Prostatitis and Prostate Pain: Infection, Inflammation, CP/CPPS, Diagnosis and Treatment

01. What Conditions Are Included Under Prostatitis?

Why does the word “prostatitis” cause confusion?

The suffix “-itis” usually implies inflammation, so prostatitis sounds like one inflammatory disease of the prostate.

Clinically, however, the term covers several syndromes.

Some involve a confirmed bacterial infection of prostate tissue.

Others are chronic pain syndromes in which infection cannot be demonstrated and symptoms may involve the pelvic floor, urinary system, nervous system, sexual function and other pain mechanisms rather than the prostate alone.

Current EAU guidance therefore separates bacterial prostatitis from chronic pelvic pain syndrome rather than treating them as different stages of the same infection.

What is acute bacterial prostatitis?

Acute bacterial prostatitis is an infection of the prostate that usually begins suddenly.

Common features include:

• fever or chills;
• feeling systemically unwell;
• burning or painful urination;
• urinary frequency and urgency;
• difficulty emptying the bladder;
• pelvic, perineal or lower abdominal pain;
• and sometimes acute urinary retention.

Enterobacterales—particularly Escherichia coli—are among the predominant bacterial causes in current EAU guidance.

Unlike chronic pelvic pain syndromes, acute bacterial prostatitis is primarily an infectious disease and can occasionally progress to bacteremia, sepsis or a prostate abscess.

What is chronic bacterial prostatitis?

Chronic bacterial prostatitis is a persistent or recurrent bacterial infection involving the prostate.

Current EAU guidance describes chronic bacterial prostatitis as symptoms persisting for at least approximately three months.

The pattern is often less dramatic than an acute infection.

Symptoms can include:

• recurrent urinary tract infections;
• pelvic or perineal discomfort;
• penile or scrotal discomfort;
• pain around the lower abdomen or inner thigh;
• urinary frequency or urgency;
• burning during urination;
• and pain during or after ejaculation.

A particularly important clue is repeated urinary infection with the same or a similar organism.

What is CP/CPPS?

Chronic prostatitis/chronic pelvic pain syndrome is a different clinical problem.

The central feature is persistent or recurrent pelvic or genital pain—usually lasting for months—without an established bacterial infection that explains the symptoms.

Men may experience pain in the:

• perineum;
• penis;
• testicles or scrotal region;
• suprapubic area;
• rectal area;
• lower abdomen;
• or lower back.

Urinary symptoms, pain during or after ejaculation, sexual difficulties and symptom flares can occur alongside pain.

Modern chronic pelvic-pain research increasingly recognizes that the syndrome can involve multiple interacting mechanisms, including pelvic-floor muscle dysfunction, peripheral or central pain processing, urinary symptoms, organ-specific sensitivity and psychosocial factors.

The 2025 AUA male chronic pelvic pain guideline therefore emphasizes broad evaluation and multimodal, sometimes multidisciplinary management rather than assuming every patient has an occult infection.

What is asymptomatic inflammatory prostatitis?

Asymptomatic inflammatory prostatitis is inflammation discovered without the typical symptoms of prostatitis.

It may be identified incidentally in:

• prostate tissue;
• semen;
• prostate-related laboratory samples;
• or another investigation performed for a different reason.

Because the patient has no prostatitis syndrome, it should not automatically be treated like acute or chronic bacterial infection.

02. What Symptoms Can Prostatitis and Prostate Pain Cause?

Where is prostatitis pain usually felt?

Prostatitis-associated pain is not limited to one point directly over the prostate.

Depending on the syndrome, discomfort can be felt in the:

• perineum between the scrotum and anus;
• penis, particularly the tip or shaft;
• testicles or scrotal region;
• suprapubic lower abdomen;
• groin;
• rectal region;
• pelvic floor;
• lower back;
• and sometimes the inner thighs.

This distribution is particularly important in CP/CPPS because the pain may reflect a broader pelvic pain system rather than inflammation contained within the prostate.

What urinary symptoms can occur?

