An indwelling catheter (sometimes also called a foley catheter) is one that is left in the bladder for a period of time. It is held in place by a small balloon. It may either drain freely attached to a urine drainage bag or leg bag or it may be used with a catheter valve to enable intermittent emptying of the bladder.
Indwelling catheters can be hazardous if used incorrectly. Read the guidance below for important safety information.
