A HyCoSy is an ultrasound based examination of the Fallopian tubes assessing tubal patency. It involves an internal examination like a smear test and then a very thin tube is passed through the neck of the womb. The tube is no thicker than a very fine spaghetti strand and has a very small balloon on the tip which is inflated to seal the womb entrance.
Once the tube is in place the womb is scanned using an internal scan to check the position of the tube is correct.
A very small amount of effervescent fluid is then passed through the tube into the womb and fallopian tubes. Ultrasound waves bounce off air so giving us a very clear view of the tiny microbubbles as they pass through the fallopian tubes and spill out of the end of the fallopian tubes.
Your doctor needs the information to check that the tubes are open and are able to allow your eggs to travel freely down the tubes to allow fertilisation and implantation in the womb when you ovulate. It is performed on women who are finding it difficult to get pregnant or as a check after tubal surgery.
This method of checking the fallopian tubes is very safe; it requires no surgery or anaesthetic. It also means you are not exposed to X-ray and you will be able to discuss your results on the same day.
You will be asked to empty your bladder. You will then be made comfortable on the examination couch when an initial internal scan is performed to check your womb and ovaries are normal. This only takes a few minutes. It is very interesting and we will show you what we can and explain it all to you if you want to see.
Once we have this information we will then perform the HyCoSy scan which takes 15-20 minutes. You may feel period pain during the scan and if you do feel uncomfortable we will stop for a moment for you to recover and we will proceed when you feel more comfortable. You should take some pain relief prior to coming for the procedure such as paracetamol or ibuprofen.
Some women occasionally experience some cramping pain during and after the procedure but they will ease in a very short time.
We do recommend that you do not drive after the procedure so please bring someone with you take you or accompany you home on public transport.
Reactions to the medium are very rare and may result in feeling faint or abdominal pain. We will ensure you are well enough before you leave the clinic.
Rarely the procedure can cause infection which would become apparent up to 10 days after the procedure, if you suspect you have any signs and symptoms please contact your G.P. and inform him/her that you had the scan. Prophylactic antibiotics as a single does may be given.
You will be able to carry on life as normal an hour or two later but you may benefit from not going back to work immediately. You will know when you feel well enough to. The medium will leak out a little after the test and you will be more comfortable wearing a pad for a while and you can take whatever your normal pain killers are such as paracetamol. You will need to see your usual doctor to discuss all the results and whatever recommendations they have for you.
