Durability of antireflux effect of ureteral reimplantation for primary vesicoureteral reflux

Wednesday, 18 January 2012-  K. Hubert and colleagues conducted a study to evaluate the long-term durability of successful ureteral reimplantation (UR) for vesicoureteral reflux (VUR) through a review of late cystography (LC) findings. They published their findings in an online edition of Urology.

The researchers performed a retrospective chart review of all children with primary VUR who underwent successful open UR (grade 0 VUR into the reimplanted ureter[s] on initial cystogram) at our institution from January 1990 to December 2002. They identified successful UR patients who underwent LC ≥1 year after UR and reviewed the results for the presence of recurrent VUR into the reimplanted ureter(s).

Seven-hundred ninety-four patients underwent successful open UR for primary VUR, of whom 60 (7.6%) had a subsequent LC. Preoperative VUR grade was ≤II in 20 (34.5%) and ≥III in 38 (65.5%). Median age at UR was 3.5 years (IQR 1.3–6.2 years); 51 (85%) were female. UR was intravesical in 45 (75%) and bilateral in 19 (32%). LC was performed at a median of 38.7 months after UR (IQR 19.6–66.1 months). 

Indication for LC was febrile urinary tract infection (UTI) in 16 (27%), nonfebrile UTIs in 15 (25%), follow-up of contralateral VUR in 16 (27%), and other clinical indications in 13 (21%). The recurrence rate was 0%; of the 79 reimplanted ureters, 100% (95% CI 95.4–100) had no VUR (grade 0).

“Among children who underwent successful open UR for primary VUR, there was no VUR recurrence on extended follow-up. This suggests that the late durability of open antireflux surgery is excellent,” the authors concluded.
