BPH pathogenesis
Multifactorial and under endocrine control otherwise unknown
2 factors essential for BPH?
Dihydrotestosterone (DHT)
Aging
DHT pathology of BPH
5-alpha-reductase converts testosterone to DHT which promotes prostate cell proliferation (hyperstatic process)
BPH growth pattern
Nodular w/ varying amounts of stroma or epithelial growth occuring in the transition zone surrounding urethra
Prostatic stroma composed of?
Smooth muscle and collagen
- adrenergic nerves
5-alpha-reductase inhibitor TXT concepts
- decreases prostate tone/outlet resistance
- responds better w/in Epithelium
prostate hyperplasia pathophysiology
Mechanical obstruction of urethra - higher bladder resistance
Efficency of DRE to eval prostate?
Poorly correlates w/ S/S
Types of S/S ass/w BPH?
Obstructive voiding - hyperplasia growth
Irritative voiding - 2/2 outlet resistance of the bladder
BPH obstructive S/S
Hesitancy/straining to void Decreased force/caliber Incomplete empyting sensation Double void Post void dribble
BPH irritative S/S
Urgency
Frequency
Nocturia
Most important tool for BPH evaluation?
American Urological Association (AUA) symptom index
-self administered 7- questionnaire
BPH Hx to R/O
Prostate cancer
UTI
Neurogenic bladder
Urethral stricture
Prostate characteristics for BPH
Smooth, firm, elastic anlargement
Indurations of prostate req?
Further W/U req to R/O cancer - PSA, TRU/S, Bx
Abd exam for BPH?
Look for bladder distension (sig S/S of obstruction)
BPH labs
UA - (R/O hematuria/infection)
PSA
BUN/creatinine (R/O obstructive - postrenal azotemia)
If AUA score is >=8 consider special tests?
Urodynamic studies
Post void residual (PVR)
BPH - Renal U/S or CT is only recommended if
Concomitant urinary tract disease BPH complications -Hematuira -UTI -CKD -Hx stones
BPH obstructive DDx
Urethral stricture Bladder neck contracture Bladder stones Prostate cancer Other DDX - (UTI, Bladder cancer, nuerogenic bladder)
BPH - TXT options for AUA 0-7 (mild S/S)
Observation
-progression uncertain; possible spon resolve possible
F/U interval not defined
BPH - TXT options for AUA >8 (mod-severe S/S)
Observe
Surgery
Medical therapy
BPH - Absolute surgical indications*
Refrac UA retention (failing cath removal) LRG bladder diverticula BPH sequelae of - Recurrent UTI - Recurrent/persistent gross hematuria - Bladder stones - CKD (renal insufficiency/failure)*
BPH - Rx
Alpha blockers
- Prazosin
- Doxazosin
- Terazosin
Alpha-1a blockers (selective w/ fewer SEs)
- Tamsulosin
- Alfuzosin
BPH - 5-alpha-reductase inhibitors MOA
Blocks conversion of testosterone to DHT
5-alpha-reductase inhibitors use is best for?
Enlarged prostates >40mL on U/S - will have symptomatic* improvement
Durations req for 5-alpha-reductase inhibitors - BPH TXT
6mos for max efx
5-alpha-reductase inhibitors Rx’s?
Finasteride
Dutasteride
Finasteride - important concept to consider w/ BPH?
Will reduce PSA by 50%
- If pt takes Finasteride double PSA results and compare to pre-finasteride PSA levels
(Improve or same or Worse?)
BPH combination therapies?
Alpha blocker + 5-alpha-reductase inhibitor
(Doxazosin + finasteride)
Safe/effective
Other BPH Rx therapy?
PDE-5 inhibitors

TUEV - transurethral electrovaporization of prostate
Microwave hyperthermia (burn)
Implant to open prostatic urethra
BPH conventional surgery?
TURP - transurethral resection of prostate
- most performed endoscopically
- req spinal anesthesia
- 1-2d hospital stay
Superior flow/symptom improvement vs minimal invasive therapy
If inable to perform TURP endoscopically then reflex?
TUIP - transurethral incision of prostate OR
Open simple prostatectomy - (too large to remove)
Other off-label TXTs of BPH?

Abnl PE but normal PSA level pts should be?
Referred for U/S and Bx
TRU/S guided Bx performed if?
Following ABNL DRE or elevated PSA - Definitive Dx

PSA velocity notes
serial PSA values (better than random PSA)
- may increase specificity for cancer detection
- rate of PSA change >0/75ng/mL per yr = higher risk cancer
PSA density is? and results?
Free PSA/Total PSA
- > 25% free PSA > cancer unlikely
- <10% free PSA > 50% chance of cancer
