CT Urogram at Cadabams Diagnostics | Book Your Scan Today

CT Urogram is a modern imaging test that gives your doctor a clear 3-D view of your kidneys, ureters, and bladder in one scan. At Cadabams Diagnostics, we use advanced low-dose CT scanners to deliver high-quality images with minimal radiation. Whether you have blood in urine, recurring infections, or need cancer screening, our team makes the process quick, safe, and comfortable.

A CT Urogram combines X-rays and computer processing to create cross-sectional images of the entire urinary tract. Unlike routine ultrasound, it detects stones as small as 1 mm and highlights subtle cancers that may be missed on other tests. At Cadabams Diagnostics, the scan is completed in under 15 minutes and reports are ready within a few hours, helping you start treatment sooner.

How computerized tomography captures urinary tract images

• A rotating X-ray tube circles your body while detectors measure radiation absorption.
• A computer reconstructs these data into thin “slices,” stacked to form a 3-D model of kidneys, ureters, and bladder.
• Iodine-based contrast dye is injected to highlight blood vessels and inner lining of the urinary system.

Difference between CT scan and CT urogram

Standard CT urogram

• 120 kVp, full-dose contrast
• Best for complex cancer staging

Low-dose CT urogram

• 80–100 kVp, iterative reconstruction
• Ideal for stone detection and follow-up

Split-bolus protocol

• Two-phase contrast injection in one scan pass
• Halves radiation and shortens breath-holds

• Kidney size and shape – detects shrinkage, masses, or cysts
• Ureter patency – confirms no obstruction or strictures
• Bladder wall thickness – thickening may indicate infection or tumor
• Stone detection – size, location, density (HU)
• Contrast excretion delay – flags functional impairment

• Blood in urine evaluation – pinpoints source quickly
• Recurrent urinary tract infections – finds hidden stones or fistulae
• Cancer screening – detects renal, ureteral, or bladder tumors early
• Trauma assessment – evaluates injury after accidents

Common symptoms that require urogram tests

• Visible or microscopic blood in urine (hematuria)
• Severe flank pain suggesting kidney stones
• Repeated urinary tract infections (UTIs)
• Difficulty or pain during urination
• Unexplained weight loss or fatigue

Age and risk factors

• Adults over 40 with above symptoms
• Smokers or workers exposed to dyes/chemicals
• Patients with diabetes, hypertension, or prior pelvic radiation
• Children above 14 when ultrasound results are inconclusive

• Quick diagnosis – 10–15 minute scan time
• Non-invasive procedure – no catheter required
• Detailed 3D images – aids surgical planning
• Early detection of abnormalities – improves treatment outcomes

• Kidney stones – uric acid, calcium oxalate, struvite
• Urinary tract cancers – transitional cell carcinoma, renal cell carcinoma
• Structural abnormalities – duplicated collecting system, horseshoe kidney
• Ureteral strictures – post-surgical or radiation fibrosis

Fasting guidelines

• Nothing by mouth 4 hours before the scan (clear fluids allowed)
• Take regular medications with a sip of water

Medication adjustments

• Metformin: withhold 48 hours post-contrast
• Diuretics: skip morning dose to prevent dehydration

Clothing recommendations

• Wear loose, metal-free attire; we provide gowns if necessary
• Remove jewelry, belts, and underwired bras

• Kidney function tests – serum creatinine & eGFR within 30 days
• Allergy screening – questionnaire about shellfish, iodine, prior reactions
• Pregnancy test for women – urine β-hCG for ages 12–50 unless documented hysterectomy

• Morning appointments – preferred for fasting patients
• Emergency 24/7 availability – walk-in or ambulance referrals accepted

• Adults and children above 14 – weight ≥40 kg for contrast dose
• BMI considerations – scanner accommodates up to 200 kg (440 lb)
• Contrast dye compatibility – assessed via pre-scan questionnaire and blood tests

Before the scan – what to expect

• Check-in at reception with doctor’s prescription
• Change into gown; IV line inserted for contrast
• Optional oral hydration to dilute contrast

During the scan – step by step

1. Lie supine on the CT table; straps secure you gently.
2. First non-contrast images localize kidneys.
3. Contrast injected automatically; you may feel a warm flush.
4. Hold breath for 5–10 seconds during each of three phases (arterial, venous, excretory).
5. Total table time: ~10 minutes.

After the scan – recovery tips

• Rest 15 minutes in observation area
• Drink 500 ml water to flush contrast
• Resume normal diet and medications unless advised otherwise

• Inform about allergies – latex, iodine, or shellfish
• Remove metal objects – hearing aids, hairpins, coins
• Hydration requirements – arrive well-hydrated unless fasting is instructed

Radiation exposure risks

Effective dose is ~3–5 mSv—similar to six months of natural background radiation. Our low-dose protocols cut exposure by up to 40 % without reducing image quality.

Contrast dye reactions

• Mild: nausea or warm flush (1–3 %)
• Moderate: rash or hives (<0.04 %)
• Severe: anaphylaxis (<0.001 %)

Who should avoid the test

• Pregnant women (unless emergency)
• People with severe iodine allergy or previous anaphylaxis
• Patients with eGFR <30 ml/min (risk of contrast-induced nephropathy)
