An electron optical investigation of the morphology of the colloidal matrix of renal and vesical urinary calculi revealed the presence of several morphologic forms hitherto unknown. Earlier light microscopic studies indicated that the matrix exists either as fibrils or as an amorphous matrix. The electron micrographic scanning of specimens of calculi revealed the following matrix morphologies: (i) flaky, (ii) serrated, (iii) perforated (globular), (iv) hollow tubular, (v) fibrillar, (vi) cylindrical, and (vii) pear-drop shaped. Crystalline matter was not associated with flaky and serrated matrix particles. However, some matrix particles of perforated (globular), fibrillar, and cylindrical morphologies were found to be calcified.
对肾和膀胱尿路结石胶体基质形态的电子光学研究揭示了几种迄今未知的形态形式。早期的光学显微镜研究表明，基质以纤维状或无定形基质的形式存在。结石标本的电子显微镜扫描揭示了以下基质形态：（i）片状，（ii）锯齿状，（iii）穿孔（球状），（iv）中空管状，（v）纤维状，（vi）圆柱状，以及（vii）梨滴状。结晶物质与片状和锯齿状基质颗粒无关。然而，发现一些穿孔（球状）、纤维状和圆柱状形态的基质颗粒有钙化现象。
