All vasectomy reversals are performed using a two-layer technique, using extremely delicate monofilament nylon microsutures (9-0 and 10-0). The “microdot” technique places small ink dots around the inner opening, and was developed to help inexperienced surgeons place the sutures evenly and accurately. Although some experienced microsurgeons use this technique, in Dr Finnerty’s experience the marking dots are unnecessary, and may in some instances result in an inappropriate number of sutures placed, depending on the individual patient anatomy.
Epididymal repair is also performed in two layers, using a variation of the “intussusception technique” on epididymal the tubule. This technique was developed by Dr. Finnerty to improve the precision and success rate of this difficult and delicate repair.by
