Sutureless vasectomy, an improved technique: 1300 cases performed without failure.

Thirteen hundred bilateral, partial vasectomies have been performed for sterilization, without a failure. The procedure utilizes (1) a small, single incision; (2) no sutures; (3) cautery of each vas deferens lumen with a hand-held, battery-operated, disposable, hot-wire cautery; and (4) sealing of the proximal vas deferens in its sheath with a single tantalum clip. No spermatic granulomas were noted using this technique.
