In the clinic, there are often patients who come to me for consultation because of amenorrhea, significantly reduced menstrual flow or infertility due to re-cleaning after abortion or abortion and scraping, and they invariably show great regret for re-cleaning, so I would like to ask all female patients to please remind them in the future after reading this article of mine or after they or their sisters encounter similar situations that they can choose hysteroscopic surgery to remove residues. After miscarriage or scraping, menstruation does not turn or amenorrhea or abnormal menstrual flow leads the patient to see the doctor again. After ultrasound, the doctor finds that the uterine cavity is still occupied, i.e. there are still residues, so the patient is cleared again. Because of the fear that there is still residue when the uterus is cleared again leads to possible over-treatment by the doctor during surgery i.e. excessive scraping. So a bigger problem occurs i.e. damage to the endometrium. The heavy and aggravated decrease in menstrual flow or amenorrhea. Therefore, women who are in a similar situation are advised to opt for hysteroscopic removal of intrauterine residues. Hysteroscopic removal of intrauterine residues is done by inserting a hysteroscope to check the size of the residue, and if there are adhesions, they can be separated and removed under visualization. The residue is resolved without the need to remove the uterus. So there is no scraping of the endometrium. The damage to the endometrium is not aggravated.
