Some people have no incontinence. If you are one of the lucky ones, you will not need any of the products.

I wore a pull up (diaper, whatever you want to call them) over the catheter and kept a pad under me at all times until the catheter came out. I never needed the pad, but still glad I had it. Yes, get the largest ones you can buy.

After catheter came out, my routine was a diaper with a guard tucked (not taped) inside. I would then change out the guard throughout the day as needed. At night I would sleep only in a diaper. Then once per day I would put on a new diaper.

I tried skimping on products, but ended up using Depends for both diapers and guards. Walmart brand irritated my skin, but no problems once I started using Depends only. I did use Tena guards for a while, and they are a quality product too.

My routine has worked well for me. All a small price to pay to be cancer-free (from what I know, fingers crossed).
