The use of the Mitrofanoff principle in achieving clean intermittent catheterisation and urinary continence in children.

The Mitrofanoff principle has been used to achieve clean intermittent catheterisation (CIC) and urinary continence in 28 children. The mean age at operation was 10.1 years (range, 1 to 19 years). A catheterisable conduit was created using the appendix (19), ureter (8), or vas deferens (1). CIC was commenced 10 to 28 days postoperatively (median, 15 days). After a mean follow-up of 13 months (range, 2 to 45 months), 24 children (86%) have achieved successful CIC and urinary continence. Use of the Mitrofanoff principle is a valuable adjunct to the treatment of urinary incontinence in children and may allow successful CIC in patients who are unable to catheterise urethrally.
