Overview

Prostatitis encompasses a group of conditions involving inflammation of the prostate gland, which plays a crucial role in male reproductive health by producing fluid that nourishes and transports sperm. The condition is classified into four distinct categories by the National Institutes of Health (NIH), each with different causes, symptoms, and treatment approaches. Unlike prostate cancer or benign prostatic hyperplasia (BPH), prostatitis often affects younger men and can occur suddenly or develop gradually over time.

The four types of prostatitis include acute bacterial prostatitis (sudden bacterial infection), chronic bacterial prostatitis (recurring bacterial infection), chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS, the most common type without bacterial infection), and asymptomatic inflammatory prostatitis (inflammation without symptoms, discovered incidentally). CP/CPPS accounts for about 90% of prostatitis cases and remains one of the most challenging urological conditions to treat due to its unclear etiology and variable symptoms.

The impact of prostatitis extends beyond physical symptoms. Men with chronic prostatitis often experience depression, anxiety, and reduced quality of life comparable to those with other chronic conditions like diabetes or congestive heart failure. The condition can affect work productivity, relationships, and overall well-being. Understanding prostatitis is crucial not only for affected individuals but also for their partners and families, as the condition's chronic nature often requires long-term management strategies and lifestyle adjustments.

Symptoms

Prostatitis symptoms vary significantly depending on the type and severity of the condition. Symptoms can range from sudden and severe in acute bacterial prostatitis to chronic and fluctuating in CP/CPPS.

Common Urinary Symptoms

• Retention of urine - Difficulty starting urination or incomplete bladder emptying
• Frequent urination - Need to urinate often, especially at night (nocturia)
• Painful urination - Burning or stinging sensation during urination
• Blood in urine - May appear pink, red, or cola-colored
• Urgency - Sudden, compelling need to urinate
• Weak urine stream or interrupted flow

Pain and Discomfort

• Sharp abdominal pain - Often in the lower abdomen or pelvic area
• Lower abdominal pain - Persistent discomfort above the pubic bone
• Back pain - Particularly in the lower back
• Perineal pain - Between the scrotum and rectum
• Testicular or penile pain
• Pain during or after ejaculation

Sexual and Systemic Symptoms

• Impotence - Erectile dysfunction or reduced sexual desire
• Fever - Common in acute bacterial prostatitis
• Chills - Often accompanying fever in acute cases
• Painful ejaculation
• Flu-like symptoms in acute cases
• General malaise and fatigue

Type-Specific Symptom Patterns

Acute bacterial prostatitis: Sudden onset of severe symptoms including high fever, chills, severe pelvic pain, and marked urinary difficulties. This is a medical emergency requiring immediate treatment.

Chronic bacterial prostatitis: Recurring urinary tract infections with periods of improvement between episodes. Symptoms are generally less severe than acute form but persist over months.

Chronic prostatitis/CPPS: Pelvic pain for at least 3 months without evidence of infection. Pain may wax and wane, often triggered by stress, certain foods, or physical activities. Urinary symptoms vary in intensity.

Asymptomatic inflammatory prostatitis: No symptoms; discovered only through tests performed for other conditions, such as infertility evaluation or elevated PSA investigation.

Causes

The causes of prostatitis vary by type, ranging from bacterial infections to unknown factors. Understanding these causes is crucial for appropriate treatment selection.

Bacterial Causes

Acute and chronic bacterial prostatitis: Caused by bacterial infection of the prostate gland. Common bacteria include:

• Escherichia coli (E. coli) - Responsible for 50-80% of cases
• Klebsiella, Proteus, and Pseudomonas species
• Enterococcus species
• Sexually transmitted organisms (less common) - Chlamydia, gonorrhea

Bacteria typically reach the prostate through:

• Ascending urethral infection
• Reflux of infected urine into prostatic ducts
• Direct extension from rectal bacteria
• Hematogenous spread (through bloodstream)
• Following prostate biopsy or urinary catheterization

Non-Bacterial Causes (CP/CPPS)

The exact cause of CP/CPPS remains unclear, but several theories exist:

Autoimmune response: The immune system may mistakenly attack prostate tissue, causing inflammation without infection.

Nerve damage or dysfunction: Injury or inflammation of nerves in the pelvic area may cause pain signals without actual tissue damage.

Pelvic floor muscle dysfunction: Chronic tension or spasms in pelvic floor muscles can cause pain and urinary symptoms.

Psychological stress: Stress and anxiety may contribute to muscle tension and pain perception, creating a cycle of symptoms.

Previous infection: Initial bacterial infection may trigger ongoing inflammation even after bacteria are eliminated.

Contributing Factors

• Urinary reflux into prostate ducts
• Chemical irritation from urine components
• Structural abnormalities of the urinary tract
• Genetic predisposition
• Hormonal imbalances
• Lifestyle factors (diet, exercise, sexual activity)

Triggers and Exacerbating Factors

Various factors can trigger or worsen prostatitis symptoms:

• Dehydration or inadequate fluid intake
• Prolonged sitting or cycling
• Sexual activity or abstinence
• Certain foods (spicy, acidic, caffeinated, alcoholic)
• Cold weather
• Stress and emotional tension
• Heavy lifting or strenuous exercise

Risk Factors

Multiple factors increase the likelihood of developing prostatitis. Understanding these helps identify at-risk individuals and implement preventive strategies.

