What Is ESWT? Shock Wave Therapy in Urology

What Is ESWT? Shock Wave Therapy in Urology

The Scientific Basis of ESWT and How It Works

ESWT (extracorporeal shock wave therapy) works by delivering high-energy sound waves generated outside the body to a specific focal point. These sound waves create a mechanical stress within the tissue that produces a biological response. Unlike ultrasound waves, shock waves have a much higher pressure amplitude and a very short rise time. This allows the energy to reach deep into the tissue without damaging it and to produce a micro-trauma effect only in the targeted area. But how does that micro-trauma bring about healing?

At the centre of the process lies angiogenesis, the formation of new blood vessels. In urological applications, the shock waves delivered to the cavernous tissue of the penis not only widen the vessels already present but also trigger the release of proteins such as vascular endothelial growth factor (VEGF), stimulating the formation of new microvascular networks. This means a lasting increase in blood flow to the penis. Given that erectile difficulty usually has a vascular cause, it is clear that ESWT addresses the root of the problem directly. Clinical research in Turkey and elsewhere has shown that low-intensity shock wave therapy (Li-ESWT) supports tissue regeneration and activates cell proliferation.

What Is the Difference Between Focused and Radial ESWT?

Two main technologies are used in ESWT: focused and radial shock waves. In urological and andrological treatment, and particularly in erectile dysfunction and Peyronie's disease, focused ESWT is regarded as the gold standard. Focused waves concentrate the energy at a specific point deep within the tissue, allowing it to reach the deep structures of the corpora cavernosa, the blood-filled chambers within the penis. Radial ESWT spreads more superficially and is generally used in physiotherapy for musculoskeletal problems. Specialists such as Dr. Taylan Yanar recommend that high-technology focused devices always be used in urological cases, where penetration beneath the surface of the tissue is critical.

Mechanotransduction and the Cellular Response

The effect of shock waves on tissue is explained by mechanotransduction — the conversion of a mechanical stimulus, in this case the shock wave, into biochemical signals inside the cell. When receptors on the cell membrane detect these waves, the release of nitric oxide (NO) increases. Nitric oxide is the key molecule that relaxes the blood vessels and allows blood to be pumped more freely into the tissue. The process also encourages stem cells to migrate to the area, supporting the repair of damaged tissue. This deep cellular activation is what most clearly distinguishes ESWT from medication, which only suppresses symptoms.

ESWT for Erectile Dysfunction

Erectile dysfunction (ED) is the inability to achieve or maintain an erection sufficient for intercourse. In most cases factors such as diabetes, high blood pressure, obesity and smoking lead to blockage or loss of elasticity in the blood vessels of the penis. The oral medication conventionally used — PDE5 inhibitors — widens the vessels only temporarily. ESWT, by contrast, aims to produce lasting physiological improvement in what is known as vasculogenic ED, erectile difficulty of vascular origin. Because it requires no surgery, the treatment has been described as a non-invasive revolution.

Li-ESWT (low-intensity extracorporeal shock wave therapy) protocols generally consist of between six and twelve sessions depending on the patient's condition. In each session thousands of shock waves are delivered to different anatomical areas of the penis. These waves awaken dormant stem cells within the tissue and improve endothelial function — the health of the inner lining of the blood vessels. Success depends on the patient's age and on the severity of any underlying illness, but in men with mild to moderate erectile difficulty in particular the results are encouraging, with rates of 70 to 80 per cent. Some patients who had not responded to medication have regained the capacity for erection after ESWT, either with medication or without it.

Who Is ESWT Suitable For?

ESWT is particularly well suited to men whose erectile difficulty is of vascular origin. Diabetic patients, those with cardiovascular disease and men who notice a decline in sexual function with age benefit most. It is also an excellent alternative for men who wish to improve sexual performance but prefer not to take medication because of its systemic side effects, such as headache, flushing or heartburn. Because the treatment is entirely painless it requires no anaesthetic, and the patient can return to work and social life immediately afterwards. At our clinic in İzmir the patient's vascular structure is examined by Doppler ultrasound so that suitability for ESWT can be confirmed.

How Lasting Is the Treatment?

Many patients ask how long the effect lasts. Clinical research indicates that the effect of ESWT continues for one to two years, and that this period can be extended further when supported by a healthy lifestyle — good nutrition and regular exercise. Unlike medication, ESWT removes the need to plan ahead of every sexual encounter, because the natural mechanism of the penis has been repaired. As awareness of this has grown, men have increasingly turned to fundamental treatments such as ESWT rather than temporary solutions.

ESWT in Peyronie's Disease and Chronic Pelvic Pain Syndrome

Peyronie's disease is a progressive condition characterised by the formation of hard plaques (fibrosis) within the tissues of the penis, causing curvature, pain and shortening. It can place considerable psychological pressure on a man. ESWT is highly effective in the acute phase of the disease in particular — the period when pain is at its most intense. The shock waves disrupt the structure of these hardened plaques, increasing the elasticity of the tissue and reducing inflammation. Although surgery is needed for severe curvature, ESWT applied in the early period can halt the progression of the disease and eliminate the pain completely.

Chronic pelvic pain syndrome (CPPS), or chronic prostatitis, is a condition that is difficult to treat and reduces quality of life, involving burning in the urinary tract and a constant sensation of pressure in the pelvic area. In patients who do not respond to antibiotic treatment, ESWT is used to release spasm in the pelvic floor muscles and improve microcirculation. In the ESWT protocols applied by Dr. Taylan Yanar in İzmir, shock waves delivered to the pelvic region appear to modulate pain signals and accelerate tissue healing, helping patients to return to a life without pain.

