Introduction:

 We aimed to evaluate the clinical significance (association with urinary tract infection and renal scar) of severe (grade 4-5) vesicoureteral reflux (VUR) in the absence of renal collecting system dilatation.

Material and methods:

 Hospital files of children with primary grade 4-5 VUR were retrospectively evaluated. Those with a follow up period >12 months were enrolled. Age, gender, presenting complaint, laterality of VUR, presence and grade of hydronephrosis, serum creatinine, proteinuria, hypertension, presence and grade of renal scar by DMSA scintigraphy, need for anti-reflux surgery and follow-up period were recorded. Patients were grouped as those with (Group 1) and (Group 2) without renal pelvis dilatation. Both groups were compared for the variables evaluated.

Results:

 46 patients were enrolled in the study. Group 1 (n=30) and Group 2 (n=16) were not different with respect to presence of renal scar (19/30 vs 11/16) and need for anti-reflux surgery (16/30 vs 9/16). Similary serum creatinine, proteinuria and hypertension freauency were not different between the groups.

Conclusions:

 Presence of severe VUR is associated with renal scar and requires anti-reflux surgery even though collecting system is normal by ultrasonography.
