Surgical intervention in dilated bilharzial ureters

Surgery has often been performed for presumed obstruction in dilated bilharzial ureters but with unrewarding results. In this report 55 non-refluxing dilated bilharzial ureters were studied. Perfusion pressure flow studies and diuresis renography with washout technique were used to diagnose the presence or absence of obstruction. Surgery was performed only when obstruction was proven by PPFS and diuresis renography; thus patients were spared an operation when the obstruction could not be confirmed. Antegrade ureteropyelographic findings, evaluation of peristalsis and transport of urine were the basis for the selection of operation performed. The various surgical procedures are discussed.
