Introduction:

 We aimed to evaluate the clinical and radiological course of children with persistent or resolved hydronephrosis associated with vesicoureteral reflux (VUR).

Material and methods:

 Hospital files of children with primary VUR and collecting system dilatation were retrospectively evaluated. Those with a follow up period >12 months were enrolled. Children were grouped as those with resolution of collecting system dilatation by ultrasonography (Group 1) and with persistent dilatation (Group 2). Both groups were compared for age, gender, follow up period, VUR grade, presence of renal scar, new development of renal scar and urinary tract infection (UTI) recurrence.

Results:

 51 patients were enrolled in the study. Group 1 (n=32) and Group 2 (n=19) were not different with respect to age (45.2±49.5 vs 39.4±44.3 months), gender (F/M=16/16 vs 9/10), ≥grade 3 VUR (11/32 vs 10/19), presence of renal scar (20/32 vs 12/19), folow up peiod (51.2±30.9 vs 50.6±31.6 months), breakthrough UTI rate (10/32 vs 5/19) and new scar formation (8/32 vs 4/19).

Conclusions:

 Resolution of collecting system dilatation by ultrasonography does not eliminate the risk of new UTI and scar formation in children with VUR.
