Rupture of the corpus cavernosum of the penis.

Rupture of the corpus cavernosum ("fracture" of the penis) is an uncommon injury that occurs in an erect penis. The tunica albuginea is torn during coitus or as a result of external forces, resulting in sudden pain, swelling, and discoloration of the penis. Urethral rupture is associated with the cavernous injury in approximately 10% of cases. Treatment of the injury aims at full functional and cosmetic recovery. Nonoperative treatment results in a 10% incidence of penile deformity and requires a substantial hospital stay. However, surgical repair eliminates resultant deformity and allows for earlier hospital discharge. Three patients had fractured penises, including one penis associated with a torn urethra. Early surgical repair was performed in each patient, and the results were excellent. Prompt surgical repair should be given to all patients with a fractured penis.
