Diagnosis

Benign Prostate Hyperplasia

Pembahasan

Prostate

Walnut-shaped gland that forms part of the male reproductive systemSurrounds the urethra - the tube that carries urine from the bladder out of the body

n

n

Secretes semen which carries sperm

During orgasm, prostate muscles contract and propel ejaculate out of the penis

Prostate

n

n

The size of prostate enlarged microscopically since the age of 40.Half of all men over the age of 60 will develop an enlarged prostate

By the time men reach their 70’s and 80’s, 80% will experience urinary symptoms

But only 25% of men aged 80 will be receiving BPH treatment

Benign Prostatic Hyperplasia

Normal Prostate Anatomy• Prostate weights ~20g

• Measures 3 x 4 x 2 cm (walnut sized)

• Apex = inferior portion of prostate, continuous with striated sphincter.

• Base = superior portion and continuous with bladder neck.

PROSTATE histology

Prostatic tissue is formed of two components :•fibromuscular tissue (30%)

•glandular epithelial cells (70%)

Normal histology of the prostate formed of glands and stroma glands: lined by two layers of cells which are inner cuboidal cells and outer basal cells stroma :fibro muscular stroma

Prostate zonesCentral zone (CZ) •Cone shaped region that surround the ejaculatory ducts (extends from bladder base to the verumontanum) •Only 1-5% of prostate cancer from this region . Peripheral zone (PZ) •Posteriolateral prostate •Majority of prostatic glandular tissue •Origin of up to 70% of prostate adenocarcinoma

Transitional zone (TZ) •Surrounds the prostatic urethra •Commonest site for benign prostatic hyperplasia.

What causes BPH?

BPH is part of the natural aging process, like getting gray hair or wearing glasses

BPH cannot be prevented

BPH can be treated

Half of all men over the age of 60 will develop an enlarged prostate.

By the time men reach their 70’s and 80’s, 80% will experience urinary symptomsBut only 25% of men aged 80 will be receiving BPH treatment

BPHProposed Etiologies

• 1-alterations in the testosterone/estrogen balance:enlarged prostate may be caused by lower levels of testosterone (male hormone) production in middle to old age. As men age, the levels of testosterone in their blood decreases, leaving a higher proportion of estrogen (female hormone), so a higher amount of estrogen within the prostate gland can increase activity that promotes cell growth.

•2-Induction of prostatic growth factors.

•3- Increased stem cells/decreased stromal cell death

BENIGN PROSTATIC HYPERTROPHY (BPH)—PATHOPHYSIOLOGY

• Common in older men; varies from mild to severe• Change is actually hyperplasia of prostate

– Nodules form around urethra• Not change to cancer prostate.• Rectal exams reveals enlarged gland• Incomplete emptying of bladder leads to infections• Continued obstruction leads to distended bladder,

dilated ureters, renal damage– If significant, surgery required

WHAT’S LOWER URINARY TRACT SYMPTOMS SECONDARY TO PROSTATIC URETHRA OBSTRUCTION?Abnormal Voiding

(obstructive)symptoms• Hesitancy• Weak stream• Straining to pass urine• Prolonged micturition• Feeling of incomplete

bladder emptying• Urinary retention

Storage (irritative orfilling) symptoms•Urgency:an increasingly strong desire to void)

•Frequency•Nocturia•Urge incontinence

LUTS is not specific to BPH – not everyone withLUTS is not specific to BPH – not everyone withLUTS has BPH and not everyone with BPH has LUTSLUTS has BPH and not everyone with BPH has LUTS

BPH—SIGNS AND SYMPTOMS

• Initial signs– Obstruction of urine flow

• Hesitancy : delay between trying to urinate and the flow actually beginning.

• dribbling • decreased force of urine stream• Incomplete bladder emptying

– Frequency,– nocturia : need to urinate at night – recurrent Urinary Tract Infections

BPH complications

• hypertrophy of the prostateàdetrussor muscle of the bladder undergo hypertrophy to overcome the obstruction in the prostatic urethra. Later on decompensation occur .

•Increase pressure inside bladder diverticula formation

increasing urine retention hydronephrosis renal failure.

Diverticula in bladder

Diagnosis of BPH• Symptom assessmentSymptom assessment

• Digital rectal examination(DRE)Digital rectal examination(DRE)–inaccurate for size but can detect shape and consistency

• Prostate Volume (PV) determination by ultrasonographyProstate Volume (PV) determination by ultrasonography

• Urodynamic analysisUrodynamic analysis

• Measurement of prostate-specific antigen (PSA) Measurement of prostate-specific antigen (PSA) –high correlation between PSA and PV,–men with larger prostates have higher PSA levels–PSA is a predictor of disease progression and screening tool for Cancer Prostate.–as PSA values tend to increase with increasing Prostatic Volume and increasing age, PSA may be used as a prognostic marker for BPH.

