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
| Category | Diagnosis | Key Discriminator | Cantonese Question / Finding | Probability |
|---|---|---|---|---|
| Probability Diagnosis | UTI / Acute cystitis | Dysuria + frequency + urgency ± suprapubic pain; short history; cloudy/smelly urine [8] | 「小便赤唔赤痛？有冇臭味或者濁？」 | ~25% |
| Overactive 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?) | ~20% | |
| 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 | ~15% | |
| Serious Not To Miss | Pyelonephritis / upper UTI | Fever, flank pain, renal angle tenderness, systemic upset | 「有冇發燒？腰側邊有冇痛？」+ renal angle tenderness | ~5% |
| Urinary retention (acute/chronic) | Palpable distended bladder, overflow incontinence | Palpable suprapubic mass = distended bladder | ~2% | |
| Prostate carcinoma | Hard, irregular, nodular prostate on DRE; ↑PSA | DRE: hard, irregular nodule, loss of median sulcus | ~1% | |
| Bladder carcinoma | Painless haematuria ± frequency/urgency in older patient, smoking Hx | 「有冇血尿？你有冇食煙？」 | ~1% | |
| Pitfalls | Atrophic vaginitis (post-menopausal F) | Vaginal dryness, dyspareunia, recurrent UTI | 「收咗經之後有冇覺得陰道乾、痕？」 | ~10% |
| Urethral / bladder stone | Storage LUTS if stone at VUJ; classic ureteric colic [9] | 「有冇突然間腰好痛、痛到落腹股溝？」 | ~3% | |
| Interstitial cystitis | Chronic suprapubic pain relieved by voiding; sterile urine | 「小便之前個肚係咪好脹好痛，去完會好啲？」 | ~2% | |
| Genitourinary TB | Sterile pyuria, chronic frequency/dysuria, Hx of TB contact [10] | 「有冇接觸過肺結核病人？有冇長期咳？」 | < 1% | |
| Masquerades | Diabetes mellitus | Polyuria/polydipsia → ↑frequency mistaken for OAB; also → neuropathic bladder [6] | 「有冇口渴、飲多咗水、瘦咗？」 | ~10% |
| Drugs | Diuretics → polyuria; anticholinergics → retention → overflow | 「有冇食利尿藥或者其他新藥？」 | ~8% | |
| Neurological disease | Stroke, PD, MS, spinal cord injury → neurogenic OAB [5] | 「有冇手腳麻痺、行路唔穩、中過風？」 | ~3% | |
| Depression | Nocturia/insomnia overlap; ↓function magnifies bother | 「心情點？有冇唔開心、做嘢冇興趣？」 | ~2% | |
| Trying to Tell Me Something? | Psychosocial stress / health anxiety | Fear 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？」 | ~10% |
6-Minute Consultation Structure
| Time | Task | Cantonese Key Phrases | Why It Scores Marks |
|---|---|---|---|
| 0:00–0:30 | Friendly opening, rapport, set agenda | 「你好，我係XXX醫生，今日想同你傾吓你嚟睇嘅原因，方唔方便講吓？」 | Interpersonal marks: warmth, permission, patient-centred opening |
| 0:30–2:00 | Chief complaint + HPI (symptom analysis) | 「你話成日急住要去廁所，可唔可以講吓幾時開始？一日去幾多次？夜晚起身幾多次？有冇忍唔住漏咗出嚟？」 | Establishes CC accurately; covers storage + voiding LUTS systematically |
| 2:00–3:00 | Red flags + associated symptoms | 「有冇血尿？有冇痛？有冇發燒？有冇覺得瘦咗？小便有冇弱咗、要等好耐先出到？」 | Must-not-miss: malignancy, UTI, urinary retention, stones |
| 3:00–4:00 | PMHx, DHx, allergy, FHx, SHx, sexual/menstrual Hx | 「你有冇長期病？食緊乜嘢藥？有冇藥物敏感？屋企有冇人有前列腺或者膀胱嘅問題？你飲水多唔多？有冇飲咖啡茶酒？」 | Completeness marks; drug causes (anticholinergics, diuretics); social context |
| 4:00–5:00 | ICE + Hidden agenda | 「你自己覺得係咩原因？你最擔心啲乜嘢？（e.g. 癌症？）你今日嚟最想我幫到你啲乜？」 | ICE marks directly; uncovers hidden agenda ("Why today?") |
| 5:00–5:30 | Functional impact + psychosocial | 「呢個問題影唔影響你返工？瞓覺質素點？心情有冇受影響？」 | Biopsychosocial marks; functional impact |
| 5:30–6:00 | Summarise, check understanding, close | 「等我同你總結吓：你嘅主要問題係……我嘅計劃係……你有冇其他嘢想問？」 | Signposting + summarising = high interpersonal marks |
Uncovering the hidden agenda: The symptom is urgency/frequency, but the reason for consultation today may be: fear of prostate/bladder cancer, embarrassment from incontinence, sleep disruption from nocturia, or a recent trigger (e.g. saw blood in urine, friend diagnosed with cancer). Always ask: 「點解揀今日嚟睇？有冇特別嘢令你擔心？」

Case Report Form Answer Builder
