Papillary stones are small, rounded concretions with one smooth convex face and one concave face which corresponds to its implantation on the papilla and in which a whitish Randall's plaque is often present. Eighty-seven papillary stones were studied with stereoscopic, scanning electron microscopic and x-ray dispersive energy analysis. Sixty-three stones had a plaque and 13 of these showed calcified renal tubules that demonstrated their intrapapillary origin and a link between partial papillary nephrocalcinosis and renal stones.
乳头结石是小的、圆形的凝结物，有一个光滑的凸面和一个凹面，凹面与它在乳头上的附着部位相对应，并且通常存在白色的兰德尔斑。对87颗乳头结石进行了立体显微镜、扫描电子显微镜和X射线色散能分析研究。63颗结石有斑块，其中13颗显示有钙化的肾小管，这证明了它们的乳头内起源以及部分乳头肾钙质沉着症与肾结石之间的联系。
