We make an analysis by means of a Scanning Electromicroscope, of the ultrastructure of 15 Primary Prostate stones. The components identified were: Carboapatite in 14 stones, Hydorxyapatite in 3, Whitlockite in 4 and Wedellite in 2 stones. The ultrastructural findings have enabled us to classify them as follows: 1. Hydroxyapatite stones, which we call "Crystalline", the rarest, due to the predominance of the inorganic component. 2. Carboapatite stones, which possess a great deal of organic material and which we subdivide into "Amylaceous" for those which possess some ovoid formations which appear to us to correspond to amylaceous bodies and "non-amylaceous" for those without them.

D008855 Microscopy, Electron, Scanning Microscopy in which the object is examined directly by an electron beam scanning the specimen point-by-point. The image is constructed by detecting the products of specimen interactions that are projected above the plane of the sample, such as backscattered electrons. Although SCANNING TRANSMISSION ELECTRON MICROSCOPY also scans the specimen point by point with the electron beam, the image is constructed by detecting the electrons, or their interaction products that are transmitted through the sample plane, so that is a form of TRANSMISSION ELECTRON MICROSCOPY.
