Summary
Shock waves, distinct from ultrasound, offer mechanical therapeutic effects without heat. Initially used for kidney stone disintegration in urology, their potential in orthopedics for bone and soft tissue changes is now actively researched.
Area of Science:
- Biomedical Engineering
- Medical Physics
- Orthopedics
Background:
- Biological effects of ultrasound are thermal and mechanical.
- Shock waves provide a non-thermal mechanical effect for medical applications.
- Shock wave therapy originated in urology for breaking kidney stones.
Purpose of the Study:
- To review the similarities and differences between shock waves and ultrasound.
- To describe therapeutic shock wave generation.
- To discuss shock wave mechanisms for therapeutic effects.
Main Methods:
- Comparative analysis of shock waves and ultrasound.
- Description of shock wave source characteristics.
- Review of shock wave mechanisms in biological tissues.
Main Results:
- Shock waves exert mechanical, not thermal, effects.
- Therapeutic shock waves are generated by specific sources.
- Shock waves induce stone fragmentation and tissue changes.
Conclusions:
- Shock wave therapy has expanded from urology to orthopedics.
- Understanding shock wave characteristics and mechanisms is crucial for therapeutic applications.
- Further investigation into orthopedic applications is ongoing.

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

Electroconvulsive therapy (ECT), or shock therapy, remains a critical biomedical intervention for severe, treatment-resistant depression. While its origins can be traced back to Hippocrates' observations that malaria-induced convulsions alleviated mental illness, modern ECT has evolved significantly from its earlier, more primitive applications. First introduced in 1938 by Ugo Cerletti and his colleagues, ECT involves inducing controlled seizures using electrical currents. In its early...

Management of renal calculi focuses on effective strategies like tailored nutrition and hydration therapy. Adjusting diet and fluid intake reduces stone formation and recurrence, making these interventions simple yet powerful in kidney stone prevention and management.Understanding Kidney StonesKidney stones form when calcium, oxalate, uric acid, and cystine concentrate and crystallize in urine. Factors contributing to their formation include genetic predisposition, certain medical conditions,...

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

The diagnosis of renal calculi involves several imaging techniques, including non-contrast CT scans and ultrasound. These methods help visualize kidney stones, assess their size and location, and detect possible obstructions. Additionally, Measuring urine pH is useful for diagnosing specific stone types, such as struvite (alkaline pH) and uric acid stones (acidic pH). Cystine stones are primarily linked to cystinuria, a genetic condition. A urinalysis helps detect blood in the urine (hematuria)...
