Simple and well-tolerated outpatient ultrasound procedure used to assess the patency of the fallopian tubes, as well as detect abnormalities of the uterus and endometrium.
The test requires the use of a contrast agent to visualise the patency of the fallopian tubes. The test may be performed by simply using an agitated saline/air mixture, or with a foam contrast agent . If the foam contrast is used, the test is then referred to as a HyFoSy procedure.
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.
