A case of Crohn's disease with hydronephrosis caused by ureteropelvic junction obstruction.
Ureteral obstruction is a rare extraintestinal manifestation of Crohn's disease (CD). We report the case of a 20-year-old man who presented with fever, diarrhoea, and lower abdominal pain. Diagnostic studies confirmed CD and revealed an abdominal mass obstructing the right ureter and hydronephrosis. Ureteropelvic junction (UPJ) obstruction was diagnosed. Despite an elemental diet and mesalazine therapy, the hydronephrosis persisted, and the patient eventually required surgery. Successful laparoscopic pyeloplasty was performed. This is the first report of CD associated with UPJ obstruction. Ureteral obstruction as a complication of CD is discussed.
