Enlarged Prostate
What is Enlarged Prostate?
• Enlargement of the prostate is usually caused by hyperplasia (BPH), carcinoma (Ca - prostate ) and inflammation (prostatitis).
• Enlarged Prostate is commonest conditions affecting older men, which can lead to LUTS
• Advancing age and testicular androgens play a central role in enlargement.
Prostate : Revisiting Anatomy
Prostatic Smooth Muscles are provided with alpha 1 receptors predominant A1 subtype.
Prostate : Revisiting Physiology
Prostate & Testosterone
o The primary androgenic stimulator of prostate growth is Dihydrotestosterone (DHT)
o DHT is produced from testosterone via the 5-alpha-reductase (5-AR) isoenzymes type I & II
Prostate : Revisiting Physiology
Functions of Prostate: o Secretory functions:
o Forms 70% of seminal fluid , alkaline for neutralizing acidic vaginal environment. o Provide carbohydrates and nutrient to sperms.
o Sphincteric Functions: o Part of internal urethral sphincter mechanism. o Close bladder outlet during ejaculation to divert semen to exterior..
o Ejaculatory Function:
o Smooth rhythmic contraction of prostatic smooth muscles in co ordination with smooth muscle of vas deference, seminal vesicle, ejaculatory duct and the Ischiocavernosus and balbocavernosusu muscles.
Lower Urinary Tract Symptoms (LUTS)
OBSTRUCTIVE / VOIDING SYMPTOMS
IRRITATIVE / STORAGE SYMPTOMS
ASSOCIATED SYMPTOMS
POST MICTURITION SYMPTOMS
LUTS: Irritative / Storage Symptoms
o Frequency
o Urgency
o Nocturia
o incontinence
Irritative Symptoms
LUTS : Obstructive/Voiding Symptoms
o Hesitancy o Straining o Weak urinary stream o Intermittency o Prolonged voiding o Terminal dribbling o Incomplete bladder emptying o Obstruction/incontinance
Obstructive / Voiding Symptoms
LUTS : Post Micturition Symptoms
o Incomplete bladder emptying
o Post Micturition Dribbling

BPH: Surgical Treatment
Indications for surgery
• Absolute
o Recurrent urinary retention o Recurrent urinary tract infections o Recurrent hematuria that cannot be controlled
conservatively o Bladder calculi o Dilatation of upper urinary tract/renal failure owing
to BPH-related bladder outlet obstruction
BPH: Surgical Treatment
Indications for surgery • Relative
o Relevant BPH-related bladder outlet obstruction o Bladder diverticles o No success with conservative or alternative
therapies (for example, in unchanged or increasing symptoms or obstruction)
o Allergies or contraindications for conservative therapies
o Postvoid residual urine >100 ml
BPH: Surgical Treatment
Surgical Procedures for BPH :
o Transurethral Incision of Prostate (TUIP)
o Transurethral Resection of Prostate (TURP)
o Retro Pubic Prostatectomy
o Trans Vesical Prostatectomy (TVP)
Enlarged Prostate : Ca Prostate
Prostate cancer: clinical presentation
o Localized prostate cancer o Asymptomatic, with screening serum PSA or
incidental DRE. o Lower urinary tract symptoms (probably coexisting
BPH) o Haematospermia o Haematuria (probably due to coexisting benign
hyperplasia) o Perineal discomfort (probably due to coexisting
prostatitis)
Enlarged Prostate : Ca Prostate
Prostate cancer: clinical presentation
o Locally advanced cancer o Asymptomatic, with screening serum PSA or incidental DRE o Lower urinary tract symptoms o Haematospermia o Haematuria o Perineal discomfort o Symptoms of renal failure/anuria due to ureteric obstruction o Malignant priapism (rare) o Rectal obstruction (rare)
Enlarged Prostate : Ca Prostate
Prostate cancer: clinical presentation
o Metastatic disease (N+, M+) o Asymptomatic, with screening serum PSA or incidental DRE o Swelling of lower limb due to lymphatic obstruction o Anorexia, weight loss o Bone pain, pathological fracture o Neurological symptoms/signs in lower limbs (spinal cord compression) o Anaemia o Dyspnoea, jaundice, bleeding tendency (coagulopathy)
Enlarged Prostate : Ca Prostate
Prostate cancer: Treatment Localized prostate cancer
o Watchful waiting o Radical Prostatectomy
o Management of biochemical relapse post-RP o Radiotherapy o Hormonal Treatment
o Radical External Beam Radiotherapy (EBRT) o Brachytherapy (BT) o Cryotherapy o High-intensity focused ultrasound (HIFU)
Enlarged Prostate : Ca Prostate
Prostate Cancer: Treatment o Management of locally advanced non-
metastatic prostate cancer (T3â4 N0M0) o EBRT o Hormone therapy o Watchful waiting o Palliative treatment of locally advanced
disease
Enlarged Prostate : Ca Prostate
Prostate Cancer : Treatment o Management of advanced prostate cancer:
o Hormone therapy o Cytotoxic chemotherapy o OTHER Developing treatment
o growth factor inhibitors, o angiogenesis inhibitors, o immunotherapy, and o gene therapy
Enlarged Prostate : Ca Prostate
Prostate Cancer : Treatment o Mechanism of Androgen Deprivation.
o Surgical castration: bilateral orchidectomy o Medical castration: luteinizing hormone-releasing
hormone (LH-RH) agonists, oestrogens; also termed androgen ablation or androgen deprivation
o Anti-androgens (steroidal or non-steroidal): androgen receptor blockade at target cell
o Maximal androgen blockade (MAB): Surgical castration plus anti-androgen
o 5 Alpha 1 Reductase inhibition (5ARI) with finasteride or dutasteride.
