title: [Endoscopic operation of congenital anterior urethral valve. Application of flexible renoureteroscope for antegrade urethroscopy].
abstract: 4 children with anterior urethral valve were treated by TUR-Valve. Before TUR, valve anatomy could be easily seen by antegrade urethroscopy through cystostomy using a 10.8Fr caliber flexible renoureteroscope and destruction of the valve could be recognized after TUR. Antegrade urethroscopy with a flexible fiberscope was so helpful to TUR-Valve and the findings of voiding cystourethrography and micturition have remarkably improved. This technique is not so difficult to apply and thought to be one of the best methods to recognize valve anatomy and degree of resection. This technique is also applicable to other lower urinary tract lesions in children.
