RESUMEN
Of the 37 patients with exstrophy of the bladder in whom ureterosigmoidostomy was selected as the mainstay of treatment 4 died of causes related to the procedure. Faulty judgment and poor followup accounted for these deaths, which might well be preventable today. In 18 survivors, or approximately half of the entire series, the operation has held up well for many years, with no further surgical procedure being required for complications. In 12 patients, or approximately a third of the group, remedial operations for complications attributable to the ureterosigmoidostomy have been required but it was elected to retain this form of diversion. The long-term end result in these patients also remains acceptable. Combining these 2 groups 30 of 37 patients with ureterosigmoidostomy may be considered to have been eventually successful. However, in 7 of 37 patients the method was a frank failure, in that 4 patients died and 3 required substitution of another form of diversion. While all forms of treatment of exstrophy of the bladder leave much to be desired, results obtainable in today's setting lead us to recommend ureterosigmoidostomy as first choice in the management of this disorder. This recommendation is accompanied by the admonition that systematic followup is imperative so that if things do go badly from the clinical, laboratory or urographic viewpoint corrective measures can be done before renal deterioration occurs. The measures required may range from simple correction of electrolytes to conversion to an ileal loop.
