Kidney tumors are very common nowadays. Tumor in the patient's kidney; may vary in size and region. If the tumor cannot be detected correctly by a specialist, late diagnosis and early treatment are not applied, patients are at risk of death. In such cases, the importance of technology becomes clear. With the rapid development of technology, the concept of artificial intelligence has become the center of our lives in recent years. Medicine is also one of the areas where this concept is used the most. Computed tomography medical imaging devices are widely used in the detection of kidney tumors. Within the scope of this study, images obtained by computerized tomography device were used. Convolutional Neural Network (CNN) was used as the classifier model for kidney tumor detection analysis. Performance comparison analysis between them was made using VGG16, VGG19 and ResNET50 models. Python and Tensorflow, Keras and OpenCV libraries were used as the software language of the application. As a result of the analysis, it was seen that it was successfully performed in the detection of kidney tumors
