WHAT: A hysteroscopy is a way for your doctor to look at the lining of your uterus. The tip of the hysteroscope is put into your vagina and gently moved through the cervix into the uterus. The hysteroscope has a light and camera hooked to it so your doctor can see the lining (endometrium) on a video screen.
WHY: The hysteroscope allows for easy visual access to the interior of the cervix and uterus to assess the lining of these structures. Therapeutic maneuvers, such as taking a tissue sample, removal of polyps or fibroid tumors, or preventing bleeding with cautery may be performed during a hysteroscopy procedure.
HOW: A vaginal speculum is often inserted prior to the procedure to facilitate insertion of the hysteroscope through the uterine cavity. Depending upon the exact type of hysteroscope that is used, dilation of the cervical opening with surgical instruments may be necessary. After insertion of the hysteroscope, fluid or gas is injected to distend the uterine cavity and allow for better visualization.
