CLINICAL AND DIAGNOSTIC CAPABILITIES OF ULTRASOUND EXAMINATION AND COMPUTED TOMOGRAPHY IN THE RADIOLOGICAL DIAGNOSIS OF MALIGNANT TUMORS OF THE KIDNEY

Abstract

Malignant tumors of the kidney represent a significant clinical challenge in modern oncology and radiology due to their often asymptomatic progression and late clinical manifestation. Early and accurate detection of renal malignancies plays a crucial role in improving patient prognosis, guiding treatment strategies, and reducing mortality rates. In this context, radiological imaging methods have become indispensable tools for the diagnosis, staging, and monitoring of renal tumors. Among these methods, ultrasonography (US) and computed tomography (CT) occupy a central place because of their high diagnostic sensitivity, noninvasive nature, and ability to provide detailed visualization of renal structures. This study examines the clinical and diagnostic capabilities of ultrasound examination and computed tomography in the radiological assessment of malignant kidney tumors. Particular attention is given to the role of these imaging modalities in the early detection of renal neoplasms, differentiation between benign and malignant lesions, evaluation of tumor localization, size, vascularization, and the extent of invasion into surrounding tissues and organs. Ultrasound imaging serves as an accessible and cost-effective primary screening tool, allowing rapid identification of suspicious renal masses and guiding further diagnostic procedures. Computed tomography, on the other hand, provides comprehensive cross-sectional imaging, enabling precise assessment of tumor morphology, enhancement patterns, metastatic spread, and involvement of adjacent anatomical structures. The integration of ultrasonography and computed tomography significantly enhances diagnostic accuracy and contributes to the development of optimal clinical management strategies for patients with renal malignancies.
