2. Causes of symptoms  Hyperplasia of epithelial and stromal components of prostate  Progressive obstruction of urinary outflow  Increased activity of detrusor muscle  Causes  Frequency, nocturia  Poor flow, intermittent stream  Hesitation, terminal dribbling

3. Prevalence  Men > 50 = 41% have symptoms of LUTS  Only 18% have a diagnosis  Only 10% aware of drugs or surgery that will help it

4. Risk factors  Age  ? obesity

5. Differential diagnosis Poorly controlled diabetes Neurological disorders Urinary tract infections Abacterial prostatitis Overactive bladder Drugs – diuretics, anticholinergics, antidepressants Lifestyle factors – caffeine, alcohol, xs fluids

6. Abnormal symptoms  The presence of the following symptoms indicates referral to urologist for futher assessment  Urinary incontinence  Retention  Dysuria  Haematuria  Acute change in symptoms

7. Examination  Palpation of abdomen for  enlarged bladder  enlarged kidneys  constipation  Rectal examination for  Size and consistency of prostate gland

8. Investigations Blood tests – Fbc esr – U&e’s – Fasting blood sugar – ? PSA – level rises with increasing volume of prostate gland Urinalysis – Infection – haematuria

9. Investigations  Additional tests as appropriate by GP  Ultrasound for residual urine volume  Urinary diaries

10. Specialist investigations  Reasons for doing them  Patient reassurance  Patient explanation  Objective assessment of symptoms  Diagnostic precision  Ranking of treatment options  Prediction of treatment outcome

11. Specialist investigations  Uroflowmetry  max flow rate and volume of residual urine after voiding – low flow rate indicates need for TURP  Bladder pressure studies  pressure measurement during filling and emptying (cystometry) gives information on over/under activity of detrusor muscle and obstruction of bladder outlet. Predicts response to treatment. Use antimuscarinics for over activity and turp for bladder outlet obstruction

12. Specialist investigations  Urinary tract imaging  Ultrasound to estimate residual urine  Urethroscopy  Visual inspection of bladder and uerethra is used in dysuria or haematuria

13. Assesment A validated questionnaire using international prostate symptom scale. Completion gives total score of 35 – 1 – 7 mild – 8 – 19moderate – 20 – 35severe Response to the quality of life questionnaire strong predictor or whether intervention is necessary

14. Scoring system – Ask 7 questions. Answers on scale 0 – 5 depending on severity of symptoms – For first 6 questions scores are Not at all = 0 < 1 in 5 = 1 < half the time= 2 About half the time = 3 > half the time = 4 Almost always= 5 – Q7 Never = 0, once = 1, 2x = 2, 3x = 3, 4x = 4, 5x = 5

15. Questions In last month how often have you 1.Had sensation of not emptying bladder completely 2.Had urge to urinated < 2 hours after previously finished 3.Found you stopped and started again several times 4.Found it difficult to postpone urination 5.Had a weak stream (compared to when aged 30) 6.Had to push or strain to begin urination 7.How many times did you get out of bed per night to urinate

16. Quality of life If you were to spend the rest of your life with your urinary condition the way it is now, how would you feel about that? – Delighted0 – Pleased1 – Mostly satisfied2 – Mixed feelings3 – Mostly dissatisfied4 – Terrible5

17. Management  Lifestyle modification  Reduce fluid intake  Stop diuretics if poss  Avoid xs night time fluid intake/caffeine /alcohol  Empty bladder before long trips/meetings

18. Management  Treat co morbid contributing conditions  Diabetes  uti

19. Management  Drug therapy  Alpha blockers  Improve bladder and prostate smooth muscle tone  More effective than 5 alpha reductase inhibitors  All work equally well  Tamsulosin and alfuzosin require no dose titration

20. Management  Drug therapy  5 alpha reductase inhibitors  Reduce prostate volume  Reduces risk of prostate cancer, increases risk of high grade disease  Combined therapy  Men with large prostate > 40g or PSA >4 or moderate to severe symptoms combined therapy will prevent 2 episodes of clinical progression per 100men over 4yrs. Much less effective for men with smaller prostates

21. Management  Drug therapy  Storage problems  Men with symptoms of urinary urgency, frequency, small, urine volumes and nocturia in the absence of serious obstructive symptoms are categorised as over active bladder  Bladder training  Biofeedback  Antimuscarinic drugs ( oxybutinin, tolteridine) alone or in combination with treatment for obstructive symptoms

22. Management  Surgery  TURP  Greatest improvement in symptoms  5% severe haemorrhage risk  Requires GA  Alternative energy sources for TURP  Ultrasound  Laser  microwave

23. Management  Surgery  Adverse effects of surgery  Loss of ejaculation  Erectile dysfunction  Retrograde ejaculation  Incontinence  Stricture formation  Urinary retention
