Urinary Tract Infection, Complicated (UTI)

Michael Melia, M.D.

PATHOGENS

Among the most common infections encountered in hospital and clinical practice, resistant strains are increasingly encountered:
- Enterobacterales
- Pseudomonas aeruginosa
- Acinetobacter sp.
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.
- Enterococcus spp. (including VRE)
- Candida spp.
- Fastidious organisms are possible.
Infections may be polymicrobial, especially if chronic urinary catheters or stents are present.
