Abstract:

The work was aimed at determining the possibilities of multislice computed tomography (MSCT) in diagnosis and staging of acute pyelonephritis (AP) for studying the role of concomitant congenital renal anomalies in development of AP and therapeutic decision-making. A total of 59 patients presenting with AP and suspected pyodestructive complications were subjected to MSCT, with 7 seven of these having undergone it twice in order to control therapeutic efficacy. The study showed that ultrasonography as well as excretory urography are not always informative enough as to the possibility of revealing purulent forms of an inflammatory process having developed on the background of renal developmental defects, especially anomalies of the shape, localization, and structure. The obtained findings made it possible to define proper indications for performing MSCT in patients with AP. Improved diagnosis achieved by means of MSCT made it possible to decrease the number of operations and avoid unnecessary nephrectomies.

Abstract:

Radiofrequency (RF) ablation is a minimally invasive method. Application of RF ablation allowed to expand indications for more radical treatment of kidney tumors in patients, whom traditional nephrectomy or kidney resection are impossible, due to extremely adverse somatic status

Efficiency and safety of RF ablation are significantly increased if preceded in combination with superselective occlusion of blood vessels, supplying the tumor. We possess the experience of application of superselective embolization in combination with RF ablation of two patients with kidney tumors. In both cases a good result of combined treatment has been observed.

This combination (superselective embolization + RF ablation) can be an alternative to open operation on kidney in number of patients, expanding the arsenal of modern minimally invasive kidney tumor's treatment methods.
