Transvaginal pelvic ultrasound
Transvaginal ultrasound provides detailed images of the uterus, endometrium and ovaries. It is used to investigate gynaecological symptoms, assess previously identified changes and monitor the condition of the reproductive organs over time.

How is a transvaginal ultrasound performed?
During the examination, the doctor uses a specialised slim probe covered with a protective sheath and gel. It is gently inserted into the vagina. As the probe is positioned close to the pelvic organs, it provides detailed images of their structure and helps identify even small abnormalities.
Unlike an external ultrasound performed through the abdominal wall, a transvaginal scan usually does not require a full bladder. The internal approach allows the doctor to obtain detailed views of the uterus and ovaries.
Before the procedure, the doctor explains what to expect. If a transvaginal examination is not suitable for you, an alternative imaging method can be discussed.
Specialists
What can a transvaginal ultrasound assess?
- Uterus – its position, size, shape and wall structure are assessed, including the presence of uterine fibroids.
- Endometrium – the inner lining of the uterus is examined for thickness and structural changes, taking the menstrual cycle phase into account.
- Ovaries – the doctor assesses their size, structure, cystic formations and other findings.
- Ovarian follicles – when indicated, their number, size and changes throughout the menstrual cycle can be monitored.
- Pelvic abnormalities – ultrasound can help identify structural changes that may require further investigation.
- Free fluid in the pelvis – its presence is assessed in the context of symptoms and other examination findings.
- IUD position – when needed, the scan can be used to check the position of an intrauterine contraceptive device.
How to prepare for a transvaginal ultrasound
A special diet or fasting is usually not required before a transvaginal ultrasound. The main preparation step is to empty your bladder immediately before the examination, as this helps obtain the necessary images.
If you are menstruating, mention this when booking if you are unsure whether the scan can take place on your scheduled date. A tampon or menstrual cup must be removed before the procedure.
Bring previous ultrasound reports with you, if available. Comparing earlier and current findings helps the doctor assess how any identified changes have evolved over time.
Tell your doctor before the examination if you are pregnant or think you might be pregnant.
