Yes, a small amount of blood right after surgery is normal. If the amount of blood increases very much or if it continues daily for too long, give your WOC nurse a call. Different people also pass different amounts of mucous as well, so don't be surprised when stuff starts coming out. Mine was hardly anything at first, and it looked like the same type of reddish fluid that was coming out of my JP drainage tube. Then over the weeks it turned milky clear and started coming a lot so that I was passing a good "handful" of mucous almost every time I sat down to urinate... and eventually a couple weeks before my step two, I had some bright red blood. You may even see other colors or *gasp* a bit of food since it is possible for the loop ileo to pass tiny amounts of food or waste through to the j-pouch... All of this is normal and no cause for worry, but if you ever are concerned and want peace of mind, just call your nurse - that's what they are there for!
