Comparison of flexible vacuum-assisted ureteral access sheath versus conventional sheath combined with single-use flexible ureteroscope in the treatment of renal calculi.

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
To evaluate the safety and efficacy of the flexible vacuum-assisted ureteral access sheath combined with the single-use flexible ureteroscopy in the treatment of renal calculi. We prospectively analyzed the patients treated with single-use flexible ureteroscopy from January 2023 to December 2023, among which 113 cases were treated with flexible vacuum-assisted ureteral access sheath (FV-UAS group) and 113 cases were treated with conventional sheath (conventional sheath group). Patient data ofthe two groups were collected and recorded before and after operation. No significant differences were observed between the two groups regarding demographics and pre-operative clinical characteristics. The duration of the operation was significantly longer in the FV-UAS group (79.5 ± 6.8 min) compared to the conventional UAS group (65.2 ± 7.3 min). However, the stone free rate (SFR) at one day and one month post-operation in the FV-UAS group was 85.6% and 98.2%, respectively, significantly higher than that in the conventional UAS group (72.6%, 90.3%). Complications such as infection and urosepsis were more common in conventional UAS group. Notably, hospitalization costs were lower in the FV-UAS group. Flexible vacuum-assisted ureteral access sheath combined with flexible single-use ureteroscope is a feasible and effective method for treating renal calculi. It offers higher SFR and lower rate of infectious complications.
