Pulsed solid-state thulium: YAG laser compared to holmium: YAG laser during mini-PCNL.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundHolmium: yttrium-aluminum-garnet (Ho: YAG) laser technology has long been employed for urinary stone fragmentation; however, its limitations have prompted the exploration of alternative systems such as thulium lasers. This study aims to compare a novel pulsed solid-state Thulium: YAG (Tm: YAG) laser to the standard Ho: YAG laser in Mini-percutaneous nephrolithotomy (Mini-PCNL) lithotripsy for renal calculi.
methodsIn total, 100 patients undergoing Mini-PCNL were enrolled in this clinical trial. Fifty patients treated with a holmium laser were selected from a retrospective database. These patients were compared to fifty patients who were prospectively enrolled and treated with a new thulium laser. Patient characteristics, stone parameters, operative details, and complications were recorded and analyzed statistically.
resultsBoth groups were comparable in demographics and stone characteristics. The Tm: YAG group demonstrated significantly shorter laser-on-time (7.20 vs. 10.46 min; p < 0.05) and operative time (32.6 vs. 41.2 min; p < 0.05) compared to the Ho: YAG group. There was no difference regarding stone-free rates (SFR) at 24 h, which were 90% in the Ho: YAG group and 92% in the Tm: YAG group (p > 0.999). Intraoperative complications did not significantly differ between groups.
conclusionThe novel pulsed solid-state Tm: YAG laser demonstrates advantages over the Ho: YAG laser in terms of laser-on-time and operation time, while showing comparable results for stone-free rate and complications. Further clinical trials are needed to compare Tm: YAG and Ho: YAG lasers in various contexts and to evaluate the Tm: YAG laser against the thulium fiber laser (TFL) for a comprehensive understanding of each technology's advantages.
