Ureteral valves in children

OBJECTIVES: Congenital ureteral valves are a rare cause of ureteral obstruction in children, with only 42 cases having been reported in peer-reviewed literature. Eight additional cases of ureteral valves are herein reported. METHODS: We report on the diagnosis and management of eight children with ureteral obstruction secondary to a ureteral valve. RESULTS: Eight children with congenital ureteral valves were managed by ipsilateral ureteroureterostomy, ureteropyelostomy, or longitudinal ureterotomy with excision of valve leaflets. The obstruction was relieved in all. CONCLUSIONS: Ureteral valves should be included in the differential diagnosis of ureteral obstruction in children. Reconstruction is curative.
