ULTRASONOGRAPHIC MEASUREMENT OF NORMAL RENAL PARAMETERS

Both kidneys were imaged ultrasono‐graphically in each of 100 normal adult dogs. Small but significant differences were found in the dimensions of the left and right kidneys and in renal dimensions of male and female dogs of similar bodyweight. There was a statistically significant correlation between renal length and bodyweight (r = 0–84, P<0–001). The relationship between renal length and bodyweight was linear except at very low or very high bodyweights. There was also a statistically significant correlation between renal volume and bodyweight (r = 0–91, P<0–001), and the relationship remained linear even at extremes of bodyweight. Graphs could therefore be constructed for renal lengthy bodyweight and renal volume/bodyweight with 95 per cent confidence limits. Copyright © 1990, Wiley Blackwell. All rights reserved
