对频脱环妇女放置含铜宫形器(UCD Cu200)进行临床效果观察,并以多荷Cu250(ML Cu250)作为对照,随机放置各211例。随访观察24个月,随访率100%。24个月时UCDCu200和MLCu250每百妇女净累积续用率分别为93.35和90.99,经X~2检验两组间有极显著性差异(P<0.01)。24个月时粗累积妊娠率(0.97和3.42)、脱落率(2.46和3.93)、因症取出率(2.41和1.46),两组均无显著性差异(P>0.05);副反应均以月经过多和点滴出血较多见,两组间无明显差异(P>0.05),表明频脱环妇女放置UCDCu200符合宫腔形态,适应子宫动态变化,避孕效果满意。
The clinical effects of copper-containing uterus (UCD Cu200) placed on women with frequency de-looping were observed and 211 cases were randomized with Cu250 (ML Cu250) as control. Follow-up observation of 24 months, follow-up rate of 100%. At 24 months, the net cumulative follow-up rates per 100 women for UCDCu200 and MLCu250 were 93.35 and 90.99, respectively. There was a significant difference between the two groups (P <0.01) by X ~ 2 test. At 24 months, the cumulative pregnancy rates (0.97 and 3.42), exfoliation rates (2.46 and 3.93), the rate of removal due to illness (2.41 and 1.46), no significant difference between the two groups (P> 0.05); side effects were menstrual Excessive and spotting bleeding more common, no significant difference between the two groups (P> 0.05), indicating that the frequency of dendritic ring UCDCu200 placed in line with the uterine morphology, dynamic changes to adapt to the uterus, contraceptive effect is satisfactory.
