What Is Transvaginal Ultrasound?
Transvaginal ultrasound (TVUS) is an imaging procedure that uses high-frequency sound waves to create detailed images of the uterus, ovaries, fallopian tubes, cervix, and pelvic structures. The ultrasound probe is inserted into the vagina to provide a closer and clearer view compared to abdominal ultrasound.

When Is This Procedure Needed?
TVUS may be recommended for:

  • Evaluating pelvic pain or abnormal bleeding.
  • Diagnosing ovarian cysts, fibroids, or endometrial abnormalities.
  • Assessing early pregnancy or suspected miscarriage.
  • Monitoring follicle growth during fertility treatments.
  • Detecting possible ectopic pregnancy.

Procedure Overview

  1. Preparation – Usually no special preparation is needed; bladder should be empty for comfort.
  2. Probe Placement – A covered, lubricated ultrasound probe is gently inserted into the vagina.
  3. Image Capture – The probe emits sound waves to generate real-time images of the pelvic organs.
  4. Assessment – The doctor evaluates the size, shape, and condition of the uterus, ovaries, and surrounding structures.

Benefits

  • Provides high-resolution images of pelvic organs.
  • Non-invasive and does not use radiation.
  • Quick (usually 15–30 minutes) and safe for most patients.

Risks & Considerations

  • Mild discomfort during insertion of the probe.
  • Not recommended during late pregnancy unless specifically indicated.
  • Very rare risk of infection.
