Whether or not the uterus needs to be cleared of uneven echoes in the uterine cavity cannot be generalized, but needs to be judged according to the size of the range of echoes, the specific cause and other factors. Generally speaking, if the range of uneven echoes caused by abortion is larger than 1cm, the uterus needs to be cleared. Uneven echo in the uterine cavity is a kind of gynecological clinical imaging results, suggesting that the patient’s uterine cavity there is fluid or tissue residues. This phenomenon is common in women with failed medication abortion, incomplete abortion, etc. Whether or not to clear the uterus can not be generalized. If the patient’s examination reveals a large echo range of more than 1cm, it is generally recommended to carry out the second treatment through the removal of the uterus as soon as possible, while if the echo range is small, the patient can first observe the menstrual cycle, and follow the doctor’s instructions to take medicines such as motherwort granules for the promotion of ovulation treatment. In addition to the above reasons, if a woman’s menstruation has not yet ended, endometritis, endometrial polyps and other endometrial pathologies may lead to uneven echoes in the uterine cavity when the patient is examined. Women who have not finished menstruation do not need to undergo uterine clearance surgery, while patients with endometrial pathology need to be treated first through hysteroscopic surgery, and if the operation is accompanied by conditions such as bleeding in the uterine cavity, or if there are residuals after polyp removal, they also need to undergo uterine clearance surgery. Clinical examination of women can lead to uneven echogenicity in the uterine cavity during the examination of a number of reasons, it is recommended that the patient first consult a doctor for examination, to clarify the specific causes under the guidance of the doctor to choose the appropriate way of treatment.
