Horseshoe kidney, also known as renal fusion, is a congenital disorder affecting about 1 in 400 people[1]. In this disorder, the patient's kidneys fuse together to form a horseshoe-shape during development in the womb.
Fusion abnormalities of the kidney can be categorized into two groups: horseshoe kidney and crossed fused ectopia. The horseshoe kidney is the most common renal fusion anomaly.
