A saline sonohysterogram test is performed by a MRM physician. The physician will use a video monitor in the room to provide you with a direct view of what is being seen during the procedure. Before, during and after the procedure, the physician will answer your questions.
This test is used to examine a woman’s uterus and fallopian tubes.
What is a Saline Sonohysterogram Test?
A saline sonohysterogram is a procedure where a small volume of saline (salt solution) is inserted into the uterus while transvaginal pelvic ultrasound is performed. Two and three-dimensional imaging is used. This allows the lining of the uterus (endometrium) and the uterine muscle wall (myometrium) to be clearly seen on an ultrasound scan. This test can also determine if the fallopian tubes are open.
Timing for the Test
If you are trying to get pregnant in the same cycle as a saline sonohysterogram, make sure to schedule the test prior to ovulation so that there is no danger of “flushing out” a released egg or developing embryo.
Possible Side Effects and Risks
Although most women report only minor cramping, vaginal bleeding and short-term discomfort during this procedure, some women, especially those who have blocked tubes, report intense pain and are at risk for a flare up of an ongoing long-term pelvic infection with no symptoms before the procedure.
Preparing for the Saline Sonohysterogram Test
- We advise taking a pain relief medication about 30 minutes prior to the actual procedure.
- If there is a past history of pelvic infection, an antibiotic will be prescribed to prevent infection. You will be instructed to start the antibiotics one day prior to the procedure for three consecutive days duration.
What Can it Find?
- Structural abnormalities in the inner lining of the uterus called the endometrium, uterine wall and fallopian tubes
- Fibroid tumors that grow into the uterine cavity
- Abnormal formation of uterus from birth (congenital) or previous surgery
- Fallopian tube blockage
