Why it's done

A CT urogram is used to examine the kidneys, ureters and bladder. It lets your doctor see the size and shape of these structures to determine if they're working properly and to look for any signs of disease that may affect your urinary system.

Your doctor may recommend a CT urogram if you have signs and symptoms — such as pain in your side or back or blood in your urine (hematuria) — that may be related to a urinary tract disorder.

A CT urogram may be helpful in diagnosing urinary tract conditions such as:

• Kidney stones
• Bladder stones
• Complicated infections
• Tumors or cysts
• Cancer
• Structural problems
