Urinary Tract Infections

Each year, millions of people are diagnosed with a urinary tract infection (UTI), which is an infection that occurs anywhere in the urinary tract (the kidneys, ureters, bladder, and urethra).
Common symptoms include:
  • Painful urination
  • Frequent and intense urges to urinate
  • Pain in the lower belly or back.
A healthcare provider can diagnose a urinary tract infection by using a urine test, x-ray, or an exam that looks into the bladder using a special instrument called a cystoscope. Treatment typically involves taking an antibiotic.
