Abstract: This study is aimed to determine the variations in perihilar branching pattern and extra renal arteries in 25 cadavers at SRM medical college hospital and research center, Chennai, India. Among the 50 kidneys studied, perihilar branching pattern (32%), accessory renal artery (26%), polar renal artery (16%), accessory renal artery & perihilar branching pattern (12%), accessory renal artery & polar artery (10%) and polar renal artery & perihilar branching pattern (4%) were observed in 16, 13, 8, 6, 5 and 2 cases, respectively. The knowledge of these probable variations of renal arteries will be useful for surgical management during renal transplantation, angiographic interventions, urological procedures and repair of abdominal aorta aneurysm.
