There are so many factors playing in that besides you urinating in it. I make mock scrapes all the time and pissed in them as well and never had a deer spook and the scrapes are a meer 15yds from my stand.
Were you sprayed down? were your boots scent free? how did you make the scrape? blah blah blah. Most likely your **** was thee only factor not played into it.
Remember when skunk pee was bottles and used, back in the days, that was the cover scent many ol' timers used along with others. That didn't spook deer and you would think it would because only time a skunk scented was when there was trouble so you would think it would alarm the deer, but it doesn't.
This topic can be beat to death and everyone will have their opinions from their own trials & run-ins.
Me, myself, I have had zero issues with this & I have been fortunate to have hunted many states & provinces.
