what is the MC route of acute bacterial prostatitis infections
ascent up the urethra (can occur due to cystitis or urethritis)
what are risk factors for acute bacterial prostatitis
Factors predisposing GU infections such as:
- catheters
- prostate biopsy
- urethral stricture
anecdotal risks (no strong supporting evidence)
* trama
* dehydration
* sexual abstinence
what are the MC causative organisms in acute bacterial prostatitis
gram negative rods such as:
- E. coli (58-88%)
- psuedomonas (3-7%)
- proteus (3-6%)
other pathogens such as G+ bacteria and STDS can also cause it
how common is acute bacterial prostatitis
Relatively rare (~4% of prostatitis)
what are symptoms of acute bacterial prostatitis
- fever/chills (common)
- malaise (common)
- pain (peripheral, sacral, suprapubic)
- irritative voiding s/s
- occasionally obstructive voiding s/s
what are physical exam findings of acute bacterial prostatitis
a digital rectal exam showing hot and very tender prostate
what is contraindicated in acute bacterial prostatitis
prostatic massage due to risk of septicemia
what lab findings are seen in acute bacterial prostatitis
- CBC - leukocytosis and left shift
- urinalysis - pyuria, bacteriuria, hematuria
- urine culture - + for causative agent
when is imaging obtained in acute bacterial prostatitis? what imaging is used?
if there is no response to abx in 24-48 hours get a pelvic CT or transrectal US to assess for prostatic abscess
once a patient is diagnosed with acute bacterial prostatitis what should they recieve? why?
all patients should recieve a gram stain +C/S so you can adjust abx according to results!
what is type of patient is appropriate for outpatient treatment?
- no comorbidites
- no s/s of sepsis
- able to take PO abx
what indicated the need for hospitalization in an acute bacterial prostatitis patient
- severe s/s
- compicated case (surgical drainage)
- suspected bacteremia
what is the IV abx treatment for acute bacterial prostatitis that is NOT nosocomial
- Glouroquinolone +/- aminoglycoside
- amp/gent
what is the IV abx treatment for nosocomial acute bacterial prostatitis
- IV carbapenem
- IV broad spectrum PCN +/- aminoglycoside
- IV broad spectrum cephalosporin +/- aminoglycoside
what is the oral abx treatment for acute bacterial prostatitis
- bactrim BID
- cipro BID or levo QD
- if <35 or high risk sexual behavior consider G+C coverage (idk what this means)
how long should abx therapy last for acute bacterial prostatitis? what should be monitored during this time?
4 weeks
monitor the following to ensure resolution:
- UA/UC
- rectal exam
- inflammatory markers
what are the MC causative agents in chronic bacterial prostatitis
gram negative rods!
- E. coli (MC 75-80%)
- klebsiella
- enterococcus
- proteus
- pseudomonas
what is the MC routes of infection for chronic bcterial prostatitis
- ascent up urethra (MC)
- complicaiton of ABP
- many dont have any hx of acute prostatitis
what are the symptoms seen in chronic bacterial prostatitis
- some are asymptomatic
- irritative voiding s/s (MC)
- may see obstructive s/s
- pain that is dull, poorly located, in suprapubic, perineal or low back regions
what are the PE findings for chronic bacterial prostatitis
DRE would often be normal but may show boggy/spongy, tender, enlarged and/or indurated prostate
what labs are seen in chronic bacterial prostatitis
- UA - normal unless cystitis present
- prostatic secretions - increased WBC(>10) with + culture and lipid laden macrophages
- urine culture - negative (often + for causative organism AFTER prostatic massage
when is imaging needed in chronic bacterial prostatitis
“usually not needed” but if you do get imaging you may see prostatic calculi
what is the treatment for chronic bacterial prostatitis
- fluoroquinolones or bactrim!
- anti inflammatory agents
- sitz baths
how long should chronic bacterial prostatitis patients be on abx
at least 6 weeks and up to 12 weeks.
what must you educate your patient on when having them on abx for 6-12 weeks
educate them of the SE of prolonged use such as C diff, CNS toxicity, tendimopathy
what is nonbacterial prostatitis/chronic pelvic pain syndrome
Characterized by pelvic pain/discomfort in men, accompanied by urologic symptoms and/or sexual dysfunction
what is the difference between nonbacterial prostatitis and chronic pekvic pain syndrome
- inflammatory is nonbacterial aka chronic protatitis
- non-inflammatory is CPPS aka prostatodynia
how common is prostatitis and at what age does incidence of prostatitis peak in?
