Ureteral stent biomaterial encrustation after endoscopic lithotripsy: a randomized, single-blind study.
Trial report in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
This study evaluated the adherence of bacteria, calcium, and magnesium to three different ureteral stents after endoscopic surgery for urinary calculi. We randomly assigned 61 patients requiring the insertion of ureteral stents after urinary calculi treatment into three groups: Percuflex with a coating composition of Hydroplus (n = 21); Tria with a coating composition of Percushied (n = 22); and InLay Optima, which had a proprietary pHreeCoat coating (n = 18). All stents were removed and evaluated 1 month after treatment. The primary outcome was biomineral attachment to the ureteral stent. Calcium and magnesium contents were measured using atomic absorption spectrometry after the stent had been vortexed in a solution of saline and hydrochloric acid at pH 2. Bacteria were measured through flow cytometry of the washing solution collected by decantation after stent fragments had been immersed and vortexed in a saline solution. Median amounts of calcium and magnesium adhered to Percuflex were significantly higher than those adhered to Tria and InLay Optima. The median number of bacteria adhered was also highest in Percuflex compared to that in the other two groups, although without a statistically significant difference. These findings suggest that selecting stents with superior coating materials enhances patient outcomes and reduces stent-related complications.
