Injury as a cause of nephrectomies in the regional aspect

Abstract

The work is based on the materials of official statistical reports and covers the dynamics of nephrectomies and, in particular, kidney injury as its cause. Data for ten years (2009-2018) are analyzed, with two five-year periods. This makes it possible to trace not only the nature of changes in absolute indicators over a long period, but also to determine their intensity over the years of study. The situation was assessed in Ukraine as a whole and in the regional aspect. A well-known system of indicators was used: absolute increase (decrease), growth rate (decrease), extensive coefficients, according to which the internal structure was studied. When it was necessary to determine the reliability of the difference between the two parameters, the Student's criterion was calculated. There is a positive trend in the form of a decrease in the total number of nephrectomies in Ukraine as a whole by 5.2% to 2926 operations in 2018. In contrast to the previous five years, when there was an increase (by 5.2%) from 4110 to 4326 in 2013. The percentage of injuries in the structure of nephrectomies did not exceed 2.5% all years of the study. It is characterized by a decrease in each of the periods - its rate was 21.8% and 28.6%, respectively, resulting in an average of 84 ± 6 and 62 ± 5 operations. Regional features on the frequency of injuries are revealed. The difference was an increase of 4 times to 8 areas in 2014-2018, in which there were no kidney injuries that led to organ-bearing operations, while in the previous five years, on the contrary, there was a decrease from 6 to 3. However, the number of areas up to 5 cases per year of kidney injuries, which resulted in nephrectomy, has decreased in the last 5 years (from 76.0% to 56.0%) against their growth over the past five years (from 52.0% to 68.0%). Areas that stand out among others by the number of injuries have been identified. These include mainly those where the mining industry is developed (Dnepropetrovsk, Donetsk, Lugansk, Lviv, Zaporozhye, Rivne).
