Abstrakt: Objective: The aim of our study is to compare long-term outcome of endoscopic treatment of VUR using PPC or Dx/HA. Patients and methods: From October 2014 to April 2017 patients with VUR grades from 3 to 5 that needed endoscopic treatment were eligible for this RCT. Patients were randomized in two groups: PPC and Dx/HA. A VCUG was performed at 6 months; if VUR > 3 was still present a second ET was performed. We included for this long-term follow-up study those patients that were successfully treated at short-term follow-up. At 36 months postoperative VCUG was performed to assess outcome. Success was considered if postoperative VUR grade was 0 at 36 months, and there was no ureteral obstruction. Results: In the previous study, 60/73 ureters were successfully treated in 36/44 patients, and then we have analyzed 60 ureters in 36 patients. Three patients were lost in long-term follow-up, and then we analyzed 57 ureters in 33 patients divided. PPC group 18 patients (28 ureters); and Dx/HA group 15 patients (29 ureters). After 3 years of follow-up the VCUG showed a success rate of 26/28 of RU in PPC and 26/29 of DX/HA. Two RU in PPC group had ureteral obstruction, and then the successful rate for PPC group dropped to 24/28. The overall successful rate at long-term was 72.7% of the RU in PPC group and 70.3% in Dx/HA group. Conclusion: PPC and Dx/HA has similar long-term outcome in VUR resolution, but ureteral obstruction could be present at long-term follow-up in PPC group. [ABSTRACT FROM AUTHOR]
