Endometrial polyps do not disappear by themselves. Most endometrial polyps are inflammatory hyperplasia of endometrial inflammation, and in some rare cases, they may be endometrial lesions or even endometrial cancer. Therefore, for endometrial polyps, it is better to do diagnostic scraping or to take endometrial polyps under hysteroscopy and send them for pathological examination, except whether there are lesions in the endometrium. The principle of treatment for most of the endometrial polyps is recommended to do electrodesiccation under hysteroscopy, and the cut specimens should be sent for pathological examination. Currently, the main methods of examination of endometrial polyps can be done, first of all, by ultrasound, which has a diagnostic compliance rate of 60%-70% for endometrial polyps. Ultrasound can show different degrees of thickening of the endometrium, and it may appear as uneven thickening, or there are hyperechoic clusters in the endometrium under ultrasound, which may be endometrial polyps. The diagnosis must be confirmed by diagnostic scraping or hysteroscopic endometrial biopsy.
