The functional state of the kidneys in obesity (according to the data of radioisotope renoangiography)

Despite the fact that significant advances have been made in the study of obesity [3, 4, 5, 12-17], many aspects of this complex disease remain insufficiently illuminated. In the pathogenesis of metabolic disorders in obesity, the disorder of water-electrolyte metabolism, the mechanisms of which still remain unclear, is largely involved. There is no doubt that the kidneys play an important role in maintaining water-electrolyte balance. The state of the kidneys in obesity has already been studied by a number of foreign researchers [11, 17] using clearance tests and tests generally accepted in nephrology (urinalysis, blood analysis, Zimnitsky test, determination of the residual nitrogen content in the blood). However, these tests can only give an idea of ​​the total activity of the kidneys, without differentiating the functional state of each of them.
