Uterine cleanup, also known as a procedure to clean out the uterine cavity, is a form of uterine surgery and is mainly used in cases such as medication abortion, incomplete abortion, and natural abortion that is not clean. The purpose is to remove the residual tissue from the uterine cavity to help the uterus recover and reduce the possibility of bleeding or infection. The procedure includes diagnostic and therapeutic curettage. Diagnostic scraping is mainly applied to unexplained uterine bleeding, which requires diagnosis of the cause of bleeding, scraping, and sending the scraped tissue to pathology for symptomatic treatment of the cause of bleeding; therapeutic scraping is taken because the uterine cavity bleeds more than once and needs to be stopped quickly. The above two types of scraping are slightly different from clearing the uterine cavity of residues after a medication abortion or an abortion. The requirements for the surgeon are high because it is the second operation after abortion, the uterus is very soft and the wall is very thin, so if the operation is not done properly it may cause a series of bad consequences such as uterine perforation, intrauterine infection and uterine adhesion. Therefore, women who need to do the operation to clear the uterus should choose a regular medical institution and an experienced surgeon, so as to guarantee the safety and success rate of the operation.
