Abstract :

Management of large renal stones remains challenging despite advances in endourology. This prospective study compared holmium:YAG and thulium fiber lasers (TFL) in stone fragmentation efficiency, operative time, and complications during flexible ureteroscopy. Sixty patients with renal calculi >2 cm were randomized to holmium or TFL lithotripsy. Stone free rates (SFR), operative parameters, and postoperative outcomes were recorded. TFL demonstrated significantly faster stone ablation rates and shorter operative times (mean 45 vs. 60 minutes, p < 0.01) with comparable SFR (~85%). Complication rates were low and similar between groups. The results suggest TFL may offer advantages in efficiency without compromising safety for large renal stones.
