The role of dilatation in bilharzial ureters.

Endoscopic dilatation of bilharzial ureteric strictures was carried out in 35 men and four women. The procedure had to be repeated in 10 patients after 2 months and three patients have required regular dilatation every 4 months for the last 2 years. The selection of patients is important since they should have neither an active lesion nor a stenotic calcific one.