Prostatitis syndromes can overlap with lower urinary tract symptoms such as:

• burning or discomfort during urination;
• urinary frequency;
• urgency;
• weak urinary stream;
• hesitancy;
• interrupted flow;
• a sensation of incomplete emptying;
• and, in severe acute infection, urinary retention.

These symptoms are not unique to prostatitis.

They can also occur with bladder disorders, urethral disease, benign prostate enlargement and other urological conditions.

Can prostatitis cause pain with ejaculation?

Yes.

Pain during or after ejaculation is particularly recognized in chronic prostatitis and CP/CPPS.

Some men also report:

• reduced sexual activity because they anticipate pain;
• erectile difficulties;
• pelvic pain flares after ejaculation;
• or discomfort in the urethra, perineum or prostate region after sexual activity.

Sexual symptoms do not prove that the prostate itself is inflamed, but they are an important part of the clinical history.

How do acute bacterial prostatitis and CP/CPPS usually differ?

03. How Is Prostatitis Diagnosed?

Is there one test that diagnoses every type of prostatitis?

No.

The diagnostic approach depends on which prostatitis syndrome is suspected.

The first goal is often to answer a more fundamental question:

Is this an acute or chronic bacterial infection, or is this a chronic pelvic-pain syndrome without evidence of bacterial infection?

How is acute bacterial prostatitis evaluated?

Acute bacterial prostatitis is diagnosed primarily from the clinical presentation together with urine testing.

Current EAU guidance recommends:

• midstream urine dipstick testing;
• midstream urine culture;
• blood count and blood cultures in patients presenting with acute bacterial prostatitis;
• and assessment for complications when the clinical course warrants it.

A digital rectal examination may identify a very tender or swollen prostate, but deliberate prostate massage should not be performed in acute bacterial prostatitis.

How is chronic bacterial prostatitis confirmed?

The goal in chronic bacterial prostatitis is to demonstrate a bacterial source that localizes to the prostate.

Current EAU guidance supports the two-glass or four-glass localization test in appropriate patients.

The practical two-glass version compares:

• a urine specimen collected before prostate massage;
• with urine collected after prostate massage.

A meaningful increase in bacteria in the post-massage specimen can help localize infection to the prostate.

Depending on history, clinicians may also investigate atypical pathogens and recurrent urinary infections.

How is CP/CPPS diagnosed?

There is no single blood test, urine test, scan or prostate examination that proves CP/CPPS.

The diagnosis is based on the symptom pattern, examination and exclusion of other conditions that could better explain the pain.

A chronic pelvic-pain evaluation may assess:

• pain location, duration and triggers;
• urinary symptoms;
• sexual and ejaculatory symptoms;
• previous urinary infections;
• bowel symptoms;
• pelvic-floor muscle tenderness or overactivity;
• neurological or musculoskeletal symptoms;
• pain elsewhere in the body;
• sleep and functional impact;
• and the effect of persistent symptoms on mood and quality of life.

Current AUA guidance emphasizes that male chronic pelvic pain presentations are highly variable and may require evaluation beyond the prostate alone.

Why is the pelvic-floor examination important?

Some men with CP/CPPS have a myofascial pain component involving tender or overactive pelvic-floor muscles.

Pelvic-floor tenderness can reproduce familiar symptoms in some patients.

European chronic pelvic-pain experts have emphasized that myofascial pelvic pain is common enough that it should be actively assessed rather than overlooked.

Is imaging always required?

No.

Most prostatitis evaluations do not require routine CT, MRI or ultrasound simply because pelvic pain is present.

Imaging becomes more important when clinicians suspect:

• prostate abscess;
• urinary obstruction;
• stones;
• a structural urinary abnormality;
• a mass;
• or another condition that changes management.

Current EAU guidance allows transrectal ultrasound in selected bacterial-prostatitis cases when a prostate abscess needs to be excluded.

Should PSA be checked during active prostatitis?

PSA can rise during active prostate inflammation or infection.

