Enhanced Pressure Management Using an Upgraded Vacuum-Assisted Ureteroscopic System: Experimental Validation and Predictive Modeling.
Article in Urologia internationalis, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionThe aim of this study was to evaluate the pressure-control performance and irrigation efficiency of an upgraded vacuum-assisted ureteroscopic system (VA-URS) compared with traditional ureteroscopy (T-URS) using an in vitro kidney model.
methodsAn artificial renal pelvis model was used to simulate ureteroscopy under varying irrigation pressures (50, 100, 150 cmH
resultsVA-URS consistently produced lower intrapelvic pressures than T-URS across all settings. At 50 cmH
conclusionsThe upgraded VA-URS system significantly enhances intrapelvic pressure management and irrigation efficiency compared with T-URS in this in vitro model. These bench findings support further translational evaluation; however, animal and clinical studies are required to confirm clinical benefit and safety.
