Purpose: We wanted to determine the correlation between the renal length as
measured on two dimensional (2D) ultrasonography (US) and the renal parenchymal
volume as measured with a new three-dimensional (3D) volume probe ultrasound
system. We also wanted to determine the correlation between the renal length or
renal parenchymal volume and the glomerular filtration rate (GFR) in patients with
glomerulopathy.
Materials and Methods: From July 2007 to December 2007, 26 patients who were
pathologically confirmed to have glomerulopathy by biopsy were enrolled. Renal
length was measured with 2D US and the renal parenchymal volume was measured
with 3D US just prior to biopsy. The GFR was obtained from the electronic medical
records. Pearson’s correlation coefficients were used to analyze the correlation
between the renal length and the renal parenchymal volume, the correlation between
the renal length and the GFR and the correlation between the renal parenchymal volume
and the GFR.
Results: The renal length and the renal parenchymal volume showed strong positive
correlation (r = 0.850, p = 0.0001). The correlation coefficient between the renal
length and the GFR was 0.623 (p = 0.0007) and the correlation coefficient between
the renal volume and the GFR was 0.590 (p = 0.0015). Both the renal length and
renal parenchymal volume showed apparently positive correlations with the GFR in
glomerulopathy patients.
Conclusion: The renal length showed strong positive correlations with the renal
parenchymal volume. Both the renal length and the renal parenchymal volume
showed apparently positive correlations with the GFR in glomerulopathy patients. In
glomerulopathy patients, the renal dimensions measured by ultrasound can reflect the
status of the GFR, and the measurement of the 2D renal length could be sufficient for
follow up. Further studies are needed to evaluate the role of 3D US for assessing
patients with renal disease. |
