What is Hysterosalpingo-Contrast-Sonography?
Hysterosalpingo-contrast-sonography (usually shortened to HyCoSy) is a simple ultrasound procedure used to examine the fallopian tubes, as well as detect any problems of the uterus and endometrium.
The test requires the use of a contrast fluid to visualise the fallopian tubes. Some women will require the use of a non-iodinated contrast agent called ExEm Foam.
The HyCoSy procedure is a safe and reliable alternative to the conventional hysterosalpingogram (HSG) which uses X-rays. No radiation or iodinated contrast material is used for a HyCoSy test.
Why would I need one of these tests?
Occluded (blocked) fallopian tubes are a common cause of infertility. Tubal occlusion can occur with a number of conditions including previous pelvic infection, severe endometriosis, previous appendicitis and pelvic adhesions. Many women will be unaware that these conditions are present and that tubal blockage has occurred.
A normal fallopian tube is not seen with regular ultrasound.
Even if the fallopian tube is blocked, it may still be difficult to see on regular ultrasound unless it is also filled with fluid (forming what is known as a hydrosalpinx). This is why a special test using a contrast agent such as ExEm Foam is useful, as it helps the doctor to visualise the fallopian tubes and assess whether they are patent (working).