The Effect on Peyronie's Plaques

Peyronie's plaques form through the irregular accumulation of collagen fibres. ESWT waves weaken the cross-links between these fibres and so soften the plaque. This is a critical step either in preparing the penis for surgery or in removing the need for surgery altogether. Because the shock waves also increase blood flow to the area, they assist the body's own enzymes in clearing the plaques. The use of ESWT in the treatment of Peyronie's disease has become a well-established approach supported by scientific publication in recent years.

Chronic Prostatitis and Quality of Life

Patients with chronic prostatitis generally complain of prolonged antibiotic use. ESWT offers a drug-free alternative. The shock waves reduce the sensitivity of the nerve endings around the prostate (desensitisation) and relieve muscular tension in the area. Patients generally report a marked reduction in pain and an improvement in urination by the third or fourth session. Because it has no side effects, the method can be used safely in long-standing cases.

The ESWT Treatment Process, Application and Safety

One of the greatest advantages of ESWT is that it is an outpatient procedure that does not disturb the patient's comfort. A typical session lasts around fifteen to twenty minutes. A special gel is applied to the penis and the head of the device is moved over the relevant areas. Patients generally feel a mild tingling or hear a tapping sound, but the sensation is by no means unbearable pain. At our clinic in İzmir the full technical infrastructure is in place to make the treatment process as comfortable as possible.

In terms of safety, ESWT has no known serious side effects. Mild redness or local tenderness may occasionally be seen afterwards, but this resolves on its own within a few hours. There is no need to abstain from sexual activity during the course of treatment; on the contrary, an active sexual life is encouraged so that the effects of treatment can be observed. Applied according to international protocols, the method carries none of the risks of infection, bleeding or anaesthesia associated with invasive surgery.

How Many Sessions Are Needed and What Results Can Be Expected?

Although the protocol varies from patient to patient, a course of six sessions, generally one or two per week, is usual. In severe cases this may be increased to twelve. The first effects are generally felt after the third session. Because tissue repair and the formation of new blood vessels are biological processes that take time, however, the full result reaches its peak two to three months after the end of treatment. During this period the body continues to repair itself in response to the stimulus the shock waves have provided.

Who Should Not Have ESWT?

Although the method is safe, there are situations in which ESWT is not recommended. Care should be taken, or treatment postponed, in patients with an active urogenital infection, a suspected malignant tumour in the penile area or a severe blood clotting disorder. For this reason examination by a specialist and a detailed medical history are essential before treatment begins. Dr. Taylan Yanar assesses every patient individually in order to establish the most appropriate treatment plan.

Frequently Asked Questions

Will I Feel Pain During ESWT Treatment?

ESWT is generally painless, or involves only minimal discomfort. During the session patients feel a light tapping or vibration against the penis, caused by the sound waves produced by the device coming into contact with the tissue. For most patients this is easily tolerated and requires no local or general anaesthetic. The patient can get up from the table and return to daily activity as soon as the session ends. If any significant discomfort is felt, the energy level of the device can be adjusted immediately by the specialist to suit the patient.

When Does ESWT Start to Work and How Long Does It Last?

Improvement generally begins after the third or fourth session, and the clearest results appear two to three months after the final one.

The effects vary according to the patient's biology and the severity of the problem, but improvements in the quality of erection generally begin to be observed after the third or fourth session. The angiogenesis that is the real purpose of the shock waves continues after treatment has ended. The clearest and most lasting results generally appear two to three months after the final session. Clinical data indicate that this improvement can last for one to two years or longer when supported by lifestyle changes such as stopping smoking and taking regular exercise.

Does ESWT Have Side Effects?

Because ESWT is non-invasive, its side effect profile is very low. It has no known systemic side effects, which makes it safe for patients with heart conditions or high blood pressure who cannot take medication. Very occasionally mild redness, bruising or temporary tenderness may be seen at the site of application. These signs generally disappear entirely within the first 24 hours. The procedure does not damage the internal structure or the nerves of the penis; on the contrary, it triggers a biological repair mechanism that supports the health of the tissue.

Which Is More Effective, ESWT or Erection Tablets?

Erection tablets (PDE5 inhibitors) provide a temporary increase in blood flow only while they are being taken. They do not treat the problem; they conceal the symptom. ESWT addresses the origin of the problem, repairing damaged vessels and promoting the formation of new ones. In this sense ESWT is a curative treatment, while tablets are a supportive measure. Many patients no longer need medication after ESWT, or are able to reduce the dose they take. ESWT also has none of the side effects associated with medication, such as headache, digestive problems or visual disturbance.

Does ESWT Correct the Curvature Completely in Peyronie's Disease?

The main achievement of ESWT in Peyronie's disease is the relief of pain and the softening of the plaques, halting the progression of the condition. Applied in the acute or early period in particular, it can reduce plaque volume and so produce a degree of improvement in the curvature. In very advanced cases with calcified plaques and severe curvature, however, ESWT alone may not be sufficient and surgery may be required. Even then, softening the plaques with ESWT beforehand can improve the outcome of the operation. A specialist andrologist will assess the combined treatment options appropriate to the individual patient.
