1. What Is the Primary Goal of Shock Wave (ESWT) Therapy for Peyronie’s Disease?
In Peyronie's disease, shock wave therapy (ESWT) is a completely non-surgical and non-invasive method that involves applying external acoustic energy to the hard fibrotic plaques in the tunica albuginea of the penis.
The primary goals of this treatment are as follows:
To quickly relieve pain
To induce micro-level remodeling on the fibrotic plaque
To increase the elasticity of the plaque tissue and reduce its stiffness
To slow the progression of the disease
Improving erection quality by positively affecting vascular tissue
Laying the groundwork to enhance the effectiveness of other treatments
For this reason, ESWT is not a miracle cure on its own for Peyronie’s disease; however, when used on the right patient at the right time, it is a very valuable treatment option.
2. The Scientific Mechanism of Action of ESWT in Peyronie’s Disease
In Peyronie’s disease, the plaque tissue is very different from normal skin or muscle tissue. It is stiffer, less elastic, and has reduced blood flow. The effect of shock wave therapy is shaped precisely by these differences.
a) Microtrauma and Remodeling
ESWT creates controlled trauma at the microscopic level within the plaque.
Thanks to this microtrauma:
• The plaque tissue begins to break down and thin
• The body produces tissue-regeneration signals to heal this area
• Fibrosis becomes less rigid, and the tissue becomes more flexible
As a result of this treatment, a dramatic improvement in the curvature is not expected; rather, it is expected that severe curvatures will not progress and that mild curvatures will become less pronounced.
b) Inhibition of Pain Transmission
In the acute phase of Peyronie’s disease, pain originates from the nerve endings surrounding the plaque.
ESWT waves modulate the nerve fibers that carry pain signals:
• Significantly reduce pain starting from the first sessions
• Inhibit muscle and tissue contractions
• Eliminate sensitivity experienced during intercourse
This is the area where ESWT produces the strongest and most consistent results.
c) Neovascularization: New Blood Vessel Formation
Shock waves increase the formation of microvessels in the penis.
As a result:
• Oxygenation around the plaque increases
• Tissue healing is accelerated
• Erectile function is improved
This effect offers a significant advantage, particularly for patients with Peyronie’s disease who also have erectile dysfunction.
d) Modulation of the Inflammatory Response
ESWT suppresses the inflammatory process active during the acute phase of Peyronie’s disease. This allows the disease to progress to the stable phase in a more controlled manner and with less tissue damage.
3. For Which Patients with Peyronie's Disease Is ESWT More Effective?
The most critical aspect of shock wave therapy is proper patient selection.
Acute Phase (First 6–18 Months) – Maximum Benefit
• Pain is present
• Plaque hardening is recent
• Curvature has not yet fully stabilized
• High potential for tissue remodeling
The most pronounced effect of ESWT is observed during this period.
Hafif–Orta Eğrilik Derecesi (< 40°)
Enerjinin plak üzerine etkisi daha homojendir. Bu hastalarda plak yumuşaması ve ağrı azalması ile birlikte ilişki kalitesi belirgin artar.
Patients with Pain Complaints
The most dramatic result of ESWT is rapid pain relief. According to the literature, this group has the highest satisfaction rate.
Patients with Peyronie’s Disease and Erectile Dysfunction
Because it increases blood flow to the penis, it is quite beneficial for men with mild to moderate erectile dysfunction.
4. In Which Patients Does ESWT Yield More Limited Results?
Severe Scoliosis (> 60–70°)
In these patients, the ability of shockwave therapy to correct angular deformity is limited.
However:
• Pain relief
• Softening of the tissue
• Reduction in deformities that may occur after surgery
Benefits such as these can be observed.
Calcified Plaque
Energy distribution is different in calcified plaque tissue. While it is difficult to produce significant changes on its own, it still provides benefits when used in combination with other treatments.
Long-Term Chronic Disease
If the plaque has fully stabilized and there has been no change for more than 18 months, ESWT produces limited effects on the tissue. Nevertheless, it is beneficial in terms of pain reduction and increased stiffness.
5. How Is ESWT Treatment Administered? Steps of the Procedure
The treatment is extremely comfortable and usually lasts 15–20 minutes.
Steps to follow:
The patient is placed on the examination table
The plaque area is identified
A conductive gel is applied to the penis
The shock wave tip is brought into contact with the plate and the surrounding area
Energy is supplied at an average of 1,500–3,000 pulses
At the end of the session, the patient immediately returns to their daily life
No anesthesia is required, and there is no pain.
