Your doctor has prescribed self-catheterization for you because you are having trouble urinating naturally. This problem can be caused by injury, disease, infection, recent surgery (especially urinary incontinence or prolapse procedures), hysterectomy, or other conditions.
Many people urinate by self-catheterization (also called intermittent catheterization). Self-catheterization simply means inserting a clean, thin, flexible tube (catheter) into the bladder to empty urine. This helps you empty your bladder when it won't empty by itself or won't empty all the way. You were shown in the hospital how to do this procedure. The steps below should help you remember how to do it correctly.
