A comparative study between etiological factors of calcium oxalate monohydrate and calcium oxalate dihydrate urolithiasis.
A comparative study between different etiological factors of calcium oxalate monohydrate (COM) and calcium oxalate dihydrate (COD) is presented. The most frequent alteration in COD urolithiasis was associated with hypercalciuria, whereas in COM urolithiasis was associated with urinary pH. A comparison between COM and COD groups of stone formers that exhibited 1, 2 or 3 alterations was performed. Thus, in individuals with two simultaneous alterations, the association between altered urinary pH and hypomagnesiuria was the most frequent in the COM group, whereas the association between hypercalciuria and altered urinary pH was most frequent in the COD group. In individuals with three simultaneous alterations, the association between hypercalciuria, hyperphosphaturia and hyperuricuria was most frequent in both COM and COD stone formers.
