Ani S., . and Zakaria M. A., . (2000) Some unique properties of calcium oxalate crystals. [Proceedings Paper]
Abstract
Calcium oxalate is the most commonly found crystal in the human kidney and is also commonly referred to as stones. It exists either as calcium oxalate dihydrate COD or calcium oxalate monohydrate COM the latter is considered its most stable form. It can easily be distinguished from its surface morphology but not many of its surface properties are reported in literature. The aim of this paper is to show that COD exists in more than one form either as cake-like or double-layer cone. COM showed various shapes such as dendrites dumb-bells rosettes plate-like and fruit-like form. From optical microscopic studies both plate-like and fruit-like shapes of COM were hollow or able to adsorb other compounds such as uric acid into their bodies. This indicated that COM was not the most stable form of calcium oxalate as generally believed. The finding highlighted the fact that COM was not only able to adsorb certain compounds but could also expand by introducing the right size chemical compound into its body. This makes it possible to develop a new technique in distinguishing the stone to smaller size for easy removal from the human urinary system.
