| pubmed-article:8045208 | pubmed:abstractText | From May 1983 to 1992, 15 patients with urinary epithelial squamous cell carcinoma in renal pelvis (7) and in bladder (8) were treated. Eleven of them were complicated by urinary tract stone. Of the 15 patients, 8 were misdiagnosed as having simple urinary stone and 1 renal tuberculosis. It is suggested that active treatment for urinary stones be used to prevent the occurrence of squamous cell carcinoma and that possibility of concomitant epithelial tumor in patients with long-term and large urinary stones be considered. | lld:pubmed |
