Management of Penile Amputation Injuries
Penile amputation is an uncommon injury resulting from self-mutilation, felonious assault, or accidental trauma. Management requires resuscitation and stabilization of the patient with particular attention to underlying psychiatric illness. Amputated tissue can be preserved under hypothermic conditions in preparation for surgical replantation. Current replantation techniques rely on microsurgical approximation of the dorsal structures and cavernosal arteries with uniformly good results. Phallic replacement may be necessary when the amputated segment is lost. Microsurgical free forearm flap phalloplasty is the current mainstay of penile replacement surgery. Although urethral complications remain problematic, the results continue to be acceptable with regard to appearance and function. A unique subset of patients sustaining amputation injury is children. Both replantation and phallic construction have been successful in children and represent an alternative to gender reassignment.
