title: [Comparative study of urinary calcium, oxalate and uric acid in calcium oxalate lithiasis].
abstract: The purpose of this study was to determine and to compare the frequency of hypercalciuria, hyperoxaluria and hyperuricosuria in 49 patients with a pure or mixed calcium oxalate urolithiasis. During this study, all patients were on a normal diet and had no special disease or medication. We noted that hypercalciuria (35%) and hyperoxaluria (24%) were more often associated (18%) than isolated (8 and 2%). They were more frequent in mixed stones (44% et 39%) than in pure one (29% and 16%). Hyperuricuria (39%) had a same frequency wathever the renal stone type may be. A same frequency was noted when hyperuricuria was associated with hypercalciuria and hyperoxaluria (12%) or isolated (14%). None of these three biologic disturbances was observed in 45% of our patients.
