title: Left hydronephrosis caused by Crohn disease successfully treated conservatively.
abstract: We report the case of a 35-year-old man who presented with fever, diarrhea, and a left abdominal mass. Diagnostic studies confirmed Crohn disease and revealed an abdominal mass obstructing the left ureter with hydroureter and hydronephrosis. The patient was successfully treated conservatively, with corticosteroids and mesalamine, A review of the literature indicates a predominance of right ureteral involvement in Crohn disease, associated with a high incidence of ileocecal disease. Most of these patients were treated surgically, with resection of ileocecal lesion and/or ureterolysis. Ureteral obstruction as a complication of Crohn disease is discussed, with emphasis on conservative treatment.
