Benign Prostate Hyperplasia
Benign Prostate Hyperplasia
Enlargement of prostate gland
resulting from increase in number of
epithelial cells and stromal tissue
Most common urologic problem in
males
2
Benign Prostate Hyperplasia
Occurs in 50% of men over 50 and
90% of men over 80
Approximately 25% will require
treatment by age 80.
Does not predispose to
development of prostate cancer
3
Etiology and Pathophysiology
Possible causes
• Excessive accumulation of
dihydroxytestosterone
• Stimulation by estrogen
• Local growth hormone action
Typically develops in inner part of
prostate while prostate cancer is
most likely to develop in outer part.
4
Etiology and Pathophysiology
Possible risk factors
• Family history
• Obesity
• Increased waist circumference
• Physical activity level
• Alcohol consumption, smoking
• Diabetes
5
Etiology and Pathophysiology
Enlargement gradually compresses
urethra.
• Partial or complete obstruction
Compression leads to clinical
symptoms.

7
Clinical Manifestations
Symptoms are usually gradual in
onset.
Early symptoms are usually minimal
because bladder can compensate.
Worsen as obstruction increases
8
Clinical Manifestations
Symptoms categorized into two
groups
• Obstructive symptoms
• Irritative symptoms
9
Clinical Manifestations
Obstructive symptoms
• Symptoms due to urinary retention
• Decrease in caliber of force of urinary
stream
• Difficulty in initiating urination
• Intermittency
• Dribbling at end of voiding
10
Clinical Manifestations
Irritative symptoms
• Symptoms associated with
inflammation or infection
• Urinary frequency and urgency
• Dysuria
• Bladder pain
• Nocturia
• Incontinence
11
Complications
Related to urinary obstruction
• Acute urinary retention: complication
with sudden, painful inability to
urinate
• Treatment involves catheter insertion
and possible surgery.
12
Complications
UTI and sepsis
• Incomplete bladder emptying with
residual urine provides medium for
bacterial growth.
13
Complications
Calculi may develop in bladder
because of alkalinization of residual
urine.
Renal failure: caused by
hydronephrosis
Pyelonephritis
Bladder damage
14
Diagnostic Studies
History and PE
DRE (Digital Rectal Exam)
Urinalysis with culture
PSA level
Serum creatinine
15
Diagnostic Studies
TRUS scan
Uroflometry
Cystoscopy
16
Collaborative Care
Goals
• Restore bladder drainage.
• Relieve symptoms.
• Prevent/treat complications.
Watchful waiting
Dietary changes
Timed voiding schedule
17
Collaborative Care
Drug therapy offers symptomatic
relief of BPH
• 5α-Reductase inhibitors
• Example: finasteride (Proscar)
• ↓ size of prostate gland
• Takes 3 to 6 months for improvement
• Side effects: decreased libido, decreased
volume of ejaculation, ED
18
Collaborative Care
• α-Adrenergic receptor blockers
• Examples: tamsulosin (Flomax),
Promotes smooth muscle relaxation in
prostate; facilitates urinary flow
• Improvement in 2 to 3 weeks
• Side effects: orthostatic hypotension and
dizziness, retrograde ejaculation, nasal
congestion
19
Collaborative Care
Transurethral microwave therapy
https://youtu.be/zuN-yXqH-TI?si=50hmkGjezj_EmzIv&t=5
• Outpatient procedure: delivers
microwaves directly to prostate
through a transurethral probe
• Heat causes death of tissue and relief
of obstruction.
20
Collaborative Care
Transurethral microwave therapy
(cont’d)
Postop urinary retention is common
• Patient sent home with catheter 2 to 7
days
• Antibiotics, pain medication, and
bladder antispasmodic medications
given
21
Collaborative Care
Transurethral microwave therapy
(cont’d)
• Not appropriate therapy when rectal
problems exist
• Side effects: bladder spasm,
hematuria, dysuria, and retention
22
Collaborative Care
Transurethral needle ablation
(TUNA)
• ↑ temperature of prostate tissue for
localized necrosis
• Low-wave frequency used
• Only tissue in contact with needle
affected
23
Collaborative Care
Transurethral needle ablation
(cont’d)
• Majority of patients show
improvement in symptoms.
• Outpatient uses local anesthesia and
sedation.
• Lasts 30 minutes with little pain and
quick recovery
24
Collaborative Care
Transurethral needle ablation
(cont’d)
• Complications include urinary
retention, UTI, and irritative voiding
symptoms.
• Some patients require a catheter.
• Hematuria up to a week
25
Collaborative Care
Laser prostatectomy
• Delivers a laser beam transurethrally
to cut or destroy parts of the prostate
• Common procedure: visual laser
ablation of the prostate (VLAP)
• Takes several weeks to reach optimal
results
• Urinary catheter inserted
26
Collaborative Care
Laser prostatectomy (cont’d)
• Contact laser techniques
• Minimal bleeding during and after
procedure
• Fast recovery time
• Patients may take anticoagulants.
• Photovaporization of the prostate
27
Collaborative Care
Invasive therapy indicated when
• Decrease in urine flow sufficient to
cause discomfort
• Persistent residual urine
• Acute urinary retention
• Intermittent catheterization can
reduce symptoms and bypass
obstruction
28
Collaborative Care
Transurethral resection (TURP)
• Removal of obstructing prostate
tissue using resectoscope inserted
through urethra
• Outcome for 80% to 90% is excellent.
• Relatively low risk
• Performed under spinal or general
anesthesia and requires hospital stay

Collaborative Care
Transurethral resection (cont’d)
• Bladder irrigated for first 24 hours to
prevent mucous and blood clots
• https://youtu.be/9wGZ7YjuaFA?si=mOZJtrtqTe0Sn17G&t=29
• Complications include bleeding, clot
retention, dilutional hyponatremia,
retrograde ejaculation.

Use aseptic technique when using
urinary catheter.
Administer antibiotics
preoperatively.
32
Nursing Implementation
Preoperative care
Provide patient opportunity to
express concerns over alterations in
sexual function.
Inform patient of possible
complications of procedures.
33
Planning
Goals for postoperative care
• No complications
• Restoration of urinary control
• Complete bladder emptying
• Satisfactory sexual expression
34

Postop bladder irrigation to remove
blood clots and ensure drainage or
urine

infection.
Dietary intervention-high fiber
Stool softeners to prevent straining
36
Nursing Implementation
Focus: early detection and
treatment
Yearly physical exam and DRE for
men over 50
Educate patients that alcohol,
caffeine, and cold and cough meds
can increase symptoms.
37

Signs and symptoms of UTI, wound
infection
38
Nursing Implementation
Preventing constipation
Avoiding heavy lifting

after surgery as directed
39
Nursing Implementation
Sexual counseling if erectile
dysfunction becomes a problem
Avoiding bladder irritants
Yearly digital rectal examination
(DRE)

Student Response Question
A patient with benign prostatic hyperplasia is scheduled
for a transurethral resection of the prostate (TURP). The
nurse assesses the patient’s knowledge of the procedure
and its effects on reproductive function, and determines a
need for further teaching when the patient says,
1. “It is possible that I’ll be sterile following this
procedure.”
2. “It is likely that I will become impotent from this
procedure.”
3. “I understand that some retrograde ejaculation may
occur.”
4. “I will have a catheter for a couple of days to keep my
urinary system open.”
