Background: The use of grafts with multiple renal arteries (MRA) in renal transplantation has not been clearly established.
Material/Methods: A systematic literature review used predefined terms to search PubMed, EMBASE, and the Cochrane Library for all studies since 1985 that included more than 50 MRA grafts. A total of 23 studies, comprising a total of 18,289 patients, were eligible to be included in the meta-analysis.
Results: Patients who received an MRA graft compared to single renal artery (SRA) grafts showed significantly higher complication rates (13.8% vs. 11.0%, OR 1.393, p
Conclusions: MRA grafts were associated with a higher risk of complication and delayed graft function but had comparable long-term outcomes for graft and patient survival.
