1. Anomalous transmembrane anion transport has been observed in erythrocytes of patients with idiopathic calcium nephrolithiasis. 2. To verify whether cation transport is also abnormal, we investigated the frusemide-sensitive Na+ efflux from Na+-loaded erythrocytes and the natriuretic response to acute intravenous frusemide administration in calcium oxalate renal stone formers. 3. Frusemide administration induced a statistically significant smaller increase in the fractional excretion of Na+ in patients than in control subjects. Abnormal kinetic properties of erythrocyte Na+-K+-2Cl− co-transport were observed in approximately 60% of stone formers. The Km for Na+ of Na+-K+-2Cl− co-transport correlated with urinary Ca2+ excretion. 4. The abnormal kinetic properties of Na+-K+-2Cl− co-transport may be relevant for stone formation, hampering renal Ca2+ reabsorption in the distal nephron and determining critical physicochemical conditions for calcium/oxalate crystallization.

1. The demonstration of an inheritable anomaly of erythrocyte oxalate transport in ‘primary’ calcium nephrolithiasis suggested that this disease might be a generalized metabolic disorder characterized by a defect in cellular anion transport. 2. To determine whether this anomaly is restricted to oxalate alone, we studied erythrocyte transmembrane urate self-exchange in calcium-oxalate renal stone formers in whom urinary excretion of uric acid is frequently increased. 3. Abnormal urate self-exchange was found in 30% of the patients. The urate self-exchange rate constant was correlated with 24 h urinary excretion of uric acid; the erythrocyte anomaly was also associated with the frequency of hyperuricosuria and a more intense disease activity. Transmembrane urate self-exchange was inhibited by stilbene and heparan sulphate. Morphazinamide administration did not reduce urinary urate excretion in patients with abnormal urate erythrocyte self-exchange. 4. These findings suggest that hyperuricosuria during calcium-oxalate renal stone disease might be due to a cellular defect in urate transport, and further support the hypothesis that idiopathic nephrolithiasis is a metabolic disorder characterized by a defect in cellular anion transport.
