Abstract： @@ Penetrating wound of the anal canal is relatively rare, which is often complicated with injuries of the rectum, urinary bladder or posterior urethra. Misdiagnosis and improper treatments of the disease may lead to pelvic abscess, anal stenosis, fecal incontinence, or rectovesical fistula. From 1985 to 2004, 16 patients with penetrating wounds through the anorectum and urinary bladder or posterior urethra were treated in our hospital.
