自１９６０年全国推广宫内节育器（ＩＵＤ）至今己有千万妇女进入绝经期，绝经后ＩＵＤ应予取出，但因种种因素尚有相当比例绝经后妇女并未取出ＩＵＤ。作为异物的ＩＵＤ长期不取是否安全？尚未报道。本研究调查了普查对象中绝经后妇女２６５８例，其中未取ＩＵＤ者３０２例（ＩＵＤ组）和无ＩＵＤ妇女２５４例进行比较。通过病史询问和妇科检查结果提示：１．绝经后未取ＩＵＤ者平均绝经年龄为４９．７３岁，明显高于对照组（４８．９９）；子宫明显萎缩者与对照组相似；对健康情况无明显影响；患病史中ＩＵＤ组明显低于对照组。２．通过２７６例宫腔分泌物直接涂片检查，白细胞和细菌计数与对照组相似。３．１２８例同时取出ＩＵＤ，取器困难率于绝经＜２年者为５％，≥２年者１８％～３５％。根据本研究结果，绝经后未取ＩＵＤ者未见明显的危害性，但建议有条件取器者应在１年内取器，如绝经２年以上遇有取器困难而临床又无症状，不宜强行取器，以免造成严重创伤，可严密随访。 Since IUD promotion in 1960, there have been tens of millions of women entering menopause and post-menopausal IUDs should be taken out. However, a considerable proportion of these factors do not remove IUDs from postmenopausal women. As a foreign body IUD long-term take is not safe? Not yet reported.

The average age of menopause who did not take IUD after menopause was 49.73 years old, which was significantly higher than that of the control group (48.99). The atrophy of the uterus was similar to that of the control group, but had no significant effect on the health status. In the control group. 2. Through 276 cases of uterine secretions direct smear examination, white blood cell and bacterial counts similar to the control group. 3.128 cases of simultaneous removal of IUD, difficulty in taking the device in menopause <2 years was 5%, ≥ 2 years, 18% to 35%. According to the results of this study, no post-menopausal IUD were no obvious hazard, but it is recommended that conditions should be removed within 1 year, such as menopause more than 2 years in case of difficulties with the device asymptomatic clinical and should not be forcibly Take the device, so as to avoid serious trauma, can be closely followed.
