Urethral lengthening and reimplantation for neurogenic incontinence in children.

We describe our experience with a urethral lengthening-reimplantation operation for the correction of incontinence in 13 myelomeningocele children, 11 of whom had failed to achieve continence on a program of intermittent clean catheterization. The procedure involves lengthening the urethra by formation of a bladder tube, which is reimplanted back into the bladder through a submucosal tunnel. This procedure allows a catheter to be passed but prevents urine from leaking. All of the operated cases are included. All of the children are out of diapers and socially dry. Followup ranged from 8 to 36 months and the problems encountered are described.
