Table 80.2

Focused Assessment of the Patient with Suspected Urinary Tract Infection

History
  • Major symptoms and time course – differentiate between lower urinary tract symptoms, upper tract symptoms and systemic features
  • Previous history of urinary tract infections
  • Antibiotic history
  • Presence/absence of urinary catheter, recent catheterization, blocked catheter, catheter change
  • History of recent urinary tract intervention or urological intervention
  • Previous history of renal tract pathology such as chronic kidney disease, renal stones, single kidney, structural abnormality
  • Pregnancy?
  • Diabetes?
  • Sexual history
  • If primarily urethritis or penile discharge, consider sexually transmitted infections (Neiserria gonorrhoea, Chlamydia trachomatis, Herpes simplex, Trichomonas vaginalis)
  • Symptoms of sexually transmitted infections and epididymo-orchitis?
  • Review any recent GP or hospital microbiology results
  • Consider points relevant to differential diagnosis – gastrointestinal symptoms

Examination

  • Vital signs and key observations if critically ill and resuscitate as appropriate
  • Assessment of presence/absence of loin tenderness
  • Presence or absence of catheter and quality of catheter urine
  • Consider alternative source of sepsis

Note: Gram-negative sepsis secondary to a urinary focus can masquerade as suspected acute respiratory tract infection in the elderly and is often misdiagnosed as such at the time of acute admission.
