A sonohysterogram uses ultrasound to look at the inside of your uterus. A salt (saline) solution is put in the uterus for a clearer image.
Ultrasound images from a sonohysterogram can help find the cause of bleeding or problems with getting pregnant.
Unlike a hysterosalpingogram, a sonohysterogram doesn't use X-rays or an iodine dye. The test can be done in a doctor's office, a hospital, or a clinic.
It's usually done because a normal ultrasound has not found the cause of heavy bleeding, repeated miscarriages, or trouble getting pregnant.
This imaging test checks the inside of the uterus for such things as:
A sonohysterogram may be more accurate than a hysterosalpingogram for finding fibroids and polyps.
First, schedule your sonohysterogram appointment for:
On the day of your test:
You may be asked to sign a consent form that says you understand the risks of the test and agree to have it done.
Talk to your doctor about any concerns you have about the need for the test, its
risks, how it will be done, or what the results will mean. To help you
understand the importance of this test, fill out the
medical test information form(What is a PDF document?).
A sonohysterogram can be done in a doctor's office, a hospital, or a clinic. It usually takes about 15 to 30 minutes.
Your doctor may advise you to take an over-the-counter pain medicine before your appointment. This may help prevent cramping pain during the test.
Before a sonohysterogram, you empty your bladder. You then take off your clothes below the waist. You are given a gown or sheet to cover up with during the test.
For the test, you sit on the edge of a padded table. Then you lie back with your feet raised and supported by stirrups.
A sonohysterogram is done in several steps.
After the test, the ultrasound wand and then the tube are removed. Some of the saline solution flows through the fallopian tubes into your abdominal cavity. But most runs out of your cervix and vagina.
You probably will feel some cramping like
menstrual cramps from the fluid being injected into your uterus. After the test, you can expect a watery discharge for a few hours.
There is a small chance of pelvic infection after a sonohysterogram.
You may have cramping, spotting, or a watery discharge.
Call your doctor right away if you have:
A sonohysterogram uses ultrasound to show the inside of the uterus.
The shape of the uterus is normal.
No objects (such as an
intrauterine device, or IUD), tumors, or growths are
seen in the uterus.
The uterus may have an abnormal shape or structure.
The uterus may have abnormal growths or masses, such as scar tissue, fibroids, or polyps.
The uterus may show
tissue (called a septum) that divides the uterus.
There are times when you may not be able to
have the test or when the results aren't helpful. This may be:
Your doctor will not perform a sonohysterogram if you are pregnant or have a pelvic infection.
A sonohysterogram doesn't show how well the fallopian tubes are working. When there is a question about the tubes, a hysterosalpingogram is used.
For looking at the uterus only, a sonohysterogram is a good choice because it:
