Discussion
Pathophysiology
BPH is the most common benign tumor in males
Characterized by hyperplasia of prostatic stromal and epithelial cells, resulting in the formation of large, fairly discrete nodules in the periurethral region (transition zone) of the prostate
It is believed that the main component of the “hyperplastic” process is impaired cell death
Overall reduction of the rate of cell death, resulting in the accumulation of senescent cells in the prostate
The main androgen in the prostate, constituting 90% of total prostatic androgens, is dihydrotestosterone (DHT)
Dihydrotestosterone (DHT)
Formed in the prostate from the conversion of testosterone by the enzyme type 2 5α-reductase
Located almost entirely in stromal cells epithelial cells of the prostate do not
contain type 2 5α reductase, with the exception of a few basal cells
stromal cells are responsible for androgen-dependent prostatic growth
DHT is more potent androgen than testosterone higher affinity for androgen receptor
(AR) Binding of DHT to AR activates the
transcription of androgen-dependent genes
DHT is not a direct mitogen for prostate cells DHT-mediated transcription of genes
results in the increased production of several growth factors and their receptors
fibroblast growth factor (FGF) family, and particularly FGF-7 (keratinocyte growth factor)
FGF-7, produced by stromal cells, is probably the most important factor mediating the paracrine regulation of androgen-stimulated prostatic growth. Other growth factors produced in BPH are FGFs 1 and 2, and TGFβ, which promote fibroblast proliferation.
Clinical Findings
Obstructive Symptoms Hesitancy Decreased force and caliber of stream Sensation of incomplete bladder
emptying Double voiding Straining to urinate Postvoid dribling
Irritative Symptoms▪ secondary response of the bladder to the
increased outlet resistance Urgency Frequency Nocturia
Diagnostic Tests
Digital Rectal Exam Smooth, firm, elastic enlargement of the
prostate Urinalysis Serum Creatinine Postvoid Residual Urine Ultrasound Urethrocystoscopy
Treatment
American Urological Association Symptom Index for BPH
mild (0 to 7), moderate (8 to 19), or severe (20 to 35)
Management
Watchful Waiting Medical Therapy
α- Blockers 5α- Reductase Inhibitors Combination Therapy Phytotherapy
Conventional Surgical Therapy Transurethral resection of the Prostate ( TURP) Transurethral Incision of the Prostate Open Simple Prostatectomy
Minimally Invasive Therapy Laser Therapy (TULIP) Transurethral Needle Ablation of the Prostate
(TUNA) Transurethral Electrovaporization of the
Prostate

Pharmacologic AgentFinasteride (5α- Reductase Inhibitor)
Finasteride
Finasteride
Steroid like 5-alpha reductase inhibitor which interfere with the effect of certain male hormones (androgens) on the prostate.
Blocks the conversion of testosterone to DHT
Causes reduction in DHT levels that begins within 8 hours after administration and lasts for about 24 hours.
Absorption: Absorbed from the GI tract (oral); peak plasma concentrations after 1-2 hr.
Distribution: Protein-binding: 90%.Metabolism: Hepatic.Excretion: Urine and feces (as
metabolites); <60 yr: 6 hr; >70 yr: 8 hr (elimination half-life)
Effect of Finasteride in decreasing the size of the prostate can be seen only if patient continues to take the medication for at least 6 months.
Contraindications
Hypersensitivity to one of its components
Pregnancy Hypertension
If patient is hypertensive it is best to useα- Blockers ( Tamzolasin, Alfazosin )
Special Precautions
Undiagnosed Prostate Cancer Finasteride lowers Serum PSA levels
masking the diagnosis of Prostate CA Liver Dysfunction
It is extensively metabolized in the liver Obstructive Uropathy
Adverse Effects
Impotence - (1.1 -18.5%) Abnormal Ejaculation – (7.2%) Decreased Ejaculatory Volume –
( 0.9-2.8%) Abnormal Sexual Function – ( 2.5%) Gynecomastia – (2.2%) Erectile Dysfunction – ( 1.3%) Ejaculatory Disorder – (1.2%) Testicular Pain
