About this test
A whole abdomen ultrasound uses sound waves to look at the liver, gall bladder, bile ducts, pancreas, spleen, kidneys, urinary bladder, and the uterus and ovaries in women or the prostate in men. It involves no radiation and no injection.
When is it advised?
- Pain in the abdomen, bloating or indigestion
- Suspected gall bladder stones or kidney stones
- Fatty liver, raised liver enzymes or jaundice
- Burning or frequent urination, or blood in the urine
- Routine health check-up or follow-up of a known condition
How to prepare
- Do not eat for 4–8 hours before the scan so the gall bladder can be seen clearly; an overnight fast with a morning scan is best. Keep the last meal before the fast light and low in fat. Plain water is fine.
- Arrive with a moderately full bladder: drink 3–4 glasses of water about an hour before, and do not pass urine.
- Take your usual medicines unless your doctor says otherwise.
On the day
- A female staff member (chaperone) is always present during the scan.
- Bring your doctor's prescription or referral slip, a photo ID and any previous reports.
- Most scans take about 10–20 minutes on the table.
- The report is prepared by the radiologist, handed to you and also shared on WhatsApp.
Frequently asked questions
Is fasting necessary for a whole abdomen ultrasound?
Yes. Fast for 4–8 hours (overnight is best) so the gall bladder and pancreas show clearly, and keep the last meal before the fast light and low in fat. Water is allowed.
Why do I need a full bladder?
A full bladder lifts the bowel out of the way and lets the bladder, uterus or prostate be seen properly.
Can a whole abdomen ultrasound show kidney stones?
Yes, ultrasound shows most kidney stones and any swelling of the kidney they cause. Very small stones in the ureter can be missed, and your doctor may then advise a CT scan.
