Background: Classically, a single renal artery supplies each kidney after originating from abdominal aorta. Presence of accessory renal arteries are the most commonest variation of renal arterial supply.
Aims: The present cadaveric study was undertaken with the aim to study the incidence of accessory renal artery and to correlate these variations with their embryological and clinical perspective.
Material and Method: Material of this study comprised of 40 formalin fixed adult human cadavers (80 sides) irrespective of sex. These were dissected during routine abdominal dissection conducted for undergraduate medical students at the department of anatomy. The kidneys with their arteries were explored and traced up to their origin from abdominal aorta or any other source. The morphological variations of renal arteries were noted and photographed.
Results: We observed supernumerary renal arteries in 12/40 (30%) cases (20% of aortic origin, 7.5% of renal origin and 2.5% of superior mesenteric origin) on the right side and 15/40 (37.5%) cases (27.5% of aortic origin and 10% of renal origin) on the left side. Supernumerary renal arteries  were observed to be entering the kidney through hilum, superior pole, and inferior pole.
Conclusions: Awareness of variations of renal artery is necessary to prevent catastrophes during   several surgical interventions such as renal transplantation, abdominal aortic aneurismal repair and urological procedures and for angiographic interventions.
KEY WORDS: Supernumerary Renal Artery, Accessory Renal Artery, Hilum, Variations.
