The abdominal neourethra in children: technique and long-term results.

The abdominal neourethra is a continent bladder tube that is applicable to selected children with anatomical urinary incontinence or urinary retention and a nonnavigable urethra. A 5 to 8-year followup is presented in 6 children in whom the abdominal neourethra afforded normal micturition through it or permitted intermittent catheterization. All children were dry between bladder emptyings as a result of a continence mechanism that combined a long elastic tube and a cephalad neourethral abdominal opening with a rectus striated muscle sphincter.
