    Area of Science:

    • Urology
    • Minimally Invasive Surgery

    Background:

    • Ureteral stones and misplaced double J-stent catheters present diagnostic and therapeutic challenges.
    • Ureterorenoscopy offers a minimally invasive approach for managing ureteral foreign bodies and calculi.

    Purpose of the Study:

    • To evaluate the efficacy and safety of ureterorenoscopy for removing ureteral stones and foreign substances.
    • To assess the utility of ureterorenoscopy in managing specific ureteral conditions.

    Main Methods:

    • Retrospective analysis of 14 cases involving ureteral stones (n=13) and a foreign substance (n=1).
    • Procedures performed under spinal or epidural anesthesia using a ureterorenoscope, retrograde pyelogram, and stone retrieval devices.
    • Visualization and removal of calculi or foreign bodies via the ureterorenoscope's working channel.

    Main Results:

    • Successful removal of the foreign substance and 77% of ureteral stones.
    • Ureterorenoscopy demonstrated its usefulness in managing these ureteral conditions.
    • A 14% complication rate was observed, including ureteral penetration and injury during biopsy.

    Conclusions:

    • Ureterorenoscopy is a valuable tool for ureteral stone and foreign body removal.
    • Careful manipulation of the ureterorenoscope is essential to minimize the risk of ureteral injury.
    • Further refinement in technique may improve safety outcomes.
