Saline Infusion Sonography
(Sonohysterogram)

A saline infusion sonogram is a specialised scan which involves the placement of a thin plastic catheter into the uterus via the cervix. Some saline (essentially water) is then instilled through the tube. A transvaginal ultrasound is performed at the same time. This test is usually ordered to investigate certain clinical conditions, such as abnormal bleeding or subfertility.

The procedure usually causes some discomfort; most people report that it is approximately like a Pap smear. You could take some paracetamol an hour prior to the procedure to make it more comfortable.

It is very important that the procedure is performed in the first half of the cycle, ie usually Day 5-10. Please contact us to book the procedure. One of our doctors will speak to you about the test after you make a booking.
