I always tried to wait to pee when I wasn't near my stand. A while back I read about the pissing in mock scrapes thing and tried it. Worked every single time. Even in spots where there was no visible deer sign.

Actually just made one the other day after leaving one just because I had to pee. Made a small one and came back the next morning and it had been hit and there was a new scrape right beside it. Also made one under a small cedar just to see if they'd make a scrape on one because I had never seen it. Put a camera on it. Waited 3 days. Returned and they had hit it and also made a rub on that same cedar. Had pictures of a few bucks and does. I'm sold on it.
