Microdot Technique Vasovasostomy

The Microdot method for performing vasectomy reversal is a variation of the standard multi-layer reverse vasectomy procedure. Similar 10-0 Nylon and 9-0 Nylon sutures to microsurgical vasovasostomy are used to re-approximate both layers of the vas deferens.

The microdot technique allows for easy placement of the mucosal 10-0 Nylon sutures. The microdots guarantee even placement of the mucosal sutures. Re-alignment of the vas deferens is performed during the reverse vasectomy procedure to ensure patency of the lumen of the vas deferens and to prevent long-term scarring of the vasectomy reversal procedure

Once the inner luminal sutures are tied, the knots are cut precisely. Because of the very small size of the vas deferens lumen, any redundant suture material can obstruct the flow of sperm along the vas deferens. Likewise, sperm leakage outside of the lumen can cause obstruction of the vas deferens. A water tight closure of the vas deferens mucosa prevents sperm from leaking out of the vas deferens after the procedure.

The outer serosal sutures are equally important in the reverse vasectomy procedure. These sutures relieve tension off of the finer inner luminal sutures and prevent the ends of the vas deferens from separating after the reverse vasectomy procedure. Liberal placement of these outer serosal micro-sutures needs to be done under a microscope as well to ensure that the ends of the vas deferens are precisely approximated.
