Catheter Insertion involves inserting a flexible tube which is inserted into an opening in the body, it is designed for removing fluid. There are many different types of Catheter which can be used in different ways which is dependent on the type of treatment you require.
The main types of Catheter are listed below:
Intermittent urinary catheters
These are used to store urine from the body when a patient is unable pass urine naturally. In many cases intermittent urinary catheters are the most reccomended, they are instered throughout the day for long enough that a patient can drain their bladder and removed after.
The catheter is usually inserted into the bladder through the urethra which is the tube responsible for carrying urine out of your body. It is normally lubricated to reduce the risk of discomfort upon insertion.
The other end of the catheter is left open-ended which will allow you to drain the urine into the toilet or attached to a bag which collects the urine. When the flow of urine stops the catheter is then removed and replaced.
Indwelling urinary catheters
An indwelling urinary catheter is similar to a intermittent urinary catheter interms of insertion how ever when this is inserted it is left in place. It is held in place by a water-filled balloon preventing the catheter from falling out.
The urine is collected and then drained from a tube which is connected to a bag that stores the urine before being emptied. The bag can either be strapped to the side of your leg or attached to a stand which can be placed on the floor.
These catheter types are often fitted with a valve which can be opened to allow the urine to be drained, these catheters should be changed at least once every 3 months.
Similar to the indwelliung urinary catheters a suprapubic catheter is also left in place however the catheter is inserted through a hole in the abdomen. This procedure can be carried out under a general or local anaesthetic.
This catheter can be secured to the side of your body and attached to a bag strapped to your leg. This catheter can be used for those with problems urinating or undertaking dialysis treatment. these catheters are changed every 6-8 weeks.
