Exposure of the kidneys and the renal vessels were done following the standard dissection procedures. Variations of the renal arteries were observed carefully and recorded. Results: The accessory renal arteriess observed in the present study (24%) were grouped under the types 1 to 7 following the earlier classification [1] Type 1 was found bilaterally in a male and in a female cadaver. Type 2 was found unilaterally in a male cadaver on the right side. Type 3 was found unilaterally in a female cadaver on the right side. Type 7 was found bilaterally in a male and in a female cadaver and unilaterally in 2 male cadavers on the left side. Conclusion: The knowledge of these variations provides safety guidelines for endovascular procedures like therapeutic embolization and angioplasties. The knowledge of variations reported here is very useful for radiologists, urologists and surgeons
