Q

what is acute bacterial prostatitis? what bug causes it most of the time? what other bugs can cause it? what can cause it?

A

infxn of prostate with pathogens from colorectal flora (E. coli MC, proteus, klebsiella, enterobacter, pseudomonas)
can be caused by increased intraprostatic ductal reflux resulting in urine moving bacteria into the prostate via ejaculatory and prostatic ducts into peripheral zone

A

TMP-SMX 80-400 mg BID or oral fluoroquinolones for 4+ weeks (500 mg cipro BID)
sxs mb relieved during tx but after abx done can lead to recurrence
abx if given 6-12 tend to produce a cure with few relapses

dysuria, urgency
low back/perineal pn referred to tip of penis
sense of rectal fullness after unsuccessful defecation
sexual dysfxn, post-ejaculation pn, decreased libido
possible hemospermia
fatigue, stress
PE: prostate palpation - mildly tender, boggy, rarely enlarged, assess tenderness of pelvic floor and sidewalls, also examine for hernia, testicular masses and hemorrhoids

24
Q

labs of chronic nonbacterial prostatitis?

A

UA, urince C/S, EPS cell count and culture, CBC and blood cultures if sepsis
mb hematuria, PSA <4
if inflammatory WBCs present in semen, EPS, VB3
if non-inflammatory WBCs not present in samples
a urethral swab is indicated to r/o chlamydia, gonorrhea if four glass urinalysis is (=)
consider: TRUS, abd CT, flowmetry, IVP

25
Q

chronic nonbacterial prostatitis is similar to what other somatic syndromes?

A

fibromyalgia, IBS, CFS, IC, CPPS, “biopsychosocial conditions”

26
Q

theories of etiology of CP/CPPS?

A

psychological stress increasing local production of IL-10, IL-6
infection from otherwise normal bac in prostatic fluid
AI vs prostate
low T leading to prostate inflam
increased NGF, increasing sensitivity of pelvic nerves
genetic: differences in DNA sequences that regulate cytokines

27
Q

ddx of chronic nonbacterial prostatitis?

A

include workup for CaP, obstructive uropathy, bladder cancer, urethritis, neurogenic bladder

28
Q

treatment considerations for chronic nonbacterial prostatitis?

A 
alpha-blocker therapy for newly dx, alpha-blocker-naive pts
abx for newly dx, abx-naive pts
finasteride, elmiron, opioids, amitriptyline, gabapentin
*invasive surgical therapies not recommended
heat therapy
cernilton 500 mg TID
quercetin
potassium citrate to alkalinize urine
biofeedback
acupuncture
E-stim
myofascial release therapy
immunomodulating agents
muscle relaxants
pudendal nerve modulation
prostatic massage 
identify and remove food allergens
anti-inflam diet
constitutional hydrotherapy, sitz baths
support groups
29
Q

asx inflammatory prostatitis presentation? tx for what group of pts and what is the tx?

A

no subjective sxs but WBCs found in prostate secretions or in prostate bx
abx tx for selected pts w/elevated PSA and infertility

30
Q

sxs of prostatic obstruction are related to what?

A

age!
at 55 yo, 25% report obstructive voiding sxs
at 75 yo, 50% complain of decrease in force and caliber of urinary stream

31
Q

RFs for benign prostatic hyperplasia?

A

genetic predisposition
age
race
meds (antihistamines, diuretics, opiates, TCAs, anticholinergics)

32
Q

etiology of BPH?

A

hyperplastic nodules and associated BPH sx can result from excessive proliferation of cell types and impaired preprogrammed cell death

33
Q

effects of aging dec of T, increase in E, increase in SHBG on prostate tissue?

A

dec T, inc E, inc SHBG lead to inc amount and activity of intraprostatic DHT which inhibits prostatic stem cell death and promotes transition zone growth

34
Q

pathology of BPH?

A

cells in the transition zone undergo hyperplasia from stimulation by DHT and E, not malignant, no METS

35
Q

BPH sxs from what two things?

A

obstruction: due to intrusion into the urethral lumen or bladder neck leading to incr bladder outlet resistance
resistance: leads to irritative voiding complaints; detrusor muscle hypertonicity and hyperplasia, collagen deposition, possible diverticular formation and weakened bladder wall

36
Q

ssxs and PE of BPH?

A

early mb asx
obstructive sxs include hesitance, decreased force, caliber of stream, sensation of incomplete emptying, double voiding, straining to urinate, post-void dribbling
irritative sxs include urgency, frequency and nocturia
PE: smooth, firm, rubbery, NT enlargement, no nodules, median bar can be mistaken for a nodule

37
Q

what finding on DRE should increase your suspicion for CaP?

A

induration and enlargement

38
Q

what labs to order with suspicion of BPH?

A

UA to exclude infxn or hematuria, C and S necessary
BUN and Cr to assess renal fxn
PSA levels (have to do before DRE or 2 wks after DRE as f/u to r/o CaP)

39
Q

what imaging to workup BPH?

A

TRUS
IVP if concomitant urinary tract dz
optional: cystometrogram pressure flow studies, post-void residual urine, uroflowmetry

40
Q

DDX of BPH?

A

CaP, urinary bladder dysfxn, UTI, IC, chronic prostatitis, enlarged non-hyperplastic prostate

41
Q

complications of BPH?

A

UTI, bladder stones, obstructive nephropathy, renal failure

42
Q

treatment for BPH?

A

watchful waiting
alpha-blockers, alpha-1 adrenergic blockers
selective alpha blockers, 5 alpha-reductase inhibitors,
prostatic stent, YAG laser, TUNA, BDP, TURP, TUMT, PVP
discourage straining to urinate, avoid fluids after 7 pm, avoid EtOH, caffeine, salt, diuretics, spicy foods, meats with hormones, consume foods high in EFAs, consume high fiber foods, serenoa repens, urtica, curcubita pepo, soy for phytoestrogenic effect, beta-sitosterols in rice bran, alanine, glutamine, glycine, physiotherapy, protomorphogens, prostatic massage, sitz baths

43
Q

SEs of alpha blocker therapy for BPH?

A

caution use in those with sulfa allergy
can cause retrograde ejaculation, hypotension
caution use in those with cataracts surgery

44
Q

benefits of 5 alpha-reductase inhibitors in treating BPH? SEs?

A

helpful for men w/prostate greater than 40 cm^2
can decrease PSA levels
after 6 mos of use decr risk of infxn, decr need for surgical intervention
SEs include decr libido, ED, possible incr risk for CaP

45
Q

prognosis and tx for men with prostate less than 60 cm? complications of BPH?

A

watchful waiting combined with naturopathic therapies is reasonable though not proven approach
complications include acute urinary retention, recurrent infections, intestinal herniation, hemorrhoids
