It Comes As a Shock: Kidney Repair Using Shockwave Therapy

Area of Science:

• Nephrology
• Regenerative Medicine
• Biomedical Engineering

Background:

• Chronic kidney disease (CKD) poses a significant global health challenge with limited effective treatments.
• Low-intensity shockwave (LISW) therapy, a low-energy application of shockwave technology, is being explored for tissue regeneration.
• LISW has demonstrated potential in various tissues, including the kidney, primarily through stimulating neovascularization.

Purpose of the Study:

• To evaluate the potential of low-intensity shockwave therapy as a noninvasive treatment for renal diseases.
• To explore the mechanisms by which LISW may ameliorate kidney injury and preserve function.

Main Methods:

• LISW utilizes approximately 10% of the energy levels of therapeutic lithotripsy.
• The therapy stimulates mechanoreceptors in kidney cells, upregulating vascular endothelial growth factors (VEGF).
• LISW may also attract endothelial progenitor or stem cells to injured kidney tissue.

Main Results:

• LISW promotes angiogenesis, reduces renal hypoxia, inflammation, and fibrosis.
• These effects contribute to the preservation of renal function in preclinical models.
• Studies suggest potential benefits in models of renal artery stenosis, diabetic kidney disease, and other CKDs.

Conclusions:

• Low-intensity shockwave therapy is a potentially safe and tolerable noninvasive intervention for renal diseases.
• Further clinical studies are required to confirm its efficacy compared to existing treatments.
• LISW therapy represents a promising alternative approach for managing kidney diseases.
