Shall we talk about the IVP (Intravenous Pyelogram) test that helps you learn about your kidneys?

Sometimes doctors order various tests to see if there is any problem with our kidneys or urinary system, right? That is one such test called IVP. Although it was used a lot in the past, it is now done less often. But it is very important for you to be aware of this test called `Intravenous Pyelogram (IVP).`

What is IVP?

Simply put, an IVP is a special X-ray test that looks at the inside of your kidneys and urinary tract (the passageways through which urine passes). It is also called an Intravenous Urography. Imagine, a doctor wants to see how your kidneys and bladder are working and if there is anything wrong with them. That is when this IVP helps.

This is what happens. A special liquid called an ``iodinated contrast material'' is injected into your body, that is, into a vein. This liquid travels throughout your body with the blood, including to your kidneys. Then, as this liquid passes through your kidneys, ureters, and bladder, a series of X-ray pictures are taken. Because of the special liquid, these organs appear white on the X-ray pictures. That's when the doctor can see exactly what's going on inside.

What was IVP used for in the past?

In the past, before the advent of modern technology, the IVP test was used to diagnose many diseases. Here are a few examples:

• Kidney stones: Check to see if you have these kidney stones, which many people develop, and where they are.
• Enlarged prostate in men: This is also a condition that occurs in men as they age.
• Tumors or cysts in the kidneys, bladder, or urethra: These may or may not be cancerous.
• Scarring from a urinary tract infection (UTI): Sometimes, a urinary tract infection (UTI) can cause internal scarring.
• Congenital anomalies of the urinary tract: This also helped to detect any congenital abnormalities or defects in the urinary tract.

What replaces IVP now?

But as I said before, doctors don't use the IVP test very often these days, because newer methods have come along that are better, clearer, and sometimes less invasive.

Now most used:

• Ultrasound: This allows you to see the kidneys and urinary system without injecting a special fluid. This is often the first test done.
• CT Scan (Computed Tomography - CT scans):This is also sometimes done with or without an iodinated contrast dye. This allows for very clear, cross-sectional images of the inside of the body.
• Magnetic Resonance Imaging (MRI) scans: This also sometimes uses a different type of dye called gadolinium contrast dye. MRI can produce even more detailed, three-dimensional (3D) images.

Doctors are now turning to this over IVP because these new methods can detect problems in the kidneys and urinary system much better and in greater detail.

What kind of symptoms would a doctor order this type of test for?

Typically, if you have these symptoms, a doctor may order an imaging test (a test that looks inside) to check your kidneys or urinary system, such as:

• If you have blood in your pee, this is something you should definitely tell a doctor about.
• If the urine turns cloudy.
• If you have lower abdominal pain or lower back pain.
• If you have pain in your side.

Symptoms like these indicate that there may be a problem with the kidneys or urinary system. That's when tests like this are needed to see exactly what's going on.

Who performs the IVP test?

This IVP test is usually performed by X-ray technicians and radiologists. After the images are taken, the radiologist reviews the images, compiles the information into a report, and sends it to your treating doctor.

How are our kidneys and urinary system formed?

When we talk about the kidneys and urinary system, there are three main parts. These are what doctors look at with an IVP (but now with those other scans).

• Kidneys: We have two kidneys. These are the organs that filter our blood, remove waste products, and make urine. They act like a filter.
• Ureters: These are two tubes that carry urine produced in the kidneys to the bladder.
• Bladder: This is the small sac that collects and stores urine. When it is full, we feel the need to urinate.

So, these types of imaging tests help to find out if there are any problems in these organs, such as stones, tumors, or cysts.

How to do an IVP test (How is it done?)

Although IVP is not used much these days, it's still good to know how to do it. Here's how it's usually done:

1. First, you will lie on a bed under an X-ray machine. Then, a picture of your abdomen and pelvis will be taken before a special liquid (contrast dye) is injected.

2. Next, that special liquid is injected into your vein.

3. After the fluid is instilled, you will be laid back on the bed and several X-ray images will be taken as the fluid passes through the kidneys and down the ureters to the bladder.

4. Then you will be given a short time to empty your bladder, that is, urinate .

5. I'll make you lie down on the bed again and take a few more pictures.

This is how the IVP test works.

What are the possible complications of the IVP test?

As with any medical test, there may be some minor discomfort during this IVP. But don't worry, most of the time these are not serious.

When the special liquid (contrast dye) is injected into the body, many people may experience one or more of these temporary symptoms:

• A slight burning sensation at the injection site.
• Feeling a little hot .
• An itchy feeling that doesn't go away .
• A metallic taste in the mouth.

These will disappear after a while.

Some people, between 3 and 13 out of 100 , may have a minor abnormal response to this liquid. In such cases:

• Nausea may occur.
• Vomiting may occur.
• A flushed feeling may occur, making the face and chest red .

These are also usually temporary.

However, very rarely , severe allergic reactions to this liquid can occur. These include:

• Breathing difficulties.
• Low blood pressure.
• Red spots or hives on the skin.
• Swelling in your mouth or throat.
• Cardiac arrest.

Severe reactions like this are rare, but if they do occur, they need to be treated quickly.

You are more likely to experience this type of adverse reaction if you have any of the following pre-existing medical conditions:

• Various allergies.
• Congestive Heart Failure.
• Diabetes (Diabetes Mellitus).
• Chronic Kidney Disease.

That's why a doctor asks you all these questions before doing a test like this. Also, new, less invasive tests have greatly reduced this risk.

How long does the IVP test take? How long does it take to recover?

An IVP test usually takes about an hour , but if your kidneys are working a little too hard, it may take a little longer.

It doesn't take long to recover. The most important thing after the test is to drink plenty of water . That way, the special fluid (the contrast dye) that was injected into your body will quickly be flushed out with your urine.

What time should I see a doctor?

The symptoms I told you about earlier, that is:

• If there is blood in the urine,
• If the urine is dark in color,
• If you have pain in your lower back,
• If there is pain in the side of the pelvis,

If these things continue, definitely see a doctor, as it could mean there is something wrong with your kidneys, ureters, or bladder.

Also, if you experience symptoms of a severe allergic reaction (anaphylaxis) (for example, difficulty breathing, hives, swelling of the mouth and throat), whether to the contrast dye or anything else, you should see a doctor immediately or go to a hospital emergency department.

Remember briefly.

Okay, so, let me ask you to remember some of the most important things we've talked about.

An IVP is an X-ray test used to look at the kidneys and urinary system. A special liquid (contrast dye) is injected into the body.

However, IVP is rarely used these days. Instead, more accurate and less invasive methods such as ultrasound, CT scan, and MRI scan are more commonly used.

If you have symptoms such as blood in your urine, dark urine, or pain in your back or groin, a doctor may order imaging tests to check for problems in your kidneys or bladder, such as stones or tumors.

The most important thing is that if you have any unusual symptoms, do not ignore them and see a doctor for advice.
