New flexible ureteroscopes enable wireless, no-touch upper urinary tract procedures. This safe and feasible technique improves access and outcomes for stone treatment and other interventions.

Area of Science:

  • Urology
  • Endourology
  • Minimally Invasive Surgery

Background:

  • Advancements in flexible ureteroscopes enhance diagnostic and therapeutic capabilities.
  • New instruments allow greater access to the upper urinary tract.
  • Facilitation of wireless ureteroscopy is a key innovation.

Purpose of the Study:

  • To evaluate the efficacy and safety of a new generation of flexible ureteroscopes.
  • To assess the feasibility of wireless, no-touch ureteroscopy.
  • To compare outcomes with previous flexible ureteroscopy techniques.

Main Methods:

  • Prospective data collection for 460 consecutive upper urinary-tract procedures using a 7.5F flexible ureteroscope.
  • Evaluation of indications, access techniques, complications, and stone treatment success rates.

  • Comparison of clinical data with a historical cohort of 1000 flexible ureteroscopies.

    • Main Results:

    • Ureteral dilation was unnecessary in 89% of procedures (352/460).
    • Wireless ureteroscopy (no guidewire needed) was achieved in 227 procedures.
    • Stents were in place or recently removed in 24% of cases.

    Conclusions:

    • Wireless, no-touch flexible ureteroscopy is a safe and feasible technique for upper urinary tract procedures.
    • New flexible ureteroscopes offer improved access and control, leading to better outcomes.
    • This technology represents a new era in endoscopic treatment of the upper urinary tract.
