Dusting and pop-dusting for kidney stone disease: Video and outcomes

摘要

Ureteroscopy and laser stone fragmentation (URSL) can now be performed using the “dusting and pop-dusting” method. The method comprises a two-stage combined treatment using the long-pulse Ho:YAG laser: initially in contact with the stone (“dusting”) with energy setting 0.2–0.5 J and frequency 40–50 Hz, followed by the non-contact mode (“pop-dusting”; 0.5–0.7 J/20–40 Hz). Herein, we intend to examine the outcomes of this method for renal and ureteric stones using a 100-W holmium laser.
