Summary

Flexible mini-ureteroscopes offer an effective diagnostic and therapeutic approach for upper urinary tract diseases like stones and tumors. While successful in 78% of cases, instrument fragility remains a key limitation.

Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Endourology

Context:

  • Upper urinary tract diseases require effective diagnostic and therapeutic interventions.
  • Flexible ureteroscopy has emerged as a key technique for managing these conditions.
  • Active deflection flexible mini-ureteroscopes represent an advancement in endoscopic capabilities.

Purpose:

  • To evaluate the efficacy and safety of active deflection flexible mini-ureteroscopes.
  • To assess their application in diagnosing and treating upper urinary tract pathologies.
  • To identify the limitations and potential improvements for these instruments.

Summary:

  • A series of 137 flexible ureteroscopies were performed on 111 patients for upper tract stones (66%) and urothelial tumors (25%).

  • The procedures achieved a 78% success rate with a mean operating time of 42 minutes and a 2-day hospital stay.
  • Complications occurred in 8% of cases, with instrument fragility noted as a significant limitation.

    • Impact:

    • Flexible mini-ureteroscopy is a reproducible and minimally traumatic technique for lesions above the iliac vessels.
    • The integration of tools like Holmium:Yag laser enhances endoscopic treatment possibilities.
    • Addressing instrument fragility is crucial for broader adoption and improved patient outcomes.
