Synopsis

A congenital abnormality in embryogenic migration that results in fusion of one pole of each kidney with the other. Typically, affected individuals are asymptomatic and diagnosis is made incidentally. Horseshoe kidney carries increased risk of hydronephrosis, nephrolithiasis, and urinary tract infection due to abnormalities in ureter position which may lead to vesicoureteral reflux or ureteropelvic junction obstruction.
