Transvaginal ultrasound

Gynecologist in London

Transvaginal defines “through the vagina.” It is an internal examination. It uses high-frequency sound waves to create images of internal organs to examine female reproductive organs and also used to identify the abnormalities. Transvaginal ultrasound is called endovaginal ultrasound. 

Transvaginal ultrasound detects uterine gestational sac 1-week earlier than the transabdominal probe and gives a more precise image because of its proximity to the pelvic organs.  The pregnancy and other gynae issues can be detected by Transvaginal ultrasound. Pulsed Doppler ultrasound can add further information regarding the vascularity of the peri trophoblastic structure and reduce the false-positive findings. The transvaginal ultrasound can also detect uterine pregnancy. 

When is a transvaginal ultrasound performed?

  • To check for cysts.
  • Pelvic pain. 
  • Vaginal bleeding.
  • Abnormal pelvic or abdominal exam. 
  • Ectopic pregnancy. 
  • To verify IUD is adequately placed. 
  • Through Transvaginal ultrasound, fetus heartbeat can be monitored.
  • To observe cervix changes which may lead to complications like miscarriage or premature delivery.

Preparation for transvaginal ultrasound: 

  • For the clear picture of pelvic organs, the bladder must not be empty; it must be full.
  • Drink 35 ounces of water or any intake of liquids before an hour. 
  • Remove tampons if you are on the menstrual cycle.

 During a transvaginal ultrasound:

  • The ultrasound wand is bound up with a lubricating gel and condom and is inserted in the vagina.
  • Latex-free probe cover is used in case of any latex allergy.
  • As the doctor inserts the transducer, the patient might feel the pressure. 
  • Once after the insertion of the transducer sound waves bounce off internal organs to transmit pictures of the pelvis.
  • The doctor turns the transducer in the vagina for an extensive picture of organs.
  • The doctors use a saline infusion sonography. They may insert saltwater into the uterus before the ultrasound to identify the abnormalities.
  • Transvaginal ultrasound can be performed on a pregnant woman also.
