Abstract:
Urethral foreign bodies are relatively rare. When seen, they are usually the result of entry via the urethral meatus. Several reports in the literature have documented the passage of retained bullets into the genitourinary system. The vast majority of these were ultimately expelled spontaneously via the urethra. Very few cases of urethral obstruction and accompanying urinary retention due to bullet migration have been described. The presented case details distal urethral obstruction due to the migration of a retained firearm projectile presenting 1 month after initial gunshot wound. No such case exists in the emergency medicine literature.
