РАЗРАБОТКА МЕТОДА ОЦЕНКИ РЕАБСОРБЦИИ НАТРИЯ ДЛЯ ВЫЯСНЕНИЯ ФУНКЦИОНАЛЬНОГО СОСТОЯНИЯ ПЕРЕСАЖЕННОЙ ПОЧКИ

Sodium reabsorption and sodium consumption (daily sodium excretion) were studied in 63 health volunteers and 100 recipients of kidney allografts. We elaborated the nomogramm for de fi nition of sodium reabsorption with con fi dence interval 95% and proposed to use T-score CNa/GFR for a quantitative estimation of sodium reabsorption. There was a direct line dependence between sodium fractional excretion (CNa/GFR) and T-score CNa/GFR in kidney allograft recipients with good function and chronic rejection of kidney allograft (R = 0,86; р < 0,01; Yx = 0,593 + 0,64x; R = 0,97; р < 0,01; Yx = 0,147 + 1,146 х and R = 0,97; р < 0,01; Yx = 0,21 + 0,69 х , respectively). In recipients with good function of kidney allograft the regression coef fi cient was signi fi cantly higher, than in health volunteers ( р < 0,01). In the group of recipients with chronic transplant rejection a free member of regression equation was signi fi cantly higher, than in health volunteers ( р < 0,01). Consequently, exactness of sodium reabsorption estimation after kidney transplantation is not suf fi cient without calculation of sodium consumption.
