Aim & Objectives: To evaluate main renal artery dimensions. The main renal artery (MRA) diameter provide indirect evidence of accessory renal arteries (ARA). Materials and Methods: 60 well embalmed cadavers from the Department of Anatomy, Stanley Medical College were included in this study. Dissection is through Conventional Dissection Method. Results: Of the 60 cadavers 72% had Mean Renal Artery diameter of more than 4mm. 28% had less than 4mm. But in each of the 28% of cadavers the kidneys were supplied with an accessory renal artery arising directly from the abdominal aorta. Conclusion: Multiple renal vascular variations are present in screening of normal patients and a sound knowledge of possible variations is very useful for radiologists, urologists and surgeons in general which prompted us to undertake this study.
