To correlate between renal length on 2D USG and renal volume measured using a new 3D volume probe ultrasound system and to correlate between renal volume and glomerular filtration rate(GFR) in glomeurolnephritis patients.

From July 20, 2007 to December 13, 2008, renal length was measured with 2D ultrasonography for consecutive 35 patients who underwent kidney biopsy to confirm renal parenchymal disease. Out of them, 26 patients were confirmed to have glomerulonephritis. At the same day, just before renal biopsy, three-dimensional US was performed using 3D volume probe. Total renal volume(A) and the volume of sinus fat(B) were measured. Renal parenchymal volume was calculated by subtraction(A-B). GFR within 2 days before ultrasonographic examination and renal biopsy was obtained from electronic medical record. The Pearcon correlation was analyzed for evaluating the correlation between the renal length and 3D volume. The correlation of GFR with renal volume was also evaluated.

The correlation coefficients between renal length and renal parenchymal volume of both kidney were 0.814 (left, p<0.0001) and 0.749 (right, p=0.0001), respectively. The both renal volume showed statistically significant correlation with GFR in glomeurlonephritis patients (r=0.459(p=0.018) for right kidney and r=0.647(p=0.004) for left kidney).

Renal length obtained from 2D ultrasonography showed good correlation with renal parechymal volume. Renal parenchymal volume obtained from 3D ultrasonography can represent renal function in the patients who has glomerulonephritis .

3D volume prove ultrasound system could be useful to evaluate renal fuction in the patients with glomerulonephritis.
