Comparison of dusting and fragmentation techniques using an aspiration access sheath: an in vitro study.

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
purposeSuction during flexible ureteroscopy improves stone clearance and lowers complications. The aim of this study is to provide one of the first in vitro comparisons of dusting and fragmentation techniques during laser lithotripsy using an aspiration access sheath.
methodsThe bench model consisted of a modified 50-cc syringe that served as a calyx model, into which an 11-13 Fr suction access sheath and artificial BegoStone stones were placed. Three trials were performed by 3 surgeons using Thulium Fiber Laser (TFL) for lithotripsy, using both dusting and fragmentation settings and techniques. The primary outcomes were evaluation of energy usage, particle size distribution, procedural efficiency and scope entry-exit count.
resultsFragmentation showed shorter lasing times (31.15 vs 45.15 min, p < 0.001) and greater ablation efficacy (29.64 vs 24.55 mm
conclusionFragmentation using an aspiration sheath shortens the lasing time and improves ablation efficacy, but it also increases the frequency of scope entries and may result in endoscope damage. Dusting produces a finer particle dispersion despite using more energy. The choice of technique should be tailored to the demands of the patient and the surgeon.
