Takeaways

  • The incidence of Staphylococcus aurea as a urinary pathogen is increasing, however, this finding may represent more than a simple urinary tract infection.
  • One review found an 8-21%rate of association between S. aureus in the urine with bacteremia.
  • Additional work up, including blood cultures, may be warranted in patients with systemic symptoms, lack of access to follow up, and no urinary tract pathology or instrumentation.

In-Depth

Risk factors associated with S. aureus bacturia include:

  • catheterization and/or invasive urologic procedures
  • Urinary obstruction
  • Malignancy
  • Long term care facility residence
  • Recent antibiotics
