Meckel's diverticulum: a vesico-diverticular fistula.

On examination she was pyrexial (37.5°C) with tenderness in the right iliac fossa but no guarding or rebound tenderness; rectal examination revealed no abnormality. A provisional diagnosis of right ureteric colic seemed substantiated by finding blood in the urine; however, intravenous pyelography showed no stone or other renal pathology. Initial urine examination showed large numbers of pus cells but no growth on culture. Her symptoms failed to settle and a barium enema demonstrated extensive diverticular disease of the descending and sigmoid colon.
