Composite gastric seromuscular and omental pedicle flap for urethral and scrotal reconstruction after Fournier's gangrene.

A new composite gastric seromuscular and omental pedicle flap is described that can provide immediate airtight or watertight closure in the repair of complex defects involving the urethra. This flap was used to repair defects of the urethra, scrotum, and abdominal wall in a patient with Fournier's gangrene. The seromuscular patch was sutured to the urethral defect, and the omentum was applied over the defects of the scrotum and abdominal wall. This new procedure made it possible to close the skin primarily without leakage or infection. The patient had an uncomplicated recovery. Postoperative urethrography demonstrated no leakage or stenosis.
