Ultrasound Lower Abdomen

A lower abdominal (pelvic) ultrasound visualizes the bladder, uterus, ovaries, fallopian tubes (when visible), prostate in men, nearby pelvic organs and blood flow. It detects pregnancy and fetal heartbeat, cysts, fibroids, pelvic masses, fluid collection, abscesses, urinary retention and some stones. Doppler can assess blood flow. It’s noninvasive and commonly used for pain, abnormal bleeding, infection or infertility.

Drink 1–1.5 litres (about 32–50 oz) of water one hour before the scan and avoid urinating so your bladder is full for a transabdominal lower abdominal/pelvic ultrasound. For a transvaginal scan you’ll be asked to empty your bladder. Wear loose, two‑piece clothing, bring prior imaging/reports, and follow any clinic-specific fasting or medication instructions. Arrive early and tell staff about pregnancy or allergies.

Pelvic ultrasound can detect pregnancy-related conditions (intrauterine pregnancy, ectopic pregnancy, miscarriage), uterine problems (fibroids, polyps, adenomyosis, congenital anomalies), endometrial thickening or suspected cancer, ovarian disorders (cysts, tumors, endometriomas, torsion), pelvic inflammatory disease/tubo-ovarian abscess, hydrosalpinx, pelvic masses and pelvic fluid (hemoperitoneum or ascites). It guides diagnosis and may need follow-up tests.

For a lower‑abdominal (pelvic) ultrasound you are usually asked to drink water and keep a full bladder. Typically patients drink about 500–1000 mL (≈2–4 cups) about an hour before the scan and avoid urinating, because a full bladder lifts bowel gas and provides an acoustic window to see the uterus, ovaries and bladder. For transvaginal scans, an empty bladder is often preferred.

Costs vary by country and setting. In the US, a lower‑abdominal (pelvic) ultrasound typically costs about $100–$1,000 out‑of‑pocket, often $200–$500 after insurance. In the UK it’s free on the public system but private scans run roughly £80–£250. In India, routine ultrasounds commonly range ₹500–₹2,500. Exact price depends on facility, scan type, and specialist reporting.

Pelvic ultrasound is usually not painful. An abdominal scan may cause pressure or discomfort from a full bladder. A transvaginal scan can feel like pressure or mild cramping when the probe is inserted, but most people tolerate it well. If you experience significant pain, bleeding, or severe discomfort, tell the clinician so they can stop and assess.
