[Etiology and treatment of penoscrotal skin defects]

The influence of the type and extent of debridement on survival of patients with Fournier's gangrene and the efficacy of reconstruction with grafts and residual skin are analyzed.

The study comprised 43 patients; 35 Fournier's gangrene, 7 trauma and one tumor. The patients with gangrene were treated by debridement, drainage, amputation and antibiotics. Cutaneous grafts and residual skin were used to repair the defect in a second stage procedure. No testicular avulsion was found in the trauma cases. The penile and scrotal injuries were sutured. One burial and one local flap were performed in two penoscrotal avulsions. Skin from the penis was used to repair partial scrotal defects and grafts were applied on the penis.

Mortality (21%) was high in partially debrided Fournier's gangrene, penis amputation and in cases undergoing only drainage. Skin grafts for total loss of penoscrotal cover and penile skin flaps for partial scrotal defects achieved good results. Tension suture was unfavorable in the penis, but was well-tolerated in the scrotum. Burial and local skin flaps were not good solutions. Poor results were obtained by conserving residual skin and grafting only the defect.

Early, wide and repeated debridement procedures reduced the mortality in patients with gangrene, and the best results of reconstruction were obtained with split-thickness skin grafts for total loss of penoscrotal cover and penile skin flaps for partial defects of the scrotum.
