Pediatric retrograde intrarenal surgery: does age matter?
Article in Pediatric surgery international, 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
objectiveThe aim of this study was to evaluate the outcomes of retrograde intrarenal surgery (RIRS) in the pediatric population and to investigate the factors affecting surgical success. MATERIALS AND
methodsThe medical records of pediatric patients who underwent RIRS at Hacettepe University Hospital between 2014 and 2023 were retrospectively reviewed. Patient age, stone number, stone size, stone location, stone density measured in Hounsfield units (HU), presence of hydronephrosis, preoperative and postoperative double-J stent (DJS) placement, and use of a ureteral access sheath (UAS) were analyzed in relation to stone-free rates at 6 weeks and final stone-free outcomes.
resultsA total of 59 patients (62 renal units) who underwent 64 surgical procedures were included in the study. The mean age of the cohort was 7.48 ± 5.5 years. High-grade hydronephrosis was present in 40.6% of patients, and multiple stones were detected in 33.9% preoperatively. Residual stones were observed in 43.7% of patients in the early postoperative period, while the final stone-free rate was 64.1%. A trend toward a higher residual stone rate was observed in patients with stone density ≥ 700 HU (p = 0.10). Although the use of a ureteral access sheath appeared to reduce the need for additional intraoperative procedures, it did not significantly improve stone-free rates (p = 1.00). Ureteral access sheath placement was significantly more common in patients aged ≥ 5 years (p = 0.021). Postoperative febrile urinary tract infection occurred more frequently in patients younger than 5 years of age (p = 0.025).
conclusionRIRS is a feasible and effective treatment option for pediatric urolithiasis, providing acceptable stone-free rates with low complication rates. However, special attention should be paid to postoperative febrile urinary tract infections, particularly in patients younger than 5 years.
