Horseshoe kidney
Horseshoe kidney
Horseshoe kidney, also known as ren arcuatus, is a relatively common congenital kidney malformation. In this condition, the kidneys on both sides of the body fuse at one end, forming a horseshoe-shaped (U-shaped) structure, hence the name horseshoe kidney. In most patients with this condition, the lower poles of the kidneys are fused, while in a smaller proportion, the upper poles are fused. If this condition does not cause complications, it generally does not present with obvious symptoms.
