ИНДЕКС РЕЗИСТЕНТНОСТИ В ДИАГНОСТИКЕ ЗАБОЛЕВАНИЙ ПОЧЕК – ВОЗМОЖНОСТИ И ОГРАНИЧЕНИЯ

The paper summarizes the data obtained by different investigators on the clinical application of Doppler index of resistance in uronephrology: acute urinary tract obstruction, non-obstructive kidney diseases, kidney transplants, only one kidney, kidney tumor, violations of intrarenal hemodynamics caused by the central hemodynamic changes. Recognized that the index of resistance can be effectively used in the study of renal blood flow in a number of nosology. We present our own data, indicating the need for a systematic approach to the study of renal hemodynamics. According to syndromes the state is reviewed, accompanied by changes in blood flow in the main renal arteries with increased resistance index and with its decline, and their pathophysiological aspects. Is made a reasoned conclusion that the calculation of resistance index values fully into account the parameters of central hemodynamics such as the magnitude of the pulse rate, blood pressure, cardiac output; of intracardiac hemodynamics (with valvular heart diseases), systolic/diastolic dysfunction, age-related changes of the kidneys, the availability of system disease patients makes it more correct approach to its clinical application.
