PROSTATITIS Presented by Dr.Bandar Al Hubaishy KAUH
Epidemiology • Prostatitis is the most common urologic diagnosis in males<50 years and the • The third most common diagnosis in men>50 years • Of 600 men diagnosed with prostatitis, 5% had bacterial prostatitis, 64% had nonbacterial prostatitis, and 31% had pelvic-perineal pain syndrome
Category I: Acute Bacterial Prostatitis • It is caused by bacterial infection of the prostate gland. • It is much less common than chronic prostatitis but is easier to identify
Pathophysiology • Microbiologic causes • Risk Factor
Microbiogic Causes • Gram-negative members of the Enterobacteriaceae family. • They include Escherichia coli, Proteus mirabilis, Klebsiellaspecies, Enterobacter species, Pseudomonas aeruginosa, and Serratia species. • E coli is responsible for 65% – 80% of the cases • Pseudomonas aeruginosa, and Serratia species are responsible for 10% - 15%
Microbiogic Causes • Obligate anaerobic bacteria and gram-positive bacteria other than enterococci rarely cause acute bacterial prostatitis. • Enterococci account for 5-10% of documented prostate infections. • Staphylococcus aureus infection due to prolonged catheterization may occur in the hospital.
Microbiogic Causes • Other occasional causative organisms include Neisseria gonorrhea,Mycobacterium tuberculosis,Salmonella species, Clostridium species, and parasitic or mycotic organisms. N gonorrhea should be suspected in sexually active men younger than 35 years.
Risk Factors • Intraprostatic urinary reflux
Risk Factor • Ascending urethral infection • sexual intercourse • instrumentation • prolonged catheterization • Direct invasion or lymphogenous spread from the rectum • Direct hematogenous infection • Unprotected anal intercourse • Acute epididymitis • Altered prostatic secretions • Phymosis and redundant skin
Clinical presentation • Systemic symptoms: fever,chilis, malaise, arthalgia, vomiting, septicemia and hypotension • Irritative symptoms: dysuria, frequency, urgency • Obstructive symptoms: hesitancy, poor interrupted stream, strangury, and even acute urinary retention are common. • Perineal and suprapubic pain
Physical Examination • Vitals • Abdomen Ex • DRE: enlarged, tender, firm prostate gland Note:avoid vigorous prostatic massage in a patient with suspected acute bacterial prostatitis to prevent bacteremia and sepsis.
Work up • Complete blood count: leukocytosis • Urine analysis: It shows large number of WBC • Urodynamics: Helps to avoid misdiagnosis of prostatitis
Work up • Serumprostate-specific antigen: PSA has little to no clinical value. If the PSA level is obtained and is found to be elevated the study should be repeated 30-60 days after adequate treatment.
Work up • Imaging Studies : CT scanning of the pelvis ortransrectal ultrasonography • Indications: 1-Laboratory analysis findings are equivocal 2- No improvement is observed following medical therapy. 3- Ruling out complications of prostatitis (eg, prostatic abscess)
Work up • Prostate biopsy: It is contraindicated in cases of suspected acute bacterial prostatitis • Complications: 1-Seeding the bacterial infection in adjacent organs. 2-Sepsis.
Managemet • Medical treatment • Surgical Treatment
Medical treatment • Supportive therapy: Antipyretics, analgesics, stool softeners, bed rest, and increased fluid intake provide • Urinary retention: A Foley catheter can be inserted gently for drainage if severe obstruction is suspected. A punch suprapubic tube can be used if a catheter cannot be passed easily or is not tolerated by the patient. The catheter can be removed 24-36 hours later.
Medical treatment • Antibiotic therapy The initial therapy must be directed to Gram-ve microorganism. Useful agents include fluoroquinolones, trimethoprim-sulfamethoxazole, and ampicillin with gentamicin.
Medical treatment • Intravenous therapy, use trimethoprim-sulfamethoxazole (Bactrim), 8-10 mg/kg/d (based on the trimethoprim component) in 2-4 intravenous doses bid, tid, or qid until the culture and sensitivity results are known. An alternate regimen is gentamicin with ampicillin 3-5 mg/kg/d IV (gentamicin dose divided tid and 2 g ampicillin divided qid).
Medical treatment • If the initial clinical response to therapy is satisfactory, treatment is continued orally for 30 days to prevent sequelae such as chronic bacterialprostatitis and prostatic abscess formation.
Medical treatment • For oral therapy, Use trimethoprim-sulfamethoxazole (Bactrim), 160 mg of trimethoprim and 800 mg of sulfamethoxazole, PO bid for 30 days. Use levofloxacin (Levaquin) 500 mg PO bid; ciprofloxacin, 500 mg PO bid; norfloxacin, 400 mg PO bid; ofloxacin, 400 mg PO bid; or enoxacin, 400 mg PO bid for 30 days when clinical response is favorable.
Medical treatment • Alpha-blocker therapy : • It improve outflow obstruction and diminish intraprostatic urinary reflux • Terazosin 5 mg/d PO for 4-52 wk, Tamsulosin (Flomax), alfuzosin (UroXatral) and doxazosin (Cardura) are acceptable alternatives
Complication of acute prostatitis • Prostatic Abscess • Progression to chronic prostatitis, septicemia, • Pyelonephritis, and • Epididymitis.
