Uterine polyps can cause abnormal bleeding from the uterus, in this case in the form of constant vaginal bleeding, and after the appropriate ultrasound examination, hysteroscopy is required. If endometrial polyps or cervical canal polyps are found under hysteroscopic conditions, the corresponding polypectomy will be performed. After polypectomy, intermittent, small amount of vaginal bleeding for 7-10 days is normal. If the endometrial polyp is still benign, it is better to apply progesterone to control the recurrence of the polyp in order to reduce the likelihood of recurrence. If the pathological results of the polyps are suggestive of malignant or even malignant hyperplasia, further surgical management is required.
