Anterior urethral valves resulting from congenital urethral diverticula.

Five cases of anterior urethral diverticula with resulting anterior urethral valves are reported. All children presented with a poor stream. Diagnosis was accomplished by voiding cystourethrography, and treatment was by open resection of the diverticulum in four neonates and endoscopic excision of the valve in a four-year-old boy.
