Laparoscopic live donor nephrectomy: the University of Maryland 3-year experience.

PURPOSE

We determined whether laparoscopic living donor nephrectomy decreases the morbidity of renal donation for the donor, while providing a renal allograft of a quality comparable to that of open donor nephrectomy.

MATERIALS AND METHODS

In a 3-year period laparoscopic donor nephrectomy was performed via the transperitoneal approach. We evaluated donor and recipient medical records for preoperative donor characteristics, intraoperative parameters and complications, and postoperative recovery and complications.

RESULTS

Of the 320 laparoscopic donor nephrectomies performed the left kidney was removed in 97.5%. Intraoperative complications, which developed in 10.4% of cases, tended to occur early in the experience and required conversion to open nephrectomy in 5. Average operative time was 31/2 hours and warm ischemia time was 21/2 minutes. As the series progressed, blood loss as well as laparoscopic port size and number decreased but extraction site size remained constant at 7 cm. Urinary retention, prolonged ileus, thigh numbness and incisional hernia were the most common postoperative complications. Postoperative analgesic requirements were low and average hospitalization was 66 hours.

CONCLUSIONS

Laparoscopic donor nephrectomy appears to be safe and decreases morbidity in the renal donor. Allograft function is comparable to that in open nephrectomy series. The availability of laparoscopic harvesting may be increasing the living donor volunteer pool.
