    Infected upper urinary tract stones account for approximately 15% of urinary tract stones and are associated with severe complications.

  • 2

    Flexible ureteroscopic lithotripsy (FURL) has emerged as a competitive alternative to percutaneous nephrolithotripsy for treating infected stones.

  • 3

    The study analyzed data from 91 patients treated for infected stones, comparing outcomes between FURL and FURL combined with FANS-UAS.

  • 4

    FANS-UAS enhances the efficacy of lithotripsy by facilitating the extraction of stone fragments in a powdered state.

  • 5

    The study aims to optimize surgical strategies for managing infected stones in the upper urinary tract through comparative analysis.
