An intravenous pyelogram (IVP) is an x-ray examination of the kidneys, ureters and urinary bladder that uses iodinated contrast material injected into veins.
An x-ray (radiograph) is a noninvasive medical test that helps physicians diagnose and treat medical conditions. Imaging with x-rays involves exposing a part of the body to a small dose of ionizing radiation to produce pictures of the inside of the body. X-rays are the oldest and most frequently used form of medical imaging.
When a contrast material is injected into a vein in the patient's arm, it travels through the blood stream and collects in the kidneys and urinary tract, turning these areas bright white. An IVP allows the radiologist to view and assess the anatomy and function of the kidneys, ureters and the bladder.
An intravenous pyelogram examination helps the physician assess abnormalities in the urinary system, as well as how quickly and efficiently the patient's system is able to handle waste.
The exam is used to help diagnose symptoms such as blood in the urine or pain in the side or lower back.
The IVP exam can enable the radiologist to detect problems within the urinary tract resulting from:
- kidney stones
- enlarged prostate
- tumors in the kidney, ureters or urinary bladder
How to prepare for your IVP exam:
- Nothing to eat or drink after midnight
- Some bowel preparation is necessary for the exam. The preparation is necessary for an optimal
exam. Please pick up a preparation kit at the CVMC Medical Imaging department 1 day prior to
your exam at no additional charge.
