Is flexible and navigable suction ureteral access sheath (FANS-UAS) the next best development for retrograde intrarenal surgery in children? Results of a prospective multicentre study.
Article in World journal of urology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 20 papers, 3 of them syntheses that pooled 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.
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
purposeTo assess retrograde intrarenal surgery (RIRS) outcomes in children using ClearPetra, a flexible and navigable suction ureteral access sheath (FANS-UAS).
methodsChildren with kidney stone(s) only undergoing RIRS in 8 centers were prospectively included (September 2023-May 2024). EXCLUSION CRITERIA: ureteral stone, bilateral procedures, anomalous kidneys, surgery for residual fragments. Lithotripsy was performed using either a Holmium or Thulium fiber laser. Postoperative pain was assessed within 24 h using a 10-point visual analogue score. The use of FANS-UAS was graded by surgeons after each case using a 5-point likert scale. Low-dose non-contrast CT scan was performed before and within 30 days of RIRS to assess residual fragments (RFs). Stone-free status was defined as no RF or single RF up to 2 mm.
results50 children were included. 66% were male. Mean age was 6.6 (± 3.38) years. 88% stones were < 2 cm. one-third of the patients had a stone volume > 1500mm
conclusionsOur study shows that the use of FANS-UAS in paediatric RIRS is feasible and safe with a low rate of complications and excellent stone-free rate.
