Basing themselves on fourteen personal cases, the authors propose a distinction between two types of congenital lesions obstructing the anterior urethra--valves and diverticula. The main difference between the two resides in the fact that, while diverticula develop outside the corpus spongiosum, the prevalvular distension, in the case of valves, is covered by it. Valves must be treated by endoscopic resection, and this procedure gave good results in all three cases in which it was followed. A surgical approach to a valve through the walls of the urethra involves a risk of late severe stenosis. Diverticula have been successfully managed surgically in a single operation by ablation followed by reconstruction of the urethra. Attempts to treat them by endoscopic resection of the anterior border of the diverticulum were unsuccessful. Three diverticula were non-obstructive, and a cowperian origin was probable in two cases.
基于14例个人病例，作者提出了两种阻塞前尿道的先天性病变——瓣膜和憩室之间的区别。两者的主要区别在于，憩室在海绵体之外形成，而瓣膜导致的瓣膜前扩张则被海绵体覆盖。瓣膜必须通过内镜切除术进行治疗，该手术在所进行的三例病例中均取得了良好效果。经尿道壁对瓣膜进行手术会有后期严重狭窄的风险。憩室通过切除后重建尿道在一次手术中成功得到处理。试图通过内镜切除憩室前缘来治疗憩室未获成功。三个憩室无阻塞，其中两例可能起源于尿道球腺。
