Vesicoureteral reflux in children: endoscopic treatment.
Endoscopic correction of vesicoureteral reflux in children has been increasingly used in the last years with encouraging results. During a 4-year period 152 children were treated by endoscopic injection of Teflon. A follow-up, ranging from 3 months to 5 years, was available for 173 refluxing ureters. For primary reflux, correction was observed after a single injection in 87% of the cases and in 93% after a second injection in some failures. In duplication, the technique is somewhat more difficult but the results quite satisfactory with 58% success after one injection, increasing to 74% after a second injection. The limitations of these techniques are underlined, the major concern being the safety of the injectable Teflon particles, eliciting a foreign-body granulomatous reaction with the potential hazard of distant migration. So far no long-term morbidity and complications have been observed with the use of Teflon to correct reflux. Extensive pathological study in 7 children submitted to ureteral reimplantation for failure of endoscopic correction showed a typical encapsulated granulomatous reaction below the intramural ureter, but particles of Teflon were noted in only one hypogastric ganglion when the Teflon was injected outside of the bladder. There is a need for finding an ideal substance for endoscopic injection, preferably prepared from the patient's own tissue allowing simple and safe correction of vesicoureteral reflux in children.
