The Impact of Irrigation Fluid Temperature on Thulium Fiber Laser Stone Ablation: An In-Vitro Study "Presentation"
May 6, 2024
Andrei Cumpanas presented a study on the impact of irrigation fluid temperature on thulium fiber laser stone ablation, finding that while higher fluid temperatures were associated with increased ablation cone volume, the clinical significance was minimal compared to an increase in laser energy.

Andrei Cumpanas: Dear viewers, my name is Andrei Cumpanas. I'm a LIFT research scholar here at The University of California, Irvine's Department of Urology. Today, I'll be presenting the results of our study, the Impact of Irrigation Fluid Temperature on Thulium Fiber Laser Stone Ablation: An In-Vitro Study.
We sought to evaluate the impact of irrigation temperature on the amount of stone ablated during superpulse thulium fiber laser lithotripsy. 360 stones of different chemical compositions were immersed in normal saline at four different temperatures. With the tip of the laser fiber in contact with the surface of each stone, a single laser pulse with distinct energy settings was applied.
Optical Coherence Tomography was used to assess the volume of the resulting ablation cone. Except for uric acid stones, a higher fluid temperature was associated with a higher ablation cone volume at each of the three energy settings. However, a seven-degree Celsius increase in fluid temperature equated to only a 0.1 joule increase in laser energy. In conclusion, the impact of increased fluid temperature and stone ablation is of minimal clinical significance when compared to an increase in laser energy.
Thank you.
