To sheath or not to sheath in flexible ureteroscopy: A randomized controlled trial.
Article in Arab journal of urology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: To assess the effect of employing UAS compared to not using UAS in FURS concerning stone-free rate, operative duration, and intraoperative and postoperative complications. Methods: A total of 120 patients presenting with symptomatic upper ureteric and renal stones were recruited and allocated into two equal groups. Group A underwent flexible ureteroscopy (FURS) without using ureteral access sheaths (UAS), while Group B underwent FURS with UAS. Results: There were no statistically significant differences among the groups for the Stone-free rate, operative duration, length of hospital stay, and postoperative pain, with p-values of 0.543, 0.122, 0.639, and 0.083, respectively. However, group A experienced a significantly higher occurrence of postoperative complications, affecting 14 patients (23.3%), compared to five patients (8.3%) in group B, with a p-value of less than 0.05. These complications mainly presented as postoperative fever and urosepsis. Conclusion: Utilizing UAS alongside Flexible ureteroscopy had no impact on stone-free rate, operative time, hospital stay, or intraoperative complications. However, it notably lowered postoperative infective complications.
