Summary
Thulium fiber laser (TFL) lithotripsy during retrograde intrarenal surgery (RIRS) is safe and effective for ureteral and renal stones. This study evaluated TFL efficacy, safety, and settings, showing minimal complications.
Area of Science:
- Urology
- Endourology
- Laser Surgery
Background:
- Kidney and ureteral stones are common urological conditions.
- Retrograde intrarenal surgery (RIRS) is a minimally invasive treatment option.
- Laser lithotripsy is a key component of RIRS.
Purpose of the Study:
- To assess the efficacy and safety of thulium fiber laser (TFL) for lithotripsy during RIRS.
- To analyze optimal laser settings for TFL in treating ureteral and renal stones.
- To report complication rates associated with TFL lithotripsy.
Main Methods:
- Prospective study of 50 patients undergoing RIRS with TFL.
- Utilized 200 µm fibers for ureteral stones and 150 µm for renal stones.
- Recorded stone characteristics, laser settings, ablation speed, and power.
Main Results:
- Evaluated 50 patients with ureteral and renal stones.
- Analyzed stone size, density, laser-on time, and energy parameters.
- Observed low overall complication rates in both stone groups.
Conclusions:
- Thulium fiber laser (TFL) demonstrates safety and efficacy in lithotripsy during RIRS.
- TFL is a viable option for managing ureteral and renal stones with minimal complications.
