NCCT KUB (Non-Contrast CT KUB) is performed without intravenous contrast injection. It is the definitive first-line investigation for suspected ureteric colic (kidney stones) — detecting stones of all compositions (including uric acid stones invisible on plain X-ray) with sensitivity exceeding 97% and specificity above 96%. The absence of contrast eliminates reaction risk and makes it safe for patients with renal impairment.
CECT KUB (Contrast-Enhanced CT KUB) is performed with intravenous iodinated contrast, allowing evaluation of the renal parenchyma, urothelium, and vascular supply. It is superior for detecting renal masses, transitional cell carcinoma of the ureter/renal pelvis, renal vein thrombosis, and characterising complex renal cysts. Triple-phase imaging (pre-contrast, nephrographic, and excretory phases) constitutes CT Urography.
Why is a KUB CT Scan Done?
- Renal and ureteric calculi (kidney stones): The primary indication for NCCT KUB — detects stones as small as 1 mm anywhere in the urinary tract, assesses size, location, and degree of obstruction.
- Ureteric colic: Acute flank pain radiating to the groin with haematuria — classic presentation requiring urgent NCCT KUB.
- Haematuria investigation: Both macro and microscopic haematuria require imaging to exclude urinary tract tumours, stones, and structural abnormalities.
- Renal mass characterisation: CECT KUB/CT Urography evaluates incidentally detected or symptomatic renal masses — distinguishing benign cysts from solid tumours.
- Suspected hydronephrosis: Identifies the level and cause of urinary obstruction causing kidney swelling.
- Urinary tract infection (UTI) complications: Detects pyelonephritis, renal/perirenal abscess, emphysematous pyelonephritis, or pyonephrosis in severe or recurrent UTI.
- Renal trauma: Assesses kidney laceration, contusion, vascular injury, or urinoma after abdominal trauma.
- Post-operative surveillance: Follow-up after renal surgery, ureteroscopy, or percutaneous nephrolithotomy (PCNL).
Symptoms That Require a KUB CT Scan
- Sudden severe flank pain (loin-to-groin pain) — classic ureteric colic
- Blood in urine (haematuria) — visible red/pink urine or detected on dipstick
- Difficulty or pain on urination with fever and flank tenderness (pyelonephritis)
- Recurrent urinary tract infections not responding to antibiotics
- Swelling or lump felt in the abdomen or flank
- Unexplained weight loss combined with haematuria (possible urothelial malignancy)
- Incomplete bladder emptying and urinary retention
- Nausea and vomiting associated with flank pain
Who Should Get a KUB CT Scan?
- Patients with suspected kidney stones — especially first-time colic or stones not seen on plain X-ray
- Anyone with unexplained haematuria requiring urological investigation
- Patients with recurrent UTI requiring structural assessment of the urinary tract
- Patients referred by nephrologists, urologists, or emergency physicians for urinary tract evaluation
- Pre-operative planning before ureteroscopy, PCNL, or renal surgery
- Post-operative follow-up after urological procedures
- Patients with known renal cysts requiring characterisation or surveillance
Preparation Before a KUB CT Scan
Preparation requirements differ between NCCT and CECT KUB:
For NCCT KUB (No Contrast)
- No fasting required — you can eat and drink normally.
- A moderately full bladder improves bladder visualisation — drink 2–3 glasses of water 30 minutes before the scan if possible.
- Remove all metal objects from the abdomen and pelvis area.
- Inform staff of pregnancy.
For CECT KUB (With Contrast)
- Fast for 4–6 hours before the scan (water is permitted).
- Blood urea and serum creatinine test required — renal function must be adequate before contrast injection.
- Metformin must be stopped 48 hours before and resumed 48 hours after contrast administration.
- Inform team of any previous contrast allergy — pre-medication with antihistamine and steroid may be arranged.
- An intravenous cannula will be placed in the arm for contrast injection.
Step-by-Step KUB CT Procedure
- Registration and safety check: Complete patient registration and a safety and allergy questionnaire.
- Cannula placement (CECT only): An intravenous cannula is inserted in the antecubital vein for contrast injection.
- Positioning: You lie on your back (supine) on the CT table with arms either above the head or alongside the body.
- Scout image: A brief digital topogram from diaphragm to pubic symphysis is acquired to plan the scan range.
- Pre-contrast scan (NCCT KUB): The CT acquisition covers the entire urinary tract from kidneys to bladder base. This phase detects stones of all compositions with maximum sensitivity.
- Contrast injection and phase imaging (CECT KUB): Iodinated contrast (approximately 80–100 mL) is injected at a controlled rate. Images are acquired in the corticomedullary, nephrographic, and excretory phases to evaluate renal parenchyma, collecting system, ureters, and bladder.
- Delayed imaging: For CT Urography, delayed images at 5–15 minutes show contrast-filled ureters and bladder — evaluating the urothelium for filling defects, strictures, or tumours.
- Image reconstruction: Multiplanar reconstructions (MPR) in coronal, sagittal, and 3D planes are generated to map the entire urinary tract.
- Scan completion: The table retracts and the scan is complete. The cannula is removed (CECT).
- Reporting: A detailed structured report covering both kidneys, ureters, bladder, and relevant adjacent anatomy is prepared by our uroradiologist.
How Long Does a KUB CT Scan Take?
An NCCT KUB takes approximately 10–15 minutes total. A CECT KUB or CT Urography takes 30–45 minutes due to the requirement for multiple timed post-contrast phases and delayed imaging. The actual scan acquisition time for each phase is 10–20 seconds.
Is the KUB CT Scan Safe?
