PURPOSE: Endoscopic injection of stabilized nonanimal hyaluronic acid/dextranomer gel is an established treatment for vesicoureteral reflux in children. We performed a subgroup analysis to assess this treatment in reflux associated with bladder dysfunction.
MATERIALS AND METHODS: Of 308 consecutive children treated endoscopically with stabilized nonanimal hyaluronic acid/dextranomer gel for dilating vesicoureteral reflux 54 were observed retrospectively to have bladder dysfunction. Initial followup consisted of voiding cystourethrogram at 3 and 12 months after injection, with positive response defined as reflux grade 0 or I. At 7 to 12 years following treatment patient charts were checked for urinary tract infections and bladder dysfunction, and a followup survey (postal questionnaire) was administered.
RESULTS: A positive response to therapy (cure) was observed in 45 children (83%) after 1 to 3 endoscopic treatments. Concurrently, bladder dysfunction had resolved in 32 patients (59%). After the last stabilized nonanimal hyaluronic acid/dextranomer gel implantation 45 patients (83%) were free of urinary tract infections. Questionnaire results were similar to chart based findings. Stabilized nonanimal hyaluronic acid/dextranomer gel implantation was well tolerated, with no associated complications.
CONCLUSIONS: Endoscopic treatment with stabilized nonanimal hyaluronic acid/dextranomer gel appears to be similarly effective in patients with vesicoureteral reflux with and without bladder dysfunction. These data indicate that bladder dysfunction should not be considered a contraindication to endoscopic treatment for reflux.
