The Use of Stomach in Pediatric Urinary Reconstruction

Abstract

We report on 30 consecutive patients (mean age 9 years) who underwent gastrocystoplasty (21) or received a continent urinary reservoir with stomach (9). A successful outcome, defined as complete urinary continence for intervals greater than 3 hours, preservation or improvement of the upper tracts and renal function, and normal electrolyte and acid base balance, was achieved in 90% of the patients who received continent urinary reservoir and 72% of those who underwent gastrocystoplasty. Urodynamic data were obtained in 17 patients in the gastrocystoplasty group and 7 in the continent urinary reservoir group at a mean of 6 months postoperatively. Metabolic alkalosis associated with hypergastrinemia occurred in 2 children. Partial excision of the gastric segment was necessary in 1 patient refractory to medical treatment.
