1 · What the graph read from it

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.

2 · The registry

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

backgroundUrinary tract calculi are highly prevalent worldwide. Vacuum-Assisted Dedusting Lithotripsy (VADL) integrates a Flexible and Navigable suction ureteral access Sheath (FANS) with active suction to overcome limitations of traditional methods.

methodsThis retrospective cohort study analyzed 1267 patients with renal/proximal ureteral calculi (stratified by stone size: ≤ 2 cm, 2-3 cm, > 3 cm) treated with VADL (2022-2024). Primary outcomes were stone-free rate (SFR) and complications.

resultsOverall 3-month SFR was 79.34% (941/1186), highest in ≤ 2 cm group (85.96%, OR = 3.2, 95%CI 2.1-4.8). Clavien-Dindo ≥ III complications occurred in 0.34%. Ureteral injury (≥ Grade 2) was 9.61%, associated with sheath size (12/14F: 15.53% vs. 10/12F: 6.63%, P = 0.01).

conclusionsVADL achieves high SFR with minimal severe complications, particularly for stones ≤ 2 cm.
