almost. not when it leaves the body though.. if you would have read one more paragraph from the link you posted you would have seen this

"Urine is sterile until it reaches the urethra where the epithelial cells lining the urethra are colonized by facultatively anaerobic Gram negative rods and cocci.[4] Subsequent to elimination from the body, urine can acquire strong odors due to bacterial action"
