Predictive value of family history of kidney stones for metabolic abnormalities and stone composition.
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. 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
backgroundFamily history of kidney stones is a known risk factor for nephrolithiasis, but its specific association with metabolic abnormalities and stone types remains unclear. This study aimed to determine if family history predicts distinct metabolic profiles or stone compositions.
methodsWe retrospectively analyzed 101 patients from a specialized stone clinic (2022-2025), stratified by family history. Metabolic abnormalities (hypercalciuria, hyperoxaluria, hyperuricosuria, hypocitraturia, cystinuria, hypomagnesuria) and stone compositions were compared using chi-square tests. Logistic regression, adjusted for age, gender, body mass index (BMI), diabetes, hypertension, and metabolic syndrome, assessed independent associations.
resultsPatients with family history had higher prevalence of hypercalciuria (49.2% vs. 30.0%, p = 0.022) and hyperoxaluria (27.9% vs. 12.5%, p = 0.034). Among 90 patients with stone data, Calcium Oxalate (CaOx) monohydrate was more common with family history (65.6% vs. 47.5%, p = 0.036). Logistic regression confirmed family history as an independent predictor of hypercalciuria (OR 2.15, 95% CI 1.03-4.50, p = 0.041) and CaOx monohydrate (OR 2.05, 95% CI 1.01-4.17, p = 0.047), with a trend for hyperoxaluria (OR 2.62, 95% CI 0.99-6.92, p = 0.052). No significant differences were found for other abnormalities or stone types, with wide CIs for cystinuria (n = 4).
conclusionFamily history of kidney stones is associated with increased risk of hypercalciuria, hyperoxaluria, and CaOx monohydrate stones, suggesting a genetic predisposition. These findings support using family history for risk stratification and targeted metabolic evaluations to prevent recurrence, warranting further genetic studies.
