Objectives • Define ‘LUTS’ • Causes of LUTS • Initial assessment and management • Not covered – Mx of acute retention – Stress incontinence – Prostate Ca

•

A 79 year-old man complains of LUTS. Which one of the following regarding BPH is incorrect? 1. Goserelin is licensed for refractory cases 2. Side effects of 5α-reductase inhibitors include ejaculation disorders and gynaecomastia 3. Possible presentation include recurrent UTI 4. 5α-reductase inhibitors typically decrease the PSA 5. More common in black men.

LUTS: definition • Storage (irritative) symptoms: – Urgency – Urinary frequency – Nocturia – Urinary incontinence

• Voiding (obstructive) symptoms – Hesitancy, poor stream, terminal dribbling

Causes of LUTS • Obstructive – BPH – Prostate/bladder/rectal cancer – Bladder neck/urethral strictures – Antimuscarinic drugs – Autonomic neuropathy/neurogenic bladder

Causes of LUTS • Irritative – BPH – Bladder/prostate cancer – Infection – Bladder stones – Neurological • Dementia • Diabetes • Stroke

Assessment • History – type of LUTS, duration of Sx, how bothersome are they? • Examination – abdomen (distended bladder), external genitalia, DRE • International Prostate Symptom Score: – Used to assess severity of symptoms – Score of 0-5 for seven symptoms (total 35): • 0-7 – mildly symptomatic • 8-19 – moderately symptomatic • 20-35 – severely symptomatic

•

A 62 year-old man presents with nocturia, hesitancy and terminal dribbling. DRE reveals a moderately enlarged prostate with no irregular features. PSA1.3 What is the most appropriate mx? 1. 2. 3. 4. 5.

Alpha antagonist 5-alpha reductase inhibitor Non-urgent referral for TURP Empirical tx with cipro for 2 weeks Urgent referral to urology.

•

A patient is started on finasteride for the management of BPH. How long should the patients be told that treatment may take to be effective? 1. 2. 3. 4. 5.

Within 8hrs of taking the tablet Within 3 days Up to 7 days Up to 4 weeks Up to 6 months

Management • Urine dip +/- culture • U&E – Chronic retention – Recurrent UTI – Hx of renal stones

• PSA • Urinary frequency-volume chart – Ask patient to note down when they drink fluid/pass water and to comment on type of fluid – Allows to differentiate between frequency of urine, polyuria and nocturia

• Obstructive symptoms – Lifestyle changes. – Alpha blocker: e.g tamsulosin – 5α – reductase inhibitors

• Irritative symptoms – Exclude/manage treatable causes – Urine containment devices – Supervised bladder retraining – Anticholinergics e.g oxybutinin
