Prevalence • 2007 study: enlarged prostate = 4th most

common diagnosis in men over 50.

• Approximately 1/3 of men over 50 have moderate to severe LUTS

• i.e. ~ 3 million men in UK

LUTS 8

• Huge issue = men reporting symptoms at all

• Some can be rather stoical: “just part of growing old”

Presentation: what do patients say?

LUTS 9

• “I’m worried about me prostrate”

• “While I’m here doc…”


Lack of

physical

intimacy

LUTS 32

LUTS Assessment: Investigations

• Urine dipstick test

• Bloods:

– “Offer a serum creatinine test only if you suspect renal impairment”

– PSA?

LUTS 34


• “Ask men with bothersome LUTS to complete a urinary frequency volume chart.”

• “Offer men considering treatment an assessment of baseline symptoms with a validated symptom score (e.g. IPSS).”

LUTS 35 LUTS 36


• What’s normal?

• Void: ~300-500ml

• Fluid in: ~1.5-2L / 24 hrs

• Urine out: ~1.5-2L / 24 hrs

– 30ml/kg / 24hrs

• Frequency: > 8 voids/ 24hrs

• Nocturia: as > 1 void at night

• (Nocturnal polyuria: >⅓ volume at night)

LUTS 37


• Small volume voids with variation in voided volume – characteristic of OAB

• Small volume voids without significant variation in voided volume:

• Interest in sex declines with worsening LUTS

• Prostate disease 2nd only to DM as ED risk factor:

– more than PVD, hyperlipidaemia, HT, depression, IHD

• Unclear how much association is physiological, or related to sleep disturbance/anxiety

• Primary Care = ideal setting for holistic management of male LUTS

• The prostate as the “gateway to men’s health”

LUTS 50

LUTS Management

Uncomplicated LUTS Complicated LUTS

• Gradual onset

• Impalpable bladder

• Normal external genitalia

• Benign feeling prostate

• Normal PSA

• No infection / haematuria

• Raised PSA / Abnormal DRE

• Pelvic / Urogenital pain

• Recurrent UTI / Dysuria

• Palpable bladder

• Incontinence

• Haematuria

• Severe symptoms

• Bladder stones!

LUTS 51

LUTS Management • If LUTS not bothersome or complicated, reassure

Cancer worry:

• For most cases, NO strong link between onset of LUTS & onset of prostate cancer

LUTS 52

LUTS Management

• Think possible causes (PMH/Meds)

• Offer:

–advice on lifestyle interventions (e.g. fluid intake, caffeine, smoking, time of diuretics)

–information on the condition

LUTS 53 LUTS 54

LUTS Management - Conservative

• If you suspect OAB, offer:

– supervised bladder training

– if needed, containment products.

LUTS 55


• If you suspect OAB, offer:

– supervised bladder training

– if needed, containment products.

• Do not offer penile clamps

LUTS 56


• For men with post-micturition dribble, advise how to perform urethral milking:

LUTS 57

LUTS Management – Drug Rx

• Offer only if bothersome LUTS, & conservative management unsuccessful or not appropriate.

• Do not offer homeopathy, phytotherapy or acupuncture.

LUTS 58


• Overactive bladder:

–Offer an anticholinergic

LUTS 59


• Overactive bladder:

–Mirabegron (Betmiga), 50mg od

–β3-adrenoceptor agonist

• NICE: only if anticholinergic is ineffective, contraindicated or not tolerated

LUTS 60

LUTS Management – Drug Rx 1. Moderate to severe LUTS (not OAB predominant):

–Offer an α-blocker

2. LUTS with PSA >1.4, prostate >30g:

- high risk of progression:

–Offer a 5-α reductase inhibitor (5-ARI)

If 1 and 2:

–Offer combination treatment

LUTS 61

• Progression =

– Worsening symptoms

– Acute retention

– BPH-related surgery

Risk factors:

– Age over 70

– Moderate to severe bothersome symptoms

– PSA > 1.4 ng/ml, Prostate volume >30ml

LUTS 63

LUTS Management: α-blockers

• Reduce tone of bladder neck / prostate

• Ideal first line in primary care for ‘mixed LUTS’

• Rapid onset 4-6 weeks

• No effect on PSA level or prostate size

LUTS 64

LUTS Management: α-blockers

• BUT: do not prevent progression

• S/E include: dizzy, faint, weak, bowel effects, headache, ejaculatory dysfunction …

LUTS 65

LUTS Management: 5-ARIs

• Inhibit conversion of T to DHT

• ↓prostate volume

• Most effective in larger prostates

LUTS 66

LUTS Management: 5-ARIs

• Beneficial effects start at 6-9 months, fully develop over years

• ↓symptoms & ↓rate of retention / surgery

• S/E include: fatigue, ED, ↓ libido, gynaecomastia

LUTS 67

LUTS Management: 5-ARIs & PSA

• Any confirmed increase from lowest PSA level may signal non-compliance to therapy, or prostate cancer (particularly high-grade)

– should be carefully evaluated

• Can still use PSA to help risk assessment of PCa, after a new baseline established

LUTS 68

LUTS Management: Combination

05/12/2016

12

LUTS 69

LUTS Management: Combination

• Studies show combination Rx:

–Most effective for controlling symptoms

–Most effective for reducing progression

• e.g. At 4 years, combination vs tamsulosin alone: ↓ risk of acute retention / surgery by 70%

• 7.7% actual risk reduction (NNT=13)

2012:

Cialis (tadalafil) 5 mg od: Licensed for treating the “signs & symptoms of BPH”

SLS restrictions amended, so can prescribe for condition other than ED

LUTS 74


Tadalafil for LUTS:

• IPSS scores do improve

• NICE 2015: Do not offer solely for LUTS, unless part of a trial

LUTS 78

LUTS Management – Drug Rx Back to NICE:

• Consider adding an anticholinergic if storage symptoms after α–blocker for LUTS

• LOW risk of retention

LUTS 79

LUTS Management – Drug Rx Back to NICE:

• Nocturnal polyuria (>1/3 urine at night):

– Consider late-afternoon loop diuretic

– Consider desmopressin, if other medical causes have been excluded

LUTS 80

LUTS: Referral

• Bothersome LUTS not responded to conservative & drug management

• Complicated LUTS

• HoLEP (laser)

• ‘Urolift’ for some

– Relieves LUTS while avoiding risk to sexual function

LUTS 87

LUTS: SUMMARY

• Common, under-reported

• Ask: what is bothering the patient?

• Strong link with ED / Metabolic Syndrome

• Holistic assessment

• Think: balls

LUTS 88

LUTS: SUMMARY

• Lifestyle intervention especially fluid intake

• Medical therapy according to symptoms

• Find & treat nocturnal polyuria

• Remember: a progressive condition

• Refer if not responding / atypical / complicated
