目的观察新型MCu功能性宫内节育器(intrauterine contraceptive device,IUD)的临床效果。方法将自愿放置IUD的育龄妇女分为两组,分别放置MCu IUD270例、MLCu IUD270例,术后第1、3、6、12、24个月随访,分析比较其脱落率、带器妊娠率、因症取出率、续用率、不良反应等。结果 MCu IUD和MLCuIUD24个月累计脱落率分别为0.74%、7.41%;12个月因症取出率分别为1.85%、5.56%;续用率分别为94.44%、84.44%;脱落率、因症取出率、续用率两组比较,差异均有统计学意义(P<0.05)。带器妊娠率MCuIUD和MLCu IUD分别为1.85%、1.48%,两组比较,差异无统计学意义(P>0.05)。结论 MCu IUD是一种脱落率低、因症取出率低、续用率高、不良反应少,避孕效果显著的IUD,值得推广。
Objective To observe the clinical effect of a new MCU functional intrauterine contraceptive device (IUD). Methods The women of childbearing age who were placed in IUD voluntarily were divided into two groups and placed in the MCu IUD270 cases and MLCu IUD270 cases respectively. The follow-up was performed on the 1st, 3rd, 6th, 12th and 24th months after operation. The rate of abortion, Due to disease removal rate, the renewal rate, adverse reactions. Results The cumulative shedding rates of MCu IUD and MLCuIUD in 24 months were 0.74% and 7.41% respectively. The removal rates of the 12 months were 1.85% and 5.56%, respectively. The follow-up rates were 94.44% and 84.44% respectively. Rate, the rate of renewal of the two groups, the difference was statistically significant (P <0.05). The pregnancy rates of MCuIUD and MLCu IUD were 1.85% and 1.48% respectively, there was no significant difference between the two groups (P> 0.05). Conclusion MCu IUD is a kind of IUD with low shedding rate, low withdrawal rate, high follow-up rate, few adverse reactions and significant contraceptive effect. It is worth promoting.
