Lasers and electricity are commonly used energy sources in urological surgery. They all have both advantages and disadvantages in tissue removal efficiency and hemostasis, and it is difficult for them to replace one another in clinical practice. This study aimed to develop a special surgical tool which can simultaneously transmit high-power laser energy and conduct electricity for urologic surgical procedures. Since this tool integrates the function of conducting laser and electrical energy through a laser fiber, we call it integrated fiber. As a product of this study, the integrated fiber can connect with a thulium laser and a bipolar plasma generator simultaneously. Using this fiber, an ex vivo simulation of transurethral vaporization of porcine kidney tissues was conducted. In terms of tissue removal efficiency, the laser-plasma and the plasma group showed the highest and the lowest, respectively. For thermal damage, there was no significant difference between the laser-plasma and laser group. Though a prototype, with this integrated fiber, the combined laser-plasma energy can vaporize kidney tissue more efficiently without additional thermal damage. This integrated dual-functional laser-electric optical fiber shows good application prospects in urological surgery.
激光和电是泌尿外科手术中常用的能量源。它们在组织切除效率和止血方面都有优缺点，在临床实践中很难相互替代。本研究旨在开发一种特殊的手术工具，该工具能够同时传输高功率激光能量并在泌尿外科手术过程中导电。由于该工具通过激光光纤集成了传导激光和电能的功能，我们将其称为集成光纤。作为本研究的产物，集成光纤可以同时与铥激光和双极等离子体发生器相连。使用这种光纤，对猪肾组织进行了经尿道汽化的体外模拟。在组织切除效率方面，激光-等离子体组和等离子体组分别表现出最高和最低效率。对于热损伤，激光-等离子体组和激光组之间没有显著差异。尽管是一个原型，但使用这种集成光纤，激光-等离子体组合能量可以更有效地汽化肾组织，而不会造成额外的热损伤。这种集成的双功能激光-电光纤在泌尿外科手术中显示出良好的应用前景。
