Curettage generally refers to the procedure of scraping the uterus, which is a common surgical operation in gynecology. It is a common gynecological procedure, in which the doctor inserts a spatula into the uterine cavity and scratches around the uterine wall, and is mainly used for abnormal uterine bleeding, and for residuals in the uterine cavity after artificial abortion or medication abortion. In the case of abnormal uterine bleeding, the endometrial tissue needs to be scraped to stop the bleeding, and the pathological tissue can be sent to the laboratory to find out whether there is endometriosis. If there is residual tissue in the uterine cavity after abortion or medication abortion, you can use curettage to scrape out the placenta, fetal membranes, embryos and other tissues that remain in the uterus and are tightly attached to the uterine wall. Note that improper operation of the scraping procedure can damage the uterine wall and cause perforation of the uterus, so it is recommended that patients go to a regular hospital for the procedure.
