Scanning electron microscopic investigations on the morphology and phase conversions of uroliths

Abstract
The most frequent structures of the majority of possible urolith components are assessed by scanning electron microscopic investigations. Typical examples for the conversion of uric acid dihydrate into uric acid, weddellite into whewellite and MgHN4PO4·6H2O into MgNH4PO4·H2O are given.
