宫内节育器与宫颈糜烂发病率的临床研究

The Clinical Research of IUD Relationship With the Incidence of Cervical Erosion

目的：探讨带尾丝宫内节育器（IUD）与宫颈糜烂发病率的关系。方法选取2006年1月～2009年3月在黄州区计生服务站自愿要求以IUD避孕的已育妇女，共计4080名，按照就诊的顺序编号，奇数号为实验组，偶数号为对照组，在允许放置节育器的情况下，不考虑宫颈原有糜烂情况，实验组放置有尾丝的IUD，对照组放置无尾丝的IUD，所有的女性均在上IUD后第1、3、5年妇检普查时随访，观察宫颈病变的情况。结果除去实验组2040人中终止放置节育器的人数32人，对照组2040人中终止放置节育器的人数43人。放置满5年的已育妇女中，放置有尾丝IUD的妇女2008人与无尾丝的IUD的妇女1997人相比，第1、3、5年宫颈糜烂发病率均有统计学差异（P〈0.05）。结论放置有尾丝的IUD随着放置年限的增加，宫颈糜烂的发病率也增加。

Objective To investigate the relationship between intrauterine device（IUD）and the incidence of cervical erosio.MethodsA total of 4 080 childbearing women contracepted with IUD from January 2006 to March 2009 in the birth control service station of huangzhou district were selected and the patients were divided into experimental group（odd number）and control group（even number）according to the order of treatment. Experimental group placed tail wire IUD,which controls group placed tailess wire IUD. Al of the women were folowed up for first,third and fifth years after placing IUD,and the cervical lesions were observed.ResultsThirty-two people who terminated placing IUD in experimental group,and 43 people who terminated placing IUD in control group were al removed. Incidence of cervical erosion in the first,third and fifth years after placing IUD in experimental group had statistical difference with those of control group（P〈 0.05）.Conclusion The incidence of cervical erosion increases with the increase of the years of placing the tail wire IUD.
