What happens during the test?

The device used during transvaginal ultrasound is a probe which is also known as transducer. It emits sound waves that reflect from your internal reproductive organs, which are then received by the computer to produce clear images.

The probe is lubricated with a gel and covered with a condom. It’s then inserted through the vagina and moved to the proximity of the pelvic organs to diagnose the underlying cause.

You may need to change positions during the test and make sure you breathe normally

The doctor may perform another type of transvaginal ultrasound method called saline infusion sonography (SIS) in which a small volume of salt solution is inserted in the uterus to get a better view It’s also called sonohysterography or hysterosonography. SIS is not performed on pregnant women and you do not need to fill your bladder before the test.

The test takes 30-60 minutes for completion

What to expect after the test?

The test is usually painless, though some women may sense certain degree of discomfort and pressure when the device is inserted.

The results are produced immediately. The radiologist or the technician might discuss the reports with your doctor and then reveal it to you. Your doctor will explain you the reports and based on that he will suggest the treatment and further tests if needed.

You should be able to resume your daily chores the next day. There are no health hazards reported except for mild cramping or spotting for a few days.

Transvaginal ultrasound is absolutely safe on health since no radiation is involved. However, make sure you clarify all your doubts with your doctor and listen to his advice for the betterment of your health.
