Urothelial neoplasms occur with varying frequency at different sites along the urothelial tract. Approximately 5% of urothelial neoplasms occur in the kidneys and ureters, while the majority of these tumors occur in the urinary bladder. Consequently, urothelial disease of the bladder has been evaluated to a greater extent than urothelial tumors elsewhere, and many of the features of bladder urothelial neoplasms have been applied to these tumors at other sites. While the classification of urothelial neoplasms is the same for tumors in the bladder, kidney, and ureter, there are some features of urothelial neoplasms of the kidney and ureter that are unique to these sites. An epidemiologic, pathologic, and clinical review of urothelial neoplasms of the kidney and ureter is presented.
尿路上皮肿瘤在尿路的不同部位发生频率各异。约5%的尿路上皮肿瘤发生在肾脏和输尿管，而这些肿瘤的大多数发生在膀胱。因此，膀胱尿路上皮疾病的评估程度比其他部位的尿路上皮肿瘤更高，膀胱尿路上皮肿瘤的许多特征也被应用于其他部位的这些肿瘤。虽然膀胱、肾脏和输尿管肿瘤的尿路上皮肿瘤分类相同，但肾脏和输尿管尿路上皮肿瘤有一些该部位独有的特征。本文对肾脏和输尿管尿路上皮肿瘤进行了流行病学、病理学和临床综述。
