Abstract: Objective：To evaluate the effect of cervical conization on the clinical outcomes of subsequent pregnancy. Methods：Thirty-nine patients who had pregnancy desire with cervical cone cut were retrospective analysed from January 2009 to May 2013. The pregnancy outcomes with cold knife conization（CKC） and loop electrosurgical excision procedure（LEEP） were analyzed. Results：Among all the patients, there were one case of ectopic pregnancy and two cases of embryo damage. In 36 delivery cases, there were three premature delivery (8.3%), three premature rupture of membrane (8.3%), twenty-five cesarean section (72.2%) and seven vaginal dilivery. In those 33 full-term delivery cases, there were 14 cases (38.8%) who underwent the hospitalized tocolysis treatment in their different gestational period. Conclusions：There is not significant effect of cervical conization on the clinical outcomes of subsequent pregnancy. However, the rates of cesarean section and the hospitalized tocolysis treatment were increased in those patients who underwent the cervical conization.
