A Saline Sono-Hysterosalpingogram (SonoHSG) or Hysterosalpingo-contrast-sonography (Hycosy) is often requested in the investigation of infertility and possible conditions regarding the internal lining of the uterus (endometrium) such as polyps or tubal blockages. It is performed in ultrasound and saline (sterile water) is injected into the uterus. No xray radiation is used in this procedure.
Your preparation requirements
A sonoHSG or Hycosy is performed between day 7-10 of your menstrual cycle. Please ring on the first day of your period to arrange your booking. This is to ensure that the procedure does not interfere with an early pregnancy. We ask that you come well hydrated and not go to the toilet as a pregnancy test will need to be performed prior to your study.
What to expect
You will be required to change into a patient gown for this procedure with your underwear removed. A baseline transvaginal ultrasound (see Pelvic Ultrasound Patient Information sheet) is performed to evaluate the uterus and ovaries prior to commencing the procedure.
Our Radiologist will insert a speculum into the vagina and place a very small catheter into the uterus. This is held in place by inflating a little balloon to stabilize its position. This may cause some lower abdominal cramping like symptoms that should settle. The speculum is then removed and the ultrasound probe is re-inserted. Then the saline is injected and images are taken. After the images are documented, the ultrasound probe is removed and then the Radiologist will deflate the balloon and remove the catheter.
Please allow 60 minutes for your examination.
After your procedure
The following points should be considered following your saline HSG procedure:
- Blood stained fluid loss can be experienced for 24 hours after your procedure (avoid using tampons)
- Some pelvic cramping can be experienced and a mild analgesia (eg Nurofen, Paracetamol) can be taken either prior to, or after your procedure
- If severe cramping, pain or fever present within 48 – 72 hours after your HSG then you must contact your doctor immediately or present to an emergency department
If you have any further questions, please don’t hesitate to contact us or consult your referring physician.
