Urinary Tract Infection

A urinary tract infection (UTI) occurs when bacteria enter the urethra, multiply in the urinary tract, and cause an infection. The urinary tract is made up of the kidneys, ureters, bladder, and urethra.

The infection is characterized by the part of the urinary tract that is affected. A lower UTI involves the urethra and bladder, and an upper UTI affects the ureters and kidneys. Cystitis is an infection of the bladder. Urethritis is an infection of the urethra, and pyelonephritis is an infection of the kidneys.

Symptoms of Urinary Tract Infection

The symptoms of urinary tract infection depend upon which type of infection and which part of the urinary tract is infected.

Lower UTI:

  • Blood in the urine
  • Cloudy urine
  • Inability to urinate
  • Back pain
  • Fever
  • Frequent urination
  • Painful urination
  • General discomfort

Upper UTI:

  • Chills and high fever
  • Nausea
  • Pain below the ribs

  • Pregnancy
  • Sexual activity

  • Medical conditions such as diabetes

Diagnosis and Treatment of Urinary Tract Infection

To diagnose a UTI, the following tests may be given:

  • Urine culture: testing a urine sample for signs of bacterial infection
  • Urinalysis: testing a urine sample to check for blood in the urine

Urinary tract infections are treated with a course of antibiotics. Finish the entire course of medication, even if you feel better, so the infection does not recur.
