Concurrent variations of the left renal and gonadal vessels: a case report.

A thorough knowledge of vascular variations in the vicinity of the kidney is essential due to the increased number of kidney transplants, more so on the left side because the donor's left kidney is preferred for transplantation. We found multiple vascular variations in the vicinity of the left kidney, which were noted during routine dissection classes. The left renal artery arose from the abdominal aorta and supplied the left kidney in a usual manner. There was an additional left renal artery, which took its origin from the abdominal aorta, below the origin of the inferior mesenteric artery. This artery was accompanied by an additional renal vein, which drained into the left common iliac vein. On the left side, there were two testicular veins. Knowledge of these abnormal vessels can be useful during radiological and surgical procedures in cases of nephrectomies, renal tumors, transplants, and renal vascular illnesses.