Demographic Factors

• Age: Can occur at any age but most common in men 30-50 years old
• Previous prostatitis: History of prostatitis increases risk of recurrence
• Family history: Genetic factors may play a role in susceptibility

Medical Conditions and Procedures

• Recent urinary tract infection (UTI)
• Urethral stricture or other urinary tract abnormalities
• Enlarged prostate (BPH)
• Recent prostate biopsy or urological procedures
• Use of urinary catheter
• Immunosuppression or compromised immune system
• Diabetes - Increases infection risk
• HIV/AIDS

Lifestyle and Behavioral Factors

• Sexual activity: Both high frequency and abstinence may increase risk
• Unprotected anal intercourse: Increases bacterial exposure
• Dehydration: Concentrated urine may irritate prostate
• Occupational factors: Jobs requiring prolonged sitting or vibration exposure
• Physical trauma: Injury to pelvic area or perineum
• Stress: High stress levels associated with CP/CPPS

Activities That May Increase Risk

• Long-distance cycling or horseback riding
• Heavy lifting with poor technique
• Prolonged driving or sitting
• Inadequate hygiene practices
• Holding urine for extended periods

Protective Factors

While less studied, certain factors may reduce prostatitis risk:

• Regular, moderate exercise
• Adequate hydration
• Stress management techniques
• Proper hygiene
• Prompt treatment of UTIs
• Safe sexual practices

Diagnosis

Diagnosing prostatitis requires a comprehensive approach combining medical history, physical examination, and various tests to determine the type and rule out other conditions.

Medical History

The diagnostic process begins with detailed questioning about:

• Symptom onset, duration, and severity
• Urinary symptoms and patterns
• Pain location, quality, and triggers
• Sexual function and any changes
• Previous UTIs or prostate problems
• Recent procedures or catheter use
• Current medications and allergies
• Lifestyle factors and stress levels

Physical Examination

Digital rectal examination (DRE): Essential for assessing the prostate. Findings may include:

• Tender, warm, swollen prostate (acute bacterial)
• Tender but normal-feeling prostate (chronic forms)
• Boggy or irregular texture
• Assessment of pelvic floor muscle tension

Additional examination: Includes abdominal palpation, genital examination, and assessment of lymph nodes.

Laboratory Tests

Urine tests:

• Urinalysis - Checks for infection, blood, or abnormalities
• Urine culture - Identifies specific bacteria and antibiotic sensitivity
• Two-glass or four-glass test - Localizes infection to prostate

Expressed prostatic secretions (EPS): Microscopic examination of prostate fluid obtained through massage during DRE.

Blood tests:

• Complete blood count (CBC) - Checks for infection signs
• PSA (prostate-specific antigen) - May be elevated but not diagnostic
• Blood cultures - In acute cases with fever
• Inflammatory markers (CRP, ESR)

Imaging Studies

• Transrectal ultrasound (TRUS): Visualizes prostate structure, abscesses
• MRI: Detailed imaging for complicated cases
• CT scan: If abscess or complications suspected
• Bladder ultrasound: Assesses post-void residual urine

Specialized Tests

• Urodynamic studies: Evaluate bladder and urethral function
• Cystoscopy: Direct visualization of urethra and bladder
• Semen analysis: In fertility evaluation
• NIH-CPSI questionnaire: Standardized symptom assessment tool

Differential Diagnosis

Conditions that must be distinguished from prostatitis include:

• Benign prostatic hyperplasia (BPH)
• Prostate cancer
• Bladder cancer
• Interstitial cystitis
• Urethral stricture
• Pelvic floor dysfunction

Treatment Options

Treatment for prostatitis varies significantly based on type and severity. A multimodal approach often provides the best outcomes, especially for chronic forms.

Acute Bacterial Prostatitis Treatment

Requires immediate aggressive treatment:

• Antibiotics: High-dose fluoroquinolones or trimethoprim-sulfamethoxazole for 2-4 weeks
• Hospitalization: For severe cases with systemic symptoms
• IV antibiotics: If oral medication not tolerated
• Pain management: NSAIDs, acetaminophen, or stronger analgesics
• Alpha-blockers: To improve urinary flow
• Supportive care: Hydration, rest, stool softeners

Chronic Bacterial Prostatitis Treatment

• Extended antibiotic therapy: 4-12 weeks of fluoroquinolones
• Alpha-blockers: Tamsulosin, alfuzosin for urinary symptoms
• Anti-inflammatory medications: To reduce pain and inflammation
• Prostate massage: Controversial but may help some patients
• Surgery: Rarely needed for recurrent infections

Chronic Prostatitis/CPPS Treatment

Most challenging to treat, requiring multimodal approach:

Medications:

• Alpha-blockers - First-line for urinary symptoms
