A COMPARATIVE-STUDY BETWEEN ETIOLOGIC FACTORS OF CALCIUM-OXALATE MONOHYDRATE AND CALCIUM-OXALATE DIHYDRATE UROLITHIASIS

A comparative study between different etiological factors of calcium o xalate monohydrate (COM) and calcium oxalate dihydrate (GOD) is presen ted. The most frequent alteration in COD urolithiasis was associated w ith hypercalciuria, whereas in COM urolithiasis was associated with ur inary pH. A comparison between COM and COB groups of stone formers tha t exhibited 1, 2 or 3 alterations was performed. Thus, in individuals with two simultaneous alterations, the association between altered uri nary pH and hypomagnesiuria was the most frequent in the COM group, wh ereas the association between hypercalciuria and altered urinary pH wa s most frequent in the COD group. In individuals with three simultaneo us alterations, the association between hypercalciuria, hyperphosphatu ria and hyperuricuria was most frequent in both COM and COD stone form ers.
