The time for IUD removal is 3 to 7 days after menstruation is clean; women in menopausal transition should remove the IUD within one year after menopause; IUD combined with early pregnancy should be removed at the same time as abortion; ectopic pregnancy with device should be removed before discharge from the hospital; irregular uterine bleeding can be removed at any time, and diagnostic scraping is needed to remove the IUD at the same time, to exclude endometrial lesions. The IUD can be removed during 3-7 days after menstruation, when the endometrium is the thinnest and the removal of the IUD is not likely to cause bleeding, so women of childbearing age can have the IUD removed during this time. Peri-menopausal women who have experienced amenorrhea for six months can have the IUD removed. Pregnancy with an IUD can be removed at the same time as an abortion; if the IUD is found to be ectopic, it can be removed after surgery and before discharge from the hospital. If there is abnormal bleeding from the uterus, the IUD can be removed at any time, but at the same time, diagnostic scraping should be done, and the scraped out tissues should be sent for pathological tests to exclude endometrial lesions.
