What is a catheter?
People who have difficulty emptying their bladder use a catheter, which is a thin tube that is passed into the bladder (usually through the urethra) and allows the urine to drain freely. There are two main types of catheter:
Intermittent catheters – also called Nelaton or “in/out” catheters are inserted into the bladder temporarily to allow it to empty and are then removed.
Indwelling catheters - also called Foley catheters. These are designed to remain in the bladder continuously for longer periods of time.
Catheters should only be used after a thorough assessment by a healthcare professional.1
