No circumcision

HPV

4

Glandular and stromal prostatic tissue

7
Q

What is thought to cause benign nodular hyperplasia of the prostate?

A

Hormonal imbalance

Alteration of Androgen/Oestrogen ratio

(Central (peri-urethral) gland involved – oestrogen responsive)

8
Q

Prostatism refers to which clinical symptoms?

A

Bladder hypertrophy, diverticulum formation

If untreated hydroureter, hydronephrosis, infection can occur

(it is not a pre-malignant condition)

False

14
Q

Where does carcinoma of the prostate mainly arise from?

A

Peripheral ducts and glands

(particularly posterior lobe)

A

Urethral (obstruction)

Capsular penetration

Seminal vesicles

Bladder

Rectum

16
Q

How does carcinoma of the prostate affect the bone when it metastasizes?

Osteosclerosis

(bone growth)

Para-aortic

18
Q

In which ways can carcinoma of the prostate be diagnosed?

A

Rectal exam

USS/skeletal X-rays/bone scans

Increased PSA

Biopsy (multiple biopsies)

19
Q

How is carcinoma of the prostate managed?

A

Hormonal Therapy – anti-androgen treatment

Radiotherapy – bone metastases

Surgery – Radical Prostatectomy

20
