It is a special type of ultrasound (sonar) in which a small amount of sterile saline solution is inserted into the uterine cavity through a thin catheter, then a vaginal ultrasound is performed at the same time. The solution helps to expand the uterine cavity, making the endometrial lining very clear in the image. Why is this examination requested? It is used to detect: Polyps inside the uterus Fibroids inside the cavity Intrauterine adhesions Reasons for delayed pregnancy Reasons for abnormal bleeding Is it painful? It causes slight discomfort or mild cramping similar to menstrual pain. It usually takes only 10 to 15 minutes. No anesthesia is needed in most cases. When is it performed? Often immediately after the end of the menstrual cycle (days 5–10 of the cycle) to ensure the endometrial lining is thin and clear.
