目的：对固定式带铜宫内节育器（ＦｃｕＩＵＤ）的临床避孕效果及其副作用和可接受性进行探讨。方法：通过离体子宫、动物实验、月经血测量及细菌培养以证实其效果的可靠性、安全性和可行性。结果：自１９９３年４月至１９９４年１２月共放置ＦｃｕＩＵＤ２４３例，总随访率９９．６２％。最短放置３５个妇女月，最长放置５５个妇女月。累计带器妊娠率２．４８％；脱落率与因症取出率各为３．０５％，１～４年续用率分别为９３．５０％、９２．１１％、９１．２５％及９０．８７％。结论：ＦｃｕＩＵＤ是一种脱落率低、副作用小、续用率高、安全性大的新型ＩＵＤ，对有频繁脱器史者更为适宜。
Objective: To investigate the clinical contraceptive effect, side effects and acceptability of FcuIUD. Methods: To verify the reliability, safety and feasibility of the effect by uterus, animal experiments, menstrual blood measurement and bacterial culture. Results: From April 1993 to December 1994, a total of 243 FcuIUD cases were placed with a total follow-up rate of 99.62%. The shortest 35 women’s months, the longest 55 women’s month. The accumulative pregnancy rate was 2.48%. The rate of exfoliation and the rate of excretion were 3. 05% respectively. The renewal rates of 1 ~ 4 years were 93.50%, 92.11%, 91.25% and 90% respectively. 87%. Conclusion: FcuIUD is a new type of IUD with low shedding rate, small side effects, high continuous use rate and high safety. It is more suitable for patients with frequent abortion.
