According to medical data, fallopian tube abnormalities account for up to 40% of female infertility. Thus, fallopian tube tests are considered essential in the investigation of infertility, as they provide valuable information about a woman's fertility. The most common methods for investigating tubal patency include X-ray hysterosalpingography (HSG) and contrast-enhanced hysterosalpingography (HyCoSy). Until recently, our knowledge was limited to the classic hysterosalpingography (HSG or YSG), which is performed in a radiology laboratory using X-rays and a contrast medium administered through the cervix. Despite the useful information it offers, this particular method is accompanied by increased exposure to radiation and the risk of an allergic reaction to the contrast agent. In addition, it is characterized as "unpleasant" by women and often causes a feeling of discomfort during and shortly after the examination.
HyCoSy and, later, HyFoSy (using gel foam as contrast) were introduced as an alternative to HSG, thus avoiding exposure to the risks of iodine allergy or x-ray radiation. These are ultrasound-based techniques that allow the detection of fallopian tube abnormalities in real time and are safer for the patient. THE Ultrasound salpingography, is the most modern technique for checking the patency of the fallopian tubes, using foam contrast agent (HYFOSY) which is easily detected during intravaginal ultrasound.
What are the advantages of HyFoSy?
- No radiation or iodinated contrast material is involved.
- It is painless, with little to no discomfort during the exam, as the injected fluid causes less irritation than the dye used in HSG.
- It does not require hospitalization or the use of a general anesthetic,
- Ultrasound examination allows evaluation of other pelvic structures
How exactly is HyFoSy done?
First, a transvaginal scan is performed to assess the pelvic anatomy. After that, a speculum is placed in the vagina and the cervix is cleaned with an antiseptic solution. A thin sterile plastic catheter (2mm) is then passed through the cervix. Once the tip of this catheter is in the uterine cavity, the small balloon on the tip inflates to hold the catheter in place. The vaginal probe is inserted again by taking the speculum out. The scan is performed as foam gel is injected through the catheter, allowing the fallopian tubes and surrounding pelvic areas to be visualized.
How long does the process take?
It usually takes about 10-15 minutes to complete the process.
When is the best time to do HyFoSy?
It is best done between days 5 and 10 of the menstrual cycle, taking the first day of your period as day 1.
Will I need pain relief for the procedure?
A single dose of 2 Nurofen tablets, or similar, is recommended – 1 hour before the test. If you cannot tolerate anti-inflammatory drugs, 2 Panadol tablets can be taken as an alternative. Some women find the procedure slightly more uncomfortable than others.
Will I need to take antibiotics before the procedure?
It is generally not necessary. However, it may need to be considered in some cases and should be discussed with your doctor. The prescription is given by your doctor and the antibiotics must be taken 2 hours before the test.
What other information should I know about the procedure?
You may experience vaginal discharge for about 24 hours after the procedure. Most women tolerate the procedure well, although some have more severe cramping. For this reason, you may consider having a support person with you who can drive you home.
summarizing
Hyaluronic Foam Ultrasound, (HYFOSY) is generally considered a safe and effective procedure for evaluating female fertility. It is a non-invasive technique that combines ultrasound imaging with the use of a foam contrast agent to evaluate the uterine cavity and fallopian tubes.
- Security: HYFOSY is considered safe and complications are rare. The procedure is usually performed on an outpatient basis, and the use of ultrasound and contrast foam reduces the risks associated with radiation exposure compared to traditional X-ray procedures such as hysterosalpingography (HSG).
- Effectiveness: HYFOSY is effective in providing real-time images of the uterine cavity and fallopian tubes. It can help identify issues such as blockages, abnormalities or other factors that may affect fertility. The use of foam contrast agent enhances visibility and improves the accuracy of the examination.
- Patient comfort: Compared to some other fertility tests, many women find HYFOSY more comfortable. It is generally considered less invasive and less uncomfortable than procedures such as hysterosalpingography.
- Diagnostic value: HYFOSY provides valuable diagnostic information for healthcare providers. By imaging the reproductive organs and detecting any abnormalities, it can help diagnose fertility-related problems, allowing more informed decisions about appropriate treatment options.
While HYFOSY is generally well tolerated and safe, it is essential to discuss any concerns or questions with your healthcare provider before undergoing the procedure. Each person's situation is unique, and your doctor can provide personalized information based on your medical history and specific fertility concerns.
