Renal resistive index measurements by ultrasound in patients with liver cirrhosis: Magnitude and associations with renal dysfunction

Figure 1 Measurements of the renal resistive index. A and B: Using a duplex Doppler ultrasound machine at right renal artery at hilum (A) and right lower interlobar artery (B).

Figure 2 Selection of study participants. A total of 557 hospitalized cirrhosis patients were evaluated during study period. On the basis of various exclusion criteria, 357 patients were excluded. Finally, 200 cirrhosis patients were found eligible for the inclusion. AKI: Acute kidney injury; ATN: Acute tubular necrosis; HRS: Hepatorenal syndrome; ICU: Intensive care unit; PRA: Pre-renal AKI; RRT: Renal replacement therapy; USG: Ultrasound.
