Introduction: The right and left kidneys receive their blood supply from the lateral branches of the abdominal aorta that is, respectively, from the right and the left renal arteries. The study of renal arteries is thus very important, but the literature shows a scarcity of data for the Indian population. This study was, therefore, planned to compare the morphometry of human renal arteries in cadavers and in computed tomography scans. Material and Methods: The study was conducted on 36 formalin-fixed cadavers and on 36 computed tomographic scans of renal arteries. The various parameters measured included the length of renal arteries, internal diameter of renal arteries at its origin, the vertical distance between the renal arteries at its origin and the point of bifurcation of the aorta, and vertical distance between the origins of the right and left renal arteries. Results: The length of the right renal artery was more than the left renal artery, there was no difference in the internal diameter of both the vessels at their origin and no difference in the vertical distance between the site of origin of renal arteries and bifurcation of Aorta. Discussion and Conclusion: The information of the right renal artery being longer than the left kidney confirms with the data available in the literature. The vertical distance between the origins of the renal artery and bifurcation of the aorta is important as it aids the radiologists for performing angiography. Furthermore, the data from this study would aid and supplement the preexisting data for the surgeons during renal transplantations.
