Modifications of and extended indications for the Pippi Salle procedure.

Total urinary incontinence is a difficult problem faced by the urologist. Several techniques to increase ureteral resistance have been described. The majority of them rely on intermittent catheterization for bladder emptying, especially in neurogenic incontinence. We have developed a new procedure in which a bladder flap is used to create a neourethra. This urethral extension acts as a flap valve to provide continence. Bladder emptying is accomplished by clean intermittent catheterization. Urethral lengthening with an anterior bladder-wall flap was performed in 18 patients aged a mean of 8.9 years who had neurogenic incontinence (14) or exstrophy (4). Patients with previous bladder interventions received a lateralized anterior flap. Bladder augmentation was performed in 14 of the 18 patients [detubularized ileum (11), detubularized colon (3)]. The average follow-up period is currently 29.3 months. Continence was achieved in 13 of the 18 patients (72%). Complications included urethrovesical fistulae, which developed in two patients. Two patients could not perform catheterization due to pain but had no obstruction to passage of catheter (exstrophy). Ureteral lengthening with an anterior bladder-wall flap is a useful alternative for the surgical treatment of urinary incontinence. This technique achieves a good continence rate and presents few problems with catheterization.
