Intravenous Pyelogram (IVP)
Intravenous Pyelogram (IVP) is an X-ray examination of the kidneys, ureters and urinary bladder. An IVP study uses a contrast medium made of iodine to enhance the images and allow the organs of the urinary tract to be differentiated from the surrounding tissues. The contrast medium is injected into a vein in your arm and its progress through the urinary tract is then recorded on a series of X-rays.
The exam enables the radiologist to review the anatomy and the function of the kidneys and urinary tract. IVP examination is commonly ordered to investigate frequent urination, blood in the urine, or pain in the side or lower back. The IVP exam can enable the radiologist to detect kidney stones, enlarged prostate, tumors, cysts, and other bodily changes and problems.
