本文采用直视下注射针支架法,显微吻合及直视下分瓣外翻三种方法吻合输精管179例.经随访及统计学处理,注射针支架法吻合与显微和直视下分瓣外翻吻合的复通率,再孕率都具有显著差异(P<0.05),而显微吻合与直视下分瓣外翻吻合的复通率、再孕率无差异.并对三种吻合复通机理及失败因素进行了探讨. In this paper, under direct vision injection needle stent method, microscopic anastomosis and strabismus under the valgus valvular three methods consistent vasectomy 179 cases.After follow-up and statistical analysis, injection needle stent anastomosis and microscopic and direct vision under the valve (P <0.05), while there was no difference in the rate of retransplantation between microsurgical anastomosis and ectopic ectopic under direct vision.No difference of re-pregnancy rate was found between the three anastomoses The mechanism and failure factors of Fong Tong were discussed.
