What is hysteroscopy?
Hysteroscopy is used to diagnose or treat problems of the uterus. A hysteroscope is a thin, lighted telescope-like device. It is inserted through your vagina into your uterus. The hysteroscope transmits the image of your uterus onto a screen. Other instruments are used along with the hysteroscope for treatment.
One of the most common uses for hysteroscopy is to find the cause of abnormal uterine bleeding. Abnormal bleeding can mean that a woman’s menstrual periods are heavier or longer than usual or occur less often or more often than normal. Bleeding between menstrual periods also is abnormal.
Hysteroscopy also is used in the following situations:
- Remove adhesions that may occur because of infection or from past surgery
- Diagnose the cause of repeated miscarriage when a woman has more than two miscarriages in a row
- Locate an intrauterine device
- Perform sterilization, in which the hysteroscope is used to place small implants into a woman’s fallopian tubes as a permanent form of birth control
Before the procedure, you may be given a medication to help you relax, or general anesthesia or local anesthesia may be used to block the pain. If you have general anesthesia, you will not be awake during the procedure.
Hysteroscopy can be done in a doctor’s office or at the hospital. It will be scheduled when you are not having your menstrual period. To make the procedure easier, your health care provider may dilate (open) your cervix before your hysteroscopy. You may be given medication that is inserted into the cervix, or special dilators may be used.
A speculum is first inserted into the vagina. The hysteroscope is then inserted and gently moved through the cervix into your uterus. Carbon dioxide gas or a fluid, such as saline (salt water), will be put through the hysteroscope into your uterus to expand it. The gas or fluid helps your health care provider see the lining more clearly. The amount of fluid used is carefully checked throughout the procedure. Your health care provider can view the lining of your uterus and the openings of the fallopian tubes by looking through the hysteroscope. If a biopsy or other procedure is done, small instruments will be passed through the hysteroscope.
