Background: We investigated the safety and effectiveness of routine harvest of the left kidney for renal transplantation regardless of the presence of multiple renal arteries to obtain the longer renal vein.
Patients and methods: Between February 2000 and July 2008, 325 patients underwent left hand-assisted laparoscopic living donor nephrectomy. The true renal arterial anatomy as evaluated intraoperatively was compared with the renal arterial anatomy by computed tomography (CT). We compared the results for the patients with a single renal artery (group I) with the patients with multiple renal arteries (group II) in terms of the donor and recipient outcomes.
Results: Multiple renal arteries in left kidney were identified in 86 patients (26.5%). Thirty-seven CTs (11.4%) were in discord with the renal arterial anatomy evaluated intraoperatively. There was no difference in age, gender, body mass index, estimated blood loss, complication rate, or length of hospital stay between the 2 groups in the donor. Although the warm ischemic time and the operation time were significantly longer in group II (P = .008 and .001), overall graft survival was similar between the groups.
Conclusion: Routine harvest of the left kidney can be performed safely and effectively for the donor and recipient, even in the presence of multiple renal arteries.
