Asymptomatic Bacteriuria
What Is It?
When a significant number of bacteria show up in the urine, this is called "bacteriuria." Finding bacteria in the urine can mean there is an infection somewhere in the urinary tract. The urinary tract is the system that includes:

- The ureters – thin tubes connecting the kidneys to the bladder
- The bladder, where urine can be stored
- The urethra – the final pathway to move urine from the bladder to outside the body.
In asymptomatic bacteriuria, large numbers of bacteria are present in the urine. However, the person has no symptoms of a urinary tract infection (asymptomatic means without symptoms).
