METHODS: This retrospective study included 163 kidney stone-formers and 168 age- and sex-matched control participants without urolithiasis and histories of urolithiasis. The clinical data including age, gender and comorbidities were collected. Aortic calcification index (ACI) of aorta abdominalis, bone mineral density (BMD) of the first lumbar vertebra and the attenuation of renal papillary tips were measured in CT. Multivariate logistic regression analysis was performed to the correlation among ACI, the attenuation of renal papillary tips and nephrolithiasis. Additionally, through the GEO database, the gene expression analyses of aortic calcification (GSE100927) and nephrolithiasis (GSE100927) were performed to evaluate the inner connection in the level of genetic expression. RESULTS: These data showed that the stone-formers had the higher attenuation of renal papillary tips. There was no significant difference in the prevalence of abdominal aortic calcification, however, ACI of participants with abdominal aortic calcification was significantly higher in the stone group. Multivariate logistic regression analysis showed that ACI and the attenuation of renal papillary tips were significantly correlated with nephrolithiasis. Through bioinformatics methods, the same Differentially Expressed Genes of 8 upregulated genes and 17 downregulated genes were screened out and we found that some important signaling pathways were activated in both nephrolithiasis and arterial calcificatio. CONCLUSIONS: This study demonstrates that the stone-formers have the higher attenuation of renal papillary tips, which gives us a hint that the higher attenuation of renal papillary tips may predict the occurrence nephrolithiasis and is supposed to be a junction between nephrolithiasis and arterial calcification. A significant correlation between aortic calcification and nephrolithiasis was proved again and some important genes and signaling pathways were considered to be the inner connection between nephrolithiasis and arterial calcification.
