Intrarenal and central hemodynamics after Grade I-III kidney injury: is there a direct cause-and-effect relationship with posttraumatic arterial hypertension?

Introduction. Mechanical kidney injuries lead to renal dysfunction and vasospastic reaction, resulting in adaptive reactions of the organism, with the possibility of formation of secondary arterial hypertension. Purpose of the study: to determine the types of central gemodynamics, intrarenal blood flow characteristics, correlation interrelations of indices and to estimate the risks of secondary posttraumatic arterial hypertension development after Grade I-III kidney injury. Material and methods. Systemic hemodynamic parameters with identification of blood circulation type and intrarenal hemodynamic parameters were studied in 196 male victims in the posttraumatic period, the control group consisted of 30 men. During statistical processing Pearson correlation coefficients (r) and linear regression coefficient of determination (r2) were additionally calculated.