2-10% of adult men have protatitis and MC form is nonbacterial or CPPS
5th decade of life
what is the etiology of CPPS or non bacterial prostatits
unknonw
what are the sympotms of nonbacterial prostatitis or CPPS
- irritative/obstructive voiding
- pain in peripheral, lower abdomen, or low back (often dull and poorly localised)
- may present with another type of chornic pain syndrome such as fibromyalgia
what are the PE findings for nonbacterial prostatitis or CPPS
- DRE showing tenderness in 50% of patients
what are the lab findings in nonbacterial prostatitis or CPPS
- UA - unremarkable
- prostatic secretions - incerased WBC if inflammatory, normal if noninflammatory. negative culture!
- urine culture - negative!
when is imaging obtained in nobacterial prostatitis or CPPS
mainly to rule out other pathologies
what is treatment for nonbacterial prostatitis or CPPS
- newly diagnosed - abx therapy such as flouroquiniolones or erythromycin for 6 weeks.
discontinue abx in 2 weeks if no improvement - urainary symptoms - alpha blockers
- 5-a-reductase inhibitors
- NSAIDS
- sitz baths
- CAM
- PT
what are the alpha blockers used for urinary symptoms
- tamsulosin/sildosin/alfuzosin (less SE)
- prazosin, terazosin and doxazosin can also be used!
what is the mechanism for alpha blockers treating urinary symptoms
Alpha-blockers - block 𝛼-1 receptors in the bladder neck and smooth muscle in the prostate, causing relaxation and increased urethral size
what are the 5-a-reductase inhibitors and when are they NOT reccomended
- finasteride, dutasteride
- not reccomended in young men d/t decreased semen volume
what are sequelae that may need to be addressed individually during the treatment of nonbacterial prostatitis or CPPS
- Neuropathic pain
- Psychosocial disorders
- Pelvic floor muscle dysfunction
- Sexual dysfunction
a nice lil chart for ya
what is benign prostatic hyperplasia
MC benign tumor in men causing increase in both glandular and stromal components of the prostate
what is hte epidemiology for BPH
- 8% of men 31-40
- 50% of men 51-60
- Over 80% of men 80+
- black men are more likely to have severe s/s and need surgery
- asian men are less likely than black or white men to have BPH
how common are obstructive voiding s/s in BPH
- 25% of 55-yr-old men
- 50% of 75-yr-old men
what are risk factors for BPH
- higher free PSA levels
- prostatitis
- heart disease
- BB use
- lack of exercise
- obesity
what decreases risk of BPH
- NSAIDS
- excessive ETOH use
- smoking
- exercse
this just doesnt sound right but she said it in class that these things all reduce likelihood of BPH ¯_(ツ)_/¯
what is the etiology of BPH
multifactoral etiology including:
- aging prostate are more sensitive to androgens and growth factors
- aging stops normal cell death
- testosterone, dihydrotestosterone and estrogen may be involved
what are the 2 mechanisms of obstruction in BPH
- mechanical obstruction due to narrowing of urethral lumen or bladder neck
- dynamic obstruction d/t alpha receptor stimulation (causes increased constriction to prostatic urethra)
note: Prostate size does not always correlate with symptoms!
what are the symptoms of BPH
- obstructive voiding s/s such as:
- Urine hesitancy
- Decreased force and caliber of stream
- Sensation of incomplete bladder emptying
- Double voiding (urinating within 2 hours)
- Straining to urinate
- Postvoid dribbling
- also irritative voiding sympotms such as urgency, frequency and nocturia
symptoms are very slow onset and gradually progress
what causes the irritative voiding symptoms in BPH
- Due to secondary response of bladder to increased outlet resistance
- Detrusor muscle hypertrophy and hyperplasia, collagen deposition
what assesses severity of BPH symptoms
AUA symptom score!

what does the PE show in BPH
DRE showing smooth, firm, symmetric, elastic enlargement of prostate
