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

purposeThis study aimed to evaluate the feasibility, outcomes, and intraoperative strategies of endoscopic management for de novo kidney allograft stones, focusing on decision-making and safety considerations unique to the transplant recipients.

methodsWe retrospectively reviewed six kidney transplant recipients who underwent endoscopic treatment for de novo kidney allograft stones between June 2018 and October 2024. Surgical approaches, intraoperative modifications, and perioperative outcomes were analyzed based on operative records and imaging studies.

resultsRetrograde ureteroscopy (URS) was successfully completed in three patients, whereas two required antegrade URS and one required intraoperative conversion from a retrograde to a percutaneous approach due to difficult ureteral access. The median operative time was 119 min. All patients achieved a stone-free status, confirmed by postoperative computed tomography, with no deterioration in graft function or major complications. No infectious or hemorrhagic events were observed.

conclusionEndoscopic lithotripsy is a feasible and safe treatment for de novo kidney allograft stones when surgical planning accounts for graft anatomy and intraoperative flexibility. A tailored approach allowing switching between retrograde and percutaneous access is essential for ensuring procedural safety and preserving graft function. Although the small sample size limits generalizability, the findings provide practical insights for optimizing graft-preserving kidney stone surgery.
