    HSG (HYSTEROSALPHINGOGRAPHY)

    Hysterosalpingography (HSG), also known as uterosalpingography, is a radiologic procedure to investigate the shape of the uterine cavity and the shape and patency of the fallopian tubes. This means it is a special x-ray using dye to look at the womb (uterus) and Fallopian tubes. It injects a radio-opaque material into the cervical canal and usually fluoroscopy with image intensification. A normal result shows the filling of the uterine cavity and the bilateral filling of the fallopian tube with the injection material. 

    It is useful to diagnose uterine malformationsAsherman’s syndrometubal occlusion, and pelvic inflammatory disease and used extensively in the work-up of infertile women. It has been claimed that the chance of pregnancy increases after HSG has been performed

     

    What are some common uses of the procedure?

    Doctors primarily use this exam to examine why you might be having difficulty becoming pregnant. The doctor looks at the openness of the fallopian tubes, the shape, and structure of the uterus, and any scarring within the uterine or nearby peritoneal (abdominal) cavity.

    The exam also evaluates the openness of the fallopian tubes and checks the effects of tubal surgery. These effects include:

    • Blockage of the fallopian tubes due to infection or scarring
    • Tubal ligation
    • Closure of the fallopian tubes in a sterilization procedure and a sterilization reversal
    • Re-opening of the fallopian tubes following sterilization or disease-related blockage

    The exam can investigate repeated miscarriages resulting from congenital or acquired uterine problems such as:

    • Uterine fibroids
    • Endometrial(uterine) polyps
    • Adhesions
    • Congenital problems (uterine anomalies)
    • Tumors

    How should I prepare?

    Schedule your exam for seven to 10 days after the first day of your menstrual period, but before ovulation. This is the best time for the exam.

    Do not have this procedure if you have an active pelvic infection. Tell your doctor and technologist if you have any signs of pelvic infection or an untreated STD. Tell your doctor if you are allergic to iodinated contrast.

    Before the procedure, you may take over-the-counter medication to minimize any discomfort. Some doctors prescribe an antibiotic prior to and/or after the procedure.

    You should inform your us of any medications being taken and if there are any allergies, especially to iodinated contrast materials. Also, inform us about recent illnesses or other medical conditions.

    You will need to remove some clothing and wear a gown for the exam. Remove any metal objects or clothing in the pelvis that might interfere with the x-ray images.

    Women should always tell their doctor and technologist if they are pregnant. Doctors will not perform many tests during pregnancy to avoid putting the fetus at risk. If an x-ray is necessary, the doctor will take precautions to minimize radiation exposure to the baby.

    What are the benefits

    • This exam is minimally invasive; complications are rare.
    • It can offer valuable information on problems getting pregnant or carrying a fetus to term.
    • It can potentially open blocked fallopian tubes to allow you to become pregnant in the future.
    • No radiation remains in a patient’s body after an x-ray examination.
    • X-rays usually have no side effects in the typical diagnostic range for this exam.
