  • Renal Scan

  • A renal scan is used to test how well the kidneys are functioning. It can be used to look for kidney tumors, cysts, obstructions and other problems. You should be well hydrated for the test.

    What to expect

    • Upon arrival, you will be asked to lie on your back. The camera will be under you.
    • You will be injected with a small amount of radioactive material. The material will go to your kidneys and bladder. There are no side effects to this injection.
    • Images of you bladder and kidneys will be taken for approximately 30 minutes. The radiologist will determine if more images are needed.
    • You may need an additional study, which requires us to inject a small dose of Lasix and you will be asked to go to the restroom to empty your bladder. More images of your kidneys and bladder will be taken for 30 minutes. Once this portion of imaging is complete, you will be asked to go to the restroom and empty your bladder again. You will return to the imaging room for one more image.

    Your images will be read by a board-certified radiologist and the report will be sent to your doctor.
