Ultrasound of deeply infiltrating endometriosis using gel contrast (sonovaginography)

What is the ultrasound examination for deep infiltrating endometriosis with gel contrast?

The ultrasound examination for deep infiltrating endometriosis with gel contrast is a specialized test performed using a vaginal probe. Before the test, the doctor introduces a gel contrast into the vagina using a special catheter, allowing for a precise assessment of organs such as the anterior vaginal wall, bladder, ureters, posterior vaginal wall, rectum, and large intestine to detect any signs of endometriosis. Additionally, kidney function is assessed to exclude urinary retention that may be caused by ureteral narrowing due to endometriosis.

Who is it for?

This test is designed for women who may have deep infiltrating endometriosis, with symptoms suggesting the presence of this condition. It should be performed if symptoms such as the following are present:

• abdominal pain before menstruation,
• pain during intercourse,
• bladder pain,
• sacroiliac pain,
• infertility,
• diarrhea or constipation.

How to prepare for the test?

No special preparation is required for this test. It is best to perform it during the first phase of the menstrual cycle, after menstruation has ended, to ensure the most accurate results. It is important to consult a doctor prior to the test to rule out any contraindications, as the use of contrast gel is involved.

How does the test work?

The test takes about 30 minutes and is completely painless. At the start, the doctor introduces a contrast gel into the vagina, which helps to precisely visualize endometriosis changes in the pelvic organs. Then, using an abdominal probe, the kidneys are assessed to exclude urinary retention caused by ureteral narrowing. Standard evaluation also includes the cervix, uterus, and ovaries.

How long will it take to get the result and how to interpret it?

The results of the test are available immediately after its completion. The doctor will interpret the results in detail and, based on them, will make decisions regarding further treatment or diagnostics if abnormalities are detected.

Additional information

The test is safe and non-invasive, with the use of gel contrast allowing for a detailed assessment of pelvic organs. It is a crucial diagnostic method in cases where deep infiltrating endometriosis is suspected. Due to its nature, the test is particularly recommended for women with symptoms suggesting this condition who have not yet found an effective way to diagnose their issues.
