About the Kidney Scan
A Private Kidney Scan (KUB or Renal & Urinary Tract Ultrasound) is a non-invasive, painless diagnostic ultrasound examination designed to evaluate the health of your kidneys, ureters, and urinary bladder.
Using advanced high-frequency sound waves, this scan provides real-time, high-resolution imaging of your renal system without using harmful ionizing radiation or invasive dyes. Performed by our expert HCPC-registered healthcare specialists, a private kidney scan offers instant clinical clarity regarding unexplained flank or lower back pain, recurrent urinary tract infections (UTIs), or suspected kidney stones—all with no GP referral needed.
Objective of the scan
The primary objective of a private renal scan is to thoroughly evaluate the anatomical structure, tissue health, and operational efficiency of your urinary system. Key objectives include:
Structural Assessment: Evaluating the size, shape, position, and internal tissue integrity of both kidneys.
Blockage & Stone Identification: Detecting obstructions, or renal calculi (kidney stones) along the urinary tract.
Bladder Function Checks: If symptomatic measuring pre- and post-void bladder volumes to assess urine retention or incomplete emptying.
Pain & Infection Investigation: Identifying if any underlying causes of persistent flank pain, blood in the urine (haematuria), or frequent UTIs is visible.
Need a broader check of your upper abdomen? Consider our comprehensive Private Abdominal Ultrasound Scan, which evaluates the liver, gallbladder, pancreas, and spleen alongside the kidneys.
Why choose us for your Private Kidney Scan
What brought you here?
Pick the closest match. We'll show what the scan looks for and what usually happens next.
What the scan looks for
Stones in the kidney, swelling of the collecting system from a blockage, and kidney size, outline and tissue appearance.
What happens next
A verbal summary before you leave and a written report within 24 hours for your GP or urology. Marked obstruction with pain and fever is flagged for urgent care.
What the scan looks for
Stones, a mass in the kidney, and the bladder wall and lining for thickening, stones or a visible growth.
What happens next
We explain the findings on the day and send a written report within 24 hours. Blood in the urine is always referred on to urology for full assessment.
What the scan looks for
Structural causes of recurrent infection: obstruction, kidney scarring, bladder stones and how completely your bladder empties.
What happens next
A written report within 24 hours including bladder volumes where measured, for your GP or urology team.
What the scan looks for
Bladder volume before and after you pass urine, bladder wall thickening, and whether pressure has backed up to the kidneys.
What happens next
A verbal overview on the day and a written report within 24 hours with the residual volume, for your GP or urologist.
What the scan looks for
The number, size and internal features of your cysts, and whether any has developed septations or solid areas.
What happens next
A written report within 24 hours with current measurements. Any cyst that no longer looks simple is recommended for further imaging or urology review.
What the scan looks for
Prostate size and outline, bladder wall thickening, and how much urine is left behind after you pass water.
What happens next
A written report within 24 hours with the measurements for your GP or urologist, who read it alongside a PSA blood test.
Please note: Ultrasound often can't see stones sitting part-way down the ureter, and it can't measure how well your kidneys are filtering or confirm whether a mass is cancerous. Blood tests, a CT KUB or MRI are used for those.

How to prepare
Arriving with the right preparation is important as failure to do so may result in us not being able to perform the scan.
Full bladder
- A comfortably full bladder is required for this scan – Please drink 0.5 litres of fluid approximately 30 minutes or so before your scheduled appointment and kindly try your best not to empty your bladder before the examination.
- You may maintain your normal medication regime.
- You can eat as normal.
On the day
During the scan, you will be asked to uncover the area being scanned, hence we advise to wear suitable loose clothing and a small amount of ultrasound gel will be placed over your skin.
An ultrasound camera (‘probe’) will then be placed on top and moved along and around the area. This results in a picture appearing on the ultrasound monitor and patient TV which will be translated by the clinical specialist/ medical practitioner.
The ultrasound scan itself usually lasts around 10-15 minutes and is pain-free. At the end of the scan, a verbal summary of the results will be provided, as well as your opportunity to ask any questions.
Over the tummy
Transabdominal
Warm gel on the lower abdomen and a handheld probe moved across the area. A comfortably full bladder gives the clearest view.
Right after
Your clinician talks you through a verbal summary and answers your questions.
Within 24 hours
A formal written report arrives by email, ready to share with your GP.
If anything needs follow-up
We explain what was seen, the options and who to speak to next.
More about the Kidney Scan
Common Findings Explained
🪨 Kidney Stones (Nephrolithiasis):
Hardened mineral deposits that form inside the kidneys. Ultrasound accurately detects stone location, size, and whether a stone is blocking urine flow along the urinary tract.
💧 Kidney Cysts (Simple & Complex):
Fluid-filled sacs located on or within the kidney tissue. Most cysts are benign (harmless) simple cysts, but ultrasound helps differentiate them from complex cysts that require monitoring.
🌊 Hydronephrosis (Kidney Swelling):
Swelling of one or both kidneys caused by a build-up of urine when a blockage (such as a kidney stone or structural narrowing) prevents normal drainage.
🚽 Bladder Wall Changes & Residual Volume:
Ultrasound assesses bladder wall thickness, checks for polyps or stones, and measures how efficiently your bladder empties after urination.
🧬 Renal Mass or Structural Variation:
Identifies benign tissue growths, structural variations (like a horseshoe kidney), or localized tissue changes that require further clinical review.

Common Questions
How much is a kidney scan in the UK?
The cost of a private kidney ultrasound scan varies wildly but can start from as low as £130. The exact cost you pay will vary depending on the clinic you choose and the type of kidney scan required.
What are the 3 early warning signs of kidney disease?
The three most common early warning signs of kidney disease include swelling in your hands or feet, high blood pressure and protein in your urine. Some people also report having bloody urine and urinary tract infections.
What is the kidney scan looking for?
A kidney scan looks at the size, position and shape of the kidneys and how they are working. It will show if there are any signs of damage to the kidneys or certain abnormalities such as swelling or kidney stones.
How long does a kidney scan take?
The private kidney scan procedure itself typically takes 15-20 minutes and results are commonly given verbally following your scab.
Otherwise, a government facility might take longer because of the long queues you might find at the facility and results will often take much longer.
Can a scan show kidney damage?
A kidney scan might show abnormalities in the size or shape of the kidneys that might suggest kidney damage or disease. However, additional testing and imaging, like a CT scan or MRI scan, might be used to confirm the damage and its extent.
Do you need to drink before a kidney scan?
Yes. You will need to have a full bladder for your kidney scan by drinking a substantial amount of fluid such as water or squash an hour or so before the scan without using the restroom.
Unless advised otherwise by your healthcare provider, you can eat and drink as normal on the day of the test.
