Abstract

To assess the presence and the severity of renal scarring in primary vesicoureteral reflux (VUR), 11 children (3 girls and 8 boys, 19 kidneys) underwent intravenous pyelography (IVP) and 99m Tc-dimercaptosuccinic acid (DMSA) renoscintigraphy and the following results were obtained : 1. Of 19 kidneys, renal margin was shown in 5(26.3% ) and renal scar was revealed only in 3 (15.8%) on IVP. 2. Renal margin in all ( 100.0% ) and renal scar in 12 (63.1%) of the kidney were revealed on 99m Tc-DMSA renoscintigraphy. 3. On the follow-up ranging from 6 months to 13 years after surgical reconstruction, 8 kidneys showed no reversible improvements in renal scar except one, in which progression of renal scar was noted. We concluded that 99m Tc-DMSA renoscintigraphy is more valuable than IVP in evaluating the degree of renal scar and the renal margin.
