The presence of flocculent material in the uterine cavity is often detected by ultrasound examination. This condition is often seen after abortion, medication abortion, or after a cleansing procedure, etc. If this occurs, it is possible that there is residue in the uterine cavity. It is recommended to combine this with the clinical history, and if the residue is relatively large, it is recommended to perform a cervical operation if necessary, and to send the removed tissues together with pathological tests for pathological diagnosis. If this condition is accompanied by pain in the lower abdomen and odorous vaginal discharge, first of all, anti-inflammatory treatment is needed. After anti-inflammatory treatment, there is no pain in the lower abdomen and no odor in the discharge, and then consideration should be given to clearing the uterus, otherwise premature clearing, without anti-inflammatory treatment, may lead to the spread of inflammation and cause serious clinical symptoms.
