may be challenging and associated with a higher complication rate. We conducted this study to assess the feasibility and safety of laparoscopic nephrectomy among patients with a history of ipsilateral renal surgery. Patients and Methods: We reviewed the chart of 193 patients who underwent transperitoneal laparoscopic nephrectomy for nonfunctioning kidney between April 2007 and March 2011. The study population was divided into two groups: Group 1 comprised 37 patients with a history of ipsilateral renal surgery, and Group 2 consisted of 156 patients with no history of previous renal surgery. Results: Baseline characteristics and preoperative variables were similar in both groups. Mean operative time, complication rate, and hospital stay were comparable between the two groups. A nonstatistically significant trend toward a higher transfusion rate was noted in Group 1 patients. The operation was converted to open nephrectomy in 1 (2.7%) and 3 (1.9%) patients of Groups 1 and 2, respectively (P=.765). Conclusions: Laparoscopic nephrectomy of the nonfunctioning kidney is a feasible and safe procedure in the setting of previous renal surgery and is not associated with a significant increase in operative time and complication rate compared with patients with no prior ipsilateral renal surgery. © Copyright 2012, Mary Ann Liebert, Inc. 2012.
