Duplication of vas deferens is a rare congenital anomaly. All previously reported cases of this rare anomaly were identified during procedures such as orchiepexy, inguinal hernia repair, vasectomy, varicocoelectomy, and radical prostatectomy. Here, we report a case of unilateral duplicated vas deferens noted in an adult cadaver during regular dissection for medical students. The right spermatic cord contained 2 separate and completely developed cord-like structures. Both cords communicated separately with the tail of the epididymis. When traced cranially, both traversed the inguinal canal as content of the spermatic cord and finally fused at the level of the deep inguinal ring. No other variations were found in the testis or epididymis, and no variations were seen in the left spermatic cord. In addition, no associated renal abnormalities were noted.
输精管重复是一种罕见的先天性异常。此前报道的所有这种罕见异常病例都是在诸如睾丸固定术、腹股沟疝修补术、输精管切除术、精索静脉曲张切除术和前列腺根治术等手术过程中发现的。在此，我们报告一例在为医学生进行常规解剖时，在一名成年尸体中发现的单侧输精管重复病例。右侧精索包含2个独立且完全发育的索状结构。两根索状结构分别与附睾尾部相连。向上追踪时，两根索状结构均作为精索内容物穿过腹股沟管，最终在腹股沟深环水平融合。在睾丸或附睾中未发现其他变异，左侧精索也未见变异。此外，未发现相关的肾脏异常。