When should BPH be treated?

BPH needs to be treated ONLy IF:

Symptoms are severe enough to bother the patient and affect his quality of life

Complications related to BPH n

n

Medication :α blockers - relax the smooth muscle of prostate

and provide a larger urethral opening

Surgical approaches

1- Transurethral resection of the prostate (TURP)

2- Open simple prostatectomy

Treatment options

“WATCHFUL WAITING”

For mild symptoms. follow up1 to 2 times yearly

Offer suggestions that help reduce symptoms

Avoid caffeine and alcoholAvoid decongestants and antihistamines

MedicationFirst line of defense against bothersome urinary symptoms

Two major types:α blockers - relax the smooth muscle of prostate and provide a larger urethral opening (Hytrin,Doxaben, Harnalidge)

5 α reductase inhibitor - Shrink the prostate gland (Proscar, Avodart)

Α-ADRENERGIC BLOCKERS: RATIONALE

• Prostate smooth muscle tone is mediated via α1-adrenergic receptor

• Blockage of the receptor leads to improvement of flow rate and LUTS1

• Central α-receptors and the effect of agents on these receptors likely play an additional role

• Density of adrenergic receptors changes with prostate size and age

•Three α1-adrenergic receptor subtypes have been identified (A, B, D)

Schwinn DA. BJU Int. 2000;86(suppl 2):11-22.

Α-BLOCKERS• Nonselective

– Phenoxybenzamine• Short-acting selective α1-blocker

– Prazosin, Alfuzosin• Long-acting selective α1-blockers

– Terazosin– Doxazosin

• Long-acting selective α1A-subtype– Tamsulosin– Alfuzosin-SR

Indication of surgical intervention • Acute urinary retention • Gross hematuria• Frequent urinary tract infection (UTI)• Vesical stone • BPH related hydronephrosis or renal

function deterioration• Obstruction

Differential Diagnosisof BPH(i.e from other causes of urinary obstruction)

• Urethral stricture• Bladder neck contracture• Carcinoma of the prostate• Carcinoma of the bladder• Bladder calculi• Urinary tract infection and prostatitis• Neurogenic bladder

TURP

“Gold Standard” of care for BPH

Uses an electrical “knife” to surgically cut and remove excess prostate tissue

Effective in relieving symptoms and restoring urine flow

Complication of TURP•Immediate complication bleeding

capsular perforation with fluid extravasation

TUR syndrome•Late complication urethral stricture

bladder neck contracture (BNC)

retrograde ejaculation

impotence (5-10%)

incontinence (0.1%)

Open Simple Prostatectomy

• “too large prostate” -- >100 gm • Combined with bladder diverticulum or

vesical stone surgery • Suprapubic or retropubic method

Minimally invasive therapy• During the last decade, numerous amounts of

minimally invasive therapy modalities have been developed to challenge the traditional surgery of TURP

• The aim of these therapies is to achieve results similar to TURP but with minimal anesthesia, complication, risk and hospital stay.

Minimally invasive therapy for BPH• transurethral balloon dilatation of the prostate (TUBDP) • transurethral incision of the prostate (TUI)• intraprostatic stent• transurethral microwave thermotherapy (TUMT)• transurethral needle ablation of the prostate (TUNA)• transurethral electrovaporization of the prostate (TUVP)• photoselective vaporization of the prostate (PVP), • Cryotherapy• Transurethral ethanol ablation of the prostate (TEAP),

Minimally invasive therapy for BPH• transurethral laser-induced prostatectomy (TULIP)• visual laser ablation of the prostate (VLAP)• contact laser prostatectomy (CLP)• interstitial laser coagulation of the prostate (ILC)• holmium:YAG laser resection of the prostate (HoLRP)• holmium:YAG laser enucleation of the prostate

(HoLEP)• high-intensity focused ultrasound (HIFU) coagulation• botulinum toxin-A injection of the prostate

Summary• Minimally invasive therapies for the treatment of BPH

has the advantages such as less blood loss, less occurrence of hyponatremia, quicker recovery, and reduced risk of urethral stricture.

• However, it also has the disadvantages such as long-lasting bladder irritation owing to higher temperature during therapy and possible longer catheterization period due to swelling of the prostate.

• It is still too early to make a definitive conclusion concerning the future role of these minimally invasive therapies for the treatment of BPH.
