Traumatic urethrocavernous fistula may develop as an acute or late complication after blunt penile trauma, however reports on corpus spongiosum-cavernosum fistula have rarely been described. We report the case of a 24-year-old man with a corpus cavernosum-spongiosum fistula secondary to an untreated penile fracture, and it surgical management with acellular matrix graft. Penile fractures are urologic emergencies that, if not handled opportunely, can lead to serious sequels, early surgical management should be the treatment of choice. The appearance of a post-traumatic cavernospongous fistula is a rare complication with almost non-existent literature reported. However, ignorance of this pathology can significantly compromise the patient's quality of life.
