IVP (Intravenous Pyelogram) IVP is an x-ray examination of the urinary system. The urinary system consists of the kidneys, ureters and bladder. These structures are difficult to see on x-rays so a contrast material consisting of iodine is injected into the blood stream to highlight the organs of the urinary system. Please tell your doctor if you have any allergies to iodine. Common reasons to undergo an IVP include: frequent or painful urination blood in the urine pain in the back or sides How do I prepare? Your doctor should give you detailed instructions on how to prepare for your IVP. Please inform your doctor if you are allergic to iodine prior to your exam date. Your doctor may have to prescribe an additional medication prior to the exam. You will be asked to eat and drink only clear liquids on the day before your exam and will most likely need to take a laxative on the day and evening before your exam. This is intended to clear your colon so that the structures of your urinary system are easier to identify. What will I experience during the exam? The exam will begin with preliminary x-rays that help the technologist locate your kidneys. The technologist will start an IV in your arm and inject the contrast material. Some people experience a warm sensation or a metallic taste in their mouth. These are normal side effects and will go away within a few minutes. Once the injection has been completed, the technologist will begin taking a series of x-rays. You will be asked to move into some different positions for these x-rays. After the initial series of x-rays are completed, the technologist will have a Radiologist review them. At that time, the Radiologist may request additional films. You may be asked to empty your bladder and take another x-ray. After all the x-rays are done, the IV will be removed from your arm. What will I experience after the exam? Following the IVP, you will be able to resume normal eating and drinking and return to normal activities. The contrast material is colorless and will be excreted from your body in the urine.
