Renal arteries show a range of variations in origin and distribution to the kidney, with variable distributions and caliber of the vessels on each side. As these have serious implications in transplant surgery and renal imaging, it is imperative to examine the variations possible and also to have a common nomenclature for the variations seen. Standard textbooks note that variations are seen in about 30% of the population with a range of 9-76%1 and hence it was deemed necessary to add to the existing knowledge of variations in the patterns of the renal artery. 3 kidneys with variable arterial supplies have been described and the variations have been discussed here. A review of literature also showed that the nomenclature of the arteries varied from one study to another. An attempt has been made here to rationalize the terminology for ease of discussion and comparison.
