Maximizing renal artery length in right laparoscopic donor nephrectomy by retrocaval exposure of the aortorenal junction

Laparoscopic donor nephrectomy (LDN) has become the standard of care at increasing numbers of renal transplant programs worldwide. As in open donor nephrectomy, the left kidney hits remained the preferred organ for LDN because of the greater renal vessel lengths. Currently, the overwhelming majority of donor operations are performed on the left kidney. This disparity may be due to an unfamiliarity with the technique of right LDN and technical difficulties encountered in obtaining adequate arterial and venous vessel lengths. Modifications in the laparoscopic technique have increased the length of the renal vein obtained from either side; however, further techniques are needed to maximize the length of the right renal artery in LDN. Herein the authors present a technique to provide exposure of the right aortorenal junction that provides maximal length of the right renal artery. This technique has currently been used in 20 consecutive right LDN operations without vascular complications or technical graft losses.
