HSG and HYCOSY for the examination of the fallopian tubes
If damages or any changes to the fallopian tubes are suspected, imaging examination procedures can also be applied.
Imaging procedures used may be the hysterosalpingogram (HSG), an x-ray imaging of the fallopian tubes using x-ray contract agents; and the Hysterosalpingo-contrast-sonography (usually shortened to HyCoSy), an ultrasound examination of the fallopian tubes in which a contract agent is injected into the fallopian tubes to access their patency (is routinely carried out at the KinderWunschKlinik Wels and Vienna).
HSG: What is visible on the x-rays is how the cavity of the uterus and the fallopian tubes fill with contrast agent. In this way any changes in the uterus cavity (myomes, scaring, polyps, etc.) or at the end of the fallopian tubes can be identified. The image also shows the patency of the fallopian tubes (whether they are clear or blocked). However, the examination does not provide information on the functioning and motility of the fallopian tubes. A short anaesthetic is normally required for this examination.
HYCOSY: Here an ultrasound and a contrast liquid are used to examine the patency of the fallopian tubes. For the examination, the doctor inserts a thin catheter into the opening of the cervix, through which the contrast agent is applied. In the ultrasound, the doctor is able to see if and how the contrast agent flows through the fallopian tubes. The examination can be carried out as an outpatient procedure and does not require any anaesthetic. However, some women experience pain similar to period pains. This examination is applied often, as it does not entail radiation exposure or anaesthetic. Allergic reactions to the contrast agent or an infection of the womb (metritis) as a result of the procedure are very rare.
