| Popis: | Introduction and Objectives: Ureteroscopy is the gold standard for most urinary tract calculi. Our institute recently incorporated a powerful 120 W holmium laser machine integrating innovative technology (Lumenis® MOSES PulseTM120H Holmium:YAG laser; Lumenis Ltd.). In this retrospective comparative study, we evaluated the influence of stone density on laser dusting time in a high-power 120 W laser machine vs a standard 20 W machine (Dornier Medilas® H20 Holmium:YAG laser; Dornier Ltd.) Methods: We conducted a retrospective review of medical records of patients who underwent ureteroscopy during the years 2013-2018 for a solitary stone. Stone and clinical characteristics, among other parameters, have been evaluated, including the total laser time until complete stone dusting. Results: Among 631 eligible patients, 462 were treated with a 20 W standard laser and 169 patients with a p120w laser machine. Overall laser time was less than half with p120w laser vs d20w (195 seconds vs 397.14 seconds, p-value |
