Duplicated vas deferens, an incidental finding during inguinoscrotal hernia repair. A case report.

Isolated duplication of the vas deferens is a rare male reproductive system congenital anomaly with an estimated worldwide prevalence of 0.05%. It is often recognized as an incidental finding during surgeries including vasectomy, inguinal hernia repair, orchidopexy, or varicocelectomy. The number of case reports on this condition are very limited suggesting it is either rarer than the reported estimates or highly underrecognized and underreported. Failure to recognize an iatrogenic injury to the vas deferens can lead to postoperative complications including chronic pain, spermatic granuloma, and failure of sterilization after vasectomy. Considering the high number of hernia repair procedures performed worldwide, surgeons should be aware of this anomaly to reduce the risk of complications. Herein, we present a 69-year-old man with an isolated duplicated vas deferens which was discovered during robot-assisted laparoscopic unilateral inguinoscrotal hernia repair.
