Hysterosalpinogram (HSG)

Focuses on endometrial cavity and patency of fallopian tubes.  Indications include, but are not limited to:

  • Indentify obstructed fallopian tubes
  • To ensure proper Essure® device placement
  • To visualize polyps / fistulas

Exam is performed by Gynecological clinician, with imaging and interpretation provided by a Radiologist.

The HSG procedure is used to determine the size, shape and location of your uterus and fallopian tubes.  Procedure Duration: 45-60 minutes.

Patient Preparation:
There is no preparation for this exam, however, your physician may have you take a laxative the evening before the procedure.

Please make sure the tell your doctor or the technologist if you have any allergies to medications, especially to radiology contrast (dye).  If you have had any contrast (dye) reactions in the past you may need to pre-medicate.  Please make your physician aware of this prior to your visit, as well as your technologists at the time of  your procedure.

Be sure to use the lavatory and completely empty your bladder just prior to the procedure.

Upon arrival to the radiology department, you will change into a gown and robe provided by the hospital.  You are required to remove all clothing from the waist down.  A 'Personal Belongings' bag will be provided so that you may take your clothes to the procedure room with you.

Your privacy and comfort will be maintained at all times.

**NOTE:  If you are a woman of childbearing age, the technologist will ask if there is any possibility of pregnancy.

During the procedure:
A radiologist (doctor), a gynecologist (doctor or clinician) and a registered technologist(s) will perform the procedure.  Please feel free to ask any questions at any time during your procedure. A registered technologist will go over some medical history and your medication list with you prior to the procedure.  She/he will explain to you what your procedure requires.  You will be required to lie flat on an x-ray table.  The table moves, tilts and is attached to a fluoroscope, (an x-ray unit that works with a television/computer screen).

Once on the x-ray table, the doctor performing the procedure will ask you to bend your knees up, in such a way so the she has access to your vagina.  After cleansing the area, the gynecologist will insert a speculum into your vagina followed by a small catheter.  Then the radiologist will enter the room to run the x-ray machine.  The gynecologist will inject contrast dye through the catheter to fill your uterus and fallopian tubes.  You may feel pressure and cramping.  It is important to let the doctors know what you are feeling!

The radiologist will be taking radiographic images of the flowing contrast as it fills your uterus and spills out of your fallopian tubes (or no spilling in the case of testing Essure® placement).  You may have to tilt from side to side for better visualization of your internal organs.

Once the procedure is finished, the remaining contrast dye will empty out of the vagina due to gravity or be safely absorbed by the body.  The contrast dye is colorless and will feel sticky until completely washed off.  You will then be directed to a nearby restroom to get cleaned up and dressed.  A pad will be provided for any excess drainage of contrast dye.

The technologist will provide discharge instructions in both verbal and in written form once the procedure is complete.  You will be escorted out of the department through reception.

Post-procedure Information:
The radiologist (doctor) will read the images and dictate a report.  Your physician will receive a report of the findings within 3 business days and should advise you of the results.  You may continue to feel pressure and cramping, but that should go away in several hours.  You might also have some spotting.  Please be sure to follow the discharge instructions given to you after your procedure.
