Urinary Tract Infection, Complicated (UTI)

Michael Melia, M.D.


  • Among the most common infections encountered in hospital and clinical practice, resistant strains are increasingly encountered:
  • Less common:
    • MSSA or MRSA
      • Most due to invasion of the urinary tract (secondary to catheters, stents)
      • Consider presentations of staphylococcal bacteremia with findings of S. aureus in urine.
  • Infections may be polymicrobial, especially if chronic urinary catheters or stents are present.
