What is this test?
A CT scan focused on the urinary tract, including the kidneys, ureters, and bladder (often referred to as KUB). This imaging technique uses X-rays combined with computer processing to produce detailed cross-sectional images of the urinary system’s anatomy and function. It helps identify a wide range of urinary tract disorders by providing clear visualization of the entire pathway from kidneys to bladder.
What is it used for?

• Detecting kidney stones (renal calculi), including their size, location, and potential obstruction
• Identifying urinary tract infections (UTIs) and complications such as abscesses
• Diagnosing tumors or masses within the kidneys, ureters, or bladder
• Assessing obstruction or narrowing in the urinary tract causing urinary retention or impaired flow
• Evaluating causes of hematuria (blood in urine) or unexplained flank pain
• Investigating congenital abnormalities or structural defects
• Guiding treatment plans for surgical or interventional procedures related to urinary tract issues

Who should get this test?

• Patients presenting with blood in urine (hematuria), persistent flank or abdominal pain
• Individuals with suspected or known kidney stones or urinary tract obstruction
• Patients with recurrent urinary infections or unexplained urinary symptoms
• Those with abnormal findings on ultrasound or other preliminary tests requiring detailed imaging
• Patients under surveillance for urinary tract tumors or cysts

Preparation Required:

• Depending on the protocol, patients may be advised to fast for a few hours before the test to optimize image clarity
• Hydration is often encouraged to ensure good urinary tract visualization and contrast clearance if contrast agents are used
• Some protocols require intravenous or oral contrast dye to enhance imaging detail — kidney function is evaluated prior to contrast administration to ensure safety
• Inform your healthcare provider about any allergies, especially to contrast material

How is the procedure performed?
The scan is usually rapid, lasting 5 to 10 minutes. Patients lie supine on the CT table while the machine captures multiple X-ray slices of the urinary tract. Contrast dye, if used, is administered via an IV line and helps highlight the kidneys, ureters, and bladder more clearly. Patients must remain still during imaging and may be asked to hold their breath briefly.
Risks & Safety:
CT scans involve exposure to ionizing radiation, which is carefully minimized to balance image quality with patient safety. Use of contrast dye carries a small risk of allergic reactions and potential kidney effects, which are closely monitored. The overall benefits of accurate diagnosis typically outweigh these risks.
Results:
A radiologist analyzes the images and generates a detailed report describing the anatomy and any abnormalities such as stones, masses, inflammation, or obstructions. This comprehensive information guides further clinical decisions and management.
Short Statement:
A precise CT scan of the kidneys, ureters, and bladder to detect stones, infections, tumors, or structural abnormalities, providing crucial insights for urinary tract health.
