Metabolic abnormalities, recurrence risk, patient and stone characteristics in calcium-based pediatric stone formers: is there any association?
Article in World journal of urology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 the association between serum and urinary metabolic abnormalities, stone recurrence risk, and patient and stone characteristics in calcium-based pediatric stone formers; aiming to refine the indication for metabolic evaluation in pediatric urolithiasis population. PATIENTS AND
methodsThe study included 80 pediatric patients < 18 years with a history of intervention for calcium-based stones at the Urology and Nephrology Center, Mansoura University, Egypt, between 2001 and 2022. Electronic database was reviewed for patient and stone characteristics. Serum and 24-hour urinary metabolic evaluation was done. The primary outcome was to assess the association between serum and urinary metabolic abnormalities, and patient and stone characteristics. A secondary outcome was to assess risk factors associated with stone recurrence.
resultsSerum and urinary metabolic abnormalities were present in 31.25% and 73.75% of the study population, respectively. There was no significant difference between normal and abnormal groups of serum and 24-hour urine chemistry in relation to all assessed patient and stone characteristics. However, there was a significant association between stone laterality and risk of recurrence (HR: 3.801, 95% CI: 1.239–11.662, p = 0.02); being ~ 3.8 times higher with bilateral urolithiasis (78.3% vs. 21.8% with unilateral urolithiasis).
conclusionRoutine serum and 24-hour urinary metabolic evaluation is still indicated in all pediatric calcium-based stone formers; being a high-risk population. However, the recurrence risk is higher in patients with bilateral urolithiasis. So, in case of limited resources, metabolic evaluation could be restricted to this group of patients only.
