Learn About Asymptomatic Bacteriuria

What is the definition of Asymptomatic Bacteriuria?

Most of the time, your urine is sterile. This means there are no bacteria growing. On the other hand, if you have symptoms of a bladder or kidney infection, bacteria will often be present and growing in your urine.

Sometimes, your health care provider may check your urine for bacteria, even when you do not have any symptoms. If enough bacteria are found in your urine, you have asymptomatic bacteriuria.

What are the alternative names for Asymptomatic Bacteriuria?

Screening - asymptomatic bacteria

What are the causes of Asymptomatic Bacteriuria?

Asymptomatic bacteriuria occurs in a small number of healthy people. It affects women more often than men. The reasons for the lack of symptoms are not well understood.

You are more likely to have this problem if you:

  • Have a urinary catheter in place
  • Are female
  • Are pregnant
  • Are sexually active (in females)
  • Have long-term diabetes and are female
  • Are an older adult
  • Have recently had a surgical procedure on your urinary tract
What are the symptoms of Asymptomatic Bacteriuria?

There are no symptoms of this problem.

If you have these symptoms, you may have a urinary tract infection, but you do not have asymptomatic bacteriuria.

  • Burning during urination
  • Increased urgency to urinate
  • Increased frequency of urination

What are the current treatments for Asymptomatic Bacteriuria?

Most people who have bacteria growing in their urine, but no symptoms, do not need treatment. This is because the bacteria are not causing any harm. In fact, treating people with this problem may make it harder to treat infections in the future.

However, for some people getting a urinary tract infection is more likely or may cause more severe problems. As a result, treatment with antibiotics may be needed if:

  • You are pregnant.
  • You recently had a kidney transplant.
  • You are scheduled for surgery involving the prostate gland or the bladder.
  • You have kidney stones that have caused an infection.
  • Your young child has reflux (backward movement of urine from the bladder into ureters or kidneys).

Without symptoms being present, even people who are older adults, have diabetes, or have a catheter in place do not need treatment.
