    Area of Science:

    • Urology
    • Surgical Instrumentation

    Background:

    • Traditional nephroscopes lack tactile sensation, hindering precise stone removal.
    • A need exists for advanced endoscopic tools in minimally invasive urological surgery.

    Observation:

    • A new 2.3 mm diameter operative nephroscope combines fiberoptic visualization with tactile feedback.
    • The instrument features a 70-degree visual field and a 600 mm working length.
    • It integrates with hollow-arm forceps for irrigation and instrument passage.

    Findings:

    • The nephroscope facilitated pyelolithotomy in 26 patients with multiple renal stones.
    • Successful stone removal was achieved in all but one patient.
    • The device was also used to examine renal pelves in 16 patients.
