Transvaginal ultrasound is an examination of the female pelvis and urogenital tract (kidneys and bladder). It helps to see if there is any abnormality in your uterus (womb), cervix (the neck of the womb), endometrium (lining of the womb), fallopian tubes, ovaries, bladder and the pelvic cavity. It differs from an abdominal ultrasound as it looks at the pelvic organs from inside the vagina.
The test is requested by your doctor if you have symptoms of pelvic pain, abnormal bleeding, to check for fibroids (muscle tumours of the uterus), polyps (areas of thickening of the lining of the uterus), ovarian cysts or tumours, infertility, or assessment of early pregnancy.
Transvaginal ultrasound. The transducer is shaped to fit into a woman’s vagina. A woman may have both transabdominal and transvaginal ultrasounds to look at the whole pelvic area. A transvaginal ultrasound is done to look for problems with fertility or pregnancy. In rare cases, a hysterosonogram is done to look at the inside of the uterus by filling the uterus with fluid during a transvaginal ultrasound. Sometimes, a small sample of tissue (biopsy) may be taken with small tools inserted through the vagina during a transvaginal ultrasound.
In all three types of pelvic ultrasound, the transducer sends the reflected sound waves to a computer, which makes them into a picture that is shown on a video screen. Ultrasound pictures or videos may be saved as a permanent record.
What are the benefits of a transvaginal ultrasound?
The insertion of the transducer into the vagina allows a very close and clear view of the pelvic organs and very clear ultrasound images to be taken of the area. This will help to guide the discussion between you and your doctor about any further investigation or treatment that may be needed.
