What To Think About

• Abnormal results from a kidney scan may be further investigated by tests such as a kidney biopsy, ultrasound, intravenous pyelogram (IVP), or computed tomography (CT) scan. For more information, see the topics Kidney Biopsy, Abdominal Ultrasound, Intravenous Pyelogram (IVP), or CT Scan of the Body.
• Another type of scan (radionuclide cystogram) may be done to determine whether urine is flowing backward from the bladder into the ureters. For more information, see the topic Cystourethrogram.
