BPH Flashcards
Pathology
Anatomical vs dynamic
Anatomical: true hyperplasia of cells, 🔼 in epithelial content
Dynamic: 🔼 fibromuscular stroma, tone of smooth muscle fibers in prostate under adrenergic control changes
Prostate ca= peripheral zone
BPH= transitional zone
LUTS name 11 constituents
Obstructive
Hesitancy, poor stream, intermittency,
post micturition dribbling, incomplete
voiding and straining
Irritative
Nocturia x3, frequency, urgency, urge
incontinence
Other causes for LUTs other than BPH
Ca of prostate Urethral stricture Bladder neck contracture Neurogenic bladder dysfunction Diabetes
Treatment of BPH
Watchful waiting
Medical mx (for symptomatic BPH without complications)
Alpha adrenergic blockers tamusalin/flomax
decrease dynamic obstruction therefore relaxing
prostatic smooth muscle (best for small prostate)
Causes vasodilation, hypotension, dizzy and
syncope
5 alpha reductase inhib (causes shrinkage of prostate by blocking testosterone into DHT) Large prostates and decrease PSA= finesteride
Surgery
Indications for surgery
Complications of bladder outflow obstruction (recurrent UTI, hydroneohrosis)
Recurrent haematuria
Previous prostate surgery
Failed medical mx
Complications of TURP
TUR syndrome Secondary hemorrhage Septicemia Retrograde ejaculation Incontinence Urethral stricture
Etiology
Age >40 (70% of 70 year olds have BPH)
Hormones: androgens, oestrogen and prolactin, DHT
Racial/ dietary factors
Epithelial stromal interaction:
