Triple Renal Arteries in a Cadaveric Kidney Donor: A Case Report.

Variation in the number of renal arteries is rare and is the most frequent and clinically important variation in the renal vascular system. Typically, this variant represents an immature form of complicated development of the renal arteries resulting from the persistence of more than one mesonephric artery during the transition period from mesonephros to metanephros in embryogenesis. The knowledge of this anatomical variation will allow the best healthcare to be provided for patients undergoing kidney surgical procedures and may reduce or eliminate avoidable postoperative complications. Although a double renal artery consists of a common anatomical variation, three or more arteries in a single kidney is less common. Herein, we report a case of a 42-year-old healthy cadaveric donor whose left kidney was found to have three renal arteries.
