Impalement injury of the urinary bladder: a case report

Impalement injury of the urinary bladder, especially secondary to rectal impalement, is extremely rare. In this case, a 31-year-old man sustained a steel pipe impalement injury through his perirectal region. He presented with gross hematuria, abdominal defense, and a penetrating wound. On the basis of the computed tomography findings and abdominal defense, we suspected a through-and-through bladder perforation from the rectal space to the intraperitoneum. Laparotomy revealed a through-and-through bladder perforation as well as damage to the right ureter, 3 distinct ileal injuries, and rectal anterior, anal, and right seminal vesicle injuries. Surgical repair of each damaged site was undertaken. The prompt diagnosis and surgical repair ensured good postoperative recovery.
