Presence of anomalous structures has been continually observed in human body specimens. Such variations have been observed in renal vasculature. During routine dissection of a young adult male cadaver at the Dissection Hall of the Anatomy Department of Enugu State University of Science and Technology, College of Medicine, Parklane, GRA, Enugu, Nigeria, we found multiple renal vasculatures. There were four separate renal arteries arising directly from abdominal aorta on the left. On the right, one major artery gives an early branch and three branches close to the hilum before separately entering the renal parenchyma. The venous vasculature also displays an obvious variation of a bifurcated vein on the right and a normal single vein on the left. These may predispose to easy factors of partial occlusion or compression of renal vasculature resulting in varicocele or hypertension. Similarly, blood circulation through the renal arteries, in case of multiple branching pattern, may result in altered hemodynamics. The knowledge of these anomalous vasculatures is significant since it is known that microvascular techniques for renal transplantation surgeries require a thorough anatomical knowledge of accessory or multiple vasculatures for better outcomes.
