Sonohysterography (Interventional)
Saline infusion sonohysterography (SIS) or saline ultrasound uterine scan.
Uses a small amount of saline (salt solution) inserted into the uterus (or womb) that allows the lining of the uterus (endometrium) to be clearly seen on an ultrasound scan.
Ultrasound is the term used for creating pictures or images using high-frequency sound-waves. The pictures are obtained using an ultrasound transducer.
Ultrasound transducers transmit high-frequency sound waves that are converted into electrical impulses that produce a moving image of the inside of the body on a screen.
Other Treatments
- Suspected abnormalities of the uterus – either ones you were born with or new ones eg. fibroids.
- Further evaluation of abnormalities seen on transvaginal scan eg. in women receiving tamoxifen therapy for breast cancer.
- Investigation of sub-fertility and recurrent miscarriages.
- If the lining of the uterus was not able to be seen clearly on routine scanning.
You should not have the procedure if you are pregnant or may be pregnant at the time of the examination or you have acute pelvic infection or unexplained pelvic tenderness which may be due to pelvic inflammatory disease.
This technique is used to detect abnormalities of the uterus and the endometrium. Essentially a small amount of fluid is injected into the uterus through a fine tube to outline the uterine cavity. Other structures may be examined if indicated ie. kidneys, bowel and bladder.
Whilst you may experience some mild discomfort, this is not a painful procedure and therefore no anaesthesia is required. Some patients find a single dose, 1 hour prior to the procedure, of simple analgesia eg. Naprogesic helpful.
