Purpose: We compared postoperative complications of laparoendoscopic single site and standard laparoscopic living donor nephrectomy using a standardized complication reporting system. Materials and Methods: We retrospectively analyzed the records of consecutive patients who underwent a total of 663 laparoscopic living donor nephrectomies and 101 laparoendoscopic single site donor nephrectomies. All data were recorded retrospectively. The 30-day complication rate was compiled and graded using the modified Clavien complication scale. Multivariate binary logistic regression was used to determine independent predictors of complications. Results: Baseline demographics were comparable between the groups. Compared to those with laparoscopic living donor nephrectomy patients who underwent laparoendoscopic single site donor nephrectomy had a shorter hospital stay and less estimated blood loss but longer operative time (p <0.05) as well as higher oral but lower intravenous in hospital analgesic requirements (p <0.05). Mean warm ischemia time was marginally lower in the laparoendoscopic single site donor nephrectomy group (3.9 vs 4 minutes, p = 0.03). At 30 days there was no difference in the overall complication rate between the laparoscopic living and laparoendoscopic single site donor nephrectomy groups (7.1% vs 7.9%, p >0.05). There were 8 major complications (grade 3 to 5) in the laparoscopic living donor nephrectomy group but only 1 in the laparoendoscopic single site group. Multivariate binary logistic regression analysis revealed that estimated blood loss was a predictor of fewer complications at 30 days. Conclusions: With appropriate patient selection and operative experience laparoendoscopic single site donor nephrectomy may be a safe procedure associated with postoperative outcomes similar to those of laparoscopic living donor nephrectomy as well as low morbidity. Using a standardized complication system can aid in counseling potential donors in the future.