6. ESWT Treatment Protocol (Number of Sessions and Intervals)
The standard protocols in the Turkish and international literature are as follows:
• 1 or 2 sessions per week
• A total of 4–6 weeks, or 6–12 sessions
• A second course may be administered as needed
• One course is generally sufficient during the acute phase
• Combined courses may be necessary during the chronic phase
7. Measures of Success for ESWT Treatment
The following parameters can be evaluated after treatment:
• Pain score
• Degree of curvature
• Softness of the plaque tissue
• Quality of erection
• Changes felt during intercourse
• Overall penile function
• Patient satisfaction
In particular, a reduction in pain is the earliest sign of success.
8. The Most Significant Benefit of ESWT Treatment: Pain Management
Pain during the acute phase of Peyronie’s disease:
• Symptoms subside very quickly with ESWT
• Most patients experience significant relief within the first 1–3 sessions
• The pain may disappear completely
Thanks to this effect, patients stop avoiding intimacy, and their psychological burden is eased.
9. Effects on the Plate: Softening, Thinning, and Stabilization
ESWT does not completely eliminate plaque tissue; however:
• The elasticity of the hard tissue increases
• The plaque may take on a flatter structure
• The edges of the plaque become softer
• The progression of the curvature stops
Achieving a stable phase of the disease is one of the main goals of treatment.
10. Level of Influence on Curvature
Realistically:
• During the acute phase, the progression of scoliosis stops
• In mild cases (20–30 degrees), minor improvements may occur
• In advanced cases, angular correction is limited
• Results are enhanced when traction is combined with PRP or exosomes
In other words, ESWT is not a “scoliosis correction treatment” in and of itself; however, it is very valuable for stabilizing the curvature.
11. Effect on Erectile Quality
The vascular structure of the penis benefits significantly from ESWT.
Effects:
• Increased microvascular formation
• Improved tissue oxygenation
• Increased penile sensitivity
• Erections may become firmer
If Peyronie’s disease is accompanied by mild vascular erectile dysfunction, ESWT generally provides a dual benefit.
12. The Role of ESWT in Surgical Decision-Making
ESWT in some patients:
• May delay the need for surgery
• May make surgery less invasive by halting the progression of the curvature
• When combined with traction and injection therapies, may help avoid surgery
However, it cannot replace surgery in cases of severe curvature or significant loss of function.
13. Advantages of ESWT
• Completely non-surgical
• No recovery time required
• Minimal pain and side effects
• Sessions are short and comfortable
• May help improve erectile function
• Return to daily life immediately after treatment
• Well-suited for combination therapies
• Highly effective in managing the disease during the acute phase
14. Disadvantages of ESWT
• Not all patients respond the same way
• It is not sufficient on its own for severe scoliosis
• Its effectiveness decreases in the chronic phase
• It promotes plaque remodeling rather than plaque loss
• Several sessions are required
• Managing patient expectations is important
15. When Should Shock Wave Therapy Begin?
The most appropriate time is during the acute phase. That is:
• The first 6–18 months
• The period when pain is present
• The period when the curvature is variable
• The period when the brace has not yet fully stabilized
At this stage, treatment both relieves pain and controls the progression of the deformity.
16. Treatments That Can Be Combined with ESWT
The best results are usually achieved with combination protocols. For example:
• PRP therapy
• Exosome/stem cell-based therapies
• Pentoxifylline or L-arginine
• Hyaluronidase injections
• Traction device
• Penile physical therapy
These combinations are particularly effective during the acute phase.
17. Side Effects: One of the Safest Treatments for Peyronie's Disease
Side effects are generally mild and temporary:
• Mild redness
• Temporary tenderness
• Mild swelling
• Very rarely, bruising
No serious side effects have been reported.
18. Patient Groups for Whom ESWT Cannot Be Performed
• Open wound at the application site
• Active infection
• Severe bleeding disorder
• Anticoagulant therapy requiring careful monitoring
19. Post-ESWT Precautions
• A return to normal daily activities is possible on the same day
• Extremely hot showers are not recommended
• Sexual intercourse on the same day is not a problem for most patients
• Trauma to the penis should be avoided
• Combining this procedure with traction and medication is beneficial
20. Expectations and Realities of ESWT Treatment
• Pain reduction: very high success rate
• Tissue softening: marked
• Correction of curvature: mild–moderate, varies by patient
• Improvement in erectile function: common
• Halting disease progression: strong effect in the acute phase
• Does not replace surgery
• Proper patient selection is the key determinant of success
21. Conclusion and Treatment Recommendations
Shockwave therapy (ESWT) for Peyronie’s disease:
• Rapidly reduces pain
• Softens plaque tissue
• Halts the progression of curvature
• Supports erections
• Is a safe, non-surgical method.
It is particularly valuable when administered during the acute phase. During the chronic phase, good results can be achieved by combining it with other treatments.
