To evaluate the efficacy of sutureless vasovasostomy using vascular closure staples, 20 male Sprague-Dawley rats were used for the study. In each rat, a sutureless vasovasostomy using vascular closure staples was performed on a randomly selected side, and a conventional end-to-end microsutured anastomosis was performed on the opposite side. Operation time was significantly shorter for sutureless vasovasostomy using vascular staples (p <. 001). Four weeks after the surgery, however, patency rate and granuloma formation were not different for conventional end-to-end vasovasostomy vs. sutureless vasovasostomy. These findings suggest that sutureless vasovasostomy is simple to perform and requires fewer special technical skills. This procedure may provide an alternative to the conventional vasovasostomy.
