[Subacute intestinal obstruction caused by giant bladder diverticulum].

A case of a patient affected with intestinal obstruction of 4 days of evolution is presented. The diagnosis of giant bladder diverticulum due to Benign Prostatic Hypertrophy was made by abdominal ultrasound at Emergency Room, and afterwards was confirmed by cystography. A trabeculated wall and a diverticulum at the posterior side was seen with the cystography. The diverticulum full of urine couldn't be emptied due to a narrow diverticular neck and the rectum was obstructed. When a urethral catheter was put in, the symptoms of intestinal obstruction disappeared 800 ml of urine were passed through the catheter and the rectum compression was released; the gas was allowed to pass through the bowel and it's seen in plain X-Ray. This case is presented, considering its unusual this way of presentation of a giant bladder diverticulum. We have reviewed the literature en Medline since 1966 and we have not found a similar case.
