We present what, to our knowledge, is the first reported case of nephrogenic metaplasia of the ureter. Nephrogenic metaplasia involves the transitional epithelium of the urinary tract and results in the formation of epithelial tubules, which are histologically similar to renal tubules. Special stains demonstrated both intracellular and intraluminal mucin. Ultrastructurally, the lesion consisted of epithelial cells with sparse microvilli and a thick basal lamina. The criteria for diagnosis and differentiation from carcinoma are discussed.
据我们所知，我们报告了首例输尿管肾源性化生病例。肾源性化生累及尿路移行上皮，导致上皮小管形成，其组织学特征与肾小管相似。特殊染色显示细胞内和管腔内均有黏液。超微结构上，病变由微绒毛稀疏且基膜增厚的上皮细胞组成。文中讨论了诊断标准以及与癌的鉴别要点。
