Step 1: Gather Your Supplies. The first step in self-catheterization is to ensure that you have all of the supplies you will need. Depending on what type of catheter you have, this could include the catheter you intend to use, moist towelettes or soap and water, a dry towel, a water soluble lubricant, and a toilet or other drainage receptacle.
Step 2: Wash Your Hands. It is very important to make sure your hands are clean by washing them with soap and water, or a moist towelette, before beginning self-catheterization.
Step 3: Stop and Look at Your Catheter. Before you use your catheter, make sure that none of the packaging has been previously opened or damaged.
