"Horseshoe kidney" in an ectopic position. A case report.

We present a case study of a horseshoe kidney, harvested from a 68-year-old patient who died suddenly from rupture of an aneurysm of the ascending aorta. The kidney was ectopically placed, its isthmus corresponding to the terminal aorta. The two kidneys were unequal in size, the right kidney being larger than the left. We discovered four renal arteries, two on the right and two on the left side, and four renal veins, one left, one middle and two on the right side. The isthmus was blood supplied by the left and the right inferior renal arteries while the venous blood was collected by the left and middle renal veins.
