Summary
This study provides initial recommendations for using Holmium:YAG (Ho:YAG) and Thulium Fiber Laser (TFL) in endocorporeal lithotripsy. Laser settings for stone management should be adapted based on treatment goals and stone characteristics.
Area of Science:
- Urology
- Laser technology
- Medical device development
Background:
- Endocorporeal lithotripsy has advanced with laser technology.
- Holmium:YAG (Ho:YAG) and Thulium Fiber Laser (TFL) are the primary laser sources.
- Standard laser settings include dusting, fragmentation, and "pop-corning".
Purpose of the Study:
- To establish the first recommendations for laser use in stone management.
- To provide guidance on optimal laser settings for different scenarios.
- To adapt European Association of Urology (EAU) guidelines to the French context.
Main Methods:
- Development of recommendations using the Clinical Practice Recommendation (CPR) method.
- Adaptation of existing guidelines using the ADAPTE method.
- Consideration of EAU urolithiasis guidelines (2022).
Main Results:
- The recommendations cover laser settings for stone management.
- Settings require modulation based on treatment effects, stone location, and type.
- The guidelines are adaptable to specific clinical contexts.
Conclusions:
- These recommendations offer initial guidance on laser settings for endocorporeal lithotripsy.
- Flexible adjustment of laser parameters is crucial for effective stone treatment.
- The developed guidelines support evidence-based practice in urolithiasis management.
