Shockwave therapy for chronic prostatitis (CP/CPPS): evidence, risks

In short

• Cause: most chronic prostatitis is CP/CPPS, with no ongoing bacterial infection. Pain may come from tight pelvic floor muscles, over-sensitive nerves and local inflammation.
• Rule out first: shockwave is an option only after infection, stones and tumours are ruled out. Fever, visible blood in the urine, being unable to pass urine, a positive culture or an abnormal prostate examination are checked first.
• Sessions: on the perineal skin, usually with no cut, injection or anaesthesia. The device’s approved Chinese product information recommends 4 sessions, once a week. Here it is usually once a week, about 6–12 sessions, adjusted by the doctor, so it may differ from the product information.
• What to expect: the clearest evidence is short-term pain relief. Urinary results are less consistent; long-term effects are not established. A lasting cure, or no return of symptoms, cannot be guaranteed. It does not replace antibiotics for infection.
• Cost: Costs are explained at the consultation. You can also ask about costs on LINE before you come.

“Chronic prostatitis” does not always mean bacteria

Most men with chronic prostatitis actually have chronic prostatitis / chronic pelvic pain syndrome (CP/CPPS). The European Association of Urology (EAU) often calls it primary prostate pain syndrome (PPPS). There is usually pain in the pelvis or prostate area for at least three months, but no ongoing infection, tumour or other local disease that clearly explains it.

Common symptoms: a dull ache in the perineum (in front of the anus) or rectum; pain in the lower abdomen, groin, penis or around the testicles (ultrasound may be normal); worse with sitting, cycling or stress; frequent, urgent or burning urination; pain during or after ejaculation; effects on erections or desire; symptoms that come and go and affect work, sleep and sex life. If cycling mainly causes numbness without clear pain, see perineal numbness in cyclists (Chinese).

Why antibiotics did not help

If urine tests or cultures show no bacteria, more antibiotics may not treat the real source of the pain. CP/CPPS may involve tight pelvic floor muscles, over-sensitive nerves, changes in how the brain and spinal cord control pain, local inflammation, changes in small pelvic blood vessels, bladder emptying problems, and anxiety, poor sleep and stress. The European guideline explains that pain can continue after the first infection or irritation is gone, so treatment needs several approaches, not only the prostate or bacteria.

What is low-intensity shockwave therapy?

Low-intensity extracorporeal shock wave therapy (Li-ESWT) works from outside the body. A treatment head on the perineum sends low-energy sound pressure waves to the pelvic floor and around the prostate. Most men feel regular tapping, vibration or mild stinging.

It is not kidney-stone shockwave. That uses relatively high energy to break stones and may hurt more. This uses relatively low energy on the perineum to adjust pain, muscles and the local tissue environment, not to destroy tissue.

How might it help? Proposed mechanisms come mostly from animal and laboratory studies: changes in pain receptor sensitivity, pelvic floor muscle tension, VEGF (a blood-vessel growth factor) in prostate tissue, and inflammation signals. Pain makes muscles tighter and tight muscles cause more pain; shockwave therapy is one tool suggested for this cycle. These are only possible mechanisms. They do not mean the prostate regenerates, or that one course cures the condition for good.

Does it work? What the evidence says

• EAU guideline: shockwave therapy may have a short-term effect in primary prostate pain syndrome, with level of evidence 1b. It stresses combined treatment chosen for each man’s symptom pattern.
• American Urological Association (AUA) guideline, 2025: low-intensity shockwave therapy is one option to discuss with men with CP/CPPS, not a single standard treatment for every man.
• 2026 review: 8 randomised controlled trials, 455 patients in total. At about 12 weeks, the NIH Chronic Prostatitis Symptom Index (NIH-CPSI, a symptom questionnaire) fell on average by about 8.5 points more with Li-ESWT than with comparison treatment (sham treatment, or usual medicines only), mainly because pain scores fell.

But devices, energy, session numbers and patients varied widely, and results differed a lot between studies. Shockwave types have not been compared directly, so “focused”, “radial” or “multi-focal” does not show one device is better.

In summary: pain is most likely to improve; the total NIH-CPSI score improves short term in most studies; quality of life improves in some men; urinary results are less consistent; some studies saw better sexual function, but not in everyone; long-term effects are not established; a lasting cure cannot be guaranteed; it does not treat infection.

Who may consider it

After assessment, Li-ESWT may be worth discussing if:

• pelvic, perineal or prostate pain has lasted more than three months, and urine tests and cultures show no ongoing infection;
• the main problem is perineal pain, pain when sitting, or pain with ejaculation;
• medicines helped only partly, or you do not want to rely on painkillers long term;
• your pelvic floor muscles are tight, or you have muscle-and-fascia pain;
• you will complete regular sessions and track symptom scores, and accept it is a supporting treatment; a cure cannot be guaranteed.

Treatment is matched to each man’s pattern, not one course for everyone.

Do not go straight to shockwave if you have any of these

The cause must be checked first:

• fever, chills, or feeling weak all over;
• sudden, severe pain in the perineum;
• a positive urine culture or a positive test for a sexually transmitted infection;
• being completely unable to pass urine, or blood in the urine that you can see;
• repeated urinary tract infections;
• an abnormal prostate examination, or an abnormal PSA (prostate-specific antigen) result that needs more assessment;
• a possible urinary stone, narrowing of the urethra, or tumour of the urinary system;
• a wound or acute infection of the skin of the perineum;
• a blood clotting problem, or medicines that affect clotting.

