Indwelling Urinary Catheters
An indwelling catheter is applied the same way as an intermittent catheter. However, such catheters are not removed after urination and are left in their place. The indwelling (Foley) catheter is held in place with the help of a small water-filled balloon, which prevents it from falling out of its place.
Urine drains from the bladder into a large urine bag. This collection bag can easily be strapped on to your leg with the help of leg straps and adhesives. An indwelling catheter does not always work due to gravity, and sometimes needs to be attached to a valve to facilitate quick and easy drainage of the urine. Typically, an indwelling catheter needs to be changed every three months.
