The rare duplications of the male urethra--only 210 cases are described till now--are found as many different variations. Only few of these malformations are symptomatic. The embryology is not always clear. Several classifications have been proposed, often too complicated or incomplete. We think, that our classification avoids these disadvantages. Each duplication is systematically classified in a morphological way according to the type of orifice (epispadiac, normotopic on the glans, hypospadiac, perineo-anal), without urinary transport (distal abortive types) or with urinary transport. The latter type can be complete (if a channel exists between bladder and an external meatus) or incomplete (if a channel exists between bladder and any point of the normal urethra or between the normal urethra and any accessory meatus). Four cases are reported and therapeutical aspects are discussed.
男性尿道重复畸形较为罕见——迄今仅报道过210例——存在多种不同的变异形式。这些畸形中只有少数有症状。其胚胎学情况并不总是很清楚。已提出了几种分类方法，但往往过于复杂或不完整。我们认为，我们的分类避免了这些缺点。每种重复畸形都根据尿道口类型（阴茎头型尿道上裂、阴茎头正常位、尿道下裂、会阴肛门型）进行系统的形态学分类，分为无尿流通道（远端闭锁型）或有尿流通道。后一种类型可以是完全性的（如果膀胱与外尿道口之间存在通道）或不完全性的（如果膀胱与正常尿道的任何一点之间存在通道，或正常尿道与任何副尿道口之间存在通道）。本文报告了4例病例并讨论了治疗方面的问题。
