BILATERAL VARIATION OF RENAL ARTERY AND ITS CLINICAL SIGNIFICANCE IN NORTH INDIAN POPULATION

Abstract

Background: Classically each Kidney is supplied by a single renal artery originate from abdominal aorta. With the advent of laparoscopic renal surgeries and donor nephrectomies, it becomes mandatory for the surgeons to understand the abnormality or variations in the renal vasculature. The aim of present study is to highlight incidence of bilateral variations of renal artery in North Indian Population.
Material and Methods: The materials used for present study comprises 56 adult cadavers of both sexes (40 male and 16 female) from North Indian origin. During routine abdominal dissection conducted for medical undergraduates at Department of Anatomy, kidneys along with their arteries were explored and the morphological variations of renal arteries were recorded.
Results: We observed variations of renal arteries in 22 cadavers (39.2%). Bilateral variation were present in 12 cadavers (21.4 %%), unilateral in 10 cadavers (17.8%). The unilateral variation was present right side in 3 cadavers (5.3%) and left side in 7 cadavers (12.5%).
Conclusion: Awareness of bilateral variations of renal artery is necessary for surgical management during renal transplantation; repair of abdominal aorta aneurysm, urological procedures and for angiographic interventions.