- CC: Urinary urgency and frequency for [duration]
- HPI high-yield points: Onset, frequency (voids/day), nocturia (times/night), urgency (sudden, compelling, difficult to defer), ± urge incontinence, ± voiding LUTS (weak stream, hesitancy, straining, incomplete emptying), ± dysuria, haematuria, fever, fluid intake, caffeine/alcohol use, functional impact
- Examples: "Worried symptoms may indicate cancer" / "Sleep disturbed by nocturia" / "Embarrassed by leaking urine at work" / "Triggered by recent episode of haematuria"
- Phrasing tip: State the patient's actual reason for attending today, not just the symptom. Use ICE to identify this.
| Example Wording | |
|---|---|
| Ideas | "Patient thinks he may have prostate problem / bladder infection" |
| Concerns | "Worried about bladder cancer because friend was recently diagnosed" |
| Expectations | "Wants urine test and referral for further investigation / reassurance" |
- Choose based on age, gender, symptom pattern:
- Middle-aged/elderly male with both voiding + storage LUTS → BPH (smooth enlarged prostate on DRE, IPSS moderate-severe)
- Female or male with predominantly storage LUTS, no infection → Overactive bladder (OAB)
- Acute dysuria + frequency + urgency → Acute cystitis / UTI
- Minimum supporting evidence: Symptom pattern matching storage vs voiding predominance, duration (chronic vs acute), urinalysis result, DRE findings (males)
| DDx | Key Discriminator |
|---|---|
| 1. UTI / Acute cystitis | Acute onset, dysuria, cloudy/smelly urine, +ve urinalysis (leukocyte esterase, nitrites) |
| 2. BPH (if OAB is main dx) / OAB (if BPH is main dx) | Voiding LUTS predominant in BPH; storage LUTS in OAB; DRE enlarged in BPH |
| 3. Bladder carcinoma | Painless haematuria, older age, smoking history, weight loss |
| Domain | Problem |
|---|---|
| Biological | Urinary urgency/frequency causing nocturia and sleep deprivation |
| Psychological | Anxiety about possible cancer / embarrassment about incontinence |
| Social | Avoidance of social activities due to fear of leaking; impaired work productivity |
| Diagnosis/DDx | Best Supporting Physical Sign | How to Elicit | Why It Supports This Diagnosis |
|---|---|---|---|
| BPH | Smooth, symmetrically enlarged prostate > 3 finger-breadths on DRE, non-tender, median sulcus present [4] | Digital rectal examination: patient in left lateral position, lubricated gloved index finger | Enlarged prostate = benign prostatic hyperplasia causing BOO and secondary LUTS |
| OAB | No reliable physical sign in brief FM station | Best exam clue: bladder diary showing ↑frequency + low voided volumes; urodynamics showing detrusor overactivity | OAB is a clinical/urodynamic diagnosis; physical exam is largely normal |
| UTI / Cystitis | Suprapubic tenderness on palpation | Palpate suprapubic region; +ve if tender | Suggests bladder inflammation; combine with dipstick (leukocyte esterase+, nitrites+) |
| Bladder carcinoma | No reliable physical sign early | Best clue: painless haematuria on urinalysis; cystoscopy needed | Early bladder CA has no palpable sign; refer urgently if painless haematuria in ≥ 45y |
| Urinary retention | Palpable distended bladder on abdominal examination | Percuss and palpate suprapubic area; dull to percussion, firm, tender if acute | Palpable bladder = significant residual volume → overflow incontinence |
| Prostate carcinoma | Hard, irregular, nodular prostate on DRE; loss of median sulcus | DRE | Hard irregular nodule distinguishes from smooth BPH |
Top Traps That Lose Marks
- Assuming all LUTS = BPH. LUTS can occur in females; LUTS ≠ BPH [5]. Always consider OAB, UTI, bladder pathology, neurogenic causes.
