Right ectopic kidney with rare vascular variations

During routine dissection of 73-year-old adult male cadaver, multiple variations were found in the right kidney. The right kidney was located at the level between fourth lumbar vertebra and second sacral vertebra. There was a superior polar artery, and the right renal artery emerged from the left side of the abdominal aorta at the level of fourth lumbar vertebra. There were two renal veins. The vein from superior pole of the kidney drained into the inferior vena cava. The renal vein from the hilum of the right kidney had a long course along the left side of the abdominal aorta and joined with the left suprarenal vein behind the left renal vein and drained into the left renal vein. Knowledge regarding the variations in renal vessels is very important for urologists and interventional radiologists.
