Li CC, et al. - Researchers compared the clinical characteristics of uric acid stones and their potential risk for chronic kidney disease (CKD) via analyzing 401 patients (196 with uric acid stone and 205 without) from their database of patients with urolithiasis. The patients were analyzed for the clinical demographic features, stone location, urine chemistries, and renal function. The independent predictors of poor prognoses in CKD comprised age over 60 years, female sex, hyperuricemia, and uric acid stone. Findings thus suggest the existence of an association between uric acid stones and higher prevalence of CKD. Close monitoring of renal function during follow-up is thus suggested for patients with uric acid stones.
