Abstract
The aim of the study: to determine the effectiveness of angiography with renal artery embolization in patients with blunt renal injury (BRI) by the definition of predictors of complications.
Materials and methods. The article presents the results of treatment of 301 patients with isolated BRI, which were divided into two groups: basic (n=171) and control (n=130). The main group consisted of patients with BRI, who were treated from 2004 to 2014, the effectiveness of the treatment which were analyzed prospectively. This group also included 21 patients who underwent angiography with renal artery embolization (RAE). The control group included patients treated from 1989 to 2003, the effectiveness of the treatment which were analyzed retrospectively. Patients of the main group used "the most conservative approach, which included conservative treatment (CT) of hemodynamically stable patients with I–IV degree of severity of the injury. Absolute indications to surgical treatment of patients prospective group was V degree injury to the kidneys and unstable hemodynamics, which is not corrected with conservative methods of treatment.
Results. By mathematical analysis using the statistical package Statiatical Package for the Social Science (SPSS) version 17 was used to determine the value of RAE in patients with BRI. The results of a comparative study show that the predictors RAE with 95% confidence are: hemoglobin level during hospitalization, retroperitoneal hematoma, transfusion intermediaries. In 36 patients of the control group, who were performed surgical treatment, at 36.1% could be RAE.
