The mechanization of the uterine cavity residue refers to the process of the tissue changing from hard to soft, in general, the residue more than three months will almost start to mechanize, so there is no difference between six months and two years of residue mechanization. When there is residue in the uterine cavity, it is easier to strip it out of the uterine cavity and clean it up in the beginning due to the relatively short period of time. As time goes on, it grows into hardened tissue in the uterine cavity and adheres to the uterine wall. This may interfere with the normal menstrual cycle and tend to cause prolonged menstrual bleeding or drenching vaginal bleeding, and in severe cases of uterine adhesions, it may also interfere with a woman’s ability to conceive. If the residue is more serious, it may need to be cleaned up again by hysteroscopic electrosurgery under the hysteroscope in order to completely remove it, which is more likely to damage the uterine lining. Therefore, if you find residue in the uterine cavity, it is recommended that you seek medical attention in time to avoid delaying treatment.
