Abstract

The frequency of a high protein intake and of associated urinary abnormalities was assessed in 115 male calcium stone formers with normal renal function. The patients were divided into three groups according to their urinary urea/creatinine (Cr) ratio: Group I (n=41), urea/Cr <25 (urea excretion, 368±87 mmol/day; protein intake, 0.95±0.26 g/kg/day); Group II (n=38), urea/Cr 25–30 (urea excretion, 441±104 mmol/day; protein intake, 1.09±0.27 g/kg/day); and Group III (n=36), urea/Cr >30 (urea excretion, 550±103 mmol/day; protein intake, 1.39±0.24 g/kg/day). Hypercalciuria (Ca/Cr >0.45) occurred in 17%, 45%, and 61% of the patients, respectively (p<0.01).
