【摘要】  目的：对比观察剖宫产后放置吉妮致美爱母记忆母体乐 IUD的临床效果。方法：对648例有剖宫产史的受术者随机分为三组，分别放置GyneFiex MCu记忆合金 MLCu IUD随访1年后观察效果。 结果：放置GyneFiex MCu记忆合金 MLCu IUD 使用1年后脱落率分别为0.44%、1.87%、9.05%;带器妊娠率分别为0.89%、0.94%、2.38%;因症取出率分别为1.78%、2.81%、3.81%;续用率分别为96.7%、94.4%、84.8%。结论：GyneFiex MCu记忆合金MLCu IUD避孕效果均较理想，但MLCuIUD带器妊娠、脱落、月经异常均高于两种新型IUD，两种新型IUD是剖宫产术后放置IUD的首选。

　　含铜活性宫内节育器IUD是长效、简便、经济、安全、可逆及应用最广泛的一种避孕方法，但随着近几年来初产妇平均年龄的提高，高危儿、巨大儿、 珍贵儿的比率呈上升趋势等多方面因素，放宽了剖宫产的指征，初产妇剖宫产的比率不断提高，而剖宫产手术带来的子宫愈合不良，子宫浆膜与腹壁粘连，子宫形态和结构发生改变等，造成剖宫产术后放置宫内节育器后不良反应多，避孕失效率高。本站从2006年6月～2008年7月对剖宫产后自愿要求放置宫内节育器的育龄妇女648例做了详细的观察和随访，对比GyneFiex MCu MLCu IUD使用效果，现报告如下。
