    The small fragment removal system (SFRS) aims to improve stone extraction during lithotripsy by eliminating small fragments immediately post-fragmentation.

  • 2

    A clinical trial evaluated the safety and efficacy of the SFRS, focusing on intra-renal pressure and the proportion of stone fragments extracted.

  • 3

    The SFRS consists of a Syphon Ureteric Access Sheath, a Dual Action Pump, and an Agitator to enhance fragment removal during procedures.

  • 4

    Initial findings suggest that the SFRS could eliminate over 75% of stone pieces, addressing the issue of residual fragments after lithotripsy.

  • 5

    The trial received ethical approval and included patients requiring flexible ureteroscopy and laser lithotripsy for renal stones.
