Sometimes we have difficulty urinating, or we may have blood in our urine. Or when there is an accident in the lower abdomen, that is, in the groin, we need to see if there is any damage inside. Especially when something like this happens to the male, a special test is called `(Retrograde Urethrogram)` to find out the exact cause. We sometimes call this `(RUG)` for short. So, you must be curious to know about this too. Shall we talk about this `(RUG)` test in detail, very simply, today?
What is this (Retrograde Urethrogram) test? Simply put...
Okay, first let's look at what a Retrograde Urethrogram (RUG) is. This is actually a special test that doctors use. It looks to see if your urethra (the tube through which we urinate ) is damaged or if scar tissue has built up and is blocking the flow of urine . Think of it like a water pipe that gets clogged with dirt and stops the water from flowing.
This test is mostly done on men . If you have had an injury or accident to your lower abdomen or groin area, or if your doctor thinks you have scar tissue in your urethra, this ``(RUG)`` test may be done.
What time is a RUG test done?
Now you're probably thinking, "Okay, what kind of situations would you do this in?" Take a look:
A doctor may order a retrograde urethrogram (RUG) in an emergency (for example, after an accident). Or it may be done to check for ongoing symptoms. You may need a RUG if you have an injury to your lower abdomen or groin area and:
- If you have bleeding from the opening of your penis (i.e. where urine comes out).
- If you can't urinate .
Not only that, a doctor may perform this ``RUG'' test for several other reasons:
- If they think your urethra is narrowed (a `stricture`) due to an illness, blockage, or injury.
- If they have difficulty inserting a catheter (a flexible tube that helps you urinate ).
- Sometimes it is necessary to insert a catheter that goes all the way into the bladder (transurethral bladder catheterization). However, before doing so, if the doctor suspects that there is a problem with your urinary tract, he or she will use this ``RUG'' test to make sure that it can be done safely.
What can be found in this RUG test?
This ``Retrograde Urethrogram`` test helps a doctor find things like:
- Urethral stricture : This means that the urethra is blocked.
- There is some blockage in your urinary tract.
- Damage to your urinary tract: For example, whether there is a rupture, a new opening or hole (fistula), or a small pouch-like structure (diverticula).
Is this a painful test? There's nothing to be afraid of!
A question that many people have is, "Does this hurt?" No, a ``Retrograde Urethrogram'' shouldn't really hurt. However, you may feel a little discomfort, a little strange, during the test and after urinating . This is normal. But if you feel any pain, it's best to tell your doctor right away.
How does this (Retrograde Urethrogram) work?
It's very simple. In a ``Retrograde Urethrogram'', a doctor injects a special liquid (called ``contrast'') into your urethra. This is done by inserting a small tube or the tip of a blunt syringe through the hole (``urethral meatus'') at the end of your penis, where urine comes out. As this liquid flows into your bladder (the bag where urine collects), the doctor takes ``X-ray'' pictures. These pictures are used to find out what problems there are in your urethra.
To be precise, this `contrast` liquid makes the urethra clearly visible on the `X-ray`. Only then can we see exactly if there is anything wrong inside.
Is there anything I need to prepare before the RUG?
This is the best! You don't have to do anything special to prepare before a `(RUG)`. You can just be normal.
What happens during the test? Let's see?
Okay, now let's see what happens when you do a `(Retrograde Urethrogram)`. Don't be scared, I'll tell you simply.
- First, you will be turned to one side on a table under an X-ray machine. You will also be asked to bend one of your legs to the side. The doctor or an assistant there will help you to position yourself correctly.
- Then, the doctor will clean the area around the opening of your penis and apply an antiseptic solution (such as iodine) .
- Sometimes, a topical numbing lubricant can be applied to the inside of your penis to numb your urethra . It takes a few minutes for it to work.
- Next, the doctor will insert a small tube through the hole at the tip of your penis . The tube will be slowly guided down your urethra a short distance. At this point, they may gently move your penis into position and ask you if you feel any discomfort. This shouldn't hurt – if it does, you should definitely tell them.
