Ileocecal bladder augmentation in myelodysplasia.

We discuss 14 children and adolescents with myelodysplasia who underwent bladder augmentation with the ileocecal segment. The bowel was not detubularized nor was the ileocecal valve intussuscepted. Urodynamic evaluation was performed before and after the procedure in 13 patients with a followup of 1 to 8 years. Postoperative capacity and compliance were normal but cecal contractions occurred in 8 patients despite adequate doses of anticholinergics. Reflux was demonstrated at capacity with a cecal contraction in 4 patients but upper tract dilatation and infection were not clinical problems. Three patients required reoperation for complications owing to ureteroileal stenosis and/or urinary tract calculi. Although the clinical results were satisfactory, detubularized segments of bowel with intussuscepted afferent loop valves to prevent reflux may resolve these problems in the future.
