Coagulation and Fascial Interposition: Minimizing The Risk of Failure
The chance of vasectomy failure is greatly decreased by performing coagulation during division of the vas deferens.
Then using a small hand held, battery powered thermal coagulation device, the vas deferens is opened with thermal dissection.
The tip of the coagulating device is then introduced into the upper (prostatic end) and the inside of the upper vas deferens is lightly coagulated. This technique results in accelerated closure of the upper end and decreases the risk of vasectomy failure.
Once the upper end has been coagulated the vas deferens is dividing with the thermal device at the point of initial entry.
This step creates a division in the vas deferens: upper and lower ends. The upper end is also called the prostatic end. The lower end is also called the testicular end. The two ends will soon be separated so reconnection is more difficult.
Performing light coagulation to the inside of the upper vas deferens minimizes the risk of a reconnection of the two ends.
Additionally separating the two divided ends with facial tissue provides one additional barrier to minimize the risk of reconnection and vasectomy failure.
