When endometritis occurs, because there is inflammation locally, intrauterine operations cannot be performed, thus the intrauterine device (IUD) cannot be removed. The symptoms of endometritis can include the discharge of purulent secretions from the vagina and tenderness in the lower abdomen, and it can even lead to systemic infection symptoms such as fever. If one wishes to remove the IUD, it is essential to carry out standard anti-inflammatory treatment using antibiotics to treat the inflammation, and the IUD can only be removed after the symptoms have alleviated. The alleviation of symptoms primarily includes the following aspects: First, there is no longer pus discharge from the vagina. Second, there is no longer tenderness or rebound pain in the lower abdomen. Third, there are no symptoms of systemic fever or others. When removing the IUD, comprehensive disinfection should be noted to avoid causing a recurrence of endometritis or spreading the inflammation.
