About

The purpose of this study is to determine whether febuxostat and benzbromarone could protect renal function, and which one could be better.

Full description

Chronic kidney disease patients with hyperuricemia and glomerular filtration rate (GFR) 20-50 ml/min were treated by febuxostat or benzbromarone. Follow up the changes of serum uric acid, serum creatinine and GFR levels. Compare the effects on renal function of these two drugs.
