Get the proper catheter and take it with you in remote areas. Keep things sterile.I tried tournament fishing for a couple of years and had a fellow that got teamed up with me and about 10:00am he pulled out a tube and put it where it needed to go and pee'd way out in the water.I turned around and said next time warn me,I could have gone all day without seeing that!
So I know about it and he was told it would take surgery to fix it and it may not even work for long.
So sorry you had to deal with that.Just seeing it ruined my day.
Yes, a bladder can break. Plus the back up of urine can infect the kidneys. Don't wait so long.