Current EAU guidance states that PSA testing offers no practical diagnostic information for prostatitis itself and should be avoided during active prostatitis when the goal is to diagnose the inflammatory or infectious episode.

If PSA has already been measured and is elevated, the result must be interpreted in that context.

The relationship is explained in Can Prostatitis Raise PSA?.

04. How Is Prostatitis Treated?

How is acute bacterial prostatitis treated?

Acute bacterial prostatitis requires prompt antimicrobial treatment.

Management depends on illness severity, urine culture results, resistance patterns and whether complications are present.

A patient who is systemically unwell may require intravenous antibiotics and hospital-level care.

Current EAU guidance indicates that after infection parameters improve, treatment can generally transition to oral therapy, with the overall antimicrobial course typically continuing for several weeks.

Additional management may include:

• fluids;
• pain and fever control;
• management of urinary retention;
• and drainage or procedural management when an abscess is identified.

How is chronic bacterial prostatitis treated?

Chronic bacterial prostatitis is treated with antibiotics selected for the identified or strongly suspected organism and their ability to reach therapeutic concentrations in prostate tissue.

Treatment courses are generally longer than those used for simple bladder infections.

Current EAU guidance recommends several weeks of therapy for typical chronic bacterial prostatitis and emphasizes culture results, the responsible organism and local antimicrobial resistance.

If infections continue to recur, clinicians may also investigate:

• urinary obstruction;
• stones;
• anatomical abnormalities;
• incomplete bladder emptying;
• and other reasons bacteria may persist.

How is CP/CPPS treated?

CP/CPPS rarely has a single treatment that works for every patient because different men can have very different symptom drivers.

The 2025 AUA chronic pelvic pain guideline emphasizes a multimodal and sometimes multidisciplinary approach.

Depending on the individual pattern, management may include:

• education about chronic pelvic pain and symptom flares;
• lifestyle modification when specific activities trigger symptoms;
• pelvic-floor physical therapy when muscle tenderness or dysfunction is present;
• medication directed at bothersome urinary symptoms;
• pain-directed medication when appropriate;
• behavioral or psychological strategies that help reduce the functional impact of persistent pain;
• treatment of associated sexual symptoms;
• and selected additional therapies when first-line measures are insufficient.

The objective is not to imply that pain is “psychological.”

Chronic pain can persist through interactions between tissues, muscles, peripheral nerves, spinal pathways and central pain processing. Psychological distress can also worsen when symptoms persist, just as persistent pain can worsen sleep, mood and function.

When can pelvic-floor physical therapy help?

Pelvic-floor therapy can be particularly relevant when examination identifies:

• pelvic-floor muscle tenderness;
• muscle overactivity;
• trigger points;
• difficulty relaxing the pelvic floor;
• or reproduction of the patient’s pain when the muscles are examined.

Therapy in this setting is not simply “strengthening.”

A patient with an overactive painful pelvic floor may need techniques aimed at relaxation, coordination, myofascial treatment and normalization of muscle function rather than repetitive contraction exercises.

European pelvic-pain experts have specifically highlighted the importance of recognizing and treating myofascial pain in chronic pelvic pain syndromes.

What about urinary medicines?

Some men with CP/CPPS also have significant urinary symptoms.

Treatment can therefore include medication directed at the urinary component, particularly when hesitancy, weak flow or another voiding symptom is prominent.

The medication choice depends on the actual urinary problem rather than the prostatitis label alone.

Can chronic prostatitis improve?

Yes, but recovery patterns differ.

Acute bacterial infection often improves substantially when the responsible infection is treated appropriately.

Chronic bacterial prostatitis may require longer treatment and attention to recurrent infection.

CP/CPPS commonly behaves more like a chronic pain condition: symptoms may improve gradually, fluctuate, recur in flares or respond only after several contributing factors are addressed.

Improvement may therefore be measured not only by whether pain is completely absent, but also by:

• reduced pain intensity;
• fewer flares;
• better urinary function;
• improved sexual function;
• better sleep;
• return to exercise, work and social activity;
• and less interference from pain in daily life.
