    A new prototype apparatus for microexplosion lithotripsy was developed. This device successfully crushed model stones in a pig bladder, enabling their removal via aspiration.

    Area of Science:

    • Biomedical Engineering
    • Urology
    • Minimally Invasive Surgery

    Background:

    • Urinary bladder stones (calculi) pose a significant clinical challenge.
    • Current lithotripsy methods have limitations in efficacy and safety.
    • Novel approaches for stone fragmentation and removal are needed.

    Purpose of the Study:

    • To develop and test a prototype apparatus for microexplosion lithotripsy in the urinary bladder.
    • To evaluate the feasibility of using this apparatus for stone fragmentation and removal.

    Main Methods:

    • Development of a prototype microexplosion lithotripsy device.
    • In vitro testing using a model calculus within a pig bladder.
    • Assessment of stone fragmentation and subsequent removal by aspiration.

    Main Results:

    • The prototype apparatus was successfully developed.
    • Model calculi within a pig bladder were effectively fragmented by the microexplosion lithotripsy.
    • Fragmented stone material was successfully removed via aspiration.

    Conclusions:

    • The developed prototype apparatus shows promise for microexplosion lithotripsy in the urinary bladder.
    • This novel approach may offer a new option for treating bladder stones.
    • Further research and development are warranted to optimize the technology for clinical application.
