In 2017, Lumenis introduced Moses™ Technology which uses modulation enhance the delivery energy from fiber stone minimize retropulsion. Since introduction Technology, other companies brought additional concepts market. The purpose in vitro study compare characteristics efficiency Lumenis' with Quanta’s Vapor Tunnel™. METHODS: Submerged BegoStone phantoms were systematically ablated using either MOSES™Pulse 120H or Quanta Litho 100 clinical system. Two energies (0.4 J 1 J), three fiber-stone standoff distances (0.5, 1, 2 mm), all available modes for each tested combination. speed was adjusted scan across surface at pulse/mm 10 pulses/mm form single craters an trough, respectively. Volumes mm trough segments imaged quantified optical coherence tomography. RESULTS: Ablation volumes increased higher shorter distance. Among modes, Moses Distance superior 0.5 testing testing. Tunnel crater demonstrated similar depth distances. Long Pulse only modality 0.4 had volume mm. modulated pulses performed similarly CONCLUSIONS: benchtop model lithotripsy, significantly impacted type. non-inferior parameters. maintained its efficacy best distance increased.
