Laparoscopic procurement of single versus multiple artery kidney allografts: Meta-analysis of comparative studies.

ABSTRACT

Laparoscopic donor nephrectomy has become the standard procedure to procure kidney graft. Transplantation using multiple arteries allograft is technically more challenging and still controversial with respect to renal transplantation outcomes. The objective of this study was to examine the transplantation outcome in both donor and recipient outcome of multiple arteries allograft kidney compared with single renal artery kidney. Eligible studies were identified from electronic databases PubMed, Cochrane CENTRAL, Science Direct, and CINAHL as of October 2016. Relevant parameters explored using Review Manager V5.2 included donor and recipient outcomes. Twenty-four studies were included in this meta-analysis. Compared with SA, MA kidneys were associated with a longer donor operative time. There was no difference between donor length of stay, intraoperative blood loss, hospital stay, first warm ischemic time (WIT-I), and donor surgical complications in donors with multiple arteries compared with single. There was an increased risk of one-year graft loss (OR 1.57, 95% CI 1.09 to 2.26, p = 0.016), recipient vascular complications and recipient ureteral complications in multiple arteries compared with single artery allografts. Kidney transplantation with multiple arteries is relatively as safe as single artery in terms of donor outcomes. However, transplantation with multiple arteries allograft had several potential negative impacts on the recipient outcomes.
