Vasectomy can be performed by means of various techniques, although each va
sectomy technique requires isolation and division of the vas and operative
management of the vasal ends. Removal of at least 15 mm of vas is recommend
ed, although division of the vas without removal of a segment is effective
when this technique is combined with other techniques for handling the vasa
l ends, such as thermal luminal fulguration and proximal fascial interposit
ion. Ligation of the ends without the aid of surgical clips may result in n
ecrosis and sloughing of the ends, which may cause early failure. Leaving t
he testicular end of the vas open has been shown to be effective and to res
ult in a lower incidence of epididymal congestion and sperm granuloma. The
no-scalpel technique offers shorter operating time, less pain and swelling,
and faster recovery.
