Urinary Urgency / Frequency

Urinary urgency and frequency refer to the sudden, compelling need to urinate and an abnormally increased number of voidings, often resulting from bladder irritation, detrusor overactivity, or underlying urologic or neurologic conditions.

Murtagh Diagnostic Strategy

CategoryDiagnosisKey DiscriminatorCantonese Question / Finding
Probability DiagnosisOveractive bladder (OAB)Storage LUTS (urgency ± urge incontinence, frequency, nocturia) WITHOUT infection or other pathology [1][2]「你係咪突然好急、忍唔住就要去,一日去好多次?」(Do you get sudden urgency many times a day?)
UTI / Acute cystitisDysuria + frequency + urgency ± suprapubic pain; short history; cloudy/smelly urine [8]「小便赤唔赤痛?有冇臭味或者濁?」
BPH (males ≥ 50)Voiding LUTS predominant (weak stream, hesitancy, straining) + smooth enlarged prostate on DRE [4]「尿流有冇弱咗?要唔要等好耐?」+ DRE: smooth, enlarged, non-tender, median sulcus present
Serious Not To MissBladder carcinomaPainless haematuria ± frequency/urgency in older patient, smoking Hx「有冇血尿?你有冇食煙?」
Prostate carcinomaHard, irregular, nodular prostate on DRE; ↑PSADRE: hard, irregular nodule, loss of median sulcus
Pyelonephritis / upper UTIFever, flank pain, renal angle tenderness, systemic upset「有冇發燒?腰側邊有冇痛?」+ renal angle tenderness
Urinary retention (acute/chronic)Palpable distended bladder, overflow incontinencePalpable suprapubic mass = distended bladder
PitfallsUrethral / bladder stoneStorage LUTS if stone at VUJ; classic ureteric colic [9]「有冇突然間腰好痛、痛到落腹股溝?」
Interstitial cystitisChronic suprapubic pain relieved by voiding; sterile urine「小便之前個肚係咪好脹好痛,去完會好啲?」
Genitourinary TBSterile pyuria, chronic frequency/dysuria, Hx of TB contact [10]「有冇接觸過肺結核病人?有冇長期咳?」
Atrophic vaginitis (post-menopausal F)Vaginal dryness, dyspareunia, recurrent UTI「收咗經之後有冇覺得陰道乾、痕?」
MasqueradesDiabetes mellitusPolyuria/polydipsia → ↑frequency mistaken for OAB; also → neuropathic bladder [6]「有冇口渴、飲多咗水、瘦咗?」
DrugsDiuretics → polyuria; anticholinergics → retention → overflow「有冇食利尿藥或者其他新藥?」
Neurological diseaseStroke, PD, MS, spinal cord injury → neurogenic OAB [5]「有冇手腳麻痺、行路唔穩、中過風?」
DepressionNocturia/insomnia overlap; ↓function magnifies bother「心情點?有冇唔開心、做嘢冇興趣?」
Trying to Tell Me Something?Psychosocial stress / health anxietyFear of cancer; embarrassment about incontinence; relationship strain「你最擔心嘅係咪怕係癌症?呢個問題有冇影響你同屋企人嘅關係?」
