Duplication of the vas deferens is a very rare congenital anomaly in which two vasa deferentia coexist within the spermatic cord. Duplication of the vas deferens can be found during herniorrhaphy, vasectomy, and varicocelectomy performed on the spermatic cord or around the spermatic cord. However, it is estimated that the incidence of duplication of the vas deferens is under-reported and under-recognized. Unless anomalies of the vas deferens such as duplication of the vas deferens are recognized by surgeons, it will be difficult to reduce vas deferens injuries and achieve a satisfactory surgical outcome. In addition, care should be taken in cases of duplication of the vas deferens because it can be complicated by non-testicular genitourinary anomalies. We report a case of duplication of the vas deferens discovered during routine varicocelectomy.
输精管重复是一种非常罕见的先天性异常，在这种情况下，两条输精管存在于精索内。输精管重复可在精索或精索周围的疝修补术、输精管结扎术和精索静脉曲张手术中发现。然而，据估计，输精管重复的发生率被低估和认识不足。除非外科医生认识到输精管的异常，如输精管重复，否则很难减少输精管损伤并获得满意的手术效果。此外，在输精管重复的情况下应谨慎处理，因为它可能与非睾丸泌尿生殖系统异常有关。我们报告了一例在常规精索静脉曲张手术中发现的输精管重复病例。
