Ten patients with patent urethral duplication are presented. Nine patients had two independent patient channels originating from the bladder or the posterior urethra. Both voiding cystourethro and retrograde urethrography are necessary to completely evaluate this anomaly. In each instance the ventral channel, regardless of the position of its meatus, proved to be the more functional urethra. In those patients whose dorsal channel was in an epispadiac position, the symphysis pubis was abnormally wide. A functionally and anatomically accurate classification is proposed, and the embryology of these anomalies is discussed.
本文报告了10例尿道重复畸形患者。9例患者有两个独立的源于膀胱或后尿道的排尿通道。排尿性膀胱尿道造影和逆行尿道造影对于全面评估这种异常情况都是必要的。在每种情况下，腹侧通道，无论其尿道口位置如何，都被证明是功能更完善的尿道。在那些背侧通道处于尿道上裂位置的患者中，耻骨联合异常增宽。本文提出了一种功能和解剖学上准确的分类方法，并讨论了这些异常情况的胚胎学。
