Internal Pelvic Ultrasound

What is an Internal Pelvic Ultrasound?

An internal pelvic ultrasound (also called transvaginal or transabdominal pelvic scan) is a non‑invasive imaging test that uses sound waves to create pictures of the organs inside the pelvis – uterus, ovaries, bladder, and surrounding tissues.

Key Parameters

Why It Is Done

• Routine check‑up for women of reproductive age
• Investigate pelvic pain, abnormal bleeding, or infertility
• Monitor known conditions such as fibroids, ovarian cysts, or endometriosis
• Evaluate early pregnancy or confirm viability
• Assess bladder or kidney issues when symptoms are present

Early Detection

This test can help identify signs of uterine fibroids, ovarian cysts, endometriosis, ectopic pregnancy, or bladder dysfunction, but it does not diagnose these conditions on its own. A clinician interprets the images together with symptoms, history, and other investigations.

What Abnormal Results May Mean

• Enlarged uterus or thickened endometrium could suggest fibroids, polyps, or hormonal changes.
• Ovarian cysts may be functional, benign, or malignant; further tests are needed.
• Fluid collections might indicate infection, bleeding, or other pathology.

Many factors – hydration, recent meals, medications, or menstrual cycle phase – can influence appearance, so results are considered in context.

Who Might Be Advised to Get This Test

• Women experiencing pelvic pain, heavy or irregular bleeding, or fertility issues
• Pregnant women needing confirmation of intra‑uterine pregnancy
• Patients with known pelvic masses or suspected endometriosis
• Individuals with urinary symptoms or bladder dysfunction

Summary

An internal pelvic ultrasound safely visualises pelvic organs, helping doctors spot structural problems and guide further care.

Preparation

• Fasting: No fasting required for a pelvic ultrasound.
• If combined with fasting tests (e.g., blood work), follow the longest fasting period required (usually 8–12 hours).
• Procedure: A gel is applied to the abdomen or vaginal area. A transabdominal probe or a small probe is inserted into the vagina. The scan takes about 15–30 minutes.
• Comfort: The test is painless; you may feel a mild pressure or vibration. No needles or blood draws are involved.
• Precautions: No special medication timing or hydration instructions are needed. Avoid heavy exercise or alcohol 24 hours before if you have other related tests.
• Note: Confirm specific preparation with your doctor or the lab. This information is educational and not a substitute for professional medical advice.
