肾盂鳞状细胞癌较其它细胞癌为少见。一般认为,本病是因长期肾盂感染和肾结石慢性刺激引起移行细胞上皮化生,数年后导致鳞状化生直至恶变。作者前瞻性研究1970～1985年间经组织学证实的11例肾盂鳞状细胞癌患者。术前检查包括尿培养、IVP、肾血管造影及CT。此外对手术所见、病理特点和治疗结果亦进行了研究。结果(1)临床特点:11例患者中男5例,
Renal squamous cell carcinoma is rarer than other cell carcinomas. It is generally believed that the disease is caused by long-term renal pelvis infection and chronic stimulation of kidney stones caused by transitional cell epithelial metaplasia, leading to squamous metaplasia until malignant transformation after several years. The authors prospectively studied 11 cases of renal peltate squamous cell carcinoma confirmed by histology from 1970 to 1985. Preoperative examinations included urine culture, IVP, renal angiography, and CT. In addition, the surgical findings, pathological features and treatment outcomes were also studied. Results (1) Clinical characteristics: There were 5 males in 11 patients.
