Impalement injury to both the urinary bladder and the rectum is a rare occurrence. A 45-year-old man was referred to our hospital because he had been stabbed through the internal femoral skin by a steel bar. Retrograde cystography and computed tomography failed to demonstrate bladder rupture. We carried out cystoscopy (CS) because of the existence of gross hematuria and found a penetrating wound in the posterior wall. Colon fiberscopy revealed two wounds in the rectum, one of which communicated with the bladder. A diagnostic laparoscopy revealed no associated injuries in the peritoneal cavity. Vesicorectal injury was diagnosed and treatment included transanal closure of fistulas and indwelling ureteral and urethral catheters. Postoperative CS revealed complete closure of the injury.
