My Foley was not put in during pre-op, in fact the last time I went to the bathroom was in pre-op. I walked down the hall with my IV's and went to the bathroom for one last time, the old fashion way, before surgery.
The prostate is brought up last in a little bag through the large incision above your navel. Kind of like a tea bag.
After my surgery, I requested and received my "Surgical Report" which tells you what they did and in what order. It was pretty interesting reading. They did a "time out" just before surgery which is when everyone tells who is present in surgery.
