Use of exteriorized stents in vasovasostomy

Ten patients, three to fifteen years postvasectomy, underwent vasovasostomy. Using 2-0 nylon, stents were brought to the scrotal surface. Vas anastomosis was accomplished with a single transmural layer of 6-0 or 7-0 proline or chromic sutures under loupe magnification. Stents were removed in seven to ten days. After two years, a pregnancy rate of 70% was achieved, comparing favorably with other more difficult operative techniques.
