An indwelling urinary catheter is one that is left in the bladder. You may use an indwelling catheter for a short time or a long time.
An indwelling catheter collects urine by attaching to a drainage bag. The bag has a valve that can be opened to allow urine to flow out. Some of these bags can be secured to your leg. This allows you to wear the bag under your clothes. An indwelling catheter may be inserted into the bladder in 2 ways:
An indwelling catheter has a small balloon inflated on the end of it. This prevents the catheter from sliding out of your body. When the catheter needs to be removed, the balloon is deflated.
If the catheter becomes clogged, painful, or infected, it will need to be replaced right away.
