Orthotopic urethral substitution in female patients using the mitrofanoff principle.
OBJECTIVE
We present our experience with orthotopic urethral substitution in female patients using the Mitrofanoff principle.


METHODS
We performed orthotopic urethral substitution using the Mitrofanoff principle in 18 female patients 1 to 29 years old (mean age 10). The conduit was constructed with appendix in 13 cases, tapered ileum in 4 and fallopian tube in 1. The etiology of incontinence included exstrophy in 8 patients, neurogenic bladder in 3, urogenital sinus in 3, and bilateral ectopic ureter, ectopic ureterocele, the prune-belly syndrome and post-cystectomy undiversion in 1 each.


RESULTS
Mean followup was 29 months (range 9 to 72). A total of 16 patients achieved continence following a program of clean intermittent catheterization. There were 2 unsuccessful operations. In 1 case the appendix become ischemic and in 1 a vesicoperineal fistula developed. One patient catheterizes every 2 hours to avoid leakage. Catheterization was temporarily difficult in 5 patients, of whom 2 had an appendiceal and 3 had a tapered ileal conduit. Two patients with an ileal conduit have had chronic difficult catheterization.


CONCLUSIONS
Orthotopic replacement of the urethra using the Mitrofanoff principle is suitable in highly select female patients who need continent diversion or a catheterizable conduit but who will not accept an abdominal stoma. It is particularly suited to patients in whom exstrophy reconstruction has failed.
