    New fiberoptic scopes, initially for biliary procedures, proved effective for removing kidney stones and examining the renal pelvis and ureter. These reliable instruments facilitated easy manipulation, paving the way for improved endoscopic nephroscopy.

    Area of Science:

    • Urology
    • Minimally Invasive Surgery
    • Endoscopy

    Background:

    • Novel fiberoptic scopes, developed for biliary tract operations, were evaluated for renal pelvis and ureter applications.
    • The study assessed the utility of two scope models: CHF-X1 (6.6 mm) and CHF-X2 (4.5 mm).

    Observation:

    • The scopes were utilized in 23 cases for pyelolithotomy stone removal and renal pelvic/ureteral examinations.
    • Simultaneous irrigation and forceps manipulation were possible with the CHF-X1 model.
    • The CHF-X2 model allowed for irrigation only.

    Findings:

    • The fiberoptic scopes demonstrated reliability in clinical use.
    • Easy endoscopic forceps manipulation was achieved with the evaluated instruments.
    • The CHF-X1 scope offered greater functional versatility due to simultaneous irrigation and manipulation capabilities.
