Snowbird said, "Urine is a good disinfectant."
I don't think that is correct.
To be a disinfectant, urine would have to destroy bacteria. There is no evidence that it does this.
It is even debatable that a person who is not ill has sterile urine. Even if it was sterile, "sterile" means "free of bacteria," not "destroys bacteria."
There have been instances in military field medicine when medics used human urine. Henry VIII's surgeon Thomas Vicary recommended that all battle wounds should be washed in urine. Urinating on a wound to clean it in an emergency has become fodder for urban legend, but new research debunks the idea that urine is sterile.
Urine is not sterile, even before it comes out of you and gets contaminated by your skin. Bacteria are present at low levels in the urine of healthy people not suffering from a urinary tract infection.
But if "golden showers" are your thing... take a regular shower afterwards.
