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.
Schedule your test for when you won't be having your period. Your doctor may suggest that the test be done soon after your period ends and before your ovary releases an egg (ovulates). This timing allows your doctor to see the inside of your uterus better. It also avoids doing the test when you could be pregnant.
Your doctor may have you take an over-the-counter pain medicine, such as ibuprofen, about an hour before your test. This can help with cramps and pain during the test.
You may want to bring a sanitary pad. Some of the saline solution may leak out after the test. You also may have some slight bleeding.
A sonohysterogram can be done in a doctor's office, a hospital, or a clinic.
Before the test, 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 and legs supported by footrests.
A sonohysterogram is done in several steps.
After the test, the ultrasound wand and then the tube are removed. Most of the saline solution will leak from your cervix and vagina.
You may feel some pressure as the transducer is put into your vagina. You probably will feel some cramping (like menstrual cramps) from the fluid being injected into your uterus.
There is a small chance of pelvic infection after a sonohysterogram.
The shape of the uterus is normal.
No objects (such as an intrauterine device, or IUD), tumours, 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.
