Has your doctor told you to have an IVP test? Or have you heard about it somewhere? The name may sound a bit complicated. But don't worry, it's not as big a deal as you think. Today, we'll talk about what this IVP test is, why it's done, how it's done, and how to prepare for it in a very simple way that you can understand.
Simply put, what is this IVP?
The full name of IVP is Intravenous Pyelogram . This is actually a special X-ray test. It is used to see how your urinary system is working. This means that this test helps to identify problems with your kidneys, ureters, and bladder .
During this test, a special liquid is injected into a vein in your arm. We call this a 'contrast dye' . It's like a dye. This liquid travels through your blood to your kidneys. It then passes through your kidneys and through your ureters to your bladder. The areas where this liquid is located show up very clearly on an X-ray as white. The X-ray images taken at that time allow the doctor to easily see if there is a blockage, tumor, or stone anywhere in your urinary system.
This test is called by several other names.
- Intravenous Pyelography
- IVP
- Intravenous Urography
- IV Urography
But one thing must be said. These days, this IVP test is not really used that much. Because there are more modern tests like CT scan, MRI scan, or Ultrasound scan that can take clearer, more detailed images, doctors are turning to them more often.
What kind of diseases was the IVP test used to diagnose in the past?
Although not widely used today, doctors used this IVP test in the past to diagnose a variety of conditions. For example:
- Check for tumors or fluid-filled cysts anywhere in the urinary system.
- Identify benign prostatic hyperplasia, a common condition in men.
- Find the exact location of kidney stones .
- Some people have certain problems with the urinary system that they are born with (congenital urinary abnormalities) . Identify them.
- Check for scarring anywhere in the urinary system due to frequent urinary tract infections (UTIs) .
In addition, this test is sometimes recommended to diagnose specific kidney conditions such as `Medullary sponge kidney` and `Renal papillary necrosis`.
How do you prepare for this test?
Before you have an IVP test, your doctor will ask about your complete medical history. There are a few things you should definitely tell them at this time:
- If you are pregnant or suspect you may be pregnant .
- If you have allergies to certain things, especially things like iodine, which is used to cleanse the skin.
- If you have had any allergic reactions to this type of contrast dye in the past .
In addition, your doctor will advise you on what to eat and drink before the test. Often, you will be asked to stop eating and drinking for a few hours before the test. You may also be asked to clean your bowels thoroughly, such as by taking a laxative . When your bowels are clean, the urinary system shows up very clearly on the X-ray images. That's why they do it.
Does the bladder need to be full before the test?
No. You will be asked to urinate just before the test begins. Once your bladder is empty, you can clearly see the new contrast dye filling in.
What happens during the test?
An IVP test is usually performed by a radiologist or radiologic technologist. It usually takes about an hour. However, if your kidneys are working a little slower, it may take longer.
Here's what happens step by step:
1. Inserting the cannula: First, a small cannula (peripheral IV) is inserted into a vein in your arm. The contrast dye is injected into your body through this.
2. The first X-ray: Before the dye is injected, you will lie down on the X-ray machine and an X-ray picture of your belly and pelvis will be taken.
3. Injecting the dye: Then, the contrast dye is injected into the vein through the inserted cannula.
4. Taking X-ray pictures: As the dye travels through your blood, filters through your kidneys, and travels down your urinary tract, several X-ray pictures are taken every few minutes. It is very important that you remain still during this time.
5. Urination again: After the bladder is filled with dye, you will be asked to urinate again.
6. Final X-ray: After urinating, another X-ray picture is taken to see if the bladder is completely empty.
What happens after the test and are there any risks?
When the test is finished, the cannula in your hand will be removed and a small plaster will be applied to the area. After that, you can go about your normal activities.
The most important thing is to drink plenty of water after the test. When you drink a lot of water, the contrast dye that was injected into your body is quickly flushed out of your body with urine.
You may feel some slight discomfort when the contrast dye is injected into your body. However, this usually goes away after a while.
| Things that can be felt normally | Description |
|---|---|
| A small sore where the cannula was inserted. | When the cannula is inserted, it feels like a small prick. |
| Feeling hot | When the dye goes into your body, you may feel your whole body getting a little warm. |
| A metallic taste in the mouth | The mouth may taste like iron. |
| A slight itch | It may feel like your body is being scratched a little. |
Severe Allergic Reactions
A serious allergic reaction to contrast dye is rare , but it can happen. In such cases, symptoms may include:
- Difficulty breathing
- Low blood pressure
- Hives
- Swelling of the mouth or throat
If you experience any of these serious symptoms, don't delay. Go to the nearest hospital's Emergency Department (ETU) as soon as possible.
What can we learn from the results?
The radiologist will review your X-ray images and write a report to see if there is anything unusual. The report will be sent to the doctor who recommended the test for you. Your doctor will explain the results to you within a few days.
IVP results may reveal things like:
- Abnormal shape, size, or position of the organs of the urinary system.
- Enlarged prostate gland.
- Blockages in the urinary tract.
- Cysts or tumors.
- Damage or scars caused by infection.
If the results are abnormal, your doctor will tell you what to do next. He or she may order additional tests (ultrasound, MRI, CT scan, blood tests to check kidney function, biopsy). Or he or she may start treatment right away.
When should you call your doctor?
If you experience any of the following symptoms after the IVP test, notify your doctor immediately.
- Blood in the urine (hematuria)
- Dark urine appearance
- Lower abdominal or back pain
As mentioned earlier, if you experience any serious allergic symptoms such as difficulty breathing or hives, go straight to the Emergency Department (ETU) .
