The novel Quanta Litho 150 W (Samarate, Italy) was recently introduced and incorporates new pulsed modulation settings. We sought to analyze ablation rate and efficiency in short pulse (SP), virtual basket (VB), and vapor tunnel (VT) pulsed modulations, in an pop-dusting simulation across different settings at a fixed power of 30 Watts (W) and fixed periods of time.
Seven millimeter BegoStone phantoms were subjected to lithotripsy in a simulated calyx using Holmium: yttrium:aluminum garnet Quanta System 150 W. 30 W was applied at different settings across three pulse modulation modes: SP, VB, and VT. Ablation rate and efficiency were and compared between the three groups.
Maximum ablation efficiency for the VB and VT groups was achieved at VB 2J x 15 Hz and VT at 2.5 J x 12 Hz. Ablation efficiency decreased with higher Joules. VB at 1.5 J x 20 Hz and SP at 2.5 J x 12 Hz were the only settings to obtain 85% ablation at 5 min.
laser lithotripsy using a BegoStone phantom, VB at 2J x15 Hz and VT at 2.5 J x 12 Hz were the most efficient setting for pop-dusting with the Quanta Litho 150. The highest efficiency (mg/min) was achieved with VB at 2 J x 15 Hz and VT at 2.5 J x 12 Hz at 1:15 min.
新型Quanta Litho 150 W（意大利萨马雷）最近推出，采用了新的脉冲调制设置。我们试图在固定功率30瓦（W）和固定时间段内，分析不同设置下短脉冲（SP）、虚拟篮筐（VB）和蒸汽隧道（VT）脉冲调制的消融率和效率。
使用钬：钇：铝石榴石Quanta系统150 W对7毫米的BegoStone模型进行模拟肾盏碎石术。在三种脉冲调制模式（SP、VB和VT）的不同设置下施加30 W功率。比较三组之间的消融率和效率。
VB组和VT组在VB 2J×15 Hz和VT 2.5 J×12 Hz时达到最大消融效率。消融效率随焦耳数增加而降低。1.5 J×20 Hz的VB和2.5 J×12 Hz的SP是仅有的在5分钟时实现85%消融的设置。
使用BegoStone模型进行激光碎石术时，VB 2J×15 Hz和VT 2.5 J×12 Hz是Quanta Litho 150进行碎末清除最有效的设置。在1:15分钟时，2 J×15 Hz的VB和2.5 J×12 Hz的VT实现了最高效率（毫克/分钟）。
