BPH - Bishay Flashcards
BPH histological diagnosis:
Proliferation of smooth muscle and epithelial cells within the prostatic TRANSITION ZONE.
LUTS - Storage Symptoms
frequency
nocturia
LUTS - Voiding Symptoms
hesitancy
intermittency
weak stream
dribbling
urgency with or without urge incontinence usually with frequency and nocturia
Overactive Bladder Syndrome
urodynamic observation of an involuntary detrusor contraction
Detrusor Overactivity
Define Benign Prostatic . . .
A) Hyperplasia
B) Enlargement
C) Obstruction
A) Hyperplasia - histological diagnosis
B) Enlargement - gland enlargement
C) Obstruction - obstruction is suspected based on flow rates/urodynamics
Bladder Outlet Obstruction
any obstructive process
Main drug classes used for treatment of LUTS
Alpha blockers (dynamic) 5-alpha reductase inhibitors (static)
Long Acting Alpha Blockers
Terazosin, Doxazosin, Alfuzosin
require dose titration
a1 Receptor Blockers
Tamsulosin (Flomax)
Sildosin (Rapiflo)
5 alpha reductase inhibitor action
blocks conversion of testosterone to DHT in prostate tissue
average 50% reduction in PSA
5 alpha reductase inhibitors are used in patients with a prostate > ______ grams or PSA > _____.
30 grams or PSA > 1.5
Patient has a small prostate gland or low PSA. What type of treatment do you use?
alpha-blocker
When to consult a urologist:
1) refractory to medical management
2) recurrent urinary retention
3) recurrent UTI
4) renal insufficiency
5) hematuria
6) bladder calculi
Cancer in the prostate occurs in what zone
Peripheral Zone
Patient presentation of BPH (LUTS)
Lower Urinary Tract Symptoms
1) Direct Bladder outlet obstruction (static component)
2) Increased smooth muscle tone and resistance (dynamic component)
- Frequency, nocturia (storage)
- Hesitancy, intermittency, weak stream, dribbling (Voiding)
Index patient according to AUA for BPH
Male aged 45 or older with LUTS
- No history suggesting non-BPH causes
- LUTS may or may not be due to enlarged prostate, BOO, or histological BPH
A questionnaire given to patients with LUTS. What is it called, what does it include and ow is it scored?
AUA Symptom Index (AUA-SI). 7 question and 1 quality of life question.
Mild: 0-7
Moderate: 8-19
Severe: 20-35
Recommended tests for LUTS
1) Medical hx
2) Assesment of LUTS
3) Severity and bother (AUA-SI)
4) DRE and PE
5) UA
6) Serum PSA
7) Frequency/volume chart
Polyuria is defined as:
> 3L in 24 hours
Modifiable factors of LUTS
Fluid intake
Alpha blockers:
Alfuzosin, doxazosin, Terazosin, Tamsulosin, Silodosin
5ARIs
Avodart and Finasteride
Patients with LUTS secondary to BPH whom an alpha blocker is offered, what syndrome do you need to worry about?
Intraoperative Floppy Iris Syndrome- If planned cataract surgery, hold alpha blocker until after
A patient has LUTS secondary to BPH and without an elevated PVR and mainly irritative symptoms, what should you consider prescribing?
Anticholinergics- M3 receptor (Ex: Oxybutynon)
Minimally invasive therapy for LUTS
Transurethral needle ablation-TUNA
Transurethral microwave thermotherapy- TUMT
Surgery Treatments for LUTS
1) Transurethral: Incision of prostate (TUIP), Vaporization of Prostate (TUVP), Resection of Prostate (TURP).
2) Open simple prostatectomy
3) Robotic/Laparoscopic simple prostatectomy
