In 30 seconds

This randomized controlled trial evaluated the efficacy and safety of flexible ureteroscopy with a flexible and negative suction ureteral access sheath (FANS) compared to a traditional sheath in 185 patients with infectious upper urinary tract stones. The FANS group demonstrated significantly higher stone-free rates at both postoperative day 1 and 30 days, along with shorter operative times and hospital stays.

Key findings

  • The stone-free rate was significantly higher in the FANS group at both postoperative day 1 and 30 days.
  • Mean operative time was significantly shorter in the FANS group.
  • Quality of life improvement was greater in the FANS group.
  • The overall complication rate was significantly lower in the FANS group.

Why it matters

The findings suggest that using a flexible and negative suction ureteral access sheath may enhance stone clearance and reduce postoperative complications in patients with infectious upper urinary tract stones, potentially leading to better patient outcomes.
