CT Urography scan in Delhi is the most comprehensive CT examination for evaluating the entire urinary tract — from the kidneys to the bladder, including the collecting system, renal pelvis, ureters, and urethra. It combines the diagnostic power of three-phase CT imaging with a dedicated delayed urogram phase to provide a complete “road map” of the urinary system. This guide covers everything you need to know about CT Urography — its indications, preparation, procedure, cost, and where to get the best scan in Delhi.
According to RadiologyInfo.org (American College of Radiology), CT Urography scan in Delhi and worldwide is the gold standard for evaluating the urinary tract in patients presenting with haematuria. The American Urological Association (AUA) recommends CT Urography as the primary imaging modality for investigating both gross and microscopic haematuria.

What is CT Urography?
CT Urography (CTU) is a multiphase CT examination that specifically evaluates the urothelium (lining) of the entire urinary collecting system — renal calyces, renal pelvis, ureters, and urinary bladder. It is the most comprehensive non-invasive imaging investigation for haematuria (blood in urine) workup and urothelial cancer detection.
A complete CT Urography includes:
- Non-contrast phase — Detects calculi (stones) and baseline assessment
- Nephrographic phase (~90 seconds) — Optimised for renal parenchyma assessment and small renal mass detection
- Excretory/Urogram phase (~10–15 minutes after injection) — Contrast fills the collecting system and ureters, allowing evaluation of the urothelium for tumours, filling defects, and strictures
CT Urography has largely replaced conventional intravenous urography (IVU) as the gold standard for comprehensive urinary tract imaging.
Quick Answer: CT Urography scan in Delhi is a multiphase CT scan providing comprehensive imaging of the kidneys, renal pelvis, ureters, and bladder. It is the gold standard for haematuria workup and urothelial cancer detection. The full exam including delayed urogram phase takes 30–45 minutes.
Why is CT Urography scan in Delhi Done?
- Haematuria workup — The primary indication; detecting the source of blood in urine throughout the urinary tract
- Urothelial carcinoma detection — Transitional cell carcinoma of the renal pelvis, ureter, or bladder
- Renal cell carcinoma staging — Detailed assessment of renal tumours and venous involvement
- Ureteric strictures — Identifying benign or malignant narrowing of the ureter
- Ureteric duplication anomalies — Detecting congenital ureteric abnormalities
- Kidney stones — Complete urinary tract stone mapping
- Pyelonephritis and renal abscess — Comprehensive infection assessment
- Post-surgical urinary tract assessment — After urological surgeries, cystectomy, or ureteric reimplantation
- Urinary fistula assessment — Identifying abnormal connections between urinary tract and other structures
Symptoms That Require CT Urography
- Haematuria — visible (gross) or microscopic blood in urine
- Recurrent urinary tract infections with unknown structural cause
- Unexplained flank pain with haematuria
- Abnormal findings on ultrasound (renal mass, ureteric dilation)
- Suspected ureteric injury or stricture
- Urinary symptoms in patients with known malignancy
- Post-cystoscopy with abnormal ureteric orifices requiring upper tract assessment
Who Should Get CT Urography?
- Adult patients with unexplained haematuria (the primary indication)
- Patients with suspected upper tract urothelial carcinoma
- Patients with recurrent UTIs requiring structural evaluation
- Known renal stone patients requiring comprehensive urinary tract mapping
- Post-urological surgery follow-up patients
- Patients with congenital urinary tract anomalies requiring detailed assessment
Preparation Before CT Urography
- Fasting — Fast for 4–6 hours before the scan
- Hydration — Drink 1–2 glasses of water 1 hour before the scan to ensure mild bladder filling
- Kidney function test — Serum creatinine required before IV contrast injection
- Inform the team — About contrast allergies, kidney disease, diabetes, and current medications
- Metformin — Stop 48 hours before (diabetic patients; consult your doctor)
- Avoid urination — Immediately before the scan to ensure adequate bladder filling for urogram phase
- IV diuretic — Furosemide may be given before scanning at some centres to better distend the ureters
Step-by-Step Procedure for CT Urography
- Registration — Present prescription and creatinine report at Edge Imaging, Paschim Vihar
- IV Cannula Placement — IV access established; furosemide injected if protocol requires
- Non-contrast Phase — Baseline CT from kidneys to bladder acquired
- IV Contrast Injection — Iodinated contrast injected via power injector
- Corticomedullary Phase (~25–35 seconds) — Renal cortex enhancement phase for lesion detection
- Nephrographic Phase (~90 seconds) — Homogeneous renal parenchyma phase; ideal for small renal mass detection
- Waiting Period — 10–15 minutes rest while contrast fills the collecting system
- Excretory/Urogram Phase — Final CT shows opacified collecting system, ureters, and bladder
- 3D Reconstruction — Maximum Intensity Projection (MIP) images created for panoramic urinary tract view
- Post-scan observation — 15–30 minutes monitoring
- Report delivery — Comprehensive urography report within 90 minutes
How Long Does CT Urography Take?
CT Urography takes longer than standard CT due to the mandatory delayed urogram phase. The scan phases cover approximately 30–45 minutes of scanner time. Total visit time at Edge Imaging & Diagnostics, Paschim Vihar, including preparation, waiting for the excretory phase, and post-scan monitoring is approximately 90–120 minutes.
