Catheterisation is a medical procedure in which a thin, flexible tube - a catheter - is inserted into the bladder to drain urine. This may be necessary when a person cannot urinate independently or when the bladder does not empty completely. There are different forms of catheterisation, depending on the medical need and the patient's physical situation
Catheterisation should always be done on the prescription of a doctor or specialist. Self-catheterisation without medical supervision can lead to serious complications such as infections, damage to the urinary tract or even kidney problems
Why catheterise?
There are several medical reasons why catheterisation may be necessary:
Urinary retention (inability to empty the bladder).
Bladder dysfunction due to neurological disorders (such as MS or spinal cord injury).
After surgery on the prostate, bladder or lower abdomen.
In cases of prolonged immobility.
For accurate urine output measurement in hospital.
Catheterisation can be temporary or long-term, depending on the cause and the recovery process.
Catheterisation in men
In men, catheterisation is technically more complex due to the longer and more tortuous urethra. This increases the risk of discomfort or damage during insertion. Therefore, it is essential that this operation is performed by a trained healthcare provider or after thorough instruction in case of self-catheterisation.
Catheterisation in women
Het risico op urineweginfectie door katheters begint al bij het inbrengen van de katheter. Is de katheter niet steriel? Of is de huid rond de urethra niet goed gereinigd? Dan kunnen bacteriën van de huid of uit de omgeving in de blaas terecht komen. Dat kan weer leiden tot infecties.

Catheterisation: Types
There are different types of catheters, each with a specific application:
Indwelling catheter: stays in the bladder for a longer period of time.
Eenmalige katheter: is used briefly and then removed.
Suprapubic catheter: placed through the abdominal wall.
Condom catheter: applied externally to men.
The choice of catheter type depends on the medical indication, duration of use and patient preference
Eenmalige katheter
A single-use catheter is designed to empty the bladder in a controlled and hygienic manner. The catheter is inserted through the urethra, after which urine is immediately drained. After use, the catheter is removed and discarded. This method is often used several times a day and is suitable for people who want to catheterise independently. Thanks to modern materials and coatings, its use is comfortable and safe.
Indwelling catheter
An indwelling catheter, also called a Foley catheter, stays in the bladder for a longer period of time. The catheter is inserted through the urethra and held in place by a small balloon inflated into the bladder. The urine drains continuously into a collection bag. This solution is often used in people who need long-term care or are temporarily unable to urinate on their own.
Suprapubic catheter
A suprapubic catheter is inserted through a small opening in the lower abdomen directly into the bladder. This is usually done under medical supervision. This catheter is a good alternative when insertion through the urethra is not possible or desirable. As the catheter does not pass through the urethra, there is less risk of irritation or damage to the urethra. The suprapubic catheter is suitable for long-term use and often offers more comfort in daily activities.
Condom catheter
The condom catheter is an external solution for men with urinary incontinence. This catheter is slipped over the penis like a condom and connected to a collection bag. As no tube needs to be inserted into the urethra, this method is less stressful and more comfortable for long-term use. The skin-friendly materials ensure a good fit and minimal risk of skin irritation. The condom catheter is especially suitable for men who do not have urinary retention, but have loss of bladder control.
Self-catheterisation
Self-catheterisation is possible, but requires careful training by a specialist. The patient learns how to insert the catheter in a safe, hygienic way. Regular monitoring and supervision remain necessary to avoid complications.
Disclaimer
Note: Catheterisation is a medical procedure that should only be performed on the advice of a doctor or nurse. Never start catheterisation on your own initiative. The correct choice of catheter, technique and hygiene are essential for safe application.
