Inhibited Precipitation and Growth of Ca-Oxalate Crystals in the Presence of the Alkaline Salts of Some Polyhydroxycarboxylic Acids
About 70–90% of renal calculi are composed of poorly soluble salts of calcium and magnesium. Among them 65–75% are calcium oxalate stones (whewellite and weddellite) and the remaining 15–25% are calcium phosphate stones (apatite, brushite, whitlockite and monetite) or magnesium-ammonium-phosphate (struvite) and magnesium phosphate (newberyte and bobierrite) calculi. Only uric acid, uric acid-dihydrate, ammonium urate and sometimes cystine concrements can be dissolved perorally. The chemolitholysis of the calcium and magnesium urinary calculi is still an unresolved problem.
