Anterior urethral injury.

Anterior urethral injuries, although rare, may be associated with substantial long-term morbidity. Urethral injuries that occur due to penetrating trauma or penile fracture are best treated by meticulous two-layer primary repair. Those that occur due to rapid deceleration injury are usually best treated by suprapubic diversion and delayed reconstruction because of associated injuries and concomitant contusion of the supporting spongiosum.
