BPH, Prostate cancer Flashcards
Pathophysiology of BPH
Inner (transitional layer of prostate affected)
5α-reducatase converts testosterone to DHT
Increased DHT causes hyperplasia
Presentation of BPH
Storage symptoms
Voiding symptoms
Bladder stones
UTI
Storage symptoms
Nocturia
Frequency
Urgency
Overflow incontinence
Voiding symptoms
Hesitancy
Poor stream
Terminal dribbling
Incomplete emptying
Pis en deux
Pis en deux
residual urine results in a desire to pass urine soon after voiding
PR findings for BPH
Smoothly enlarged prostate
Definable median sulcus
Ix for BPH
U+Es, PSA
Urine dip and MCS
Transrectal US +/- biopsy
Urodynamics
Conservative Mx of BPH
Reduce caffeine and EtOH
Double voiding
Bladder training
Medical Mx of BPH
1st) Tamsulosin - α-blockers, relax smooth muscle
2nd) Finasteride - 5α-reducatase inhibitor
Side effects of tamsulosin
Drowsiness
Hypotension
Depression
Weight gain
Side effects of finasteride
Erectile Dysfunction
Excreted in semen (use condoms)
Surgical Mx of BPH
TURP, TUIP
Laser prostatectomy
Open retropubic prostatectomy
TUIP
Transurethral Incision of Prostate
Advantages of TUIP over other methods
less risk to sexual funtion
Immediate TURP complications
Haemorrhage
TURP syndrome
TURP syndrome
large fluid absorption leading to hyponatraemia
Early TURP complications
Haemorrhage
Infection
Clot retention
Late TURP complications
Retrograde ejaculation
ED
Incontinence
Urethral stricture
Recurrence
Race with higher incidence of prostate cancer

Mets: bone pain
Storage/Voiding Sx
PR findings of prostate cancer
Hard irregular/craggy prostate
Loss of midline sulcus
Common metastasis sites of prostate cancer
