KUB Ultrasound — About the Test

A KUB Ultrasound (Kidney, Ureter, Bladder Ultrasound) is a real-time imaging scan of the urinary tract — using high-frequency sound waves to create detailed images of the kidneys, ureters, and bladder without any radiation. It is the first-line investigation for kidney stones, flank pain, blood in urine (haematuria), urinary tract infections, and kidney swelling. In a single scan of 15–20 minutes, it can assess the size, shape, and structure of both kidneys, detect stones anywhere in the urinary tract, and evaluate the bladder for abnormalities. No radiation. No injections. Completely safe. Important preparation: A full bladder is required for the bladder portion of the scan. Drink 4–6 glasses of water 1 hour before your appointment and do not urinate until after the scan.

What Happens During a KUB Ultrasound? (15–20 Minutes)

Key benefits of this package include:

Step 1 — Preparation: Drink 4–6 glasses of water approximately 1 hour before your scan and do not urinate. A full bladder is essential for clear bladder imaging. You may be asked to fast for 4–6 hours if gallbladder or upper abdomen structures are also being assessed.
Step 2 — Before the scan: You will lie on the scanning table. You may need to partially lift or lower your clothing to expose the abdomen and flank areas. No gown is usually required.
Step 3 — The scan: The sonographer applies a cool, water-based gel to your skin — this helps the ultrasound probe (transducer) glide smoothly and improves sound transmission. The probe is pressed gently against your skin while the sonographer takes images of both kidneys from multiple angles, then the bladder.
Step 4 — Post-void scan (if needed): For the bladder, the sonographer may ask you to urinate after the initial scan and will then rescan to measure residual urine volume — important for detecting incomplete bladder emptying.
Step 5 — Done: The entire scan takes 15–20 minutes. The gel wipes off easily. Your sonologist report is ready within 4 hours.

What a KUB Ultrasound Can Detect

Kidneys

Kidney stones (renal calculi) — echogenic foci with posterior acoustic shadowing

Hydronephrosis — swelling of the kidney from urinary outflow obstruction

Renal cysts — simple or complex fluid-filled structures within the kidney

Renal tumours — solid masses requiring further evaluation with CT or MRI

Kidney size and cortical thickness — indicators of chronic kidney disease (CKD)

Renal vascular abnormalities — when combined with Doppler imaging

Pyelonephritis — increased echogenicity and kidney swelling from infection

Polycystic kidney disease — multiple cysts throughout both kidneys

Ureters

Ureteric stones — most visible at ureterovesical junction (where ureter meets bladder)

Ureteric dilatation — widening of the ureter indicating downstream obstruction

Hydro-ureter — ureter distension from obstruction

Bladder

Bladder stones — echogenic foci that shift with position change

Bladder wall thickening — from chronic infection, outflow obstruction, or tumour

Bladder tumours — intraluminal masses

Bladder diverticula — outpouching of the bladder wall

Post-void residual volume — measures how completely the bladder empties

Enlarged prostate impression — in men, indentation of bladder base from BPH

FAQs

A KUB Ultrasound scans the kidneys, ureters, and bladder to detect kidney stones, cysts, tumours, hydronephrosis, bladder wall abnormalities, and urinary tract issues. It is the first-line imaging investigation for flank pain, blood in urine, recurrent UTIs, and kidney function concerns.

Yes — this is the most important preparation step. Drink 4–6 glasses of water approximately 1 hour before your appointment and do not urinate until after the scan. A full bladder is essential for clear imaging of the bladder and lower ureters.

Fasting is not strictly required for a KUB scan. However, if your doctor has also requested an abdominal ultrasound (liver, gallbladder) in the same session, 4–6 hours of fasting is required for clear gallbladder imaging. Your Medall team will advise.

Yes. Ultrasound uses sound waves — not radiation. It is completely safe for all ages, including during pregnancy.

Ultrasound detects most kidney and bladder stones well. However, mid-ureteric stones (between the kidney and bladder) can be difficult to see on ultrasound due to overlying bowel gas. A CT KUB (non-contrast CT) is the most sensitive test for detecting all urinary tract stones.

15–20 minutes. Report ready within 4 hours.
