1. Purpose:
A comprehensive CT scan of the KUB (Kidneys, Ureters, and Bladder) with contrast is used to enhance the visualization of the urinary tract, helping to diagnose issues such as kidney stones, tumors, or structural abnormalities more effectively.

2. Contrast Administration:
Contrast material is injected intravenously to highlight the kidneys, ureters, and bladder, improving the clarity of images and allowing for better assessment of blood vessels and soft tissues.

3. Preparation:
Patients may be required to fast for a few hours before the scan. They may also need to drink oral contrast or receive intravenous contrast during the procedure.

4. Imaging Procedure:
The patient lies on a motorized table that moves through the CT scanner. Multiple cross-sectional images of the KUB region are captured, with contrast enhancing the detail of the urinary tract structures.

5. Radiologist Analysis:
The images are reviewed by a radiologist to identify abnormalities, assess organ function, and evaluate any potential issues such as stones, tumors, or obstructions in the urinary tract.

6. Post-Procedure Care:
Patients are advised to drink plenty of fluids to help flush the contrast material from their system. Monitoring for any adverse reactions to the contrast dye is also important.
