Intermittent catheterization is a medical procedure used to empty the bladder at regular intervals. It involves inserting a thin, flexible tube called a catheter into the bladder through the urethra. This method is often recommended for individuals who have difficulty urinating due to conditions like spinal cord injuries, multiple sclerosis, or other urinary retention issues. The procedure can be performed by the patient themselves or by a caregiver, depending on the individual's needs. Intermittent catheterization helps prevent urinary tract infections and bladder damage by ensuring the bladder is emptied regularly. Proper hygiene and technique are essential for safe and effective use.
