Heterozygous cystinuria and calcium oxalate urolithiasis.
To evaluate the incidence of heterozygous cystinuria in patients with primary and recurrent calcium oxalate stone disease 24-hour urine samples from 140 patients were examined. The frequency of heterozygous cystinuria in this study was only 1.4 per cent (2 patients). The frequency of other metabolic disorders was in accordance with other reports: hypercalciuria (32 per cent), hyperuricosuria (32 per cent) and hyperoxaluria (17 per cent).
