Calculi removed from human prostates affected with nodular hyperplasia were analyzed with scanning electron microscopy and EDAX system. The general spectrum was made up of Na, Al, Mg, S, P, Ca and Zn. Two types of stone were identified morphostructurally and microanalytically: calculi type I of nodular surface with high peaks of S, and calculi type II polyfaceted with high peaks of P and Ca. Their formation from corpora amylacea and/or exogenous constituents is discussed. The superficial deposit of Zn suggests its incorporation from the prostatic liquid and does not seem to play an important role in the genesis.
对从患有结节性增生的人类前列腺中取出的结石进行了扫描电子显微镜和能谱仪分析。其一般光谱由钠、铝、镁、硫、磷、钙和锌组成。从形态结构和微观分析上鉴定出两种类型的结石：结节表面的I型结石，硫含量高；多面体型的II型结石，磷和钙含量高。讨论了它们由前列腺淀粉样小体和/或外源性成分形成的情况。锌的表面沉积表明它是从前列腺液中掺入的，似乎在结石形成过程中不起重要作用。
