Association between nephrolithiasis and fatty liver detected on non-enhanced CT for clinically suspected renal colic.
OBJECTIVE
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.
