Vasovasostomy(Vasectomy Reversal) is a micro surgical procedure performed that treats obstruction of the vas deferens which is most commonly caused by a previous vasectomy. The use of a modern surgical dissecting microscope allows and affords a very precise anastomosis or tubular reconnection to be performed. The micro surgical vasovasostomy is the procedure of choice or "gold standard" for the vasectomy reversal. Microscopic vasoepididyonosty is performed when the tissue quality of the vas deferens is such that a primary union of the vas deferens segments will yield a low chance of success. During this procedure the vas deferens is sutured directly to epididymal tubules.
