Vesicoureteric reflux - treatment?

I suffered from reflux causing kidney infections as a child. They treated it by injecting some substance into certain valves. I have started to get infections again. Do you have information of what it is that they might have done?

It sounds to me as if you went through a procedure known as a STING (submucosal Teflon injection). The procedure is performed to control vesicoureteric reflux, which means controlling the back flow of urine from the bladder up into the ureter. This back flow can give rise to recurrent urinary tract infections. Vesicoureteric reflux is a common cause of recurrent urinary tract infections and the STING procedure has been performed on many children to control this problem. This procedure is performed under a general anaesthetic and involves the injection of a small volume of Teflon into the wall of the bladder just at the point where the ureter enters the bladder. If necessary the procedure can be performed at the entrance of both ureters (one from each kidney). The injection is performed with an endoscope, which is passed into the bladder through the urethra, which enables the doctor to inject the Teflon without needing to open the abdomen. The injected Teflon creates a small lump in the wall of the bladder just where the ureter enters. This small lump in the wall of the bladder helps to prevent back flow of urine up through the ureter and into the kidney. If reflux were not controlled it could give rise to frequent infection, which in turn could cause scarring of the kidneys.