NCCT KUB is very safe — no contrast is given, making it appropriate for all patients including those with renal impairment. CECT KUB carries the standard risks associated with iodinated contrast agents (allergy, nephropathy), which are minimised through pre-screening and hydration protocols at Edge Imaging & Diagnostics. The radiation dose for a KUB CT (approximately 3–5 mSv) is considered moderate and is justified by the clinical benefit.
Risks and Complications of KUB CT Scan
- Radiation dose: 3–5 mSv effective dose — equivalent to 1–1.5 years of background radiation. Justified for appropriate clinical indications.
- Contrast reaction (CECT only): Minor reactions (nausea, flushing, urticaria) in 1–3% of patients. Severe anaphylaxis is very rare (<0.1%). Managed immediately by our trained team.
- Contrast nephropathy (CECT only): Temporary worsening of kidney function in patients with pre-existing renal impairment. Prevented by hydration protocols and renal function screening.
- Extravasation: Contrast leaking into surrounding tissue at the cannula site — usually minor and resolves without treatment.
Benefits of KUB CT Scan
- Gold standard for kidney stone detection — superior to ultrasound and plain X-ray
- Detects ALL stone compositions including radiolucent uric acid stones
- Assesses stone size, location, and degree of hydronephrosis — guiding treatment planning
- Evaluates entire urinary tract in one examination
- CECT phases provide comprehensive renal parenchymal and urothelial assessment
- Results available same day for urgent clinical decisions
- Guides urological intervention — ureteroscopy, PCNL, stent placement
Accuracy of KUB CT Scan
NCCT KUB has a sensitivity of 95–98% and specificity of 96–98% for urinary tract calculi — significantly superior to ultrasound (sensitivity ~78%) and plain X-ray KUB (sensitivity ~58%). It detects stones as small as 1 mm and determines their exact location, size, and the degree of proximal urinary tract dilatation. CECT KUB achieves sensitivity above 90% for renal cell carcinoma characterisation and over 85% for transitional cell carcinoma detection. At Edge Imaging & Diagnostics in Paschim Vihar, Delhi, our experienced uroradiologists maximise diagnostic accuracy using optimised scan protocols and multiplanar image reconstruction.

Frequently Asked Questions About KUB CT Scan
1. What is an NCCT KUB scan?
NCCT KUB is a non-contrast CT examination of the kidneys, ureters, and bladder. It is the gold-standard investigation for kidney stones, detecting all stone types including radiolucent uric acid stones with sensitivity exceeding 97%. No injection is required.
2. Is a KUB CT scan painful?
An NCCT KUB is completely painless — no injections, no needles. For CECT KUB, a brief cannula insertion for contrast injection may cause mild discomfort. Some patients experience a warm flushing sensation during contrast injection, which resolves quickly.
3. How long does a KUB CT scan take?
An NCCT KUB takes approximately 10–15 minutes total. A CECT KUB or CT Urography takes 30–45 minutes due to multiple timed contrast phases. The actual scan acquisition for each phase takes only 10–20 seconds.
4. What is the difference between NCCT KUB and CECT KUB?
NCCT KUB is without contrast — ideal for kidney stone detection, safe for all patients including those with renal impairment. CECT KUB uses intravenous contrast to evaluate renal parenchyma, urothelium, and vasculature — better for renal tumours, transitional cell carcinoma, and vascular conditions.
5. Do I need to fast before a KUB CT scan?
No fasting is needed for NCCT KUB. For CECT KUB, fasting for 4–6 hours (water permitted) is recommended before contrast injection. A bladder moderately full of urine improves visualisation of the distal ureter and bladder.
6. Can NCCT KUB detect all types of kidney stones?
Yes. NCCT KUB detects virtually all urinary tract stone compositions — calcium oxalate, calcium phosphate, uric acid, struvite, and cystine stones — including those invisible on plain X-ray KUB. Only very rare stones (some drug-related stones) may occasionally be missed.
7. What is the radiation dose of a KUB CT scan?
An NCCT KUB delivers an effective radiation dose of approximately 3–5 mSv — equivalent to about 1–1.5 years of natural background radiation. This is considered moderate and is justified by the high diagnostic value of the investigation for kidney stone and urinary tract disease.
8. Is NCCT KUB better than ultrasound for kidney stones?
Yes. NCCT KUB has a sensitivity of 95–98% for kidney stones compared to approximately 78% for ultrasound. CT is superior for detecting small stones (<5 mm), mid-ureteric stones (often hidden by bowel gas on ultrasound), and assessing degree of obstruction. Ultrasound remains useful as a radiation-free screening tool.
9. Can I take my regular medications before a KUB CT?
Yes for most medications. However, metformin (for diabetes) must be stopped 48 hours before a CECT KUB and resumed only 48 hours after, to reduce the risk of contrast-induced lactic acidosis. Always inform our team of all medications you are taking.
10. What does a KUB CT report contain?
A KUB CT report includes assessment of both kidneys (size, parenchymal thickness, calculi, masses, cysts), ureters (course, calibre, stones, strictures), bladder (wall thickness, filling defects, calculi), and adjacent organs. Stone measurements, Hounsfield unit density, and degree of hydronephrosis are specifically reported to guide urological management.
11. How do I book a KUB CT scan in Delhi?
Book your NCCT KUB or CECT KUB scan at Edge Imaging & Diagnostics in Paschim Vihar, West Delhi by calling our centre or visiting edgeimaging.in. Emergency KUB scans for acute ureteric colic are accommodated on priority. Bring your referral letter and previous ultrasound reports.
12. Can NCCT KUB diagnose causes of haematuria other than stones?
NCCT KUB can identify some causes of haematuria such as stones, renal vascular malformations, and papillary necrosis. However, for comprehensive haematuria evaluation including tumour detection, CECT KUB or CT Urography with contrast phases is recommended as it provides superior urothelial assessment.
