The authors present a case of ectopic opening of the left ureter into the seminal tract. This was a very young child (14 months). The diagnosis was made on intravenous pyelography on direct signs (opacification of the malformation). There was a wide communication between the latter and the posterior urethra as was shown on retrograde urethrocystography. The urinary tracts on the side of the lesion were very fine, and there was an outline of a very mildly functional kidney. Embryologically it is a case of absence of separation between the ureteral bud and the Wolffian canal.
作者报告了一例左输尿管异位开口于精道的病例。患儿年龄很小（14个月）。通过静脉肾盂造影的直接征象（畸形部位显影）做出诊断。逆行尿道膀胱造影显示，畸形部位与后尿道之间存在广泛交通。病变侧的尿路非常纤细，有一个功能非常轻微的肾脏轮廓。从胚胎学角度来看，这是一例输尿管芽与中肾管未分离的病例。
