Objective: To evaluate the safety and efficacy of endoscopic treatment of vesicoureteric reflux in children persisting after surgical reimplantation.
Material and methods: 12 children between the ages of 17 and 103 months were treated by endoscopic injection after failure of Cohen ureterovesical reimplantation. An associated uropathy was present in 4 children. Reflux was unilateral in every case. The operation was performed as a day-only procedure. All children were reviewed at 3 months.
Results: No early complications were observed. The follow-up cystography was normal in 10 children. The same degree of reflux persisted in 2 children, requiring a second ureterovesical reimplantation. A meatal stricture occurred 2 years after injection. The mean follow-up was 24.7 months. The success rate of the technique was 75% in this series.
Conclusion: This technique is reliable, simple and can be performed in the day hospital. However, these good results must not mask the risk of long-term recurrence, requiring prolonged surveillance.
