About The Test
A CT SCAN OF KUB WITH CONTRAST is a painless imaging test that captures detailed 3D pictures of the Kidneys, Ureters, and Bladder (KUB). At Cadabams Diagnostics, we use advanced 128-slice CT scanners to detect stones, infections, or structural issues faster and more precisely than standard X-rays or ultrasound.
What is CT KUB Scan?
A CT KUB Scan uses X-rays and computer processing to create cross-sectional images of the urinary tract. When contrast dye is injected through a vein, the scan is called a CT urogram. The dye highlights blood vessels, tumors, and blockages, giving doctors a clearer view of small abnormalities that may otherwise go unnoticed.
When and Who Needs to Take a CT KUB Scan?
Common Symptoms That Require a CT KUB Scan
- Severe flank or lower-back pain
- Blood in urine (hematuria)
- Repeated urinary tract infections (UTIs)
- Difficulty or pain while urinating
- Unexplained fever with urinary symptoms
Referral by Urologist or Nephrologist
Kidney doctors often recommend a CT SCAN OF KUB WITH CONTRAST when ultrasound results are unclear or when planning surgery for stones, tumors, or congenital anomalies.
List of Parameters
- Stone size and exact location
- Kidney size and cortical thickness
- Hydronephrosis (swelling)
- Ureteric narrowing or dilation
- Bladder wall thickness
- Presence of masses or cysts
Why This Test
- Confirm or rule out kidney stones
- Evaluate recurrent UTIs
- Assess trauma to the urinary tract
- Diagnose congenital kidney anomalies
- Monitor post-surgical changes
When to Take Test
Benefits
Benefits of Taking the Test
- Speed: Completed in under 10 minutes
- Accuracy: Detects stones as small as 2 mm
- Comprehensive: Views bones, vessels, and soft tissue in one scan
- Guidance: Helps plan treatments like lithotripsy or surgery
Illnesses Diagnosed with CT scan of KUB with Contrast
- Kidney and ureteric stones
- Urinary tract infections
- Renal or bladder tumors
- Obstruction or hydronephrosis
- Congenital malformations (duplex kidney, horseshoe kidne
Preparing for test
- Fast 4–6 hours if contrast is planned.
- Drink 1 litre of water the evening before for better images.
- Remove metal objects: jewelry, belts, zippers.
- Inform staff about pregnancy, diabetes, or previous contrast reactions.
Pre-requisites
- Recent serum creatinine report (for contrast studies)
- List of current medications
- Signed consent form
Best Time to Take the CT KUB Scan
- Early morning slots reduce waiting time.
- Avoid scheduling during active menstruation if bladder symptoms are severe.
- For stone follow-up, choose a day when pain is manageable.
Eligibility
- Adults and children over 5 years (pediatric dose protocols available)
- Not suitable for: pregnant women, severe kidney disease (eGFR <30), or known severe contrast allergy.
Procedure for Taking a CT KUB Scan
At the Reception
- Present doctor’s prescription and ID.
- Complete safety questionnaire and sign consent.
- Change into a hospital gown if needed.
During the Scan
- Lie still on the scanner table; straps secure you gently.
- Contrast is injected through an IV line; you may feel warm.
- Machine takes multiple images while you hold your breath for 5–10 seconds.
After the Scan
- Drink extra fluids to flush the dye.
- Resume normal diet and medicines.
- Reports ready in 2–4 hours; urgent cases within 30 minutes.
Caution Before Taking the Test
- Alert staff to any past allergic reactions or asthma.
- Diabetic patients on metformin may need to pause medication for 48 hours post-scan.
- Breastfeeding mothers can resume nursing after 24 hours.
Test Results
Results and Interpretations
| Finding / Observation | Description | General Interpretation / Significance |
|---|---|---|
| Normal scan | No abnormalities detected. | Healthy status, no further action needed. |
| Mild inflammation | Slight tissue swelling seen in the urinary tract. | Requires clinical follow-up to monitor for potential infections. |
| Abnormal mass | Unusual density or shadow indicating possible tumors or cysts. | Possible pathology; further tests such as biopsy or MRI may be needed. |
| Kidney stones | Presence of stones in the kidneys or ureters; size and location noted. | May require treatment such as lithotripsy or surgical removal. |
| Hydronephrosis | Swelling of a kidney due to obstruction; may indicate blockage. | Requires prompt medical attention to relieve the obstruction. |
Risks & Limitations
- Radiation exposure: Modern scanners keep dose within safe limits.
- Contrast allergy: Mild reactions (itching, rash) occur in <1%.
- Kidney stress: Rare in patients with normal kidney function.
- Pregnancy: Not advised for expectant mothers.
Types of CT KUB Scan
Non-Contrast CT KUB
Fast, no dye—ideal for detecting kidney stones and measuring stone size.
CT KUB with Contrast (CT Urogram)
Uses iodine-based dye to map the entire urinary system, revealing tumors, strictures, or infections in the ureters and bladder.
FAQs
Is the CT SCAN OF KUB WITH CONTRAST painful?
No. You may feel a brief warm sensation when the dye is injected.
How long does the scan take?
Total appointment time is 30 minutes; the scan itself lasts 5–10 minutes.
Can I drive home after the test?
Yes, unless you feel dizzy from fasting or have taken sedation (rare).
Do I need hospital admission?
Do I need hospital admission?
What should I do after the scan?
You can typically resume your normal diet and activities immediately after the scan. We strongly encourage you to drink plenty of fluids (water is best) for the 24 hours following your scan to help your kidneys flush the contrast dye from your system.
