概括

最佳的纤维激光 (TFL) 石解术设置涉及高脉冲能量和低频率,例如0.8 J/12 Hz. 这种方法提高了结石切除效率,减少了手术时间,同时最大限度地降低了结石治疗的热损伤风险.

科学领域:

泌尿器科泌尿器科泌尿器科泌尿器科
激光光电三症是什么意思
腎石病的治療方法

背景情况:

硫纤维激光 (TFL) 石灰管是结石管理的一个关键模式.
优化TFL设置对于平衡治疗疗效和安全至关重要.
了解脉冲能量和频率对石头剥离和热效应的影响至关重要.

研究的目的:

为了确定最佳的纤维激光 (TFL) 石灰管术设置,以获得最大的治疗效率.
为了确定设置,以尽量减少热伤害风险在石灰管化期间.
为了缩短结石切除的整体手术时间.

主要方法:

实验室脏模型被用来模拟TFL在上方玻璃杯中的石.
使用BegoStone幻石和氧化单水化合物 (COM) 石头来测试各种脉冲能量 (E_P) 和频率 (F) 组合.
使用嵌入式热电偶监测温度变化和热伤害风险.

主要成果:

高脉冲能量/低频 (E_P/低F) 设置显示出高于低E_P/高F的治疗效率.
最佳设置为0.8 J/12 Hz显著提高了处理效率,并将残留碎片减少了35%,程序时间减少了36%.
在高E_P/低F组合的10W功率设置下,热伤害风险仍然低于安全值.

结论:

高E_P/低F设置,特别是0.8J/12Hz,对于COM石的TFL石术是最佳的.
这些设置提高了处理效率,减少了残留碎片,同时保持了热安全.
需要进行进一步的研究,以确定不同成分的结石的最佳TFL设置.

Urinary Tract Calculi VI: Surgical Management

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...
