Diseases of the Prostate • BPH / LUTS / OAB / Retention • Signs and Symptoms • Medical Management • Prostate Cancer Detection
Anatomy of BPH Normal BPH Bladder Hypertrophied detrusor muscle Prostate Urethra Obstructed urinary flow Kirby RS et al. Benign prostatic hyperplasia. Health Press, 1995.
Obstructive (Voiding) Weak stream Prolonged micturition Straining Hesitancy Intermittent stream Feeling of incomplete bladder emptying Irritative (Storage) Frequency Nocturia Urgency Incontinence Symptoms Suggestive of BPH
American Urological Association Symptom Index (AUA-SI) • Incomplete bladder emptying • Frequency • Intermittency • Urgency • Weak stream • Straining • Nocturia AUA Practice Guidelines Committee. J Urol. 2003;170(2 Pt 1):530537. Barry MJ et al. J Urol. 1992;148:15491557.
Classification Mild Moderate Severe AUA-SI 0 – 7 8 – 19 20 – 35 AUA Symptom Index (AUA-SI)
Criteria to Determine Treatment • AUA Symptom Score (Quality of Life) • Elevated Post-Void Residual • UTI • Hematuria • Bladder calculus • Retention
Medical Management for Symptomatic BPH • Alpha blockers • 5 Alpha reductase inhibitors • Combination • OAB drugs • Observation
Pharmacotherapy of BPH Alpha Blockers 5ARIs • Reduce the prostate volume • Improve symptoms • Arrest the disease process • Relax smooth muscle • Improve symptoms McConnell JD et al. N Engl J Med. 2003;349:23872398.
Alpha-Blockers (Uroxatral, Flomax) • Offers symptomatic relief within days/weeks • Does not change size of prostate • Side effects • Nasal stuffiness, orthostatic hypotension • Flomax – retrograde ejaculation • Uroxatral – no retrograde ejaculatio
5 Alpha Reductase Inhibitor (Proscar, Avodart) • Slower effect on urinary symptoms than alpha blockers • Prostate size reduction • Urinary retention risk reduction
Selection Criteria • If Signs & Symptoms – Moderate to Severe (prostate size < 30-40 gms) • Alpha blocker - 2 weeks • Cystoscopy +/- Prostate Ultrasound • If Signs & Symptoms - Moderate to Severe (prostate size > 50 gms • Alpha blocker + 5 alpha reductase inhibitor
OAB Drugs • Direct action on bladder • Storage • Urgency, frequency
American Cancer Society Screening Guidelines • DRE and PSA - Annually • Age 50 – no risk factors • Age 40 - Family history of Ca – Breast or Prostate - baseline prostate ultrasound
NEJM 5/04: PSA Inaccurate as Screening Test for Prostate Cancer • 15 % of Patients with normal PSA diagnosed with Prostate Cancer • PSA – single best test for prostate cancer screening • DRE and Prostate Ultrasound to compliment PSA • TRUS Biopsy when any abnormality
Age related norms for PSA • 40-49 < 2.5 ng/ml • 50-59 < 3.5 ng/ml • 60-69 < 4.5 ng/ml • 70-79 < 6.5 ng/ml
PSA • PSA velocity - .75 ng/ ml / year PSA velocity(2-4) - .4 ng / ml / year • PSA 4-10 • % Free PSA > 20 low risk • 10 – 20 intermediate risk • < 10 high risk
What to do with an abnormal PSA? • 1. Look for a previous PSA, DRE • If DRE abnormal, proceed to Biopsy • 2. Cipro 500mg BID x 2 weeks • 3. Free and Total PSA • 4. Assess Cancer Risks for Biopsy • 5. Biopsy when in Doubt
Prostate Ultrasound Biopsies • Sextant format, local anesthesia, 10-12 biopsies • Saturation biopsies – 1 biopsy / gm • Indications for biopsies • Abnormal PSA – high risk free PSA, PSA density • Abnormal DRE • Abnormal prostate ultrasound
The Buzz: Robot Prostatectomy • Better Cancer Cure • Less Impotence, Blood loss • Higher Incontinence • Shorter Hospitalization
NEJM 4 / 08: Robot vs. Open Prostatectomy • Conclusion: No Difference • Selection determined by patient bias
