This study confirms the accuracy and reliability of sonographic assessment
of renal dimensions when meticulous scanning techniques are employed.
Sonographic renal dimensions are smaller than those obtained by
radiography, since there is neither the geometric magnification nor the
change in size related to an osmotic diuresis from iodinated contrast
material. Sonographically, with patients in the prone position, the mean
right renal length was 10.74 cm (+/- 1.35 SD) and the mean left renal
length was 11.10 cm (+/- 1.15 SD). A prospective sample demonstrated the
mean depth (ventral-dorsal dimension) to be approximately 4.5 cm when the
transducer was angulated for the lie of the kidney.
