An unusual case of unilateral additional right renal artery and vein

Proper knowledge of variations of the vessels of the kidney is essential to the radiologists and surgeons. One such variation was observed in a 65-year-old male cadaver at AIMST University, Kedah, Malaysia. The dissection of the abdomen revealed an additional renal artery and an additional renal vein on the right side. In addition to the normal right renal artery, an additional renal artery branched from the ventral side of abdominal aorta and passed laterally to enter into the kidney through the lower part of its hilum. The additional right renal vein emerged from the lowermost end of the hilum, passed medially below the additional renal artery to end in the inferior vena cava below the opening of normal right renal vein. Further, related literature review is done and the urological implications of these variations in renal surgeries are discussed.
