Objective:

To compare the perioperative clinical data of patients with upper urinary tract infective stones treated with flexible ureteroscopic lithotripsy (FURL) alone versus FURL combined with a flexible navigable suction ureteral access sheath (FANS-UAS), highlighting the clinical significance of this comparison.

Key Findings:
  • FURL combined with FANS-UAS showed improved stone clearance rates compared to FURL alone, suggesting enhanced efficacy in treatment.
  • The use of FANS-UAS reduced intrarenal pelvic pressure during the procedure, which may lead to better patient outcomes.
  • Patients treated with FANS-UAS experienced fewer complications related to stone removal, indicating a safer approach.
Interpretation:

The combination of FURL with FANS-UAS may enhance the effectiveness and safety of treating infected upper urinary tract stones, potentially leading to better patient outcomes and influencing clinical practice.

Limitations:
  • The study is retrospective and may be subject to selection bias, particularly in patient group allocation.
  • The sample size is relatively small, which may limit the generalizability of the findings and the robustness of conclusions drawn.
Conclusion:

FURL combined with FANS-UAS represents a promising approach for managing infected upper urinary tract stones, warranting further prospective studies to validate these findings and explore specific areas for future research.
