    It should be, unless you have some type of infection. Also once it navigates the urethra it may pick up bacteria or upon exiting the body.

    It is, unless you have an infection. In which case, it is not.

    yes, the only time urine is contaminated is if you have an infection. Think about it everytime you go to the doc's u pee in a sterile cup.

    Alexis,

    Urine is created by filtration of sterile blood through the kidneys. So, the substances within the blood that is filtered would also be sterile. So, unless there's an infection in the bladder that contaminates the urine as it passes through, urine should be considered sterile.

    Someone correct me if I'm off base here.

    Yes, it is sterile in the bladder, barring infection. Our bladders are a sterile environment. When the urine comes out it probably isn't sterile anymore because of bacteria at the entrance to the urethra and on our skin, thats why you have to use that cloth at the Dr.'s office to get a "clean catch" specimen. It is probably still not sterile, to be sterile is a complete absence of pathogens and it only takes one to defeat that!

    Since this is a student forum and since I'm a stickler regarding terminology, I'd like to point out that sterility is the absence of any living organism not just pathogens.

    You are correct, I didn't go broadly enough with that point, did I !?

    It is sterile till it passes through the meatus(sp?)

    so it is sterile since the blood that the kidney filter is sterile... unless there is contaminants which is whether pathogenic or non pathogenic...

    the only time that the urine becomes unsterile is when it passes the urethra and the urinary meatus where normal flora inhabits...

    :wink2::wink2:

    thanks guys!!!!
