Abstract:
The combination of reflux and infection may produce progressive renal damage. If the V-U reflux is corrected, normal renal growth can be resumed in most cases, but some cases remain with reduced renal growth. 70 kidneys with V-U reflux during the past 5 years was reviewed clinically, so the following results were obtained; 1. The incidence of renal scar was noticed in 50% among 70 VUR cases, and the incidence and the severity of renal scar was increased according to the grade of VUR. 2. 33 cases (94.3%) of 35 cases with renal scar was associated with UTI, and in these cases the grade of renal scar was higher than no UTI cases. 3. Under the age of 4 years the incidence of renal scar was high as 23 (60.5%) out of 38 VUR cases. and over the age of 4 years the incidence of renal scar was low as 12 (37.5%) out of 32 VUR cases. 4. The length & width in VUR cases compared to normal for age was within normal limit, but the renal parenchymal thickness compared to normal was lower. In the higher grade of VUR the parenchymal thickness was thinner than in he lower grade. 5. In most cases of successfully treated VUR medically and surgically, renal parenchymal thickness was grown into the normal level. Although the VUR was treated successfully, renal parenchymal growth was retarded in the higher grade of VUR (more then IV) or more severe renal scar (more than b).
