Chronic endometritis, uterine adhesions, decreased menstrual flow, and secondary infertility may occur after diagnostic scraping, but the chances of this occurring are relatively low, and it is not considered a hazard, but only a negative effect. When endometrial scraping under hysteroscopy is required, it is often done when there is abnormal uterine bleeding or more uterine bleeding and the possibility of corresponding subsequent endometrial malignant hyperplasia needs to be excluded, or to reduce significant vaginal bleeding. If there is a clear indication for surgery, the corresponding diagnostic curettage needs to be performed. At this point, the corresponding subsequent effects are understood and the pros and cons are weighed, and when the pros outweigh the cons, endometrial curettage does need to be performed. When certain negative effects are accepted, endometrial curettage is still considered.
