Ultrasound is a modality used for investigating different disorders for planning treatment. Ultrasound consists of waves that pass through the body without harmful effects, resulting in a detailed image of the soft tissues. It is a diagnostic procedure, but it can be used as an adjunct to treatment, called therapeutic ultrasonography. An ultrasound is performed usually by a Radiologist; however, gynecologists may also perform it if needed.
Ultrasound is a safe imaging modality, which can be used to identify disorders in pregnant females. There are different types of ultrasound techniques, and different probes are used for it, one of which is transvaginal ultrasound. It is a minimally invasive method of ultrasound.
Why is Trans Vaginal Ultrasound Needed?
Abdominal ultrasound detects disorders of organs like liver, kidneys, stomach, intestine, pancreas, and spleen. Pelvic ultrasound is used to identify urinary bladder, uterus, fallopian tubes, cervix, prostate and ovaries. Rectal ultrasound is also used to see an image of the above-mentioned pelvic organs.
Transvaginal ultrasound TVS (through the vagina) is mostly required to identify disorders related to uterus, fallopian tubes, and ovaries in detail. Ovaries are deep-seated, and imaging is poor in pelvic ultrasound. It is called transvaginal, because the ultrasound probe is inserted through the vagina up to the cervix, waves pass through the walls of the vagina and the image is obtained showing organs of the pelvis.
After taking informed consent, the patient is asked to lie down and feet are held up in stirrups. Then the transducer is covered with lubricant and/ or latex covering and introduced into the vagina. The procedure does not last long and is not painful. It is avoided in young females to avoid damaging the tissues. It has become a common practice these days in identifying the polycystic ovarian syndrome.
