Applications of the KTP laser in the treatment of posterior urethral valves, ureteroceles, and urethral strictures in the pediatric patient.

Purpose: We describes our experience using the potassium titanyl phosphate (KTP)-532 laser in treating posterior urethral valves, ureteroceles, and urethral strictures in the pediatric patient.

Methods: A retrospective chart review was performed from 1987 to 1997 on a total of 33 pediatric patients who underwent retrograde endoscopic treatment for posterior urethral valves (PUV), ureteroceles (UC), and urethral strictures using a KTP-532 laser.

Results: Overall, our success rate was excellent in the treatment of valves and ureteroceles.
