Erectile dysfunction (ED), also known as impotence, is a prevalent urological issue. While the causes and treatment approaches for ED may vary between younger and older men, the underlying treatment principles generally remain consistent. Extracorporeal Shock Wave Therapy (ESWT), introduced since 2005 for treating ED, has been a successful method in our practice for a considerable period. This article aims to provide a comprehensive overview of penile ESWT, drawing from our own clinical experiences.
What is penile ESWT?
Extracorporeal Shock Wave Lithotripsy (ESWL), initially employed in the 1980s to disintegrate kidney stones using ultrasonic shock waves externally, has evolved into a treatment modality for various conditions. Over the past decade, similar shock waves have been utilized in addressing erectile dysfunction (ED) through Extracorporeal Shock Wave Therapy (ESWT), delivering shock waves externally to the penis. Specifically, Low-Intensity Extracorporeal Shock Wave Therapy (Li-ESWT) has been instrumental in treating ED, leveraging shock waves to stimulate penile tissue.
These shock waves have been administered globally since 2005 to treat ischemic heart tissues, inducing neovascularization and collateral vessel formation, thereby enhancing blood flow. Building upon this principle, Li-ESWT has been increasingly utilized since 2010 for individuals with vascular erectile issues.
What distinguishes Li-ESWT in ED treatment?
Li-ESWT, employed in ED therapy, possesses distinct characteristics contributing to erectile recovery. Key physical attributes of low-intensity shock waves include rapid propagation of acoustic energy in liquid or gaseous environments, characterized by a brief and intense positive peak pressure, with a speed of 1500m/sec in water.
How does Li-ESWT operate?
ESWT augments tissue blood supply, fostering tissue regeneration without causing significant harm. The effects include neovascularization, enhanced penile blood flow, tissue repair, stem cell migration to tissues, and alleviation of pain and inflammation.
Are there any complications or side effects associated with ESWT?
ESWT is generally devoid of serious complications or side effects. Minor discomfort such as mild pain, stinging, or itching during application, along with temporary redness post-procedure, may occur, though these effects are typically negligible.
