There are several factors involved in its pathogenesis including insufficient dietary habits and fluid intake. Therefore, we conducted a systematic review and meta-analysis to compare between dietary intake across populations and recurrent urinary tract stones. This systematic review and meta-analysis aims to compare the associations between dietary intake across populations and recurrent kidney stones. Methods: Systematic search up to March 2023 were conducted through PubMed, Scopus, EMBASE. The systematic review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Means and standard deviation of the nutrient intakes were extracted in patients with urinary stone disease group and control group. Results: Seven articles were further assessed with two articles were assessed through meta-analysis. Two studies showed that high sodium intake [SMD = 0.29 95% CI = -0.13, 0,71] was found in patient with urinary stone disease, while high water intake [SMD = -0.40 95% CI = -1.14, 0.34] was found in the control group. Conclusion: Animal protein, processed meat, sodium, and sugary beverages were associated with an increased risk of developing urinary stones, whereas vegetable protein and water intake were associated with a decreased risk.
