    Summary
    This summary is machine-generated.

    A new flexible nephroscope aids difficult kidney stone removal, offering atraumatic inspection and superior visualization. Surgeons found this flexible instrument superior to rigid scopes for locating and removing calculi, with no complications reported.

    Area of Science:

    • Urology
    • Minimally Invasive Surgery
    • Medical Instrumentation

    Background:

    • Managing complex kidney stone cases, including staghorn or recurrent calculi, often requires advanced visualization techniques.
    • Chronic nephrostomy cases present unique challenges for intrarenal inspection.

    Purpose of the Study:

    • To evaluate the efficacy and safety of a new flexible nephroscope for intrarenal inspection in challenging surgical scenarios.
    • To compare the performance of the flexible nephroscope against traditional rigid scopes.

    Main Methods:

    • A new flexible nephroscope with a 16F tip was utilized in 30 patients undergoing surgical procedures for kidney stones.
    • Procedures included open surgery (27 patients) and nephrostomy (3 patients).
    • Surgeons' qualitative assessments and complication rates were recorded.

    Main Results:

    • The flexible nephroscope facilitated the localization and removal of stone fragments atraumatically.
    • In 7 cases, intraoperative radiography failed to identify calculi that were subsequently located by nephroscopy.
    • All surgeons rated the flexible nephroscope as superior to rigid scopes, citing atraumatic insertion, superior optics, and visualization.

    Conclusions:

    • The flexible nephroscope provides significant advantages, including atraumatic insertion, enhanced visualization, and complete intrarenal inspection.
    • Its ability to allow total intrarenal inspection without trauma or bleeding makes it a valuable tool, recommended before forceps exploration.
