PURPOSE: The aim of this study was to review the experience of a single institution with the Deflux (Q-Med Scandinavia; Uppsala, Sweden) procedure and assess its effectiveness in reducing the incidence of urinary tract infections (UTIs) in children with vesicoureteric reflux (VUR). MATERIALS AND METHODS: After institutional review board approval, the charts of 100 patients with VUR, who presented between June 2003 and June 2005, were prospectively reviewed. Data collected included: demographics, the number of preoperative and postoperative UTIs, a radiologic grade of VUR on a voiding cystourethrogram (VCUG) and the presence of VUR on a radionuclide VCUG 3 months after the procedure. Patients were continued on oral antibiotics until urine culture at 3 months was negative and no reflux was demonstrated on VCUG. The student's t test was used for data analysis. RESULTS: The mean age was 3.8 +/- 0.3 years, and 76% were girls. From 155 ureters treated, 10 had Grade I reflux, 42 Grade II, 76 Grade III, 25 Grade IV, and 2 Grade V. A second injection was required in 22 ureters (14.2%). The overall success rate of the procedure (Grade 0 reflux at 3 months) was 77.4% after the first injection and 83.9% after a second injection. The success rate per grade was: 100% for Grade I, 88.1% for Grade II, 86.8% for Grade III, 64% for Grade IV, and 50% for Grade V. The mean follow-up was 446 +/- 20 days. The mean volume injected/ureter was 0.6 +/- 0.03 mL. Thirteen (13) patients had UTIs after the procedure, compared to 75 before. There was a 5-fold reduction in the incidence of UTIs/year, from a mean of 0.68 +/- 0.09 pre- to 0.12 +/- 0.04 postinjection (P = 0.001). The majority of UTIs were caused by Escherichia coli (74% pre- and 82% postinjection). CONCLUSIONS: We conclude that the Deflux procedure is effective not only in eliminating VUR on radiologic studies, but also in reducing the incidence of UTIs and antibiotic use in children with VUR.
