Abstract

The study aimed to explore the association between the ZJU (Zhejiang University) index and the prevalence of kidney stones in Chinese adults. Electronic health records of individuals undergoing routine physical examinations at Wuhu Second People's Hospital between January 2021 and June 2024 were retrospectively analyzed. Participants were divided into kidney stone recurrence and non-recurrence groups. Data on biochemical parameters, hypertension, and diabetes history were collected, and group differences were assessed using the chi-square test or Kruskal-Wallis rank-sum test. Logistic regression, propensity score matching, and dose-response curve modeling were used to evaluate the relationship between the ZJU index and kidney stone prevalence. Among 5,104 participants aged over 18 years, 462 were diagnosed with kidney stones. After adjusting for confounders, a higher ZJU index was identified as an independent risk factor for kidney stone prevalence (odds ratio [OR] = 1.05, 95% confidence interval [CI]: 1.02-1.08). Propensity score-matched analysis further confirmed this association (OR = 1.09, 95% CI: 1.04-1.13). Dose-response analysis revealed a positive linear relationship between the ZJU index and kidney stone recurrence. These findings suggest that elevated ZJU index levels are associated with a higher prevalence and recurrence of kidney stones, highlighting its potential as a clinical tool for identifying and managing at-risk patients.

期刊介绍： Official Journal of the International Urolithiasis Society The journal aims to publish original articles in the fields of clinical and experimental investigation only within the sphere of urolithiasis and its related areas of research. The journal covers all aspects of urolithiasis research including the diagnosis, epidemiology, pathogenesis, genetics, clinical biochemistry, open and non-invasive surgical intervention, nephrological investigation, chemistry and prophylaxis of the disorder. The Editor welcomes contributions on topics of interest to urologists, nephrologists, radiologists, clinical biochemists, epidemiologists, nutritionists, basic scientists and nurses working in that field. Contributions may be submitted as full-length articles or as rapid communications in the form of Letters to the Editor. Articles should be original and should contain important new findings from carefully conducted studies designed to produce statistically significant data. Please note that we no longer publish articles classified as Case Reports. Editorials and review articles may be published by invitation from the Editorial Board. All submissions are peer-reviewed. Through an electronic system for the submission and review of manuscripts, the Editor and Associate Editors aim to make publication accessible as quickly as possible to a large number of readers throughout the world.
