[Endoscopic treatment for urethral stricture and obstruction in pediatric patients. Report of three cases].

Endoscopic surgery has been performed widely for treatment of urethral strictures in adults. However, recent advances in endoscope techniques also allow us to practice endoscopic surgery in pediatric patients. We recently performed endoscopic urethrotomy successfully for the treatment of urethral strictures caused by inflammatory polyp and gonococcal urethritis in a 6-year-old and 12-year-old boy, respectively, and urethral complete interruption after pelvis injury in a 14-year-old boy. We recommend a small caliber endoscope for pediatric urethral strictures and obstructions for endoscopic urethrotomy, which is a safe and effective procedure.
