    Barring evidence of a urinary tract infection, yes, urine is sterile. As it exits the body, it is contaminated by the opening of your urethra where bacteria is present. If a Dr. wants a sample as pure as possible. they do a "clean catch" sample where you are given some anti-bacterial towelettes to wipe yourself. You are then instructed to first let some urine out into the toilet and then "catch" urine mid-stream to get the purest possible sample.

    Good question. Yes it is sterile until it comes into contact with bacteria, or UTI (Urinary Tract Infection), or the atmosphere.

    Until it leaves the body. Then, it's not.
