After 25 years of placing the IUD, whether it is good to take out the IUD needs to be determined firstly whether the position of the IUD is normal or not, whether there is any IUD breakage, incarceration, uterine cavity adhesion, cervical atrophy and so on, the specific difficulty of removing the IUD should be combined with the intraoperative situation to see that those who are not accompanied by the above mentioned situations generally have a smoother process of removing the IUD. If you want to take out the IUD after 25 years, you should do ultrasound examination first to confirm the position of the IUD and the situation in the uterine cavity, and then do the procedure of removing the IUD. Because the IUD has been in place for a long time, there may be cases such as IUD inlay, uterine cavity adhesion, etc. Also, after 25 years of IUD placement, the woman may have already gone through menopause, and all these factors will make it more difficult to remove the IUD, resulting in prolonged operation time and increased pain for the patient. Therefore, if necessary, in doing IUD removal surgery can be timely communication with the patient for anesthesia to reduce the pain. Some women although the birth control ring time is relatively long, but the position of the birth control ring is better, there is no uterine cavity adhesion or ring of incarceration, fracture, the removal of the ring surgery is still relatively smooth. Therefore, whether it is good for a woman to remove her IUD after 25 years of placement is related to the location of the IUD and the condition of the uterine cavity, which can only be clarified after examination.
