ABSTRACT

The diagnostic value of lymphography and computed tomography (CT) in the assessment of lymph node invasion by bladder cancers has been compared on the basis of 30 observations. Although computed tomography apparently yields better results (reliability 93%) than lymphography (reliability 87%), these findings have no statistical significance. The study of literature shows that the statistical exploitation of the results was seldom carried out. The combination of both exploration techniques seems to improve predictive values, but this improvement was not statistically significant in our study.
