Hysterosalpingoultrasonography (HSU)

In order for an egg and sperm to meet and fertilisation to take place, at least one of your follopian tubes must be open.

If passage through the fallopian tube is reduced, there is a greater risk of an ectopic pregnancy. For this reason, we recommend that you have an investigation to check whether your fallopian tubes are open or not. In fact, you must have such an investigation if you want to have hormone-stimulated insemination.

If both of your fallopian tubes are blocked, the only way for you to become pregnant is to try IVF. Most women’s fallopian tubes are normal, but if you have ever had a uterine infection, chlamydia, appendicitis, endometriosis or any other diseases that may have damaged your fallopian tubes, the risk of your fallopian tubes being narrowed or completely blocked is increased.

Chlamydia can cause a uterine infection that does not give rise to symptoms (a "silent infection”) that leads to narrowing or blockage of your fallopian tubes. You can have an investigation here in the clinic to check if your fallopian tubes are normal. StorkKlinik uses an ultrasound scanning method known as hysterosalpingoultrasonography or HSU. Hospitals and X-ray clinics may carry out investigations using a contrast medium and X-rays. This procedure is called hysterosalpingography or HSG.

This investigation takes place after menstrual bleeding has stopped and before the estimated time of ovulation, i.e. between Day 8-12 of your menstrual cycle. In most cases you can be inseminated during the same cycle. Before this investigation can be carried out, a cervical swab has to have been carried out at least three months beforehand, and you have to have tested negative for chlamydia. The chlamydia test can be carried out at StorkKlinik or by your own doctor/gynaecologist. Even the HSU investigation can be done on the gynaecologist’s couch.

Your cervix is washed out to ensure that no bacteria enter the cavity of your womb, and then a thin catheter is inserted. When this catheter is in place, a tiny balloon is filled with a small amount of air. This is done to ensure that the fluid that is subsequently injected into your womb does not run out through the cervix, but passes into the fallopian tubes. When the balloon is being filled, some women may be aware of some distension in the lower abdomen, but it does not hurt. Once the balloon has been filled with water, you will be scanned. During the scan, a mixture of sterile salt water and air is injected into the uterus while we monitor the flow of water through the fallopian tubes. If the fallopian tubes are blocked, the fluid will not be able to pass through. Some women experience pain similar to menstrual cramps during this examination. This examination is carried out without an anaesthetic, and most women can go straight back to work afterwards. Some women may benefit from taking painkillers, e.g. 1 gram of Panodil an hour before the examination takes place. You will have the opportunity to rest before you go home. There may be some thin discharge and even slight spotting after the procedure.

We recommend that you use a sanitary towel afterwards. The risk of infection is minimal; however, if you experience pain and fever within a few days after the examination, it is important for you to get in touch with a doctor in case you need treatment. You can take Panodil for pain but this is usually unnecessary. If both of your fallopian tubes are found to be blocked, our doctor will let you know what your options are. It may be recommended that you undergo a laparoscopy (where a tiny camera is inserted into your fallopian tubes), or you may be referred directly for IVF.
