Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease, ranging from pure steatosis to non-alcoholic steatohepatitis and ultimately to liver cirrhosis. In our study, adult NAFLD patients did not have different oxalate excretion values [ -0.26 (95% CI -1.59-1.08), I P i =.681] and only altered urinary ammonium and magnesium excretions were found as proposed risk factors for nephrolithiasis (Fig. Our findings indicate the need for further prospective studies to compare the characteristics of NAFLD patients with and without nephrolithiasis and its incidence at different degrees of NAFLD severity to expand on the observations reported here.
