In this disorder, the patient's [[kidney]]s 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. ==Presentation== In patients with this disorder, the central portion of the kidney will be found just inferior to the [[inferior mesenteric artery]] because its embryologic ascent is arrested by its presence. Persons affected by this disease may experience [[nausea]], abdominal discomfort, [[kidney stones]] and [[urinary tract infection]]s. There is currently no cure for renal fusion other than symptomatic treatment. ==Associated conditions== While most cases of horseshoe kidneys are asymptomatic and discovered upon autopsy, the condition may increase the risk for: *Kidney Obstruction - abnormal placement of ureter may lead to obstruction and dilation of the kidney. *Kidney Infections - associated with [[vesicoureteral reflux]]. *Kidney Stones - deviant orientation of kidneys combined with slow urine flow and kidney obstruction may lead to kidney stones. *Kidney Cancer - increased risk of renal cancer, especially [[Wilm's tumor]], [[transitional cell carcinoma]], and [[carcinoid tumor]]. Despite increased risk, the overall risk is still relatively low. The prevalence of horseshoe kidneys in females with [[Turner Syndrome]] is about 15%.<ref name="pmid10862660">{{cite journal |author=Kleta R, Brämswig JH |title=Horseshoe kidney and Turner syndrome |journal=Nephrol.
