No-Scalpel Vasectomy

No-Needle, No-Scalpel Vasectomy ... learn more

Vasectomy is considered to be the safest, and most reliable, method of permanent male sterilization. It is believed to be free of known long term side-effects. It is also the most common method of male contraception in the USA where about 500,000 vasectomies are done each year.

Needle-less Vasectomy is an improved approach which has eliminated the traditionally needle injection of local anesthetic. Instead this "numbing" medication is applied using non-invasive newer technology. The area involved is initially desensitized by the application of a topical cream. This effect is then deepened by jet inoculation technology. This allows for a completely painless experience without invasive anesthesia.

No-Scalpel Vasectomy is an improved technique which results in decreased procedure time, less associated discomfort, more rapid recovery and lower complication rates.

In a conventional vasectomy small incisions, with a knife, are made in the skin. These are usually large enough that sutures, or stitches, are required to close the cuts at the end of the procedure. In the no-scalpel method, by using a microsurgical approach and instead of making incisions, a tiny puncture is made into the skin with a special instrument. This opening is so small that no stitches are needed for closure. Instead it will automatically contract and heal with little, or no, scarring.

No-scalpel vasectomy was developed in China in 1974 and then introduced into the USA in 1988. It is now used, in this country, by doctors who have mastered the technique.

The no-needle jet anesthetic technique, originally pioneered in North America, was introduced to the U.S. urological market at the 100th annual meeting of the American Urological Association (AUA) in San Antonio May 21-26, 2005.

Not all urologists are using these newer methods.

The vasectomy is then completed by dividing the vas deferens.

  • The end which leads to the testicle is not "blocked off" or closed. This has been referred to as the "open-ended" technique. This was developed in 1977 and has subsequently been proven to markedly reduce post-vasectomy discomfort, not change the risk of reconnection but instead to improve the success of vasectomy reversal if this is eventually done.
  • The end which leads away from the testicle is then occluded by electrocautery. This technique gently obliterates the ductal lining and allows the treated portion of the channel to permanently scar. This approach gives the highest chance for success and the lowest probability for automatic reconnection.
  • A 1.5 cm section of the duct is also removed. Both ends are then placed in separate, non-connecting, locations. These additional precautions appear to improve even further the success rate of the procedure.

Our focus has been, and continues to be, on continuously improving these minimally invasive approaches. No shaving is required, only small amounts of anesthetic are needed and sedation is not necessary. Patients are able to drive themselves home and to return to full activity within several days time.

Needle-Less No-Scalpel Vasectomy is the ideal approach if permanent male sterilization is desired.
