Since I am Doctor, I have (supposedly
) a say in this.
1) The urine of all healthy animals is
"Sterile" !!!! 
----------> yes, it does not contain any bacteria at all, and for that matter no fungi, parasites or viruses. The key word here is
healthy. If an animal has an infection, especially of the urinary tract, then, whatever animal or human being it is, its urine is no longer sterile.
2) More importantly, note that, urine of a healthy animal is sterile as long as it stays inside, the moment it comes through the urethra (pee hole
), it becomes infested with millions upon millions of bacteria,
if we also consider that the urethra is unclean/ unwashed, which it is in animals,, but the same would not apply if the urethra and surrounding was washed as well. In that case, since when it comes out, it doesnt touch anything dirty, therefore it stays sterile.
3) Medically:
A: Use of any urine, is inadvisable,
B: However, say we were in a bad situation, like a battlefield, and a soldier got bad wounds, there was no medical aid in sight, not even clean bandages or clothes, then and only then, urine could be used to wash the wound
"But, only after washing the urethra and surrounding of the volunteer" 
4) For all of my Muslim extra nutty friends like fundamentalist
, the Islamic teaching is to respect other people's gods, religion and beliefs, (except for cultists and scientologists that is
), AND
"A Hindu friend of mine told me that Cow urine(+/- Dung) is part of Ajurvedic Medicine. It is belief of the Ulema that the Vedas, including the Rig Veda and the Ajur Ved, are divine scriptures, therefore, since it has been mentioned in them, we should not practice it ourselves but we must respect it just like we respect the Bible.
