Abstract
Relevance. The article is devoted to contrast-enhanced ultrasound in patients at different stages of minimally invasive (radiofrequency ablation, RFA) treatment of a kidney tumor.
Objective. To increase the effectiveness of minimally invasive treatment of malignant tumors of the kidneys with the use of a contrast agent in ultrasound examination.
Materials and methods. The group included 32 (100%) patients with malignant tumors of the kidneys who were denied surgical treatment due to the presence of severe concomitant somatic pathology or the presence of one kidney. In 3 patients, an allergic reaction to the contrast used in CT and MRI was observed, therefore, dynamic observation was carried out only on the basis of data obtained during contrast-enhanced ultrasound. Before RFA and at all stages of dynamic control, all patients underwent contrast-enhanced ultrasound examination. In 29 patients, results one month after ablation were compared with contrast-enhanced MRI or CT.
Conclusions. The work showed that contrast-enhanced renal ultrasound can effectively evaluate the effectiveness of RFA of kidney malignancies in patients who were denied surgical treatment.
