Why no prostate?

The Role of Testosterone
Skin
Hair growth,
sebum production
Brain
Libido, Mood
Liver
Synthesis of
serum proteins
Muscle
Increase in strength
and volume
Bone
Accelerated linear
growth, closure of
epiphyses
Male sexual organs
Penile growth,
spermatogenesis,
prostate growth and
function
Kidney
Stimulation of
erythropoietin
production
Bone marrow
Stimulation of
stem cells

What goes wrong
with the Prostate ?
• Enlarges: Benign Prostate Enlargement
• (Inflames: Prostatitis)
• Develops cancer: Prostate Carcinoma

Benign Prostate Enlargement
BPE
• Nearly all men → in fact no ‘disease’
• Occurs in transition zone (TZ)
→ peripheral zone is compressed
→ urethra can be narrowed
• Can remain asymptomatic, even in very large
glands, or be pretty symptomatic in small ones
BPE
Symptoms : Poor stream
Normal voiding
Obstructive voiding
Symptoms : Prostatism

Treatment of BPE
Indications
1. Patient- Indication: Complaints
2. Doctor’s-Indication: Acute or chronic retention
Infection
Bladder stones
Bleeding
First Medical treatment, is highly effective
Surgery if drugs not efficient
Medical treatment of BPE
= Highly effective and well tolerated
1. Phyto-therapy - good symptomatic relief
2. Alpha-blockers - bladder neck relaxation
3. 5α
α reductase inhibitors - volume decrease
4. Combinations
5. PD-5 Inhibitors
And,…when drugs fail?
Surgical Treatment of BPE
Trans-urethral resection = “TURP”

• Enlarges: Benign Prostate Enlargement
• (Inflames: Prostatitis)
• Develops cancer: Prostate Carcinoma

Prostate Cancer Symptoms
• Early PrCa is asymptomatic !
• Presence of symptoms suggest
– Locally advanced disease
– Metastases : bone pain, spinal cord compression

PSA for Early Detection?
PSA Screening
• More tumors detected
!
- risk of overtreatment
• Stage migration
!
• Mortality decrease

Prostate Cancer Mortality
Management Options ?
• Active Surveillance : wait and eventually treat
• Rad.Prostatectomy : open, laparoscopic or robot
• Irradiation: - external ( EBRT, IMRT, IGRT…)
- interstitial ( brachy - implant…)
• Other : - Cryotherapie
- HIFU