- Forgetting to ask about haematuria. Painless haematuria is the key red flag for bladder/renal malignancy — if you don't ask, you can't catch it.
- Missing drug causes. Diuretics, anticholinergics, sympathomimetics, and alpha-blockers can all cause or worsen LUTS [7].
- Not asking ICE. The case report specifically marks ICE — students who skip this lose guaranteed marks.
- Confusing dysuria with LUTS. Dysuria is indicative of UTI or LUT inflammation and is NOT grouped under either storage or voiding LUTS [5].
- Not checking for diabetes. Polyuria from DM/DI mimics frequency; diabetic neuropathy causes neuropathic bladder [6].
- Forgetting sexual/menstrual history. Post-menopausal atrophic changes, genital prolapse, and STIs are common pitfalls.
Must-not-miss red flags — refer urgently:
- Painless haematuria (≥ 45y) → cystoscopy to exclude bladder CA
- Acute urinary retention (palpable bladder, unable to void) → catheterisation
- Fever + loin pain + LUTS → pyelonephritis, sepsis risk
- New neurological symptoms (leg weakness, saddle anaesthesia, bowel incontinence) → cauda equina syndrome
Shortest safe management/safety-net line: 「我會幫你驗小便，睇吓有冇感染或者血。如果之後出現發燒、血尿、完全去唔到廁所，請即刻返嚟急症室。」 (I'll check your urine for infection or blood. If you develop fever, blood in urine, or complete inability to urinate, please come back to A&E immediately.)
Key GC lecture points to remember:
- Frequency: > 7 voids in daytime [1]
- Urgency: a sudden & strong desire to void [1]
- Nocturia: waking at night once or more to void [1]
- OAB = Dry OAB vs Wet OAB; Urgency UI = involuntary loss of urine associated with urgency [1][2]
- Voiding diary is a semi-objective method of quantifying symptoms (24–72 hours) [11]
- IPSS: quantify severity (mild 1–7, moderate 8–19, severe 20–35), NOT a diagnostic tool [5]
- BPH: static component (stromal hyperplasia, DHT, 5αRI) + dynamic component (smooth muscle, α1 blockers) [4]
High Yield Summary
What to ASK: Storage LUTS (frequency, urgency, nocturia, incontinence) → Voiding LUTS (DISH) → Dysuria/haematuria/fever → Fluid intake/caffeine → Drug history → PMHx (DM, neuro) → Sexual/menstrual Hx → ICE + functional impact.
What to WRITE: CC with duration → HPI using LUTS framework → ONE main RFC (patient's real reason) → ICE verbatim → Most likely Dx with evidence → 3 DDx with discriminators → 3 biopsychosocial problems → 1 physical sign (DRE for BPH, suprapubic tenderness for UTI, palpable bladder for retention).
What NOT to MISS: Painless haematuria (cancer), fever + loin pain (pyelonephritis), acute retention (palpable bladder), drug causes, DM, neurological causes, and the hidden agenda (fear of cancer/embarrassment).

Urinary Incontinence
Involuntary loss of urine due to impaired bladder storage or sphincter function, classified as stress, urge, overflow, or functional incontinence.
Vaginal Bleeding (non-menstrual)
Non-menstrual vaginal bleeding is abnormal bleeding from the vaginal or uterine tract occurring outside of normal menses, caused by conditions such as pregnancy complications, infection, hormonal imbalances, trauma, or neoplasia.
