SIS is a specialized technique used to obtain extremely detailed images of the uterine cavity and is often used to identify the cause of abnormal uterine bleeding. The procedure is performed by a gynecologist or advanced nurse practitioner specializing in reproductive medicine. A speculum is used to access the cervix and a thin catheter is passed into the uterine cavity. Sterile saline is gradually injected into the uterine cavity. This allows a clear demonstration of any structural abnormalities within the uterus.
No preparation is needed for this exam.
