    Area of Science:

    • Urology
    • Minimally Invasive Surgery

    Background:

    • Traditional surgical removal of renal calculi involves large, traumatic incisions.
    • There is a need for less invasive methods to treat kidney stones.

    Purpose of the Study:

    • To evaluate a novel, less traumatic method for removing calculi from the renal collecting system.
    • To assess the feasibility and success rate of this new procedure.

    Main Methods:

    • A minimally invasive approach using a nephrostomy tube, guide wire, and dilators to access the renal pelvis.
    • Introduction of a cystoscope and stone basket through the established track for stone retrieval.
    • Procedure attempted in 31 patients.

    Main Results:

    • The procedure was successful in 20 out of 31 patients (64.5%).

    Related Experiment Videos

  • Failure in 11 patients was due to initial needle placement issues (5) or inability to retrieve the stone (6).
  • The method is significantly less traumatic than conventional surgery.

    • Conclusions:

    • This new technique offers a less traumatic alternative for renal calculi removal.
    • Further development with flexible nephroscopes and ultrasonic lithotripsy could expand its applicability to larger or peripherally located stones.
