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

purposeTo evaluate the safety and clinical performance of a fluid-management system with intrarenal pressure management during flexible ureteroscopy in patients with renal or ureteral stones.

methodsprospective, observational, descriptive study at two centers in Santiago, Chile, from April to June 2025. Adults (≥ 18 years) with confirmed upper urinary tract stones undergoing flexible ureteroscopy were included (n = 14). Exclusion criteria comprised active urinary infection, significant anatomical abnormalities, pregnancy or lactation. All procedures employed a single-use LithoVue Elite ureteroscope integrated with Asurys. Continuous intrarenal pressure measurements were recorded, with the Asurys system configured in LithoVue Elite Mode using a target pressure limit of 25-35 cmH₂O (18.4-25.8 mmHg) (flow limiter) and adjustable flush limiter (typically 80-100 cmH₂O (58.8-73.6 mmHg)). Intraoperative parameters, including operative time, laser usage, and instrument sheath utilization, were documented. Postoperative complications were classified by Clavien-Dindo. Laboratory values (e.g., C-reactive protein, fibrinogen, creatinine) were obtained preoperatively and 2-3 h postoperatively.

resultsThe mean age was 51 years, 78% were male. Stones had a median diameter of 8 mm and a median volume of 189.9 mm³. Median operative time was 60 min (range 50.0-90.5). The mean intrarenal pressure was 29 ± 13 cmH₂O (21.3 ± 9.6 mmHg). One patient (7%) experienced a Clavien-Dindo II urinary tract infection; one (7%) had grade I pain.

conclusionAsurys was associated with low complication rates and high surgeon satisfaction, suggesting that automated pressure control is safe and effective during flexible ureteroscopy.