CP/CPPS is a diagnosis of exclusion: bacterial infection, tumours and other clearly treatable diseases must be ruled out first.

Assessment, and how a course works

Assessment. Tests differ between men. Common parts: your pain pattern and triggers; urinary and sexual symptoms; the NIH-CPSI questionnaire; a urine test, and a culture if needed; STI risk and tests (see STI screening); prostate and pelvic floor examination; urine left after passing urine; PSA depending on age and risk; ultrasound or a flow test if needed. The aim is not to “prove inflammation”, but to find whether pain comes from infection, the bladder, urethra, muscles, nerves or other pelvic organs.

A session. NIH-CPSI and pain scores are recorded first. You lie on your back or in a position that exposes the perineum. The energy is adjusted to the device and to what you can tolerate, and the waves act around the prostate and pelvic floor. Afterwards you can usually return to daily activities. After the course, pain, urination and quality of life are assessed again.

Number of sessions. Approved product information: 4, once a week. This clinic: usually once a week, about 6–12, adjusted to your symptoms and response, so it may differ. Studies used 4 to 12, some weekly for 8 weeks; there is no agreed best energy or number, so “more pulses work better” is not a safe rule.

Your medicines. It is a physical treatment, not absorbed, with no dose to adjust for liver or kidney function. Tell the doctor about medicines you take by mouth.

When might you notice a change?

Usually not on the last day. After several weeks, some men slowly notice less frequent or shorter pain, longer sitting, milder pain after ejaculation, less worry, and better quality of life. Follow up for about 4 to 12 weeks after the course, then judge with the NIH-CPSI and daily function, not one session’s feeling. How long improvement lasts differs between studies and patients.

Shockwave is not the only treatment

• Antibiotics: for bacterial infection (positive culture, likely infection, or certain men at first treatment).
• Alpha-blockers: relax smooth muscle at the bladder outlet and prostate, for difficult urination or weak flow.
• Anti-inflammatory painkillers: short-term relief in flare-ups.
• Pelvic floor assessment and physical therapy: relax over-tight muscles, for pain when sitting, tender muscles or pain with ejaculation.
• Low-intensity shockwave: mainly pain, when simpler treatments helped only partly.
• Daily habits (Chinese): reduce triggers such as long sitting, stress, poor sleep or food.
• Psychological and pain treatment: ease the cycle of pain and fear, for long-term anxiety, poor sleep or low mood.

Should I train my pelvic floor? Know your type first; the two are treated in opposite ways. Too tight: deep pain after sitting, waiting before urine starts, discomfort after passing urine. CP/CPPS is more often this type; the aim is to relax, and strengthening (squeezing) exercises may make symptoms more noticeable. Too weak: leaking when abdominal pressure rises, poor control after prostate surgery, dribbling; the aim is to strengthen. Both is not rare; the main symptoms decide which comes first.

The European guideline recommends combined, pattern-based treatment. Shockwave therapy is one piece of the puzzle, not a replacement for medicines, rehabilitation and lifestyle changes.

Is it safe? Side effects and who should not have it

Randomised trials show that Li-ESWT is generally well tolerated, and serious treatment-related adverse events are uncommon. Possible short-lived reactions:

• tapping or stinging during treatment, and local soreness;
• brief redness or swelling of the skin;
• symptoms going up and down briefly early in the course;
• brief blood in the urine or semen (a few studies);
• mild skin injury (very rare).

Trials are small, report side effects differently, and long-term safety data are limited, so it is not zero risk.

Side effects in the approved Chinese product information: swelling, redness and haematoma (a collection of blood), bruising, and pain at the treatment site; skin changes in people who used steroids before. These usually settle within 5 to 10 days.

Contraindications in the approved Chinese product information of the device used here:

• blood clotting disorders (for example haemophilia);
• taking anticoagulants (blood thinners); the product information names phenprocoumon as an example;
• thrombosis (a blood clot), anywhere in the body;
• pregnancy;
• growth plates in children;
• corticosteroid (cortisone) use within 6 weeks before the first treatment.

If any of these apply, or you have any of the following, the problem is treated or clarified first, and then the doctor decides whether to go ahead:

• an open wound, broken skin or acute local infection at the treatment site;
• an untreated cancer, or a cancer under treatment, in the treatment area;
• an implanted device in the treatment area;
• taking antiplatelet medicines;
• being under 18 years old.

The product information states that its list does not cover every possible situation. Bring a list of your current medicines, especially anticoagulants and antiplatelet medicines.

Frequently asked questions

Medical risks and honest limits

Studies mainly include men without active infection; shockwave cannot replace antibiotics for bacterial prostatitis. It must not be promised as a lasting cure, “no relapse” or “prostate regeneration”. Fever, urinary retention, visible blood in the urine, repeated infections or abnormal results need other diseases ruled out first.

Normal tests do not mean the pain is imagined. The doctor works out how much infection, muscles, nerves, bladder habits and stress each contribute, then chooses medicines, rehabilitation, or adding shockwave. This usually gives clearer direction than changing antibiotics again and again.

Appointments and access

Consultations are conducted in Mandarin, and can also be conducted in English.
