Computerized tomography-derived body composition metrics are associated with 24-h urine lithogenic parameters.

ABSTRACT:

Background

The relationship between body composition and lithogenic urine parameters remains poorly defined. This study aimed to evaluate associations between computerized tomography (CT)-derived body composition metrics and 24-h urine findings.

Methods

Stone-forming patients in our Nephrolithiasis Database who underwent 24-h urine testing and CT within 120 days were retrospectively reviewed. Skeletal muscle index (SMI), visceral adipose tissue index (VATI), subcutaneous adipose tissue index (SATI) and skeletal muscle density (SMD) were calculated from segmented L3 axial images. Spearman correlations and multivariable logistic regression tested associations between body composition and 24-h urine markers.

Results

Among 443 patients, all body composition metrics demons
