Abstract: To study the clinical feature diagnosis and treatment of upper urinary epithelial cell carcinoma, 42 cases of upper urinary transitional cell carcinoma as a result of pathological verification within 10 years were reviewed and analyzed. And summary and comparison were made in progress for its clinical feature, urine cytology examination results, the examination of image feature and cystoscope. Eleven cases had multi-organ relapse in the meantime, 40 cases of patients were operated, 34 cases of patients were followed up postoperatively. Urine cytology examination positive rate was 66.7%, and it could reach 92.9% after irrigation of retrograte intubation. CT positive rate was 85.7%. Six cases had bladder tumor relapsed after operation. Urine Cytology examination is the idiosyncratic qualitative diagnosis method, the pyelic Urine can raise the positive rate, CT examination has important value in orientation and stage of cancer. Multi-organs trend should be handled seriously, the treatment should be radical excision mainly, and the cystoscope examination should be carried out routinely.
