Highlights
- •Significant association between nephrolithiasis and hepatosteatosis detected by CT for suspected renal colic.
- •Significantly higher chance of calculi was found in patients with fatty liver.
- •Significant association between nephrolithiasis and obesity by CT measurements of visceral fat.
- •Fatty liver possibly an intermediate factor influencing calculi creation.
Abstract
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.
