Feasibility of flexible and navigable suction ureteral access sheath in pediatric ureteroscopy: A systematic review from the European Association of Urology Section of Endourology.
Review in Asian journal of urology, 2026. 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: The introduction of a flexible and navigable suction ureteral access sheath (FANS-UAS) has further enhanced retrograde intrarenal surgery (RIRS) by improving kidney stone clearance and reducing operative challenges. However, evidence for its use in the pediatric population remains sparse. Thus, this systematic review focuses on the current evidence on the use of a FANS-UAS during RIRS in children with renal stones. Methods: A systematic search of PubMed, Cochrane Library, and Google Scholar was conducted in May 2025 following the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines and PROSPERO registration (CRD420251049140). Studies were included if they reported original data on the use of a suction ureteral access sheath (UAS) during RIRS in pediatric patients (<18 years). Data on patient demographics, stone characteristics, surgical outcomes, and complications were extracted and analyzed descriptively. Results: Out of 49 screened studies, three met the inclusion criteria, including 74 pediatric patients. A FANS-UAS was used in all cases, with 97% utilizing 10/12 Fr UAS and 91% employing a 7.5 Fr flexible ureteroscope. The pooled stone-free rate was 99%, with complications limited to minor ureteral injury (4.1%) and Clavien-Dindo Grade I/II events (9.5%). One study showed the superiority of a FANS-UAS over a conventional UAS in operative time and initial stone-free rate. However, the evidence was limited by small sample sizes and heterogeneity. Conclusion: RIRS with a FANS-UAS a is a safe and effective option for managing pediatric urolithiasis, including large and multiple stones. Nevertheless, current evidence is based on a small number of studies with limited generalizability. Further prospective research is needed to validate these findings, to explore the role of suction, and to investigate various UAS and endoscope configurations.
