{Abstract}: Duplication of vas deferens is a very rare anomaly which two vasa deferentia are found in the spermatic cord. It can be recognised during autopsy or cadaveric dissection and also several surgical procedures which require spermatic cord dissection including inguinal hernia repair, orchiopexy, vasectomy, varicocelectomy, vasectomy reversal and radical prostatectomy. Recognition of the duplicated vas deferens is important to avoid surgical complications such as an unsuccessful vasectomy or transection of the vas. It was reported in only three cadavers and 31 patients since 1959. In this study, we describe a new case of duplicated vas deferens found incidentally during routine inguinal hernia repair in a 66-year-old patient. We also review all previously reported cases in the literature to draw attention to this rare but important anomaly.
