Diseases of the Prostate Flashcards
Describe Overactive Bladder Syndrome (OAB)
- Not holding what it should
- Results in urinary urgency w/ or w/o incontinence, frequency, nocturia
Describe BPH
Asymptomatic microscopic detection of prostatic hyperplasia
Describe storage vs. voiding in LUTS
Storage: bladder issue
Voiding: prostate issue
1st line treatment of OAB
Behavioral and education (bladder training, biofeedback, pelvic floor muscle therapy)
2nd line treatment of OAB
Anticholinergic/antimuscarinics
3rd line treatment of OAB
Surgery
MC benign tumor in men?
BPH
What is the major hormone responsible for proliferation a/w BPH?
Dihydrotestosterone (DHT)
What is the single most important tool used in evaluation of patients for BPH?
American Urological Association Symptoms Index (higher score is more severe symptoms)
Treatment of BPH
- Based on severity
- Watchful waiting
- Meds (alpha blockers, 5a reductase inhibitors)
- Surgery
Pharm treatment of BPH
- 1st line: alpha blockers and 5a-reductase inhibitors
- 2nd line: PDE-5 inhibitors
How do alpha blockers work in BPH?
Relax smooth muscle in bladder neck and prostate gland (reducing obstruction and increasing urinary flow rates)
How do 5a-reductase inhibitors work in BPH?
- Blocks conversion of testosterone to DHT
- Decreases prostate size, increasing flow rate
How do PDE-5 inhibitors work in BPH?
Enhances smooth muscle relaxation in prostate, bladder, urethra
Etiology of acute bacterial prostatitis
Gram negative rods (E coli, Pseudomonas)
Pathophys of acute bacterial prostatitis
- Ascent of bacteria up the urethra
- Reflux of infected urine into prostatic ducts
Presentation of nonbacterial prostatitis
Identical to chronic bacterial prostatitis EXCEPT NO hx of urinary tract infections
Etiology of nonbacterial prostatitis
Unknown - diagnosis of exclusion
Mechanisms of ED
- Failure to initiate
- Failure to fill
- Failure to store adequate blood volume w/in lacunar network
Weak flow of urine suggests?
Prostate problem
Voiding small amounts of urine or more frequently suggests?
Bladder problem
Pharm agents used to treat OAB
- Oxybutinin
- Fesoterodine
- Tolterodine
- Solifenacin
When is watchful waiting best for BPH?
Patients with mild disease (AUA Symptoms Index score 0-7)
What is the place of combo therapy in BPH?
alpha blocker + 5a reductase inhibitors have been shown to reduce risk of progression
What is the conventional surgical therapy of BPH?
- Transurethral resection of prostate (TURP)
- Transurethral incision of prostate (TUIP)
- Open simple prostatectomy
What are minimally invasive surgeries to treat BPH?
- Laser therapy (ablation)
- Transurethral needle ablation (TUNA)
- Electrovaporization
- Hyperthermia
What does CBC show for acute bacterial prostatitis?
Leukocytosis with a left shift
What does urinalysis show for acute bacterial prostatitis?
Pyuria, bacteriuria and +/- hematuria
How is uncomplicated acute bacterial prostatitis defined?
- Under 35 and risk of STD
- Over 35 and low risk of STD
Treatment of acute bacterial prostatitis under 35 yo at risk for STD?
- Treat as an STD
- Cover for both chlamydia, gonorrhea
- Ceftriaxone plus Doxy OR Azithro
Treatment of acute bacterial prostatitis over 35 yo low risk for STD?
Fluoroquinolone OR Bactrim (some recommend up to 4 wks tx)
Treatment of hospitalized acute bacterial prostatitis?
- Parenteral abx (ampicillin and aminoglycosides) until culture results are back
- Once afebrile for 48 hours, oral abx (quinolones) 4-6 wks
What is diagnostic for chronic bacterial prostatitis?
Positive culture of prostate secretions or the post prostatic massage urine specimen
Treatment of chronic bacterial prostatitis
Abx 6-12 weeks
- Bactrim
- Cipro
- Ofloxacin
Prognosis of chronic bacterial prostatitis
- Difficult to cure
- Typically results in recurrent UTIs
Treatment of nonbacterial prostatitis
NSAIDs or Sitz baths for symptomatic relief
Incidence of ED is higher in which men?
Those with certain illnesses (DM, obesity, BPH, HTN, etc)
MC cause of ED
Vasculogenic - decreased blood flow to and from penis (e.g. athero)
Treatment of ED
- Lifestyle: wt loss, exercise, smoking cessation, decrease ETOH
- Oral PDE-5 inhibitors
- Injection therapies
- Testosterone therapy
- Penile devices
- Psych/sex therapy
- Surgery (prosthesis)
Describe a vacuum constriction device
Draws venous blood into penis and uses a constriction ring to restrict venous blood return and maintain erection
