Abstract
OBJECTIVE: To assess the efficacy of the subureteric Teflon injection (STING) procedure in the refluxing duplex ureter. PATIENTS AND METHODS: The STING procedure was performed in 23 patients (five boys and 18 girls, mean age 6.5 years, [range 1.5-14]) with six refluxing upper and 31 refluxing lower moieties. Teflon was injected separately into each moiety of the duplex. All patients were assessed by a micturating cystourethrogram and ultrasonography at least 3 months after treatment and the results were analysed retrospectively for the success rate of each refluxing unit and the overall cure rate of patients. RESULTS: No patient suffered ureteric obstruction. After the first STING the unit cure rate was 57% but only nine of 23 patients were completely cured. This improved to a unit cure rate of 68% and 11 patients cured after a second STING. CONCLUSION: Because the patient cure rate was poor we do not advocate using the STING to treat vesicoureteric reflux in the duplex kidney.
