Role of visual internal urethrotomy in pediatric urethral strictures

Single VIU is successful for about one-quarter of pediatric patients with a urethral stricture. With repeated VIUs or dilatations 71% of the patients can achieve success. In strictures less than 2 cm, up to three VIUs can be attempted, but longer strictures need open correction if the patient does not wish to follow the home dilatation program.
