Retrograde intrarenal surgery in the prone split-leg position for female upper urinary tract stones: a preliminary study of 16 cases.
Article in Frontiers in surgery, 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
Objectives: This study aims to preliminarily investigate the potential technical advantages of the prone split-leg position for treating upper urinary tract stones and evaluate its efficacy using computed tomography (CT). Materials and methods: A retrospective analysis was conducted on the clinical data of 16 female patients who underwent retrograde intrarenal surgery (fURS) for upper urinary tract stones in the prone split-leg position at our hospital between July and September 2024. All patients were treated using flexible ureteroscopes and received CT scans before and after the operation to assess surgical outcomes. Results: All surgeries were successfully performed in the prone split-leg position, with an average operation time of 62.25 ± 25.92 min. The immediate stone clearance rate was 100%, and no complications were observed. Conclusion: Retrograde intrarenal surgery in the prone split-leg position is an effective treatment for upper urinary tract stones in female patients. This position facilitates ureteroscopic access to the renal pelvis and the insertion of ureteral guide sheaths, improves the immediate stone clearance rate, reduces intrarenal pressure, and represents an efficient, economical, and safe treatment method.
