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

Retrograde intrarenal surgery (RIRS) is a key technique for managing renal calculi. Despite advancements like the flexible and navigable suction ureteral access sheath (FANS-UAS), efficient stone fragment evacuation remains challenging due to limited irrigation flow and backflow-induced displacement. We report a novel technique using a ureteral catheter (UC) placed external to the FANS-UAS to generate directional, low-pressure saline irrigation during RIRS, aimed at enhancing stone evacuation and maintaining optimal intrarenal pressure (IRP). The integration of an external UC during RIRS is a simple, cost-effective modification that significantly enhances stone fragment evacuation and maintains safe IRP levels.
