Advantages of rectus fascial slings for urinary incontinence in children with neuropathic bladders.


PURPOSE Many surgical procedures to improve outlet resistance in children with neuropathic bladders are obstructive and increase the detrusor leak point pressure. In contrast, fascial slings are designed to achieve continence by increasing the Valsalva or stress leak point pressure without altering the detrusor leak point pressure. We evaluate the effectiveness of fascial slings in achieving continence in pediatric patients with neuropathic bladder. MATERIALS AND METHODS From October 1994 until February 1999, 10 females and 8 males with neuropathic bladder secondary to myelodysplasia or traumatic spinal cord injury underwent fascial sling procedures. Mean patient age was 14 years (range 8 to 18) and all were incontinent despite aggressive medical management. Urodynamic evaluation was performed preoperatively and postoperatively. Specific urodynamic measurements included detrusor leak point pressure, stress leak point pressure and detrusor compliance. Compliance was only compared in the 12 nonaugmented cases. RESULTS With a mean followup of 21.2 months (range 6 to 57), preoperative and postoperative urodynamics revealed little change in mean detrusor leak point pressure (23.2 versus 23.22 cm. H2O) but a substantial increase in mean stress leak point pressure (41.6 versus 64.5 cm. H2O). Mean compliance was unchanged in the nonaugmented group (22.00 versus 26.78 ml/cm. H2O). Four patients (22.22%) remained wet after surgery, of whom 2 were successfully treated with a repeat sling procedure and 1 with collagen injection for an overall continence rate of 94.44%. CONCLUSIONS Fascial slings can be effectively used in pediatric patients for neuropathic incontinence. Furthermore, stress urinary incontinence is corrected by increasing the Valsalva or stress leak point pressure with preservation of the detrusor leak point pressure. Preservation of detrusor leak point pressure is particularly advantageous because other forms of bladder outlet procedures achieve continence at the expense of increasing detrusor pressures, thus placing the upper tracts at risk for damage.
