A rare case of duplicated vas deferens discovered accidentally during varicocelectomy.

Congenital anomalies of the male urogenital tract include a variety of structural abnormalities. These abnormalities could affect either the male external genitalia, internal genitalia or both. Congenital anomalies of the vas deferens are rare and may include unilateral or bilateral (agenesis, atresia, duplication, ectopy or diverticulum) that could be complete or segmental. In addition, they may be isolated anomalies of the vas deferens or may be associated with other congenital anomalies elsewhere especially in the male urogenital tract. Those anomalies may be discovered during genital examination (either clinically or radiologically) or even during inguinal surgeries as in hernia repair, vasectomy, orchiopexy and varicocelectomy. Thus, proper evaluation should be made for the cases of duplicated vas deferens to avoid the accidental injury during the operation and to exclude other associated congenital anomalies. Besides that, the undiagnosed cases may lead to failure of vasectomy procedure. Here, we report a case of duplication of the vas deferens in a 33-year-old male that was accidentally discovered during spermatic cord dissection for varicocelectomy.
