Saline Infusion Sonography (SONOHYSTEROGRAPHY)
Sonohysterography, sometimes known as saline infusion sonography, is minimally-invasive outpatient ultrasound technique that produces images of the inside of your uterus. A saline fluid allows for more detailed imaging, as it is injected through the cervix into the uterus. The ultrasound is used to create images of the endometrial cavity.
Saline Infusion Sonography
- It is best to perform sonohysterography between day 5-12 of your menstrual cycle. At this time, the endometrium is at its thinnest—ideal for determining whether it is normal and healthy.
- The procedure should not be performed if the patient is pregnant.
How is the saline infusion sonography performed?
- The procedure begins with a trans-abdominal ultrasound examination prior to the saline injection. The patient will then be asked to assume the lithotomy position (lying on back with feet in stirrups) to begin the ultrasound examination. A probe will be placed in the vagina.
- Next, a speculum is introduced and a narrow catheter is placed in the vagina, through the cervix, and into the uterine cavity (this may cause mild cramping). Next, the sterile saline solution (salt water) will be slowly injected in the cavity to fill the uterus, helping to outline the uterine walls in the images.
- These images will assist in establishing a treatment and management plan for a patient’s specific condition.
- Following the examination the patient will be asked to remain in the waiting area for several minutes to monitor any discomfort. Over the counter medications should be able to minimize any discomfort that some women might feel. You may experience vaginal spotting following this procedure – this is entirely normal. Once the ultrasound procedure is completed, you will be able to return to normal activity immediately.
You can expect this procedure to last about 30 minutes
