Whether or not a uterine scar diverticulum needs to be treated is determined by the patient’s specific condition. Scar diverticulum on the uterus is due to poor healing of the scar after cesarean delivery, the muscle layer at the uterine scar becomes thin and a large depression is formed at the base and in the uterine cavity, leading to a series of clinical symptoms, such as abnormal uterine bleeding or prolonged menstrual periods, increased menstrual flow, etc. Some diverticulae do not have too obvious symptoms and do not require special treatment. If the clinical symptoms are more pronounced, treatment may be undertaken. Treatment includes medication and surgery. The recommended medication is oral contraceptive pills, which will be observed after three months, while surgery can be performed by hysteroscopy or laparoscopy.
