Some people’s bladder muscles do not work as well as others. If you are unable to fully empty your bladder, you are at greater risk of developing urinary tract infections which can cause kidney damage. When this happens, your doctor or nurse may recommend clean intermittent catheterization (CIC).  CIC means inserting a catheter through the urethra (bladder opening) into the bladder on a regular basis. Urine flows out of the catheter emptying the bladder.  Your doctor or nurse will tell you how frequently you will need to catheterize.
CIC is used to help manage abnormal bladder function. It prevents the bladder from over filling which can lead to kidney damage. It drains any residual urine that may remain in the bladder if it does not fully empty on its own. This helps to prevent bacteria growth which may cause bladder infections.
Always notify your doctor or nurse if you experience pain during catheterization.
