The capacity of computed tomography
 in the preoperative determination of surgery
 volume in kidney tumors

Abstract

Relevance: Computed tomography allows detecting
 small tumors. However, surgical tactics cannot always be determined in advance.
 The purpose of the research was to assess the capacity
 of computed tomography in preoperative determination of
 surgery volume in kidney tumors.
 Results: 548 patients were treated for kidney neoplasms.
 They were divided into three groups by computed tomography based on the R.E.N.A.L. scale: with a high risk of complications – 265 patients (48.4%), medium risk – 107 (19.5%),
 and low risk – 176 (32.1%). All operations were performed in
 the planned volume depending on the identified risk group
 for complications and resectability of kidney neoplasms; no
 changes to the plan of surgical interventions were made. The
 preoperative assessment of the kidney angioarchitectonics
 and the tumor relation to the pyelocaliceal system and the
 organ parenchyma helped determine the surgery volume
 and the possibility for organ-reserving interventions in 283
 patients and radical nephrectomy in 265 patients.
 Conclusion: Such a highly informative method as computed tomography made allows early detection of small-sized kidney tumors to provide an opportunity for organ-preserving surgery and improved treatment outcome
