Abstract:
BACKGROUND:There are many controversies surrounding the effectiveness of endoscopic treatment of vesicouretheral reflux (VUR) in children, thus it is of highest priority to analyze factors influencing the outcome of therapy and to search for new methods that would increase the success rate and reduce the number of reinjections. OBJECTIVE:The aim of the study was to analyze whether intraoperative contrast-enhanced urosonography (ce-US) may increase the effectiveness of endoscopic anti-reflux therapy. MATERIALS AND METHODS:Intraoperative contrast-enhanced urosonography (ce-US) with SonoVue® was performed in 17 patients (25 ureteral units) undergoing endoscopic treatment of VUR. Ce-US was performed in the operating room before the procedure and after injection of the bulking material. When VUR persisted, the operator repeated the injection, which was followed by ce-US. The results were compared with those obtained from a control group (15 patients; 22 ureteral units). RESULTS:A repeat injection during a single endoscopic treatment was required in 24% of cases. The overall success rate confirmed at 6-12 months' follow-ups was 84%. The success rate was significantly higher in comparison to the control group (success: 64%). CONCLUSION:Intraoperative ce-US performed during endoscopic treatment of VUR enables immediate monitoring of outcome and provides the opportunity for repeat injection during the same procedure, thus increasing the efficacy of the procedure and reducing the number of reinjections.

Though most of the lesions present in infants and young children with a typical appearance, it is important to understand that they all do not behave in the same way.
