What is the term for a catheter that remains in the bladder to drain urine into a bag?

An indwelling catheter is specifically designed to remain in the bladder for an extended period, continuously draining urine into a collection bag. This type of catheter is usually used for individuals who are unable to urinate on their own due to various medical conditions or after certain surgical procedures. The advantage of the indwelling catheter is that it allows for a consistent and reliable method of urine drainage without requiring frequent insertion and removal.

The term "Foley catheter," which is another name often used interchangeably with indwelling catheter, is recognized for being a specific type of indwelling catheter that includes a balloon to help keep it securely in place within the bladder. While a Foley catheter can specifically refer to a well-known brand or model of an indwelling catheter, the broader term of indwelling catheter encompasses all similar devices that serve the same function.

Intermittent catheters, on the other hand, are used for one-time drainage of urine and are removed immediately after use. External catheters, also known as condom catheters, are placed outside the body and are not used for draining urine from the bladder directly. Understanding these distinctions is key to grasping how various catheters function and their purpose in urinary care.
