Okay, 73 y/o male here. Had 3 TURBTs. First at a local hospital and no catheter. That hurt and burned for about a week. Second and third TURBT were done at Mayo. Both had a catheter. First one I kept in for 4 days. Second one I kept in for 3 days. Catheters may have a little discomfort but nothing like the pain on the first one done locally. For both Mayo catheters I was able to remove it at home following instructions. My urine bag was always filling, but it saved the pain of urine passing through the penis. Embrace the catheter if you don’t want pain when you pass urine. There are jobs you can do while wearing a catheter with a leg band, but I don’t recommend it. After I removed the catheter I took it easy for 2-3 more days. I wish you only the best for your future.
