Abstract： Objective To investigate the correlation of different types and time limit of intrauterine device with the incidence of infection of female genital tract.Methods The clinical data of 1350 patients under intrauterine device removal surgery from Jan.2013 to Jun.2014 in Shengjing Hospital of China Medical University was analyzed retrospectively.The correlation of different types and time limit of intrauterine device with the incidence of infection of female genital tract was studied.It was investigated whether the infection of female genital tract was related to age,gravidity or menopause.Results The incidence of infection of female genital tract in patients with intrauterine device which had tail fiber and more than 10 years was 33.9%, and in less than 10 years it was 14.3%;the difference was significant (P＜0.05).The incidence of infection of female genital tract in patients with intrauterine device which had no tail fiber and more than 10 years was 20.7%,and in less than 10 years it was 16.9%;the difference was not significant (P＞0.05).The high incidence of infection of female genital tract in patients with intrauterine device which had tail fiber was not related to age, gravidity and menopause.The incidence of infection of female genital tract in older patients was 29.4%,lower than youngers.The incidence of infection of female genital tract in the patients with less gravidities was 26.5%,lower than those with multiple gravidities.The incidence of infection of female genital tract in the patients in menopause was 30.7%,lower than the patients in non-menopause,but the difference was not significant (P＞0.05).Conclusion The longer time of the patients with intrauterine device which has tail fiber,the higher incidence of infection of female genital tract.

摘要：

目的 探讨宫内节育器的类型及置器年限与女性生殖道感染的关系。方法 回顾性分析中国医科大学附属盛京医院计划生育门诊于2013年1月至2014年6月行宫内节育器取出术的1350例患者的临床资料，研究宫内节育器的类型及置器年限与女性生殖道感染的相关性，并探讨女性生殖道感染的发生是否与年龄、孕产次及绝经与否有关。结果 带尾丝型宫内节育器置器10年及10年以上的女性生殖道感染的发生率为33.9%，置器10年以下的女性生殖道感染的发生率为14.3%，两者比较差异有统计学意义（P<0.05)。无尾丝型宫内节育器置器10年及10年以上的女性生殖道感染的发生率为20.7%，置器10年以下的女性生殖道感染的发生率为16.9%，两者比较差异无统计学意义（P>0.05)。带尾丝型宫内节育器因置器年限长而导致的女性生殖道感染的高发率与年龄、孕产次及绝经与否无明显关系。年龄较大者女性生殖道感染的发生率略低，为29.4%；妊娠次数少者女性生殖道感染的发生率略低，为26.5%；绝经者女性生殖道感染的发生率略低，为30.7%，但各组间的差异无统计学意义（P>0.05)。结论 带尾丝型宫内节育器置器年限过长，可导致女性生殖道感染的发生率升高。
