We report the use of the Mitrofanoff principle to achieve urinary cont
inence in 47 patients. A catheterizable channel can be used as the pri
mary continence mechanism, or as an adjunct to ensure complete bladder
emptying if urethral catheterization or voiding is inadequate. Append
ico-vesicostomy was performed in 25 of 47 patients (55%). Satisfactory
continence was achieved in 45 patients (96%). Bladder emptying by cle
an intermittent catheterization was performed in all patients. Early c
omplications included peristomal abscess (1 patient) and small bowel o
bstruction (1). Late complications included difficulty with catheteriz
ation (5 patients), stomal stenosis (9) and persistent incontinence (2
). Our results support use of the appendix as the catheterizable segme
nt of choice. We describe the technique and discuss the management of
complications.
