[Two cases of congenital urethral stenosis complicated with vesicoureteral reflux]

Secondary vesicoureteral reflux (VUR) is not uncommon, but is rarely accompanied by congenital urethral stenosis in children. We report 2 cases. Case 1 was in a 3-year-old boy who had congenital anterior urethral stenosis accompanied by VUR. Urethroplasty by Johanson's operation was performed and 6 years later VUR disappeared. Case 2 was in a 7-year-old girl, who had congenital peripheral urethral stenosis accompanied by VUR. The urethra was dilated by a balloon-dilator and about 1 year later VUR disappeared.
