Prostatitis (Clinical)

Prostatitis is inflammation or an irritative condition of the prostate that presents as different syndromes: acute bacterial, chronic bacterial, chronic prostatitis/chronic pelvic pain, and asymptomatic. Bacterial prostatitis is easier to identify clinically and the management (antibiotics) is better established. Whether the condition is in an acute or chronic state determines the length of antibiotic treatment. The main diagnostic tools are history, physical examination, and work-up investigating the sources of infection (urinalysis and culture). Digital rectal examination is only recommended in patients with chronic prostatitis and not in acute bacterial prostatitis due to the risk of sepsis. Chronic pelvic pain syndrome is a diagnosis of exclusion and requires multimodal pain management with established patient expectations. The asymptomatic type is an incidental finding that is recognized when a patient has other urologic issues.

Prostatitis Prostatitis Prostatitis is inflammation or an irritative condition of the prostate that presents as different syndromes: acute bacterial, chronic bacterial, chronic prostatitis/chronic pelvic pain, and asymptomatic. Bacterial prostatitis is easier to identify clinically and the management (antibiotics) is better established. Prostatitis is inflammation Inflammation Inflammation is a complex set of responses to infection and injury involving leukocytes as the principal cellular mediators in the body’s defense against pathogenic organisms. Inflammation is also seen as a response to tissue injury in the process of wound healing. The 5 cardinal signs of inflammation are pain, heat, redness, swelling, and loss of function. Inflammation of the prostate Prostate The prostate is a gland in the male reproductive system. The gland surrounds the bladder neck and a portion of the urethra. The prostate is an exocrine gland that produces a weakly acidic secretion, which accounts for roughly 20% of the seminal fluid. gland that presents as different syndromes:

Epidemiology and etiology[13]

  • Prostatitis Prostatitis Prostatitis is inflammation or an irritative condition of the prostate that presents as different syndromes: acute bacterial, chronic bacterial, chronic prostatitis/chronic pelvic pain, and asymptomatic. Bacterial prostatitis is easier to identify clinically and the management (antibiotics) is better established. Prostatitis accounts for 2 million urology visits in the United States annually.
    • CPPS CPPS Chronic lower pelvic pain and inflammation of the prostate gland ≥ 3 months. May or may not be associated with infection Prostatitis is the most common diagnosis.
    • Incidence Incidence The number of new cases of a given disease during a given period in a specified population. It also is used for the rate at which new events occur in a defined population. It is differentiated from prevalence, which refers to all cases in the population at a given time. Measures of Disease Frequency of acute and chronic bacterial prostatitis Chronic bacterial prostatitis Chronic bacterial infection of the prostate with lower urinary tract symptoms Prostatitis is about 4%–5%.
  • Risk factors for acute and chronic bacterial prostatitis Chronic bacterial prostatitis Chronic bacterial infection of the prostate with lower urinary tract symptoms Prostatitis:
    • Inflammatory disorders: cystitis Cystitis Inflammation of the urinary bladder, either from bacterial or non-bacterial causes. Cystitis is usually associated with painful urination (dysuria), increased frequency, urgency, and suprapubic pain. Urinary tract infections (UTIs) or urethritis Urethritis Inflammation involving the urethra. Similar to cystitis, clinical symptoms range from vague discomfort to painful urination (dysuria), urethral discharge, or both. Urinary tract infections (UTIs)
    • Other genitourinary (GU) infections Infections Invasion of the host organism by microorganisms or their toxins or by parasites that can cause pathological conditions or diseases. Chronic Granulomatous Disease:
      • Gram-negative urinary tract Urinary tract The urinary tract is located in the abdomen and pelvis and consists of the kidneys, ureters, urinary bladder, and urethra.

Chronic Granulomatous Disease ( Escherichia coli Escherichia coli The gram-negative bacterium Escherichia coli is a key component of the human gut microbiota. Most strains of E. coli are avirulent, but occasionally they escape the GI tract, infecting the urinary tract and other sites. Less common strains of E. coli are able to cause disease within the GI tract, most commonly presenting as abdominal pain and diarrhea. Escherichia coli, Enterobacter Enterobacter Multidrug-resistant Organisms and Nosocomial Infections, and Serratia Serratia A genus of gram-negative, facultatively anaerobic, rod-shaped bacteria that occurs in the natural environment (soil, water, and plant surfaces) or as an opportunistic human pathogen. Acute Cholangitis) are responsible for 80% of cases in men > 35 years old.
      • STIs STIs Sexually transmitted infections (STIs) or sexually transmitted diseases (STDs) are infections that spread either by vaginal intercourse, anal sex, or oral sex. Symptoms and signs may include vaginal discharge, penile discharge, dysuria, skin lesions (e.g., warts, ulcers) on or around the genitals, and pelvic pain. Some infections can lead to infertility and chronic debilitating disease.

