    Area of Science:

    • Nephrology
    • Surgical Imaging
    • Medical Device Technology

    Background:

    • Intraoperative visualization of renal calculi fragments can be challenging.
    • Accurate localization of intraparenchymal calculi is crucial for effective surgical removal.

    Purpose of the Study:

    • To introduce and evaluate a miniature vacuum cassette for intraoperative visualization of intraparenchymal calculi fragments.
    • To describe a low-dose radiographic technique optimized for this cassette.

    Main Methods:

    • Development of a kidney-contoured miniature vacuum cassette designed for reusable sterilization.
    • Implementation of a low-dose imaging protocol utilizing single-emulsion film and high-definition intensifying screens.
    • Utilization of a vacuum system to ensure optimal screen-film contact for enhanced image quality.

    Main Results:

    • Successful intraoperative visualization of intraparenchymal calculi fragments using the vacuum cassette.
    • The developed low-dose technique provides clear imaging of calculi fragments.
    • The vacuum cassette system ensures good screen-film contact, crucial for diagnostic accuracy.

    Conclusions:

    • The miniature vacuum cassette is a viable and effective tool for intraoperative visualization of renal calculi fragments.
    • The associated low-dose imaging technique offers a safe and efficient method for stone fragment detection.
    • The reusability and sterilizability of the cassette contribute to its practical application in surgical settings.
