Purpose:
Living donor kidneys with multiple arteries are routinely procured laparoscopically. We aim to present our experience with laparoscopic donor nephrectomy (LDN) and to compare the graft function and outcome between cases with single versus multiple arteries.
Methods:
We compared the demographic data, operation time, warm ischemia time, rejection rate, and graft function between LDN kidneys with single artery and those with multiple arteries.
Results:
Seventy-three cases with 1 renal artery (group LDN-1), 8 cases with 2 renal arteries (group LDN-2) and 5 cases with 3 or more renal arteries (group LDN-3) were included in the study. The mean operative time was significantly higher in groups LDN-2 (100.3 ± 9.5 minutes) and LDN-3 (120.6 ± 10.3 minutes) compared to group LDN-1 (75.7 ± 10 minutes, P < 0.001). Similar results were detected with respect to the warm ischemia time. There were no statistically significant differences related to graft function and outcome among these groups.
Conclusion:
Multiple renal arteries present a special challenge in both donor nephrectomy and renal transplantation. However, laparoscopic procurement of a kidney with multiple renal arteries, regardless of the number, is reliable and has no significant impact on the graft outcome.
