Penile Fracture and Trauma

Background

Traumatic penile injury can be due to multiple factors. Penile fracture, penile amputation, penetrating penile injuries, and penile soft tissue injuries are considered urologic emergencies and typically require surgical intervention.

The goals of treatment for penile trauma are universal: preservation of penile length, erectile function, and maintenance of the ability to void while standing.

Traumatic injury to the penis may concomitantly involve the urethra. Urethral injury and repair is beyond the scope of this article but details can be found in Urethral Trauma.

Penile fracture

Penile fracture is the traumatic rupture of the corpus cavernosum. Traumatic rupture of the penis is relatively uncommon and is considered a urologic emergency.

Sudden blunt trauma or abrupt lateral bending of the penis in an erect state can break the markedly thinned and stiff tunica albuginea, resulting in a fractured penis. One or both corpora may be involved, and concomitant injury to the penile urethra may occur. Urethral trauma is more common when both corpora cavernosa are injured.

Penile rupture can usually be diagnosed based solely on history and physical examination findings; however, in equivocal cases, diagnostic cavernosography or MRI should be performed. Concomitant urethral injury must be considered; therefore, preoperative retrograde urethrographic studies should generally be performed.

Penile amputation

Penile amputation involves the complete or partial severing of the penis. A complete transection comprises severing of both corpora cavernosa and the urethra. Amputation of the penis may be accidental but is often self-inflicted, especially during psychotic episodes in individuals who are mentally ill.

Penetrating injury

Penetrating injury is the result of ballistic weapons, shrapnel, or stab injuries to the penis. Penetrating injuries are most commonly seen in wartime conflicts and are less common in civilian medicine. Penetrating injuries can involve one or both corpora, the urethra, or penile soft tissue alone. 

Penile soft tissue injury

Penile soft tissue injury can result through multiple mechanisms, including infection, burns, human or animal bites, and degloving injuries that involve machinery. The corpora, by definition, are not involved.
