Urinary citrate as a marker of renal function in patients with autosomal dominant polycystic kidney disease.

Introduction: Autosomal dominant polycystic kidney disease (ADPKD) is frequent to find low urinary citrate levels. Recently, it has been suggested that urinary citrate could be a marker of covert metabolic acidosis in chronic kidney disease.

Objective: Our aim was to analyze relationship between urinary citrate levels, renal function, and serum bicarbonate in ADPKD patients.
