[Late-onset urethrorectal fistula after laparoscopic radical prostatectomy: report of a case].

Urethrorectal fistula is a relatively rare disease. The most frequent cause of acquired urethrorectal fistulas is known to be iatrogenic complications, such as rectal injuries during the prostate operations. Rectal injuries are usually noticed during the operation and the majority can be repaired in situ. We report a case of late-onset urethrorectal fistula that lacked obvious rectal injury during the operation. Ischemic change or heat denaturation of rectal wall may be the potential cause of the present urethrorectal fistula.
