What is CT Urography?

CT Urography uses CT images to evaluate the excretory system (ureter, urinary bladder and kidneys)

A CT Urography is performed if:
  • You have blood in the urine
  • You are suspected of having or have Urinary tract cancer

How do I prepare for the CT Urography?
  • When you schedule your CT Urography scan, you will receive detailed instructions on how to prepare. For example, you may be instructed to not eat or drink anything for at least four hours before your scan begins. 
  • You are encouraged to drink clear liquids before your scan and have a full bladder, not to urinate just before the scan.
  • You may also take your prescribed medications prior to your scan.
  • Pregnant or lactating women are advised not to get a CT Urography done.

  • Serum Creatinine reports(not older than 4 weeks) are required to check for the health of your kidneys in case we need to use contrast media to get better images during the scan. The values help us decide on the type of contrast media to be used.

How is the CT Urography scan done?

  • The process you will follow when you go for a CT Urography scan is as follows:
  • If a contrast dye is used, it will be given to you by mouth (oral contrast) or injected into a vein in your arm (intravenous). 
  • Before the test, you will need to change into a hospital gown and remove any jewellery or metal objects that you are wearing.
  • You will be taken into the scanning room. If you have been given oral contrast, you will need to wait for about 45 to 60 minutes before being taken to the scanning room. This waiting time is needed for the contrast to move through your digestive tract.
  • The CT scanning machine is shaped like a doughnut. You will be made to lie on the imaging bed. After you have been positioned properly, the helper leaves the scanning room. The technician present in the control room can see you through a glass window. If there is no visibility to the scanning room from the control room patients are fully monitored through closed circuit television screen. The technician communicates with you through an intercom.
  • The bed is moved slowly through the scanner. The X-ray machine will rotate around you and produce several images of thin slices of your body. You will need to lie very still while the images are being captured. 
  • When needed, the technician will instruct you to hold your breath for several seconds so that you remain still. The scanning takes about 15-20 minutes on the scanning table.
  • After which you will be kept under observation to monitor any allergic reaction 
  • Sometimes, a delayed scan/re-scan may be required at times. 
  • The images created during the scan will be reviewed by the radiologist.

  • Also you need to do fasting for 4 hours before the scan.
