A Case of Duplicated Vas Deferens Found Incidentally during Varicocelectomy
A 22-year-old male patient presented with a worm bag-like scrotal mass accompanied by scrotal pain. His past medical history and family history was insignificant. On physical examination, he was diagnosed with left varicocele (grade 3), and there were no other abnormal findings in the external genitalia. A semen analysis revealed asthenospermia and it was decided to perform varicocelectomy. Using an inguinal approach, varicocelectomy was performed through a small skin incision over the inguinal canal under spinal anesthesia. Upon isolating the left spermatic cord, two vasa deferentia were identified in the spermatic cord (). On Doppler, both structures showed no signal, whereas an arterial signal was noted in the vascular structure lateral to the duplicated vas deferens. They were separated from the level of the internal inguinal ring to the level of the epididymal tail (). After duplication of the vas deferens was confirmed, the enlarged veins were ligated and varicocelectomy was performed. The other side of the scrotum was also carefully examined, but it was confirmed that only one vas deferens was present on that side. The patient's postoperative course was uneventful. The postoperative abdominal-pelvic computed tomography (CT) scan did not identify any genitourinary malformations such as ipsilateral renal agenesis. At the 6-month follow-up, there were no signs of varicocele and the external genitalia were found to be otherwise normal.
