The Mitrofanoff procedure: 20 years later
Abstract
PURPOSE: We review our initial cases of continent cystostomy to assess long-term functional results and complications after a minimum of 15 years of followup.
MATERIALS AND METHODS: Between 1976 and 1984, 23 continent cystostomies were performed on 15 boys and 8 girls with neuropathic bladders. Mean patient age at surgery was 8 years and 4 months (range 3 to 16) and mean followup was 20 years (range 15 to 23). The neurological lesions were due to 21 myelomeningocele (2 associated with an imperforated anus in 21 cases), spinal neuroblastoma in 1 and complex genitourinary malformation associated with an imperforated anus in 1. Closure of the bladder neck was performed in 21 cases (16 during the same procedure, 5 secondarily) and 2 did not undergo this procedure. The appendix was used as the catheterizable conduit in 20 cases, 1 ureter in 2 and a bladder tube in 1. Bladder augmentation was performed during the same procedure in 2 cases and at a later stage in 8. Five patients presented with unilateral or bilateral secondary vesicoureteral reflux.
RESULTS: One death occurred after conversion to cutaneous diversion due to a postoperative infection leading to a ventriculoperitoneal valve infection. The remaining 22 patients were followed every 6 to 12 months. No metabolic disorder, secondary malignancy or spontaneous bladder perforation was noted. Bilateral upper tract deterioration was found in 10 cases leading to secondary bladder augmentation by enterocystoplasty in 6 and…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 22 participants or records.
