Implication

Randomized trial compares stone-free rates in thulium fiber laser and holmium:YAG lithotripsy for kidney stones, suggesting thulium fiber laser as a preferred option.

Key Points

To compare the effectiveness and safety of thulium fiber laser with low-power holmium:YAG laser lithotripsy for kidney stones.
Single-center randomized controlled trial
Enrolled 231 patients with renal/proximal ureteral stones (10–20 mm)
Patients randomized 1:1 to thulium fiber laser or holmium:YAG lithotripsy with outcome assessors blinded.
Total stone-free rate significantly higher with TFL (94.4%) compared to Ho:YAG (86.0%), p = 0.048 (NNT = 12).
Dusting efficiency comparable between groups (1.78 vs 1.82 sec/mm3, p = 0.571).
Similar complication rates with TFL (6.6%) and Ho:YAG (4.6%), p = 0.496.
