Respective influence of calcium and oxalate urine concentration on the formation of calcium oxalate monohydrate or dihydrate crystals

Clinical interest for the identification of the crystalline phase of CaOx, either monohydrate (COM) or dihydrate (COD), in crystalluria analysis is debated. In the present study, we simultaneously determined calcium and oxalate concentration and identified the two crystalline phases of CaOx crystals in 1288 first morning urine samples from 407 CaOx stone formers with crystalluria.
