A hysteroscopic diagnostic curettage requires a hospital stay of about 2-4 days, but the exact length of the hospital stay will depend on the patient’s condition, or it may not require hospitalization. If the patient’s condition is mild, the hysteroscopic procedure can be completed on an outpatient basis without hospitalization, or can be completed with only two days of hospitalization. If the patient’s condition is more complex, accompanied by other illnesses, or if the patient is older, hospitalization is required for the procedure. It takes 1-2 days to prepare for the surgery, including relevant examinations, laboratory tests, and pre-operative consultation, and the surgery takes one day. If the operation goes well, the patient can be discharged after 1-2 days of hospitalization. However, if bleeding, water intoxication, or uterine perforation occurs during the operation, the patient will need to be hospitalized for appropriate treatment and close observation, and the length of hospitalization will be prolonged depending on the condition of the patient. Therefore, there are many factors affecting the length of hospitalization for hysteroscopic diagnostic scraping, and treatment should be carried out in accordance with medical advice.
