Laparoscopic Donor Nephrectomy Is a Safe Surgical Approach in Healthy Obese Kidney Donors: A 10-Year Single-Center Retrospective Study.

OBJECTIVES

A lack of donors continues to be a significant problem. Kidney donors with a body mass index ≥ 30 kg/m² are not suitable for laparoscopic donor nephrectomy; however, some studies have suggested that an obese donor could be an appropriate donor with similar surgical outcomes. Here, we report the results of our 10-year experience of laparoscopic donor nephrectomy, examining the effects of body mass index on the surgical results of laparoscopic donor nephrectomy.

MATERIALS AND

METHODS

We retrospectively reviewed medical records of patients who underwent laparoscopic donor nephrectomy at the Shahid Beheshti University Medical Science, Urology Center (Tehran, Iran) from 2005 to 2015. The collected information included pretransplant and posttransplant serum levels of hemoglobin and creatinine. We also collected data on surgical outcomes (operation time, cold and warm ischemia, need for blood transfusion, and conversion to open surgery, length of hospital stay, and complication rates) with respect to body mass index categories (≤ 24.9, 25-29.9, and ≥ 30 kg/m²).

RESULTS

Of 1083 kidney donors, 732 donors had body mass index of ≤ 24.9 kg/m², 256 had body mass index between 25 and 29.9 kg/m², and 95 had body mass index of ≥ 30 kg/m². Differences among groups were not significant in terms of operation time (P = .558), warm or cold ischemic time (P = .829 and .951, respectively), blood transfusion (P = .873), and length of hospital stay (P = .850).

CONCLUSIONS

The laparoscopic approach for donor nephrectomy is a safe and effective method in obese donors without significant postoperative complications.
