A catheter is a thin rubber tube inserted into the bladder to drain urine. It is secured with a small balloon and can remain in place for variable lengths of time. The catheter is connected to a bag to collect urine. Regular catheter care is needed to prevent infection, which includes cleaning the catheter area daily and keeping the urine bag below the level of the bladder. Signs of potential issues include a stopped or reduced urine output, wetness, cloudy or bloody urine, or pain and fever, and should be reported to a registered nurse.
