Ureteral Obstruction Caused by Crohn's Disease / 대한비뇨기과학회지

ABSTRACT

Obstructive uropathy with hydronephrosis is a well-known complication of Crohn's disease. This complication is treacherous, since symptoms of urinary tract disease are mostly absent. Inflammatory ureteral engagement should always be suspected in patients with Crohn's disease, particularly when located in the terminal ileum. The treatment for this condition is still controversial. We report a case of a 25 year-old man who presented with intermittent diarrhea, weight loss, and RLQ pain. Diagnostic studies confirmed Crohn's disease, and revealed an abdominal mass obstructing the right ureter with hydroureteronephrosis. The patient was successfully treated with corticosteroid and mesalamine, without resection of the ileocecal lesion, drainage of the iliopsoas abscess and ureterolysis. We discuss a ureteral obstruction as a complication of Crohn's disease, with emphasis on conservative treatment.
