Abstract
The renal artery when it reaches close to the hilum of kidney where it cleaves into anterior and posterior divisions were receives around 75% and 25% of blood respectively. Further these branches divide into many segmental branches. These segmental arteries does not have collateral system, so when there is any occlusion of these arteries which results in the ischemia of the particular segment of kidney. Anatomists believe that knowledge of presence of lower polar artery is essential for polar nephrectomy. Prior knowledge of variations in the renal vessels is required for urological surgery for preoperative investigations as there are reports of surgical complications which include enormus haemorrhage. In this study we analyzed the different variations in the intra renal branch of inferior segmental artery.