Surgical Treatment Indication: Prostatic Abscess
Prostatic abscess • Prostatic abscess is an uncommon but well-described. • Coliform bacteria, especially E coli, cause more than 70% of prostatic abscesses • Risk Factors: Immunocompromised DM Urethral instrumentation. Prolonged indwelling urethral catheters. Patients on maintenance dialysis.
Management • Clindamycin intravenously at 600-900 mg q8h or orally at 150-450 mg q8h is a good choice. However, medical management is often unsuccessful. • Transrectal or perineal aspiration of the abscess if symptoms do not improve after 1 week of medical therapy. • Transurethral resection of the prostate and drainage of the abscess. Recurrent abscesses are rare. The abscess should be allowed to drain and should be monitored closely if a spontaneous rupture occurs into the urethra.
Category II: Chronic Bacterial Prostatitis • 35-55% of men have prostatitis symptoms. • Recent studies show that prostatitis has the same effect on a patient's mental health as does diabetes mellitus and congestive heart failure. • Recent studies using the US National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) found that the prevalence of prostatitis symptoms was 10% in a population of men aged 20-74 years.
Clinical Presentation • Genitourinary pain it occurs in the perineal area, penile tip, testicles, rectum, lower abdomen, and back. • Patients can also have irritative or obstructive urologic symptoms • Other symptoms include a clear-to-milky urethral discharge, ejaculatory pain, hematospermia, and sexual dysfunction.
Physical Examination • Physical examination findings are often nonspecific • The classic presentation : an enlarged, soft, or, boggy gland that is moderately-to-severely tender upon palpation. • In some cases, an examiner is able to palpate prostatic stones..
Pathophysiology • Predisposing factors: Acute bacterial prostatitis Prostatic calculi Uretheral stricture and refluxing urine
Pathology • Escherichia coli • Klebsiella pneumoniae • Pseudomonas aeruginosa • Proteusspecies • Staphylococcusspecies • Enterococcusspecies • Trichomonasspecies • Candidaspecies • C trachomatis • U urealyticum • M hominis
Work up • The 2 glass test Positive urine culture findings after a prostatic massage Criteria for the diagnosis: 1- WBCs in an EPS is more than 10 WBCs/hpf (40X objective) or an observation of clumping WBCs with the presence of oval fat bodies 2- a positive EPS culture finding
Work up • Imaging Studies: Transrectal Ultrasound or CT pelvis It is useful for detecting prostaric calculi • Prostate biopsy:
Work up • If the patient has frequent recurrences of chronic prostatitis, other tests may help exclude an anatomic obstruction due to: 1- prostatic hyperplasia, 2- urinary stricture disease, 3- bladder neck dysfunction. • Retrograde urethrography, uroflowmetry, and postvoid residual testing and cystoscopy.
Management • Antimicrobial therapy: The Ideal antibiotics must have: 1- Higher dissociation constant to allow diffusion of their un-ionized components into the prostate. 2-The antibiotic must be basic, it can readily concentrate much in the gland
Management • The best antibiotic choices include 1-trimethoprim-sulfamethoxazole (TMP-SMZ) at 80-400 mg given twice a day 2-fluoroquinolone antibiotics (eg, ciprofloxacin at 500 mg or ofloxacin at 400 mg) twice a day 3-gatifloxacin/moxifloxacin at 400 mg daily. NOTE :TMP-SMZ yields a 33-50% cure rate with a 4- to 6-week course of treatment. Fluoroquinolones yield a similar cure rate with a 4-week course.
Management • If oral antibiotic therapy fails, use other antibiotics. • These may include carbenicillin or doxycycline or injections of gentamicin, either parenterally or directly into the prostate.
Management • Persistent infections, especially those who have symptom improvement while on antibiotics but quickly have a recurrence after finishing a course of antibiotics, may benefit from suppressive therapy with low daily doses of antibiotics. • Good choices are tetracycline, nitrofurantoin,nalidixicacid, cephalexin, or trimethoprim.
Management • Nonsteroidal anti-inflammatory drugs and alpha-blockers . • Surgical Treatment TURP or TUVP are not indicated except in certain condition when a patient has recurrent episodes of chronic prostatitis and improves with antibiotics
Category III: Chronic Pelvic Pain Syndrome • There is no difference between Category IIIA and Category IIIB • It is the most common category of prostatitis • It affects the quality of life
Pathophysiology • The etiology (or etiologies) of CPPS remains unknown • Special signaling molecules called cytokines, which are produced by WBCs (and by other cells), may play a role. • Genetic factors • Autoimmunity,
Pathophysiology • Testosterone • Abnormal functioning of the nervous system • Psychological stress and depression
Clinical presentation • The predominant is pain, which was most commonly localized to the perineum, suprapubic area, and penis but can also occur in the testes, groin, or low back. • Pain during or after ejaculation is one of the most prominent, important, and bothersome feature in many patients .
Clinical presentation • Irritative and obstructive voiding symptoms including urgency, frequency, hesitancy, and poor interrupted flow are associated with this syndrome in many patients. • Erectile dysfunction and sexual disturbances .
Clinical presentation • The syndrome becomes chronic after 3 months' duration. • The symptoms tend to wax and wane over time; • The impact of this condition on health status is significant.
