A sonohysterogram is a unique type of ultrasound that allows your healthcare provider to examine the interior of your uterus. During a sonohysterogram, an ultrasound machine captures images of the structures and contours within your uterus while it is filled with saline solution.

This procedure assists your provider in identifying any problematic areas within your uterus and uterine lining (endometrium) that could be contributing to symptoms such as bleeding, pelvic pain, and infertility.

Healthcare practitioners use sonohysterography to help diagnose several medical conditions, including:

  • Uterine fibroids
  • Uterine polyps
  • Scarring inside the uterus
  • Abnormal shape of the uterus
  • Signs of endometriosis
  • Signs of endometrial cancer
  • Blockages in your fallopian tubes

Your doctor might advise this test if you have symptoms that suggest a problem with your uterus, such as:

  • Abnormal menstrual bleeding
  • Infertility
  • Repeated miscarriages
  • An abnormal pelvic exam


Who Should Not Get a sonohysterogram:

You should not get a sonohysterogram if you’re pregnant or if you have pelvic inflammatory disease (PID).

When is a sonohysterogram performed?

The optimal time for a sonohysterogram is after your menstrual period has concluded but before ovulation, typically between days 6 to 11 of your menstrual cycle, starting from the first day of bleeding. During this phase, the uterine lining is at its thinnest, allowing your provider to observe it with greater clarity. If you are postmenopausal, the procedure can be conducted at any time. If your cycle is unpredictable or bleeding is prolonged, please discuss the procedure with your physician.

Who performs the Sonohysterogram?

During the procedure, an ultrasound technologist captures images while a Radiologist conducts the examination. Subsequently, the radiologist, will analyze the results and prepare a report detailing their findings.This report is then shared with your healthcare provider to communicate the results to you.

During the test:

1. An ultrasound will initially be performed by a technologist.

2. A Radiologist will be performing the procedure. The Radiologist will insert a speculum into the vagina.

3. A catheter will be inserted through the speculum into the cervix.

4. A tiny balloon at the tip of the catheter will act as a stopper while fluid is injected into the endometrium. This fluid will allow us to better visualize the uterine cavity and lining.

5. The sonographer will then re-insert the probe and document any findings.

Please refrain from intercourse from the time your period begins until after the exam is performed so there is no chance of pregnancy. If there is any chance you may be pregnant please perform a pregnancy test before the procedure.

To minimize pain and cramping during the procedure, we offer our patients ibuprofen and 5 mg of oxycodone 1 hour before the procedure. Please notify us of any allergies. We also suggest the patient take 600 mg of Ibuprofen at home 3 hours before the procedure.

To minimize the risk of post-procedural infection, we prescribe a short course of antibiotics (doxycycline) for 3 days post-procedure. Please take the pills with food and notify us of any allergies.

You must have someone to drive you home (you cannot drive after taking oxycodone).

Post Hysterosonogram Instructions

1. In the majority of cases, there is no discomfort except for mild cramping.

2. For relief, take nonsteroidal anti-inflammatory medications (e.g. Advil, Motrin, or Ibuprofen) or Tylenol. Nothing should be inserted into the vagina for 24 hours (no tampons or douching).

3. Avoid heavy lifting or exercise for 24 hours.

4. If you develop fever, pain (greater than normal menstruation pain), or excessive bleeding, please contact your doctor directly. This may be a sign of infection.
