IPPS (prostate symptom score)
Assess frequency of the following symptoms (score from 0-5)
- sense of incomplete emptying- Frequency- Intermittency- Urgency- Weak stream- Straining- nocturia

When to refer
1. High symptom score2. Abn DRE3. Palpable bladder (RU > 300ml)4. Hx of recurrent UTI / haematuria5. PSA > 46. Rapid onset of symptoms +/- low back pain7. Complications develop (impaired renal function)

Management of LUTS due to BPH
ConservativeMedical Surgical
Mild symptoms conservative (simple advice)Moderate symptoms medical treatmentSevere symptoms / surgical indication refer urologist

Conservative management
1. Adequate dietary fibre2. Avoid drugs that may precipitate urinar
y retention3. Avoid excessive water intake, coffee / te
a at night time4. Adequate voiding, double voiding
![Page 14: Approach to a man with Lower Urinary Tract Symptoms Dr. Yeung Fun Na, Fannie](https://reader035.vdocuments.net/reader035/viewer/2022062217/56649e3b5503460f94b2d8d4/html5/thumbnails/14.jpg)
Medical Treatment
1. Alpha blockers (e.g. terazosin, doxazosin)- Relax muscle at bladder neck, prostatic urethra- Effective in 60% patients ( flow PSS)- Possible SE: drowsiness, dizziness, headache 10-15%- Effective after 1-2 doses- Can be used as single agent in treating patients with HT esp usef
ul in those with dyslipidaemia2. 5 alpha-reductase inhibitor (e.g. finasteride)- Inhibit T DHT, prostate volume- Possible SE: libido, impotence 4%- Takes 3-6 months to have improvement in urine flow; less effecti
ve; more expensive

Examples of commonly used Alpha-blocker
Hytrin (terazosin HCl)- Initial dose 1mg Nocte- Titrate stepwise to 2mg, then 5mg, 10mg daily
Cardura (doxazosin HCl)- Initial dose 1mg Nocte- Titrate stepwise to 2mg, 4mg, up to 8mg with recomme
nded titration interval of 1-2 weeks- S/E: dizziness, headache
![Page 16: Approach to a man with Lower Urinary Tract Symptoms Dr. Yeung Fun Na, Fannie](https://reader035.vdocuments.net/reader035/viewer/2022062217/56649e3b5503460f94b2d8d4/html5/thumbnails/16.jpg)
Examples of commonly used Alpha-blocker
- Cardura XL- Modified release formulation of Cardura, which release
s doxazosin over 12-16 hours and provides a sustained plasma concentration throughout 24 hour dosing scheduled
- Same efficacy with Cardura- Initial dose 4mg Nocte- No need for dose titration
Xatral SR (alfuzosin HCl)- 5mg daily, up to 5mg bd

Surgical Treatment
TURP (commonest prostate operation)- possible peri-operative complications and long
term complications (like incontinence, urethral stricture, impotence, retrograde ejaculation, recurrent symptoms, prostatic re-growth)
Others:- Open prostatectomy, TUIP, thermal therapy, las
er therapy, stenting

PSA (prostatic specific antigen)
1. Organ-specific, not cancer-specific2. Normal cutoff value < 4.0 ng/ml3. with age, prostatic volume4. in 25% BPH, 80% CA5. PSA > 10 and abn DRE: 65% cancer6. Not for Routine Screening !!!
![Page 19: Approach to a man with Lower Urinary Tract Symptoms Dr. Yeung Fun Na, Fannie](https://reader035.vdocuments.net/reader035/viewer/2022062217/56649e3b5503460f94b2d8d4/html5/thumbnails/19.jpg)
Indications for PSA
1. Screening for High risk group - 1 x 1st degree: 2-5x- 2 x 1st degree: 5-10x- > 20% / year biopsy
2. life expectancy > 10 years AND requesting for PSA test / highly suspicious of CA prostate e.g. abn DRE

False Positives
Recent episodes of - UTI- Retention of urine- ProstatitisWithin 72 hours after ejaculationShortly after prostatic surgery or biopsy

Interpretation of PSA level
< 4 normal4-10 equivocal, 20% chance> 10 > 50% > 20%/yr immediate bx
Age upper limit 40-49 2.550-59 3.560-69 4.570-79 6.5
