Diagnostic scraping generally refers to diagnostic scraping, which clinically involves scraping a bit of endometrium down for examination. Diagnostic scraping is widely used in clinical practice, mainly through scraping part of the tissue for testing, in order to diagnose abnormal uterine bleeding, menstrual disorders, infertility, suspected endometrial tuberculosis and other conditions. Diagnostic curettage can also be used to diagnose and treat patients with prolonged and heavy vaginal bleeding due to residual tissue in the uterine cavity or incomplete shedding of the endometrium. Since diagnostic curettage will cause local tissue damage, a small amount of vaginal bleeding after the examination is normal, and generally does not require special treatment. If the amount of bleeding after the examination is large or accompanied by abdominal pain and other symptoms, we need to be vigilant about perforation of the uterus and other conditions, and we need to consult a doctor in a timely manner. It is recommended to consult a regular hospital for diagnostic scraping to ensure the accuracy of the test results. Avoid excessive tension during the examination process, and actively cooperate with the medical staff, if accompanied by symptoms of discomfort, you should promptly communicate with the medical staff, and stop local scratching.
