Abstract
Most frequently encountered renal vascular anomalies are the presence of supernumerary renal vessels. Thorough
knowledge of the renal vascular anatomy and its variants is essential for pre-operative planning. Renal arterial anomalies
are more common on the left side and venous anomalies on the right side. An incidental finding of supernumerary renal
vessels in a male patient undergoing multidetector computed tomography angiography is presented here. Three right renal
veins, independently emerging from the hilum and draining into inferior vena cava, were observed. The reported incidence
of this variant varies from 1.0 % to 4.5 %. The single left renal vein was having the normal preaortic course. Left kidney
received two renal arteries and the right kidney three renal arteries. The lower two right renal arteries had an anomalous
precaval course to reach the right kidney. Presence of bilateral multiple renal arteries associated with supernumerary right
renal veins is rarely reported.

Key words: Supernumerary renal vessels, Triple right renal veins, Precaval right renal artery, Renal vascular variation
