Renal U/S



STEPS
Right Kidney:
  • Same starting point as in the FAST exam for RUQ
  • Draw an imaginary perpendicular line down from xiphisternum to the right mid-axillary line
  • Ultrasound probe held in a horizontal, coronal plane, or with a slight tilt (remember that the normal lie of the kidney has the superior pole more posterior and the inferior pole more anterior)
  • Scan through the right kidney in longitudinal view with a fanning motion, making sure both superior and inferior poles are well visualized
  • Rotate the probe 90 degree clockwise and scan the kidneys in a transverse plane from superior to inferior pole
Left Kidney:
  • Same starting point as in the FAST exam for RUQ
  • Draw an imaginary perpendicular line from the xiphisternum to the left posterior axillary line
  • Ultrasound probe held in a horizontal, coronal plane or with a slight tilt.
  • Scan through the right kidney in longitudinal view with a fanning motion, making sure both superior and inferior poles are well visualized
  • Rotate the probe 90 degree clockwise and scan the kidneys in a transverse plane from superior to inferior pole