Is CT Urography Safe?
CT Urography scan in Delhi is safe when performed with appropriate pre-scan assessment. Kidney function must be checked before contrast injection. Adequate hydration before and after the scan protects the kidneys. At Edge Imaging, we use low-osmolar contrast agents and maintain full emergency facilities for patient safety.
Is CT Urography Painful? CT Urography scan in Delhi is not painful. You may feel a brief warm flushing sensation during contrast injection and mild pressure from the bladder as contrast fills it. The IV cannula insertion is a minor pinch. The actual CT scanning is completely painless and non-invasive.
Risks and Complications
- Radiation exposure — Higher than single-phase CT due to multiple phases; justified for haematuria workup
- Contrast allergy — Rare; managed with pre-medication in high-risk patients
- Contrast nephropathy — Minimised by pre-scan kidney function test and adequate hydration
- Incomplete ureteric filling — Occasionally ureters may not be fully opacified; may require additional delayed images
Benefits of CT Urography scan in Delhi
- Gold standard for haematuria workup — Single examination evaluates entire urinary tract
- Replaces IVU — More comprehensive than traditional intravenous urography with better image quality
- Detects urothelial tumours — Sensitive for filling defects and urothelial thickening throughout the collecting system
- Complete renal assessment — Multiple phases characterise renal masses and parenchymal disease
- 3D visualisation — MIP reconstructions provide complete panoramic urinary tract views for surgical planning
- Non-invasive — Provides comprehensive information without cystoscopy or ureteroscopy
Accuracy of CT Urography scan in Delhi
CT Urography has a sensitivity of 96–100% for upper tract urothelial carcinoma and 89–95% for bladder tumours. For renal cell carcinoma, sensitivity exceeds 94%. For ureteric stones, sensitivity is 95–98%. These figures make CT Urography the most accurate single imaging test for comprehensive haematuria evaluation, per guidelines from the American Urological Association (AUA) and European Association of Urology (EAU).

Frequently Asked Questions — CT Urography in Delhi
1. What is the difference between CT Urography and CT KUB?
CT KUB (NCCT or CECT) evaluates the kidneys, ureters, and bladder in 1–3 phases. CT Urography scan in Delhi is a more comprehensive multiphase study specifically designed to evaluate the urothelium (inner lining) of the collecting system with a mandatory delayed excretory phase showing contrast-filled ureters and bladder — ideal for detecting urothelial tumours and filling defects.
2. Why is CT Urography scan in Delhi performed for haematuria?
Haematuria can originate from any part of the urinary tract — kidney, ureter, or bladder. CT Urography evaluates the entire urinary tract in a single examination, identifying the source of bleeding whether it is a renal tumour, ureteric stone, or urothelial carcinoma. It is the recommended first-line investigation for adult haematuria workup.
3. Does CT Urography replace cystoscopy?
CT Urography complements but does not replace cystoscopy. CT Urography scan in Delhi is excellent for evaluating the upper urinary tract (kidneys and ureters). Cystoscopy provides direct visualisation of the bladder mucosa and is required for definitive bladder lesion assessment. Both are often performed together in haematuria workup.
4. How is CT Urography different from IVU (Intravenous Urogram)?
IVU (intravenous urogram) is a plain X-ray-based technique that shows the urinary tract after contrast injection. CT Urography uses multi-phase CT imaging with far superior resolution, soft tissue detail, and 3D reconstruction capabilities. CT Urography has replaced IVU in most clinical settings due to its superior accuracy.
5. Can CT Urography detect bladder cancer?
CT Urography detects bladder tumours as filling defects or focal wall thickening in the excretory phase with sensitivity of 89–95%. However, cystoscopy remains the gold standard for bladder cancer detection and biopsy. CT Urography scan in Delhi is more valuable for upper tract urothelial cancer and staging of known bladder cancer.
6. How long does the excretory phase take in CT Urography?
The excretory phase is acquired 10–15 minutes after IV contrast injection, once the contrast has been filtered by the kidneys and fills the collecting system and ureters. You will rest comfortably for this waiting period at our Paschim Vihar centre before the final CT acquisition.
7. Is CT Urography safe for elderly patients?
CT Urography scan in Delhi is generally safe for elderly patients. Kidney function must be assessed beforehand as age-related reduction in renal function increases contrast nephropathy risk. Adequate hydration before and after the scan is essential. Our team carefully assesses all elderly patients before proceeding with contrast administration.
8. What does the CT Urography report include?
A comprehensive CT Urography report from Edge Imaging includes: renal parenchyma assessment (masses, cysts, cortical scarring), collecting system findings (filling defects, strictures, papillary necrosis), ureteric assessment (course, calibre, filling defects), bladder assessment (wall thickness, filling defects, perilesional fat stranding), and relevant retroperitoneal lymph nodes.
9. What preparation is needed for CT Urography?
Fast for 4–6 hours, get serum creatinine tested, stop Metformin 48 hours before if diabetic, drink 1–2 glasses of water 1 hour before, avoid urinating immediately before the scan to maintain bladder filling, and arrive 30 minutes early for IV cannula placement.