- Now, the previously mentioned `contrast` liquid is injected into the urethra using a syringe. This liquid is what makes your urethra visible clearly on the `X-ray` images.
- As the contrast fluid travels through the urethra to the bladder, the doctor takes pictures with an X-ray machine.
- Sometimes, you may be asked to urinate into a container to see how this contrast fluid passes out of your body, and you may be asked to take X-ray pictures.
That's all that's happening. There's nothing to be afraid of as you might think, right?
What to expect after the test?
After the test, you may feel a little uncomfortable when you urinate . You may also notice a little blood when you urinate . This is normal, don't worry. This discomfort will subside after about a day . The most important thing is to drink plenty of water . This will help flush out any remaining contrast fluid.
Are there any risks or side effects to this RUG test?
A retrograde urethrogram is actually a very low-risk test . However, there are some very rare side effects that can occur:
- Infection.
- An allergic reaction to the contrast fluid.
- Any damage to the urinary tract or bladder.
These are very rare things, but it's good to be aware of them.
What are the results of the RUG test? What do they mean?
If your test results are ``normal,'' it means that fluid is flowing through your urethra without any blockages . If so, your symptoms may be caused by something else.
Other results may indicate that your urethra is damaged, narrowed, or blocked.
Sometimes, if the RUG test alone doesn't provide enough information, your doctor may also want to do a cystoscopy , which involves inserting a small camera into your urethra.
How long does it take to know the results?
The time it takes for you to know the results depends on the reason you are having this test.
- If you have an injury and need emergency medical treatment , the doctor will receive the test results right away , so they can treat you quickly.
- Unless it's an emergency , you should be able to know the results within a few days .
If the results are abnormal, what do you do next?
Now you might be thinking, "Okay, if the results say there's a problem, what do we do next?"
The next steps you take will depend on what's causing your problem. Your doctor will talk to you about treatment options. These may include:
- Procedures to widen your urethra (such as urethral dilation) .
- Surgery (such as urethroplasty) .
Don't worry, the doctor will explain the treatment that is most suitable for you.
When should I see the doctor again?
If you have any of the following after the test, you should definitely see your doctor:
- If you have pain when urinating or are unable to urinate at all.
- If you have discomfort or bleeding for more than a day after the test.
- If there are signs of infection (e.g., swollen penis, fever).
- If you have questions about your test results.
It's best not to think twice about talking to a doctor about anything like this, right?
So, let's look at some things to remember from this? (Take-Home Message)
Okay, we've talked a lot about this `(Retrograde Urethrogram)` or `(RUG)` test, haven't we? Finally, remember these things:
A retrograde urethrogram is a simple, low-risk test.
This will only take a few minutes.
However, this gives doctors a lot of important information about possible problems with your urinary tract.
This test is also used in emergencies or after an injury to determine if there is any damage that is not visible on the outside .
So, if a doctor asks you to have this test, don't be unnecessarily afraid of it. Think of it as something that will help you maintain your health. If you have any other questions, be sure to talk to your doctor.
👩🏽⚕️ Additional questions (FAQs)
💬 What is a RUG (Retrograde Urethrogram) test?
This is a specialized X-ray test performed to determine if the urethra in men is torn or narrowed (stricture) anywhere, especially due to an injury or stone blockage.
💬 Why is this called 'retrograde'?
Normally, urine flows from the bladder to the outside. However, in this test, the dye (contrast) that is clearly visible on X-rays is injected into the urethra (from the outside). This means that the urine travels backwards on its way, which is why it is called retrograde.
💬 Is this something you should definitely do if you get hit in the lower abdomen in an accident?
Absolutely! If there is blood coming from the urethra in such an accident, this RUG test should always be performed before catheterizing the patient. Because if the urethra is broken and the catheter is forcibly inserted, the urethra can be completely destroyed and the patient may have difficulty urinating for the rest of his life.
