What Is Sonohysterography?
Sonohysterography, also called hysterosonography, is a simple ultrasound test that looks at the inside of the uterus. It uses sound waves and sterile saline (salt water) to create clear pictures. This test helps diagnose problems such as abnormal bleeding, fibroids, polyps, infertility, or changes in the shape of the uterus.
When Is Sonohysterography Recommended?
Your doctor may suggest this test if you have:
- Heavy or irregular menstrual bleeding
- Uterine fibroids or polyps
- Difficulty getting pregnant or repeated miscarriages
- Suspected scar tissue in the uterus
- Concerns about the shape of the uterus
Who Should Not Have the Test?
Sonohysterography is not done if you have a pelvic infection or if you are pregnant.
How to Prepare
- No special preparation is needed.
- Wear comfortable clothing; you may be asked to change into a gown.
- The test is usually scheduled for the week after your period ends, to ensure the best results.
What Happens During the Procedure?
- You will lie on your back, similar to a pelvic exam.
- A small ultrasound probe is placed in the vagina.
- A thin tube is inserted into the uterus, and a small amount of sterile saline is gently introduced to make the inside of the uterus easier to see.
- The ultrasound then shows detailed images of the uterine lining on a screen.
- The fluid is drained, and the instruments are removed once the pictures are taken.
The procedure usually takes about 20–30 minutes.
Benefits
- Safe and does not use radiation
- Gives a clearer view of the uterine lining than a standard ultrasound
- Helps detect growths, scarring, or other problems that may affect fertility or cause bleeding
Possible Risks
Sonohysterography is very safe. Some women may feel mild cramping or have light spotting afterward. Rarely, infection can occur.
After the Procedure
- You can go home right away and return to normal activities.
- Mild cramping, light spotting, or fluid leakage from the vagina is common for a short time.
- Call your doctor if you develop severe pain, fever, or abnormal discharge in the days following the test.
