title: Anterior urethral valve in an adolescent with nocturnal enuresis.
abstract: The anterior urethral valve (AUV) is a rare congenital urethral anomaly that can lead to variable urinary tract symptoms. We report on a 13-year-old boy with AUV who was referred from a primary care physician for nocturnal enuresis. AUV was disclosed by videourodynamic study and confirmed by simultaneous retrograde cystourethroscopy and antegrade urethroscopy. The AUV was ablated by neodymium:yttrium-aluminum-garnet contact laser at the 5-o'clock and 7-o'clock directions. A postoperative videourodynamic study depicted a patent urethra, a good maximal flow rate, and improved bladder capacity. His nocturnal enuresis had completely subsided at a follow-up period of longer than 24 months.
