Summary

The aim of the study is to determine whether there is a correlation between changes in the renal resistive index and the restoration of kidney function in critically ill patients undergoing continuous renal replacement therapy.

DIAGNOSTIC_TEST

Measurement of Renal Resistive Index

The kidneys are preliminarily visualized in a 2D projection, followed by identifying interlobar or arcuate vessels using color Doppler. Flow measurements in these vessels are performed using pulsed-wave Doppler. Renal Resistive Index is determined over three cardiac cycles (five in the case of atrial fibrillation) in two different arteries, each in a different kidney section. Subsequently, measurements from each artery are averaged. If possible, the examination should be conducted bilaterally. The investigators do not have access to previous measurements (each study is recorded on a separate card).
