What is a transvaginal ultrasound? Ultrasound is a basic tool for understanding the state of sexual and reproductive health in women. It is used routinely for diagnosing pathologies or monitoring pregnancies. In this article, we will tell you everything you need to know.

What is a transvaginal ultrasound?

A transvaginal ultrasound is an imaging test performed quickly and with minimal discomfort. It is one of the most common procedures in gynecology. Unlike traditional abdominal ultrasounds, it provides specialists with a detailed view of the pelvic structure. It helps evaluate patient symptoms, diagnose pathologies, monitor pregnancies, or plan surgeries. Ultrasound is fundamental for understanding women’s sexual and reproductive health, whether for routine check-ups, pathology diagnosis, or pregnancy monitoring.

How long does it take?

The procedure typically lasts between 5 and 15 minutes. Generally, it requires minimal time. However, patients with complex pathologies may need a bit more time.

How to prepare for a transvaginal ultrasound?

There is no specific preparation required for this test. Fasting or special preparations are not necessary.

Does a transvaginal ultrasound hurt?

The procedure is quick, virtually painless, and carries little risk of side effects.

What does a transvaginal ultrasound show?

This ultrasound examines the pelvic organs including the cervix, uterus, fallopian tubes, and ovaries. The device is inserted into the vagina to capture images of the pelvic cavity. Using sound waves, it generates images displayed on a screen. Static images, called sonograms, can be examined later.

What can a transvaginal ultrasound detect?

It provides detailed views of pelvic organs and soft tissues compared to abdominal ultrasounds. It detects abnormal structures or growths indicating conditions or diseases. It can also confirm or monitor pregnancy.

Specialists may recommend transvaginal ultrasound to detect problems accompanied by unpleasant symptoms like pelvic pain or abnormal bleeding. Additionally, it can supplement information from a pelvic exam detecting anomalies.

For Detecting Pathologies

• Cysts
• Tumors
• Fibroids
• Polyps
• Signs of pelvic infection
• Signs of oncological pathology
• Signs of ectopic pregnancy or miscarriage
• Possible causes of infertility
• Size, shape, and position of the uterus and ovaries
• Thickness, echogenicity, and presence of fluid or masses in the endometrium, myometrium, fallopian tubes, bladder, or surrounding areas
• Length and thickness of the cervix

In Pregnancy

• Determine gestational age
• Confirm fetal heartbeats
• Identify warning signs of miscarriage or premature labor
• Identify certain conditions that may affect pregnancy progression, such as placenta previa

Can a transvaginal ultrasound cause miscarriage?

There may be concerns that a transvaginal ultrasound during pregnancy could affect the fetus or cause miscarriage. Currently, there is no evidence linking ultrasound to increased miscarriage risk.
