Transvaginal ultrasound: how is it performed?

Ultrasound transvaginal is a simple and quick examination, very useful for thoroughly analyzing the female genital organs. It is based on ultrasound technology and has no side effects. Thanks to this examination, it is possible to study the morphology of the vagina, uterus, and ovaries and identify any benign or malignant alterations. Transvaginal ultrasound can be performed at any time during the menstrual cycle, menopause, and pregnancy. Let’s see in detail how it works.

How transvaginal ultrasound works

In transvaginal ultrasound, the probe, covered with latex protection, is inserted into the vagina. Here it emits sound waves that, bouncing off the tissues, return impulses that are then processed by the instrument into images. Transvaginal ultrasound is useful for analyzing the organs of the female genital system and the presence of issues such as ovarian cysts, fibroids, uterine malformations, and tumors. It is a minimally invasive but very effective examination.

In the area dedicated to diagnostic imaging at MiniHospital “Sandro Pertini,” transvaginal ultrasound is performed using a Philips Affiniti 50 ultrasound machine, which allows for ultrasounds and echo color Doppler ensuring speed of execution and maximum accuracy of results.

Transvaginal ultrasound in pregnancy

Transvaginal ultrasound is also used in various stages of pregnancy, but for different purposes. In the first trimester, this examination is used to see the embryo more precisely than with a transabdominal ultrasound. In subsequent trimesters, transvaginal ultrasound is used to check the health of the uterine cervix. In any case, this examination poses no risk to the fetus, as ultrasound is harmless.

How transvaginal ultrasounds are performed

During transvaginal ultrasounds, the patient can lie supine on the gynecological examination table. It is not a painful examination and is performed without anesthesia. During the analysis, the patient can also see the images reproduced on the monitor and follow the process together with the doctor. Transvaginal ultrasounds do not require any particular preparation: patients are only recommended to have an empty bladder to facilitate maneuvers and visualization of the organs. Once the examination is finished, patients can immediately resume their daily activities in complete tranquility.


  • It is advisable to bring any ultrasounds previously performed on the same body area.
  • It is advisable to bring any specialist visits performed.

The advantages of transvaginal examination

Compared to an abdominal or pelvic ultrasound, the transvaginal examination provides images with greater detail and precision. External examinations, in fact, can be hindered by both the more superficial organs and any fatty layers that compromise the accuracy of the ultrasound. Transvaginal examination, on the other hand, allows obtaining anatomical details of the uterus, ovaries, and endometrium not visible with other methods. However, this type of examination is often associated with other examinations to have a more complete picture of the anatomical area.
