UNILATERAL TRIPLE RENAL VEINS AND BILATERAL DOUBLE RENAL ARTERIES- AN UNIQUE CASE REPORT

A precise knowledge of the vascular variations of human kidney is essential for the surgeon and radiologist to avoid complication during interventional radiological procedure, renal transplantation, renal trauma and other urological procedures. The present case report is regarding unilateral variation of renal vein and bilateral variation of renal artery. During routine cadaveric dissection of abdominal region, we observed three renal veins in right kidney. All right renal veins were emerging from hilum of kidney and drained in inferior vena cava where as in left Kidney venous drainage is normal. In right Kidney both main and accessory renal artery arose from abdominal aorta. Left main renal artery arose from abdominal aorta with left accessory renal artery arising from left middle suprarenal artery which is branch of coeliac trunk. In this case right ureteropelvic junction is seen to be compressed in between right accessory renal artery and right lower renal vein which crossed anteriorly with right middle renal vein crossing posteriorly this condition may cause hydronephrosis. The above finding to be reported in a single case is rarely seen. This is a valuable contribution from anatomical knowledge to operative procedures.
