Delayed Spontaneous Resolution of High Grade Vesicoureteral Reflux After Reimplantation

Significant (grade III/V or greater, International Reflux Study) postoperative vesicoureteral reflux was noted in 4 children who underwent technically satisfactory ureteral reimplantation. All patients had moderate to severe preoperative ureteral dilatation necessitating ureteral tapering in 3 of the 8 ureters reimplanted. Reoperation was considered in all 4 children but a conservative approach was used, with subsequent spontaneous resolution of the reflux 19 to 55 months after reimplantation. We conclude that even high grade reflux after satisfactory reimplantation can resolve spontaneously.
