Hysterosonography (SIS) Hysterosonography, also known as Saline Infusion Sonography (SIS), is an imaging procedure that uses sound waves via a transvaginal ultrasound while sterile normal saline is injected at the same time. This allows images to be obtained of the inside of the uterus and the surrounding tissues. It is a safe and painless procedure that does not involve X-rays. Procedure: After emptying her bladder, the patient is asked to wear a special gown to help prevent infection. First, an internal (transvaginal) ultrasound is performed. After disinfection and placement of a speculum, a small, flexible plastic catheter is inserted into the cervix. Sterile normal saline is then infused into the uterine cavity through the catheter. Ultrasound imaging is performed simultaneously to examine the inside of the uterus and the surrounding tissues. Answers to Frequently Asked Questions: Is the saline injected with a needle? No. The syringes used in this procedure (2 cc and 50 cc) are only for flushing, and no needle is used. How long does the procedure take? Approximately 10 to 15 minutes. Is any special preparation required? No special preparation is needed. However, a light breakfast is recommended to help prevent possible weakness. Avoid heavy or gas-producing foods, such as milk and eggs. Is rest required after the procedure? After the procedure, the patient rests in the department for about 20 to 30 minutes. Normal daily activities may then be resumed without restriction. Are painkillers needed for this procedure? On the day of the appointment, a painkiller is given about 15 minutes before the hysterosonography to help prevent possible spasms. Is there a risk of bleeding? This procedure does not usually cause bleeding. However, slight spotting may occasionally occur for a few days. Why is it necessary to have a companion? Having a companion is required to help reduce the patient’s stress and assist with admission procedures and preparation of supplies. When will the results be ready? The results are usually available on the same day, approximately one hour after the hysterosonography is completed.
