Purpose: To estimate a direct association between nephrolithiasis and hepatosteatosis in patients referred to CT due to clinical suspicion of renal colic.

Methods: A 508 non-contrast CT scans were examined for calculi in the kidneys or urinary tract, including measurements of liver attenuation, spleen attenuation, thickness of visceral and subcutaneous fat. Logistic regression examined the association of nephrolithiasis and hepatosteatosis findings.

Results: Nephrolithiasis was found in 421 (83.9%) and hepatosteatosis in 80 (15.7%) cases. Univariate analysis showed a statistically significant association between nephrolithiasis and hepatosteatosis OR=3.24 (95% CI 1.36-7.68), p=0.008.

Conclusions: A significant association was determined between nephrolithiasis and hepatosteatosis.

Background: Radioactive iodine (RAI) is a common treatment for various thyroid diseases. Previous studies have suggested susceptibility of parathyroid glands to the mutagenic effect of RAI and the development of primary hyperparathyroidism (PHPT). We tested the possible link between prior RAI treatment, disease presentation, and treatment outcomes.

This study explores the relationship between 25-hydroxyvitamin D/calcium/alkaline phosphatase (ALP) levels and kidney stone development via cross-sectional and Mendelian randomization (MR) analyses. We used data from the National Health and Nutrition Examination Survey (NHANES) 2013 to 2018 to explore the associations of 25(OH)D metabolite, calcium, and ALP levels with kidney stone development, LDSC analysis to determine the associations between their genetically predicted levels and kidney stone development, and MR analysis to determine the causality of those relationship via genome-wide association studies (GWASs). The cross-sectional study revealed a relationship between ALP levels and kidney stone development (Model 1: OR = 1.
