Dorsal urethral fistula: case report and review of literature.

Urethral fistula is a rare, but recognized, entity. We report the case of a young diabetic patient who developed urethral fistula on the dorsum of penis after debridement for necrotizing fasciitis. This cause and location for urethral fistula is extremely rare, and we were unable to find a similar case in published studies. A brief literature search for various causes of urethral fistula was made, and the likely mechanisms for the cause of the fistula were explored.
