Hystero-Contrast Sonography (HyCoSy)

What is HyCoSy ?
HyCoSy is a short ultrasound guide outpatient procedure used to check if your
fallopian tubes are open. This is done as a part of investigations for subfertility.


How is the HyCoSy procedure done?
This involves an internal examination following which a fine tube (catheter) is passed
through the neck of the womb (cervix). Once the catheter is in place an ultrasound
(vaginal scan) is performed to check the location of the catheter. After confirming the
location of the catheter a small amount of contrast is inserted through the catheter
into the womb and the fallopian tube.

Are there any alternatives to this test?
Hysterosalpingogram (HSG) (refer HSG leaflet) and a Laparoscopy and dye
procedure under general anaesthesia are the alternatives to HyCoSy.
What are the benefits of HyCoSy?
This procedure does not require an anaesthetic or surgery and it does not have any
X ray exposure.

What will happen when I arrive at the department?

Some women experience
cramps on insertion of the catheter / contrast. Hence it would be advisable to take
painkillers (Ibuprofen / Paracetamol) at least an hour prior to the procedure.

contrast medium used is rare.
