Аннотация

Aim of the research: According to the comparison of data of ultrasound diagnosis and computer tomography with the results of intraoperational findings and histology research; the sensibility degree, specific and effectiveness of that methods should be identified with the assessment of renal carcinomas local dispersion for each given research methods. Materials and methods: The results of examination and therapy of 170 patients who suffered from renal cell carcinoma were addressed to the urology department of Republican Center of Oncology and to the Republican Center of Urology from the 2010 till the 2015 constitute the basis for the given research. It is worth mentioning that 104 of patients were males (61,2%), whereas the number of females were just 66 (38,8%). The age of patients fluctuated from 22 until 83 years old, the average age was 57,5±6,8. Results: The given data about the assessment of the results of renal carcinoma patients' ultrasound diagnostic showed that the sensibility of USS during the identification of the T1 stage constitute 66,7%, while the figure for T2, T3 and T4 is 68,9%, 83,3% and 100% respectively. As regard the specificity of USS during identification of the T1 stage is 100%, this ratio is 95,7% for T2, 96,5% for T3 and 97,1% for T4. The diagnostic accuracy of the USS in the determination of T1 stage is 94,2%, T2-80.8%T3-94,2%T4-97,l%. The tomography's results of the patients who suffer from renal carcinoma showed that the sensibility rate during the determination of the T1 stage is 90%, T2-97,5%, T3 and T4 - 100%. Specificity of tomography in the determination of T1 and T2 stages is 100%, T3-87,3% and T4-88,5%. The diagnostic accuracy of tomography in the determination of T1 stage is 87,6%, T2-98,9%, T3-89,9% and T4- 88.8%. Conclusion: The obtained results of the research showed that inclusion of modern diagnostic methods such as ultrasound, X-ray, tomography into complex plan of the patients' examination who suffer from renal cell carcinoma allows to determine quite effectively the degree of cancer prevalence and distinguish local cancer from primarily-generalized tumor forms. This improvement, in turn, affects the tactic of treating this category of patients.
