What is a transvaginal ultrasound, and when is it required?
Written by:Transvaginal ultrasound scanning is the latest topic of discussion in one of our latest informative medical articles.
Here, Mrs Sajitha Parveen, distinguished consultant obstetrician and gynaecologist, details what a transvaginal ultrasound is, and outlines the main differences between a general ultrasound scan and a transvaginal ultrasound.
What is a transvaginal ultrasound, and how does it differ from a general ultrasound scan?
A transvaginal ultrasound is an imaging procedure performed in order to examine the female pelvis. An ultrasound probe is inserted into the vagina to visualise the pelvic organs, which are the uterus, cervix, tubes, ovaries, and pelvic area.
A transabdominal ultrasound is performed by placing the transducer on the abdomen to visualise the pelvic organs.
When is a transvaginal ultrasound required?
A transvaginal ultrasound is required when the patient and specialist want to get more detailed images of the pelvic organs. A transvaginal scan is capable of providing greater detail of the pelvic organs, and can easily and effectively identify the pathology.
It is commonly used to assess uterine fibroids; polyps; ovarian cysts; early pregnancy; miscarriage; ectopic pregnancy; missing coil; fertility issues; abnormal vaginal bleeding. It is very helpful when monitoring very early pregnancy in cases where an abdominal ultrasound wouldn’t be adequate.
Who is the ideal candidate for it?
If a woman has been pregnant for less than eight weeks, a vaginal ultrasound may be needed for clearer images. The bladder should be empty, allowing the uterus to remain lower in the pelvis and closer to the vaginal probe.
Women with a higher BMI may see images that are not as clear, and therefore women with a high BMI may benefit from a transvaginal scan. The majority of sexually active women are suitable for a transvaginal scan. Transvaginal ultrasound scans are indicated to measure the thickness of the lining of the womb.
Are there any related complications?
There are no known risks associated with the procedure, and no complications after the scan have been reported. Both the pregnant woman and the foetus are safe, due to the fact that no radiation is used in this imaging technique.
When the transducer is inserted into the woman’s vagina, they will feel pressure and, in some cases, a little discomfort. However, this discomfort should be minimal and should go away once the procedure is complete. If something is extremely uncomfortable during the exam, the patient should let the doctor or technician know.
How long does a transvaginal ultrasound take?
It is a very quick procedure and usually takes between 15 to 30 minutes to perform.
