introduction
• BPH is the most common benign tumor in men, and its
incidence is age-related.
• The prevalence of histologic BPH in autopsy studies rises
from approximately 20% in men aged 41-50, to 50% in men
aged 51-60, and to over 90% in men older than 80.
• Although clinical evidence of disease occurs less
commonly, symptoms of prostatic obstruction are also age-
related.
• At age 55, approximately 25% of men report obstructive
voiding symptoms. At age 75, 50% of men complain of a
decrease in the force and caliber of their urinary stream.

• Risk factors for the development of BPH are
poorly understood. Some studies have
suggested a genetic predisposition, and some
have noted racial differences. Approximately
50% of men under the age of 60 who undergo
surgery for BPH may have a heritable form of
the disease. This form is most likely an
autosomal dominant trait, and first-degree
male relatives of such patients carry an
increased relative risk of approximately 4-fold.

BPH
• ≥40yrs—increased growth
• Only 1 in 10 in 50yrs have symptoms
• Size vs symptoms
• Microscopic, macroscopic, clinical BPH
• Obstruction may result from
- static or dynamic components

BPH: Pathology
• testosterone →dihydrotestoterone → BPH
• Periurethral glands

• Median lobe ball valve
effect

BPH: symptoms
• Frequency, Nocturia
• Difficulty with micturition-hesitancy,poor
stream, terminal dribbling
• Urgency
• Retention- acute, chronic
• Incontinence
• Haematuria
• Recurrent UTI
• Fxs of renal failure-

BPH: Investigations
• diagnosis
urethrocystoscopy urethral cath-
r/o stricture
• extent urine m/c/s,
urea, electrolytes & creatinine,
(gfr), pcv
ultrasound- kub (+ pvr)
intravenous urogram? ipss,
peak urine flow rate( n=≥ 20ml/s),observe
• baseline- gxm blood, urinalysis,hiv, hbsag,ecg, chest x-ray,
psa

BPH: Differentials
• Urethral stricture
• Ca prostate
• Bladder neck obstruction
• Ca bladder
• Bladder calculus
• neurogenic bladder
• DM, Depression
3/21/2024 17

BPH; Mx- Watchful waiting
• Pts with minimal symptoms(IPSS<8, QOL-not
bothered)
• Follow up- IPSS, DRE, PSA,PFR,PVR,USS
• Contraindication- complication
3/21/2024 18
ogwuche E.I
Medical treatment
• Alpha blockers-phenoxybenzamin,prazosin,
doxazosin, tamsulosin, alfuzocin, terazosin
• 5-alpha reductase inhibitors – finasteride,
dutesteride (avodart)
Testosterone→Dihydrotestosterone by 5αR
• Combinations- alpha blockers +finasteride
• Plant extracts
3/21/2024 19

BPH-Mx Retention
• Acute -Catheter-urethral
-suprapubic puncture????
-duration of cath
• Chronic –Assess renal function-u/e/cr, uss, ivu
-good renal function-surgery next list
-poor fxn-continous drainage
-correct fluid/electrolytes,acidosis, anaemia
-antibiotic cover
- change catheter 2wkly
-prostatectomy when normal
3/21/2024 20
ogwuche E.I
PRE-OP PREP
• Catheter drainage if in retention. No need if
none
• Prophylactic antibiotics
• Correct fluid/elec, anaemia,uraemia,nutrition
• Screen to exclude pulmonary, cardiac dss, DM.
ie do CXR, Echo, RFTs, urinalysis, FBS
• Other Ix-GXM, urine mcs,HIV,HbsAg etc
