CT Scan of Kub with Contrast

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.

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.

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.

• Stone size and exact location
• Kidney size and cortical thickness
• Hydronephrosis (swelling)
• Ureteric narrowing or dilation
• Bladder wall thickness
• Presence of masses or cysts

• Confirm or rule out kidney stones
• Evaluate recurrent UTIs
• Assess trauma to the urinary tract
• Diagnose congenital kidney anomalies
• Monitor post-surgical changes

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.

• 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

• Kidney and ureteric stones
• Urinary tract infections
• Renal or bladder tumors
• Obstruction or hydronephrosis
• Congenital malformations (duplex kidney, horseshoe kidne

• 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.

• Recent serum creatinine report (for contrast studies)
• List of current medications
• Signed consent form

• 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.

• 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.

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.

• 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.

• 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.
