Intermittent Self Catheterisation (ISC)
Intermittent self-catheterisation (ISC) is used to treat bladders that do not empty fully.
You will be taught how to insert a urinary catheter into your bladder by a health professional – this can be done in a hospital, clinic or at home. Urinary catheters are inserted into the bladder at intervals throughout the day, or when you feel the need to go to the toilet. It is sometimes necessary to catheterise during the night as well. Once the urine has drained out, the catheter is removed. Most catheters for ISC are used once and then thrown away. However, some are designed to be cleaned and reused.
Most people feel apprehensive about performing Intermittent Self Catheterisation. It can be a bit awkward to start with but with practice you will soon become confident, your local health care professional will offer you support until you feel able to manage alone. Most people go on to say that they find it easy to self-catheterise after a time. There are different types of catheters – your health care professional will help you to find the right one for you.
How do I self-catheterise?
Before use, all catheters should be stored in a dry area, lying flat and straight. If the packaging is damaged, do not use the catheter.
It is very important to wash your hands before touching or inserting the catheter – you may choose to use a fresh baby wipe if there is no wash hand basin in the toilet.
Once you have washed your hands, do not touch anything else except your catheter.
Most catheters have a sticky back patch which allows you to open it and secure it to a surface nearby, such as a wall or sink, making it easier to access when you are ready to insert it into the urethra.
Preparation – For women:
You have to ensure that your vulva (intimate area between your legs) is clean. A daily shower or bath is recommended using a mild soap, but when you go out it is useful to keep a small pack of baby wipes in your handbag or pocket to enable you to ensure the area is clean.
There are several ways to catheterise – you can learn to insert the catheter while sitting on the toilet or in your wheelchair, when standing or by putting one foot up onto the toilet seat to enable you to locate your urethra more easily. You can experiment and decide which way feels most comfortable. If you are a woman and find it hard to locate your urethra, try using a mirror to see where your urine comes out. Once you have done this several times you will probably not need a mirror. You can do it over the bath if it’s easier.
Preparation – For men:
You have to ensure that or the area around the tip of the penis is clean. It may be that a daily shower or bath is sufficient but when you go out it is useful to keep a small pack of baby wipes in a pocket to enable you to ensure the area is clean. Men may stand or sit to perform intermittent self-catheterisation
When you are ready, take the catheter by the drainage end from the packaging and gently push the other end into your urethra. When the catheter has reached the bladder, urine will drain from it. Make sure all the urine has drained from your bladder before removing it.
To remove the catheter, gently twist it and pull down. Don’t worry if it doesn’t come out first time. Try again, continuing to pull gently.
Catheters that are designed to be used more than once should be cleaned after each use with soap and water, dried with a clean tissue and kept in a sealed plastic bag or container.
If I self-catheterise, will I be more likely to get an infection?
It is important to wash your hands when possible before inserting your catheter to help reduce the risk of infection. If this isn’t possible, there are catheters available that require minimal handling, helping to cut the risk of infection.
You might also benefit from drinking cranberry juice. It is thought that cranberry juice helps to line the bladder making it harder for any infection to thrive. If taking Warfarin, cranberry juice should be avoided.
Please note that people with diabetes should consult their doctor before drinking cranberry juice. Anyone who has Interstitial Cystitis or related bladder diseases should also avoid cranberry juice.
How can I use ISC safely when away from home?
If it is likely that good toilet facilities won’t always be available when you are away, you might like to try a different type of catheter – e.g. one that is self-lubricating, or one that needs minimal handling (see above). There is also an intermittent catheter with its own drainage bag attached, making it ideal for use when no toilets are available.
I have poor eyesight and find it difficult to handle a catheter. What can I do?
You need to have good control of your hands because it can be a fiddle and you should have reasonable eyesight so you can see what you are doing. But, there are special devices available to help you if you find it hard to handle a catheter. Accessories such as mirrors to attach to your leg to aid catheterisation are also available so you can see what you’re doing more easily, without having to hold a mirror in your other hand.
Some men find it easier to use disposable plastic tweezers that come in sterile blister packs, allowing a firm squeeze on the catheter tube without compromising sterility. Using one hand to manage the meatus (opening), you can use the other to insert the tip of the catheter from a short distance. Once the tip of the catheter has been introduced, you can then move your hand from the meatus to the solid end of the catheter, remove the tweezers, and carry out the rest of the process as usual.
Please contact your continence advisor or urology nurse before attempting to use intermittent catheters.
