Background
Although the procedure is generally safe, significant morbidity and even mortality have occurred after laparoscopic donor nephrectomy (LDN). The learning curves for both surgeons and institutions with LDN have not been well delineated, and longterm donor data are not well reported.Study Design
A retrospective study of the initial 512 patients undergoing LDN performed at Mount Sinai Medical Center between October 1996 and March 2006 was performed. Intraoperative and immediate postoperative surgical outcomes were reviewed. Univariate analysis and multivariate logistic regressions were performed to identify predictors of outcomes, including the experience level of individual surgeons and of the institution. Longitudinal followup data of donor patients between 1 month and 9 years were obtained.
Results
Mean donor age was 39.2 years, and 54.6 % of patients were women. Left kidneys were procured in 84.0 % . Operative time averaged 215.2 minutes, and warm ischemia time, 166.6 seconds. The conversion rate was 1.4 % , and hand-assistance was used in 49.9 % . The intraoperative complication rate was 5.5 % , 30-day complication rate 9.4 % , and 1.4 % of patients required reoperation. Immediate graft survival was 97.1 % , acute tubular necrosis occurred in 8.5 % , and delayed graft function in 3.7 % . At a mean followup of 37.2 months, delayed donor complications were infrequent, but included chronic pain, hypertension, incisional hernia, and small bowel obstruction. Although individual surgeons and our institution gained experience, operative and warm ischemia times decreased significantly, but complication rates were unchanged.
Conclusions
Although a learning curve was discovered for operative time and warm ischemia time, excellent results can be achieved during the early experience of both surgeons and institutions with LDN, and maintained over time. Younger, female, and nonobese donors were associated with fewer complications. Longterm donor morbidity is uncommon, but mandates better followup.
