POCUS evaluation in acute kidney injury. . Image A. With the patient supine, place a low-frequency probe (probe marker pointing cephalad) at the mid-axillary line (dotted line) just above the costal margin, with the ultrasound beam directed into retroperitoneal space. The longitudinal l view of the kidney should be in view. The probe should then be rotated clockwise 90 degrees to obtain the transverse view (image not shown). Image B. Representative image of normal right kidney in the longitudinal view with structures labeled. Note the normal kidney architecture with the non-dilated kidney pelvis and preserved kidney parenchyma (cortex, pyramids). Image C. Representative image of hydronephrosis of the right kidney in the longitudinal view with structures labeled. Note the abnormality within the urinary collecting system including the central dilation of the kidney pelvis (anechoic) and calices which appear anechoic within the hypoechoic narrowed kidney cortex.

The admitting resident team performed POCUS evaluation of the kidneys and found an anechoic collection bilaterally within the kidney sinus along with dilated calyces (Figure 1).
