Pyeloureteral Jonction upon a Horseshoe Kidney

Abstract

The horseshoe kidney is the most common renal fusion anomaly, affecting around 0.25% of the general population. We report the rare case of a 14-year-old child with a horseshoe kidney, admitted to hospital for chronic abdominal pain and burning micturition. Physical examination revealed umbilical tenderness. Abdominal ultrasound showed a horseshoe kidney associated with moderate bilateral hydronephrosis. CT scan revealed fusion of the kidneys at their lower poles and obstruction of the ureteropelvic junction (UPJ).
