The treatment of external genitalia trauma is diverse according to the nature of trauma and injured anatomic site. The classification of trauma is important to establish a strategy of treatment; however, to date there has been less effort to make a classification for trauma of external genitalia. The classification of external trauma in male could be established by the nature of injury mechanism or anatomic site: accidental versus self-mutilation injury and penis versus penis plus scrotum or perineum. Accidental injury covers large portion of external genitalia trauma because of high prevalence and severity of this disease. The aim of this study is to summarize the mechanism and treatment of the traumatic injury of penis. This study is the first review describing the issue. 1. Introduction injury by anatomical location [4].

The primary mechanism of this injury is an diverse: from infections to disfigurement or partial to total abrupt, blunt trauma by forceful bending of the erect penis amputation of the penis. over the pubic bone or perineum [28]. For sexual causes, vigorous intercourse and masturbation were reported [28– Gee et al. reported the postoperative complication rate 30] and, for nonsexual causes, falling off from bed, placing as 0.2–0.6%, which ranges from bleeding, lymphedema, an erect penis in the underwear, and spontaneous fracture fistula formation, and iatrogenic hypospadias to the partial during urination were reported [28–31].
