Hi: The same thing pretty much happened to me. I had no blood for over a week after catheter removal, then all of a sudden bright red blood came out of my penis when I was having a BM. The brightness of it scared me -- I thought I might have broken an internal stiitch ot something. I called City of Hope and they said it was normal and advised me to keep drinking tons of liquids, get more rest and don't strain to urinate or move the bowels. It stopped about
three days later. I had my urine tested a week ago and it looked clear, but analysis showed it had blood in it.
So, bleeding is part of the program for a lot of us. You may see some tiny scaby things too. I was told that the only thing to be concerned about is large clots or constant dripping of blood from the penis.
Hope this helps and your husband feels better.
