Male Urology Flashcards
What type of tissue comprises 30% of the prostate?
What comprises the other 70%?
30%: Glandular tissue
70%: Stroma
What is the smallest structural component of glandular prostate?
Acini
T/F: Proliferation of the acini results in BPH
True
Proliferation of the ________ (Acini/Basement Membrane) of the prostate leads to prostate cancer
Basement Membrane
What are the three zones of the prostate?
Central Zone
Transitional Zone
Peripheral Zone
Which zone of the prostate contains mucosal and submucosal glands?
Changes in this zone often lead to urethral pressure.
Periurethral Zone
Which zone of the prostate contains the majority of prostatic glandular tissue and is the origin site for most adenocarcinomas of the prostate?
Peripheral Zone
Which zone of the prostate is often described of as the “cone shaped” portion of the prostate?
Central Zone
T/F: The transitional zone of the prostate does NOT surround the urethra
False
It does surround the urethra
What percentage of men have BPH by the age of 60?
80?
60: 50%
80: 90%
What is the mechanism for BPH development?
Testosterone is broken down by 5alpha-reductase to form DHT
DHT then binds to nuclear receptors in the prostate leading to BPH
What receptors in the prostate (near the bladder neck) result in smooth muscle contraction leading to LUTS associated with BPH?
A1-Adrenergic Receptors
What are examples of obstructive LUTS?
Weal Stream
Hesitancy
Incomplete Emptying
Double voiding
What are examples of irritative LUTS?
Urgency
Frequency
Nocturia
What are FOUR key components to a BPH work-up?
DRE
UA
BMP
Baseline PSA
What ‘imaging’ study can be obtained to see if a patient is retaining urine?
PVR (Post-Void Residual)
What is the name of the ‘imaging study’ used to measure how strong a patient’s urine stream is?
Uroflow
What is the name of the procedure used to visual the inside of the bladder?
Cystoscopy
What may the appearance of the bladder be described as if it has been squeezing hard against the prostate?
Trabeculated
What medications used in BPH management “open up” the prostate through smooth muscle relaxation?
Alpha Blockers…..
Non-Selective: Terazosin (Hytrin), Doxazosin
Selective: Tamsulosin (Flomax), Silodosin (Rapaflo)
What medications used in BPH management “shrink” the prostatic glands?
%-alpha reductase inhibitors…..
Finasteride
Dutasteride
What is an antimuscarinic used in BPH management?
Oxybutynin
What are examples of surgical procedures used to manage BPH?
TURP
TUNA
TUMT
PVP
T/F: Recurrent UTIs attributable to BPH is NOT an indication for surgical management
False
It is an indication
