Posterior urethral valves have a broad clinical spectrum. In this series of 87 patients, 36 had mild valvular obstruction, the most common clinical variety. Boys with mild valves had a greater frequency of diurnal and nocturnal enuresis, super-imposed infection, and a poor stream. The diagnosis was established by a very strict correlation of the radiological and endoscopic findings. Urodynamic studies, although performed in a limited number of patients, add validity to the diagnosis of mild valves. A classification based on the secondary anatomical changes and functional damage, which divides the valves in mild, moderate, and severe is recommended. Results of the endoscopic fulguration were excellent and without complications; 34 of 36 patients were improved or cured of their disturbing symptoms.
后尿道瓣膜具有广泛的临床谱。在这组87例患者中，36例有轻度瓣膜梗阻，这是最常见的临床类型。患有轻度瓣膜的男孩白天和夜间遗尿、并发感染及尿流不畅的发生率更高。通过将放射学和内镜检查结果进行非常严格的对照来确立诊断。尿动力学研究虽然仅在少数患者中进行，但为轻度瓣膜的诊断增加了可信度。推荐一种基于继发性解剖学改变和功能损害的分类方法，将瓣膜分为轻度、中度和重度。内镜电灼术的结果极佳且无并发症；36例患者中有34例的困扰症状得到改善或治愈。
