Who can say exactly what but I had surgery in Baltimore and while I had my catheter still inserted, we stayed in Annapolis. After the catheter was removed, my wife drove us to SC over six hundred miles. It felt so good having had the surgery and then having that bag attached to my leg, we could have driven another day easily. The best part was that I found out that I could sit without peeing my pad. In fact, I had the same pad on all that day. And another interesting sidelight, I stood at the urinal like a big boy and with my pants half way down, did my business. The sun was shinning and it was one of the best days of my life. Go for it
