Bilateral prehilar multiple branching of renal arteries: a case report and literature review.

ABSTRACT

Proper knowledge of variations of the arteries supplying the kidney is essential not only to the anatomists but also to the surgeons. In the present paper we are reporting a case of bilateral early and multiple branching of the renal arteries. The origin of the 2 renal arteries was normal but soon after their origin they ended by giving rise to multiple branches. Most of these branches entered the kidney through the hilum. However, on both sides, one of the branches (superior polar artery) passed superolaterally to reach the upper pole of the kidney. The superior polar artery also gave rise to the inferior suprarenal artery. Further, related literature review is done and the urological implications of these variations in renal surgeries are discussed.
