Common urinary histories

Frequency / dysuria / nocturia

Exploring symptom

  • Timeframe
    • Duration
    • Onset (sudden or gradual)
    • Progression
    • Timing (intermittent or continuous)
  • Urination
    • Try to quantify urinary volume and frequency
    • Any catheter

Relevant system reviews

  • General
    • Fever, sweats, rigors
  • Urological
    • Storage: frequency, volume, urgency, nocturia, incontinence
    • Infection: dysuria, haematuria, odour
    • Prostatic/voiding (if male): hesitancy, poor flow/dribbling, feeling of incomplete emptying

Differential diagnoses and clues
