Outcomes and complications of different approaches for 1-2 cm upper tract stones in the paediatric population: bicentric retrospective analysis.
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
purposeTo evaluate outcomes and complications of different surgical approaches for 10–20 mm internal stones in children, based on bicentric real-world experience. MATERIALS AND
methodsWe retrospectively analysed 96 patients treated between 2009 and 2022 at two tertiary referral centres. Data included demographics, stone characteristics, treatment (extracorporeal shockwave lithotripsy -SWL, retrograde surgery -RIRS, percutaneous nephrolithotomy – PCNL, surgery), complications, and stone-free rates. The primary outcome was stone clearance; complications were graded according to the Clavien-Dindo classification. Categorical variables were compared using Chi-square of Fisher’s exact test.
resultsMedian age was 61 months (IQR 25–105). Nineteen patients (19.8%) had associated urological conditions. 50% had multiple stones. Treatments included SWL (17.7%), URS/RIRS (46.9%), PCNL (19.8%), and surgery (8.3%). Intraoperative complications occurred in 4.2%, early postoperative in 12.5%, and late complications in 11.5%. Stone clearance after the first procedure was achieved in 47.9%. Clearance rates were 58.8% for SWL, 47.8% for URS/RIRS, and 52.6% for PCNL. No statistically significant differences were observed in stone clearance or complication rates among treatments.
conclusionsAll treatments demonstrated safety and efficacy for 10–20 mm pediatric intrarenal stones. Individualized treatment planning, considering stone burden and patient-specific factors, remains essential to optimize outcomes.
