    A novel device with a steerable tip was used for nonoperative renal stone extraction via a nephrostomy tract. This new instrument offers improved stone trapping compared to traditional methods like the Dormia stone basket.

    Area of Science:

    • Nephrology
    • Urology
    • Medical Device Innovation

    Background:

    • Renal stones (kidney stones) are a common condition requiring treatment.
    • Percutaneous nephrostomy is an established approach for accessing kidney stones.
    • Existing stone extraction devices have limitations in maneuverability and stone capture.

    Purpose of the Study:

    • To describe a case of successful nonoperative renal stone extraction.
    • To introduce a newly constructed device for renal stone removal.
    • To highlight the advantages of the new device over existing methods.

    Main Methods:

    • A case of renal stone was managed nonoperatively.
    • A nephrostomy tract was utilized for access.
    • A novel device with a steerable tip was employed for stone extraction.

    Main Results:

    • Successful removal of a renal stone was achieved.
    • The newly constructed device demonstrated effective stone trapping.
    • The steerable tip facilitated precise manipulation and capture of the stone.

    Conclusions:

    • Nonoperative renal stone extraction is feasible using specialized devices.
    • The novel steerable-tip device offers enhanced capabilities for stone retrieval.
    • This approach may improve outcomes in managing renal calculi through nephrostomy tracts.
