Details about Kidney, Ureter and Bladder (KUB) Ultrasound
What is a Kidney, Ureter and Bladder (KUB) Ultrasound?
A Kidney, Ureter and Bladder (KUB) ultrasound is a diagnostic imaging scan used to evaluate the urinary tract, including the kidneys, ureters and bladder. Ultrasound uses high-frequency sound waves to create real-time images of these organs without radiation.
The scan allows clinicians to assess the structure, size, and condition of the kidneys, identify abnormalities in the urinary system and evaluate how well urine flows through the urinary tract.
KUB ultrasound is widely used because it is safe, painless, and highly effective for detecting urinary tract problems such as kidney stones, urinary obstruction and bladder abnormalities.
Why do I need a KUB Ultrasound?
A KUB ultrasound may be recommended when symptoms suggest problems affecting the kidneys or urinary system. It can help identify structural abnormalities, stones or signs of urinary blockage.
You may benefit from this scan if you experience:
- Lower back or flank pain
- Blood in the urine (haematuria)
- Pain or burning during urination
- Frequent urination or urgency
- Difficulty emptying the bladder
- Recurrent urinary tract infections
- Suspected kidney stones
- Abnormal kidney function blood tests
- Swelling or fluid retention
- Monitoring of known kidney or bladder conditions
This scan is also commonly used to monitor kidney health and investigate unexplained urinary symptoms.

Follow these guidelines for accurate results
Sample Timing
Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting & Hydration
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Medications & Supplements
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
Hormones & Menstrual Cycle
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
