Unfortunately, 5% of those diagnosed with a varicocele have recurrence despite surgery. There are normally 3 surgical approaches - including embolization, ligation and laparoscopy.
The reason why there is so much confusion is because there is no clear course of treatment. Repeat surgery or repeat embolization would all be reasonable considerations in your case. I am not aware of data suggesting that one course is better than another in repeat occurances of varicoceles.
If there is no consensus, you may want to inquire about a referral to an academic medical center where presumably they would have more experience with varicoceles.
Followup with your personal physician is essential.
