Does a person have to make sure when going to the bathroom before davening and in general that the מקום המילה is clean and what about shabbos? Is it a problem if by mistake urine get on our body?
There should be no need for a person to check himself there, as it is generally clean. If someone accidently got urine on their body, although we should try to prevent this from happening if the is urine on one’s body, he may still daven and say brachos, as long as it doesn’t smell. If the urine is on ones underclothes it is also not an issue because that is covered with another article of clothing.
