Endoscopic submucosal Teflon injection (STING): an alternative treatment of vesicoureteric reflux in children.

The authors present their results in treating vesicoureteric reflux with an endoscopic submucosal teflon injection (STING) of the refluxing ureter. One hundred refluxing units in 68 children were treated with a maximum follow-up of five years. Indications were high grade reflux (III-V), persistence or progression of reflux despite conservative therapy, breakthrough urinary infections despite antibiotic prophylaxis and finally bad antibiotic compliance. Treatment was performed on an outpatient basis and appeared to be free of complications. Reflux was cured with a success rate of 75% after a single injection and 96% after two injections. With respect to the grade of reflux, best results were obtained in low grade reflux (Grade I-II). A 60-70% success rate was obtained in high grade reflux (III-V). The main advantage over open reimplantations lies in its non invasiveness, simplicity and possibility of being repeated in case of failure.
