Sutureless vasovasostomy using new vascular closure staples in rats

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