Talk to Urologist on Varicocele

I am having grade 3 varicocele on left side and grade 1 on right side. one of the dilated vessels in left side measuring about 3.2 mm in short axis showing reflux during the Valsalva maneuver. I want to have a microsurgery but I don’t know who is the best, I don’t want to take risk by embolization because there’s a chance of recurrence, so plz suggest me the best urologist in Pakistan. That has all the equipments for microscopic varicocele surgery.
