RESUMEN
Objective:To research the relationship of urinary cytology positive rate with the grade and stage of primary ureter uroepithelium cancer.Methods:A total of 104 cases of primary ureter uroepithelium cancer were recruited in this study.The urine of all paitents was collected for preoperative urinary cytology de-tection.The urinary cytology detection rates were compared among different grades and stages of primary ureter uroepithelium cancer.Results:The overall unnary cytology positive rate of primary ureter uroepithelium cancer was 34.26%.The overall urinary cytology positive rate was 43.59%in the advanced stage group and 11.54%in the low stage group,with a significant difference(X2=8.740, P=0.003).The difference in positive rate between the advanced stage group and the low stage group in the high grade with inferior segment group of primary ureter uroepithelium cancer was statistically significant(X2=10.628,P=0.001).The difference in positive rate between the advanced stage group and the low stage group in the high grade group of primary ureter uroepithelium cancer was statistically significant(X2=5.678,P=0.01 7).The difference in positive rate be-tween the high grade group and the low grade group in low stage group of primary ureter uroepithelium can-cer was statistically significant(X2=12.860,P=0.001).Conclusion:The unnary cytology positive rate of primary ureter uroepithelium cancer of high grade and low stage is higher.
