Could you share some references for your claim. I have always heard, read and understood that urine is sterile.



This is probably one of the worst "urban" legends that exist.

Its literaly a 5 second google search.


Someone discovered that there are extremophiles in the urinary tract. They... aren't actually a threat because extremophiles.


If it where sterile then we wouldn't test it in medical tests.


Whether or not it's sterile seems to me a completely independent variable from whether or not it's useful to test. Seeing as how it's not completely water, but rather water with various things dissolved in it, the relative levels of those dissolved compounds would something that could be worth knowing.
