Abstract
Objectives: The objective of this study was to compare the long-term graft outcomes of left-versus-right donor nephrectomy with multiple renal arteries (MRAs), and therefore creating a reference for the expansion of the potential living kidney donor pool. Methods: Laparoscopic live donor nephrectomy cases between May 2010 and October 2020 were included in this retrospective cross-sectional study. The data relating to donor and recipient demographics, surgical and anatomical characteristics, recipient, and graft status were retrieved and compared using nonparametric statistical methods and multivariate regression. Analyses were fit for survival factors. Results: A total of 1,009 recipients were included in this retrospective cross-sectional study with their donors. 16.7% of the donors had been discovered to have more than one renal artery supplying the donated kidney. The acute rejection rate was 12.8%. Death-censored graft survival at postoperative year 5 for single renal artery (SRA) transplants was 89.6%, 89.5% for left-sided MRAs, and 88.2% for right-sided ones. Conclusions: Both right donor nephrectomy and left donor nephrectomy are safe procedures with no significant negatively impacted rates for neither survival nor complications of the recipients in the long-term, compared to SRA ones.
