目的 探讨女性宫内节育器使用年限及类型与生殖道感染的关系,以降低生殖道感染率。方法 2013年1月—2015年1月于我院门诊检查使用宫内节育器360名女性的临床资料进行回顾性分析,研究节育器使用年限、类型、患者年龄、孕次、是否绝经与生殖道感染的关系。结果 带尾丝组患者的生殖道感染率比不带尾丝组高(P<0.05),无尾丝组生殖道感染率与置器年限无关,差异无统计学意义(P>0.05),带尾丝组生殖道感染率与置器年限有关,差异有统计学意义(P<0.05)。生殖道感染率与与女性年龄及妊娠次数无关,与是否绝经有关,未绝经女性的生殖道感染率较高(P<0.05)。结论 带尾丝的宫内节育器的使用可使生殖道感染率增加,使用年限越长,生殖道感染的发生率越高。

Objective To investigate the associations between different time and types of intrauterine device with female reproductive tract infection in order to provide evidence for reducing infection rate. Methods 360 females using intrauterine device were continually recruited during Jan 2013-Jan 2015 in our hospital, and their clinical data was also collected in the same period. The associations between reproductive track infection and clinical characteristics including service time, types, age, gravidity and menopause status were further analyzed. Results We found that the female using intrauterine device with tail wire, as well as with non-menopause had higher infection risk than those did not have(P<0.05). In addition, service time of intrauterine device was significantly associated with infection risk in those patients using intrauterine device with tail wire. However, there was no any remarkable relevance for age and gravidity with risk of reproductive track infection. Conclusion The use of intrauterine device with tail wire, as well as longer service time, could cause the increased risk of reproductive track infection for females.
