An indwelling catheter is a thin tube inserted into the urethra for long-term use. The catheter drains urine into a bag that is either attached with a strap around a leg underneath pants or a skirt so that you can be active during the day, or it is hung from the side of a bed (generally used at night, or for those who remain in a bed for long periods of time).
Indwelling catheters are often used during many medical procedures, including most surgeries, regardless of whether or not the individual has incontinence. Also, in some cases of constant urine leakage an indwelling catheter is used.
If left in place for long periods of time, infection will most likely occur, even with catheters that have an antimicrobial coating.
It is best to try and avoid long-term use of this type of catheter whenever possible. You should feel free to ask your healthcare team to not use this type of catheter when possible or to question its use, and/or to remove it as quickly as possible to reduce risk of infection. Monitoring for infection when in use is absolutely necessary!
