RESUMO
Objective To evaluate the use of Mitrofanoff principle in the field of pediatric urology. Methods From May. 1997 to Dec.1999,the Mirtofanoff principle has been used in 7 children to achieve CIC and urinary continence.The mean age of the patients at operation was 8 years (range 3～14 years).A catheterisable conduit was created using the appendix.Either the cecum,ascending colon or plus the terminal ileum were used instead of the bladder or for augmentation of the bladder after detubularization.7 children consisted of an 8 years old boy has lost his bladder,right ureter and bilateral testis due to traffic accident, 4 children with congenital complete urinary incontinence (urogenital sinus abnormality 1,extrophy of bladder after failed reconstruction 1 and shortened urethra 2),and neurogenic bladder 2. Results Immediate success has been achieved in 5 children (70%),who were completely continent and practiced successful CIC via the Mitrofanoff stoma. Conclusions Use of the Mitrofanoff principle is a valuable procedure for urinary diversion in childhood.
