IVP (Intravenous Pyelography)
IVP stands for intra venous pyelography. This test is performed to detect the function of the urinary tract, and detect abnormalities of the kidneys, ureter and bladder (KUB).
How should I prepare myself ?
You will be requested by your doctor to be on an empty stomach for atleast 5 hours before the procedure or perhaps even fasting overnight. You will be prescribed a mild laxative either in pill or liquid form at bedtime, the night prior to the test in order to clear your abdomen of faeces and gas.
What should I tell the doctor ?
You should inform your doctor of any ailments you suffer from such as asthma, heart or kidney disorders, history of allergy, diabetes or a previous reaction to contrast media. This test also involves use of x-rays, thus if you are pregnant, this test should be avoided.
How will this test be performed ?
After being asked to lie on an x-ray table, you will be given a contrast medium via an intra venous route. This drug (dye) gets released into the kidneys and is visible on x-rays, thus the anatomy and various abnormalities of the kidney can be detected. X-ray pictures will then be taken at appropriate intervals, a tight abdominal band may be placed across your abdomen during this test - this may cause slight discomfort. The entire test may take between 30 - 60 minutes, but this time period could be increased if your kidney is not functioning to optimal levels, and if the radiologist feels that a few more x-ray pictures are of value at a later stage.
What will I experience during the injection - are there any side effects ?
While this drug is injected, you may experience a feeling of warmth all over your body, or a slight pain in the arm of injection. These features are not uncommon. In case of an allergy reaction, you may experience nausea, vomiting, or hives / rash. This type of reaction is termed a minor reaction and can be controlled by monitoring and intra venous medication. A severe type of reaction could occur in rare instances, in these cases, there may be difficulty in breathing and / or cardio vascular collapse.
The chances of reaction are greatly reduced by using a non ionic contrast which is freely available in India.
