Intravenous Pyelogram (IVP)
Intravenous Pyelogram (IVP)
What is Intravenous Pyelogram?
An Intravenous Pyelogram (IVP) is an x-ray examination of the kidneys, ureters and urinary bladder. An IVP study uses a contrast material to enhance the x-ray images. The contrast material is injected into the patient’s system and its progress through the urinary tract is then recorded on a series of quickly captured images. The exam enables the radiologist to review the anatomy and the function of the kidneys and urinary tract.
What will the exam be like?
Once you arrive at the imaging department you will be asked to change into a gown. You will also be asked to remove jewelry, or any metal objects that could obscure the images.
The individual who will perform the study is known as a Radiologic Technologist. The technologist will position you on the table and a preliminary x-ray is obtained to check for adequacy of the bowel preparation. Contrast material is then injected in a vein in your arm. Contrast excreted in the urine shows outlines of the kidneys and demonstrates the inner “collecting system” and ureters. As the contrast material is processed by the kidneys, a series of images is captured to determine the actual size of the kidneys and to show the collecting system as it begins to empty. Some kidneys don’t empty the contrast at the same rate and delayed films from 30 minutes to three or four hours may be requested.
During the imaging process you may be asked to turn from side to side to enable the technologist to capture views from several angles.
Near the end of the exam you may be asked to go to the restroom to empty your bladder so that an additional film can be taken of you urinary bladder after it empties.
The contrast material used for IVP studies will not discolor your urine or cause any discomfort when you urinate.
Aside from a minor sting from the injection of contrast material, an IVP causes no pain.
How do I prepare for the exam?
You will be informed of what to do to prepare for your exam when you make your appointment.
If you have had a previous reaction to contrast, have a history of asthma or allergies, heart or sickle disease, or are diabetic, please inform your ordering physician and the technologist prior to your test.
Typically, the day before the exam you will be restricted to a clear diet and must avoid dairy products. You will be instructed to take a laxative the evening prior to your exam.
Please follow the instructions given to you when scheduling your exam.
How long will the exam take?
An Intravenous Pyelogram (IVP) will generally take 1 hour. However, at times, it may be necessary to take delay films and this would make the test longer.
Following the exam:
You should have no discomfort or pain from this exam. You may return to your normal daily activities unless otherwise instructed.
A Radiologist will study the images and a typed report will be sent to your designated health care provider.
Women should always inform their doctor or technologist if there is any possibility that they are pregnant.
