Is Endoscopic Transurethral Incision Really Effective for Boys with Refractory Daytime Incontinence?

PURPOSE: To determine the clinical efficacy of endoscopic transurethral incision (TUI) for boys with refractory daytime incontinence due to a posterior urethral valve with or without nocturnal enuresis. PATIENTS AND METHODS: A total of 20 boys with daytime incontinence were assessed. Twelve boys underwent TUI (TUI+ group) and eight boys continued receiving oral drugs (TUI- group). The primary endpoint was the cure rate associated with TUI or NE in both groups. RESULTS: Only two boys achieved daytime continence 6 months after TUI, but no boys were cured of nocturnal enuresis 6 months after TUI. The median time to daytime continence was significantly longer in the TUI+ than in the TUI- group (52 vs 27 months, respectively; log rank P = 0.041) and the median time to dry nights was significantly longer in the TUI+ than in the TUI- group (56 vs 36 months, respectively; log rank P = 0.021). CONCLUSION: TUI might be not effective in boys with refractory daytime incontinence.