Diagnostic approach

Acute and chronic bacterial prostatitis Chronic bacterial prostatitis Chronic bacterial infection of the prostate with lower urinary tract symptoms Prostatitis are worked up similarly on initial presentation:

  • Urinalysis Urinalysis Examination of urine by chemical, physical, or microscopic means. Routine urinalysis usually includes performing chemical screening tests, determining specific gravity, observing any unusual color or odor, screening for bacteriuria, and examining the sediment microscopically. Urinary Tract Infections (UTIs) in Children (UA) revealing:[47]
    • Pyuria Pyuria The presence of white blood cells (leukocytes) in the urine. It is often associated with bacterial infections of the urinary tract. Pyuria without bacteriuria can be caused by tuberculosis, stones, or cancer. Urinary tract infections (UTIs): elevated WBCs
    • May be nitrite Nitrite Salts of nitrous acid or compounds containing the group NO2-. The inorganic nitrates of the type mno2 (where m=metal) are all insoluble, except the alkali nitrites. The organic nitrites may be isomeric, but not identical with the corresponding nitro compounds. Kidney Function Tests positive
    • May be leukocyte esterase Leukocyte esterase Kidney Function Tests positive
  • Midstream urine culture Urine culture Urinary tract infections (UTIs) identifies the organism and determines sensitivity.[6]
  • STI STI Sexually transmitted infections (STIs) are infections that spread either by vaginal intercourse, anal sex, or oral sex. Symptoms and signs may include vaginal discharge, penile discharge, dysuria, skin lesions (e.g., warts, ulcers) on or around the genitals, and pelvic pain. Some infections can lead to infertility and chronic debilitating disease.

Treatment protocols may vary based on locale. The following recommendations are based on North American, UK, and European guidelines.

Treatment

Acute bacterial prostatitis Acute bacterial prostatitis Acute bacterial infection of the prostate with lower urinary tract symptoms Prostatitis:[47,9] 

  • Antibiotics with high level of penetration Penetration X-rays into the prostate Prostate The prostate is a gland in the male reproductive system. The gland surrounds the bladder neck and a portion of the urethra. The prostate is an exocrine gland that produces a weakly acidic secretion, which accounts for roughly 20% of the seminal fluid. tissue (generally given for 14 days)
  • Strongly consider inpatient admission:[6] 
    • Failed outpatient management
    • Not able to tolerate oral medications
    • Urinary retention Urinary retention Inability to empty the urinary bladder with voiding (urination). Delirium
    • Resistance Resistance Physiologically, the opposition to flow of air caused by the forces of friction. As a part of pulmonary function testing, it is the ratio of driving pressure to the rate of air flow. Ventilation: Mechanics of Breathing risk factors:
      • Recent fluoroquinolone use
      • Recent transrectal or transurethral prostatic manipulation
    • Systemically ill or septic
  • Severe urinary obstructive symptoms:
    • Avoid Foley catheter insertion due to risk of sepsis Sepsis Systemic inflammatory response syndrome with a proven or suspected infectious etiology. When sepsis is associated with organ dysfunction distant from the site of infection, it is called severe sepsis. When sepsis is accompanied by hypotension despite adequate fluid infusion, it is called septic shock. Sepsis and Septic Shock
    • Consult urology and, if needed, proceed with suprapubic catheter insertion.

Chronic bacterial prostatitis Chronic bacterial prostatitis Chronic bacterial infection of the prostate with lower urinary tract symptoms Prostatitis:[4,8,9] 

  • Antibiotic therapy covering gram-negative organisms
  • Prolonged course of antibiotics for about 8–12 weeks
  • Management of urinary obstruction as needed
  • Alpha-blockers Alpha-blockers Drugs that bind to but do not activate alpha-adrenergic receptors thereby blocking the actions of endogenous or exogenous adrenergic agonists. Adrenergic alpha-antagonists are used in the treatment of hypertension, vasospasm, peripheral vascular disease, shock, and pheochromocytoma. Antiadrenergic Drugs may reduce the risk of recurrence.

Chronic prostatitis Prostatitis Prostatitis is inflammation or an irritative condition of the prostate that presents as different syndromes: acute bacterial, chronic bacterial, chronic prostatitis/chronic pelvic pain, and asymptomatic. Bacterial prostatitis is easier to identify clinically and the management (antibiotics) is better established.
