Obstructive lesions of the anterior urethra (valves, saccular diverticula) are rare, and can be difficult to diagnose. Three recent cases have led us to review the existing french and english literature and we have found case histories for 81 cases, encountered over a twenty year period. The anatomic interpretation of the lesions is far from being univocal; however many authors clearly distinguish between valves and diverticula, the basic difference residing in the contiguity between the anomaly and the corpus spongiosum. Where the clinical presentation depends on age, the diagnosis depends essentially on the voiding cysto urethrography, which must objectify the whole of the urethra. Generally speaking the treatment for the valves is simple, consisting in endoscopic resection. In the case of diverticula, it is not always necessary or desirable to remove the diverticulum itself; if there is a well-formed distal obstructing lip, removing it may be enough to cure the obstruction.
前尿道梗阻性病变（瓣膜、囊状憩室）较为罕见，且可能难以诊断。最近的三例病例促使我们回顾了现有的法语和英语文献，我们找到了在二十年期间遇到的81例病例的病史。病变的解剖学解释远非单一明确；然而，许多作者明确区分了瓣膜和憩室，基本区别在于异常与海绵体之间的连续性。临床表现取决于年龄，诊断主要依赖于排尿性膀胱尿道造影，该检查必须明确整个尿道的情况。一般来说，瓣膜的治疗很简单，即内镜下切除。对于憩室，并不总是需要或希望切除憩室本身；如果有一个发育良好的远端梗阻性唇，切除它可能足以治愈梗阻。
