Physical Techniques to Remove Residual Stone Fragments in the Urinary System

Area of Science:

• Urology
• Nephrology
• Biomedical Engineering

Background:

• Renal and ureteral calculi treatment has advanced, but residual fragments (RF) remain a significant health concern.
• Novel physical techniques and extraction devices are under development to address RF removal from the urinary system.

Purpose of the Study:

• To summarize recent advancements in physical methods for the removal of residual fragments (RF) after urinary stone treatment.
• To highlight innovative therapies and their potential impact on the stone-free rate.

Main Methods:

• Literature review of recent studies on physical methods for RF removal.
• Analysis of in vivo experimental data on the safety and efficacy of novel techniques.

Main Results:

• Several innovative therapies, including external physical vibration, magnetic extraction, biocompatible stone adhesives, and ultrasonic propulsion, show potential for RF clearance.
• In vivo experiments indicate the safety and efficacy of these developing techniques.

Conclusions:

• Physical treatments for RF require optimization and further development.
• These innovative therapies offer a promising approach to enhance the efficiency of endourology and improve stone-free rates.
• Additional in vivo studies are necessary to validate the safety and efficacy of these physical treatment modalities.
