ABSTRACT

Introduction: Current treatment for erectile dysfunction (ED) mostly attempts to improve erectile function with limited impact on altering the underlying pathophysiology of ED. Recent animal experiments have supported the notion that low intensity extracorporeal shockwave therapy (LIESWT) significantly improves penile hemodynamics and might induce structural changes that regenerate penile tissue.

Areas covered: This review article provides an overview of the basic mechanics and clinical studies pertaining to LIESWT and its use in the field of ED. We identify several key aspects of LIESWT and compare contemporary LIESWT machines and their clinical outcomes.

Expert commentary: There is emerging and strong literature to support the use of LIESWT in men with ED, with many clinical studies reported encouraging results in the use of LIESWT with improved erectile function, good safety records, and short-term durability. However, there is a need to define which subgroup of ED population is best suited and the LIESWT treatment protocol including LIESWT template, modality of shock waves energy, emission frequency, and total energy delivery. More stringent randomised controlled trials are warranted before there is widespread acceptance of this LIESWT technology as the standard of care in ED.
