A sonohysterogram is an ultrasound using a saline solution. This is done to diagnose problems with the shape of the uterus or abnormalities. The saline offers a clearer picture of fibroids or polyps in the uterus as well.
The sonohysterogram begins like a pap smear. A speculum is inserted and the cervix is washed with iodine. This is done to prevent infection. A catheter is inserted through the cervix and into the uterus. Saline is put through the catheter and fills the uterus with the solution.
As the uterus fills with fluid, it is common to feel some discomfort. This feels similar to menstrual cramps. Many doctors recommend their patients take ibuprofen prior to the procedure. This can help minimize discomfort.
You can watch the uterus fill with fluid on the ultrasound machine. This allows the doctor to get a better picture and detect any abnormalities. Pictures may be taken during the exam for later reference. The procedure only takes about ten to fifteen minutes.
Once the saline has filled the uterus, a transvaginal ultrasound will be done. This gives a more accurate picture of the inside of the uterus and the endometrium. If a biopsy is needed, a hysteroscopy may need to be done. In some cases, it can be done at the same time. Otherwise, you’ll need to schedule another appointment.
This procedure is done during the first half of the menstrual cycle. If you need to have a sonohysterogram, call to schedule it on the first day of your cycle. This will allow sufficient time to schedule prior to ovulation.
You may experience some mild cramping in the day or two following the sonohysterogram. Ibuprofen can be taken to reduce the cramping. You may experience a bit of light spotting. This is also normal. Call your doctor if you experience heavy bleeding, severe pain, fever or have chills.
