Efficacy and safety of two tip flexible suctioning ureteral access sheaths combined with a 7.5Fr flexible ureteroscope: a retrospective 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
Objective: This study aimed to compare the efficacy and safety of two tip-flexible suctioning ureteral access sheaths (TFS-UAS), 12/14Fr (Group A) and 10/12Fr (Group B), combined with a 7.5Fr flexible ureteroscope (f-URS) for treating upper ureteral and renal stones. Methods: A retrospective analysis of 168 patients undergoing retrograde intrarenal surgery (RIRS) was conducted. Group A ( Results: Baseline characteristics were comparable between groups. Group A demonstrated significantly shorter operation (72.5 vs. 78.5 min, Conclusion: The 12/14Fr TFS-UAS combined with a 7.5Fr f-URS offers superior lithotripsy efficiency and immediate SFR compared to the 10/12Fr variant, while maintaining comparable long-term outcomes and safety. These findings support its clinical preference for RIRS in upper tract calculi.
