How to Avoid Catheter Blockages & Obstructions

One of the most common complications that can occur for catheter users is catheter blockage. Catheter blockages often form from catheter encrustation, or buildup made of minerals, salts, and crystalline deposits which can block the eye holes of the catheter and prevent urine from draining from the bladder.

These obstructions often begin as small obstructions and can develop fully into a complete blockage. More often than not, these blockages will affect long-time catheter users.

As with other urological issues, it’s important to resolve catheter blockages right away. Leaving them unresolved can lead to pain, urinary retention, bladder, and kidney infections. They can ultimately cause urine to flow back into the kidneys, leading to serious kidney issues or bloodstream infections, such as renal failure and sepsis.

If you suspect you may have a urinary catheter blockage or obstruction, the process of removing the blockage will vary depending on the type of catheter you have.

If you have a suprapubic catheter / indwelling urinary catheter (long-term catheter), your catheter will be placed into the bladder to drain your urine into a drainage bag. If you notice that the drainage bag is empty, follow these steps.

• Check your underwear. Snug or tight undergarments can block urine from flowing into the drainage bag. We recommend wearing loose-fitting underwear to prevent blockages from occurring.
• Check for kinks. Guide your hands over the length of your catheter tubing and urinary bag to check for any kinks that could be blocking the flow of urine.
• Check your straps. Assess your leg straps to ensure they are fitting correctly and aren’t causing an obstruction in your tubing or drainage bag.
• Check your drainage bag placement. Make sure that your urinary bag or drainage system is positioned below your bladder while sitting or laying down, so the urine is able to flow easily.

An intermittent catheter is used several times a day when you need to use the restroom. If no urine is expelled after insertion:

• Check for kinks. Guide your hands over the length of your catheter tubing to check for any kinks that could be blocking the urine from flowing successfully through the tube.
• Check the lubrication. If you use lubrication gel when inserting your catheter, it can potentially block the end of your tubing. Wait a minute or two to allow the lubrication gel to dissolve.
• Check for correct insertion. If your urine does not begin to flow after insertion, gently remove the catheter to make sure it was properly inserted. Women can sometimes place their catheter in the vagina by mistake, and men need to insert the catheter far enough into the urethra for the bladder to empty. In male patients, 10cm of the catheter should be visible after insertion.
• Try to relax your muscles. Try to take three deep breaths and check your positioning while ensuring the catheter is being inserted at the correct angle. Tension and anxiety can make insertion more difficult.
• Check the size of your catheter. If the catheter is not the right size for your specific needs, insertion and drainage of your bladder can be difficult.
• Don’t force anything. Never force your catheter in. Using force could cause pain and further complications. If you fail to insert your catheter, take a break and try again after a few minutes.

If you are unable to insert your catheter or your bladder won’t drain after trying the above methods, seek medical attention immediately.

There are various factors that can be a sign of a a blocked catheter or obstruction. It is important to pay attention to these warning signs to prevent your catheter from becoming fully obstructed.

Bypassing: Urine leaking around the catheter can indicate that urine is unable to drain through the catheter and will leak around the catheter instead.

Stomach Cramps: Pain and cramping can be a sign of bladder irritation or the result of too much pressure being placed on the bladder due to constipation.

Encrustation: The build-up of salt and minerals, like calcium, from urine can block your catheter tube, resulting in an obstruction. Bacterial infections can also cause the urine to be more alkaline, leading to more crystals in the tubing.

Drainage Bag Location: If the drainage bag is not located below the bladder, this can cause improper drainage to occur.

Additional Factors: Blood clots, bladder stones, and kidney stones can also cause catheter obstructions.

• Consult your doctor. If you begin to take a new antibiotic or other types of medication, ask your doctor if you should also change catheter types.
• Check the pH of your urine for high alkaline levels. Urinary pH levels between 4.5 to 8 are considered normal, but anything below 6.7 can increase the chances of encrustation. Citrates and sodium can help make the urine less alkaline.
• Try different catheter types. If you use a straight tip catheter, a new catheter type, such as a coudé tip catheter, can help navigate obstructions due to enlarged prostates. Lubricated, antimicrobial intermittent catheters can also be a helpful alternative.
