Urine is the waste product secreted by the kidneys that in mammals is a yellow to amber-colored, slightly acidic fluid discharged from the body through the urethra.[1] Urine is not considered to be a sterile liquid.[2]

Urine may be used to flush out the preputial sac when the foreskin does not retract.
