尿路上皮增生Urothelium Hyperplasia · 肾脏 · 泌尿系统 · NTP ntp-0152
诊断要点:尿路上皮增生应当被诊断并给予严重程度分级。在炎症区域或存在结石的情况下,病理学家应运用其判断来决定继发性尿路上皮增生是否显著到足以需要单独诊断。
病变描述
肾盂(与肾乳头相对或位于肾穹窿处;Figure 1)的尿路上皮增生(urothelial hyperplasia)可作为化学诱导性病变观察到,也可作为与炎症相关的再生性病变(Figure 2)或继发于尿路上皮损伤的病变观察到。增生灶可为局灶性(focal)、多灶性(multifocal)或弥漫性(diffuse)。
诊断与分级建议(NTP 共识)
尿路上皮增生应当被诊断并给予严重程度分级。在炎症区域或存在结石的情况下,病理学家应运用其判断来决定继发性尿路上皮增生是否显著到足以需要单独诊断。相关链接:肾脏 - 结石;肾脏 - 乳头,上皮 - 增生

Comment:
Urothelial hyperplasia in the renal pelvis (opposite the renal papilla or in the renal fornices; Figure 1 ) may be observed as a chemically induced lesion or as a regenerative lesion associated with inflammation ( Figure 2 ) or secondary to an injury to the urothelium. Hyperplastic foci can be focal, multifocal, or diffuse.
Recommendation:
Urothelial hyperplasia should be diagnosed and given a severity grade. In areas of inflammation or with the presence of calculi, the pathologist should use his or her judgment in deciding whether secondary urothelial hyperplasia is prominent enough to warrant a separate diagnosis.
