Detect kidney and bladder stones
Ultrasound can identify stones in the kidneys, ureters (indirectly), and bladder – often the cause of flank pain and urinary symptoms.
KUB ultrasound (Kidneys, Ureters, Bladder) is a focused imaging examination that evaluates the urinary system. It is one of the most commonly requested ultrasound examinations, particularly for patients with flank pain, urinary symptoms, or suspected kidney stones. It provides detailed information about the kidneys (size, structure, and stones), the ureters (indirectly, through signs of obstruction), and the bladder (wall, stones, and residual volume).
This examination is non‑invasive, radiation‑free, and provides real‑time images that help diagnose conditions such as renal stones (nephrolithiasis), hydronephrosis (kidney swelling), urinary tract infections, bladder stones, and masses. It is often the first-line imaging test for patients with suspected urinary tract pathology.
At Amytri, our KUB ultrasounds are performed by experienced consultant radiologists using state‑of‑the‑art equipment. We follow a systematic protocol to ensure a thorough evaluation of the kidneys, ureters, and bladder, and we provide a detailed, actionable report. Our goal is to give you and your doctor the information needed for accurate diagnosis and effective treatment.
Kidney stones and urinary tract conditions are common – and often painful. KUB ultrasound provides a rapid, accurate, and radiation‑free assessment to identify the cause.
Ultrasound can identify stones in the kidneys, ureters (indirectly), and bladder – often the cause of flank pain and urinary symptoms.
Ultrasound assesses kidney size, cortical thickness, and the presence of cysts or masses – essential for evaluating renal function and disease.
Hydronephrosis (kidney swelling) is a key sign of urinary tract obstruction – ultrasound can detect it early, guiding timely intervention.
We examine each component of the urinary system systematically, using a standardised protocol.
We assess kidney size, echogenicity, and cortical thickness. We detect stones (nephrolithiasis), cysts, masses, and hydronephrosis (dilatation of the collecting system).
If hydronephrosis is present, we grade its severity (mild, moderate, or severe) – helping determine the urgency of further evaluation and intervention.
While ureters are not directly visible in healthy individuals, we assess for signs of obstruction – such as hydronephrosis or the presence of a stone at the ureterovesical junction.
We assess bladder wall thickness, the presence of stones, diverticula, or masses. We also measure residual urine volume if clinically indicated.
If indicated, we perform Doppler assessment of renal vessels to evaluate renal blood flow and identify renal artery stenosis.
We assess the adrenal glands (if visible) for any masses or enlargement.
We ask you to drink water and have a comfortably full bladder before the scan – this distends the bladder and provides a clear window for imaging. Fasting is not required.
You lie on your back (and sometimes on your side) on the examination table. The radiologist applies gel to your abdomen and scans the kidneys, ureters, and bladder. You may be asked to hold your breath or turn to your side.
The radiologist reviews the images and provides a comprehensive report, noting any abnormalities, measurements, and conclusions. The report is shared with your referring doctor.
We discuss the findings with you (where appropriate) and recommend further steps – which may include additional imaging, laboratory tests (urinalysis, renal function), or specialist referral (urology).
It is a key investigation for a wide range of urinary tract symptoms and conditions.
Severe, sharp pain in the side or back – often indicative of kidney stones – requires urgent ultrasound evaluation.
Blood in urine, painful urination, or frequent urination may indicate stones, infection, or bladder pathology.
Patients with a history of stones benefit from regular ultrasound surveillance to monitor for recurrence.
Elevated creatinine or urea may indicate kidney disease – ultrasound assesses kidney size, structure, and hydronephrosis.
Recurrent UTIs may be associated with stones, anatomical abnormalities, or incomplete bladder emptying – ultrasound can identify these.
KUB ultrasound is often included in full body health check‑ups to screen for silent kidney conditions.
Dr. Abhishek has extensive experience in renal and urinary tract ultrasound, with a special focus on detecting stones, hydronephrosis, and bladder pathology. He is skilled in performing comprehensive KUB examinations and interpreting subtle findings that guide accurate diagnosis and effective treatment.
If you are coming for a health check‑up or feel anxious about the results, having your partner with you can provide reassurance.
We welcome partners to attend the ultrasound. We explain what we are seeing, show you the images on screen, and discuss the findings. Your partner's presence can be helpful for understanding the results and planning next steps together.
KUB ultrasound is a focused imaging examination that evaluates the Kidneys, Ureters, and Urinary Bladder. It is used to detect kidney stones, hydronephrosis, bladder pathology, and other urinary system conditions.
Yes, we ask you to drink water and have a comfortably full bladder before the scan. This distends the bladder and provides a clear window for imaging. We will give you specific instructions when you book.
No, fasting is not required for a KUB ultrasound. You can eat and drink normally before the scan.
No, the scan is painless. You may feel mild pressure from the transducer as it moves over your abdomen, but it is not uncomfortable.
Ultrasound is good at detecting stones in the kidneys and bladder. However, very small stones (especially in the ureters) may not be visible, and CT may be required for smaller stones. Ultrasound is the first‑line test due to its safety and accessibility.
Yes, a referral from your doctor is recommended. They will use the results to guide your diagnosis and treatment. You can also book directly for a routine health check‑up.
