Introduction:

Endoscopic suburetal injection, is the less invasive method with promising results for the treatment vesicoureteral reflux.

Objective:

To investigate the results of endoscopic injection and compare the efficacy of two agents of different load such as Macroplastique and Vantris.

Methods:

Data of patients that underwent endoscopic injection for vesicoureteral reflux treatment at Hospital Nacional de Niños between December 2011 and February 2015 were revised retrospectively. Patients with persistent voiding dysfunction, that had no micturatingcystourethrogram after the endoscopic treatment and incomplete records were excluded. The surgical technique used was STING Classic. The postopertative control was after 3 months and an urinary tract ultrasonography was done, a continuous antibiotic prophylaxis was performed until the control voiding cystourethrogram. Treatment success is defined as the disappearance of reflux in the control voiding cystourethrogram control.

Results:

A total of 38 cases were reviewed, of which 33 met the inclusion criteria, 66.6% were girls and 33.3% were boys, 42.4% were documented with bilateral vesicoureteral reflux (14 Cases), following 36.36% (12 cases) on the left side and on the right side 21.21% (7 cases). In total 47 ureteral units were evaluated. The Vantris was used in 63.6% of cases and Macroplastique in 27.4%. The majority of patients showed resolution of their subsequent vesicoureteral reflux after the treatment (29 cases: 88%), a smaller amount with persistent reflux (4 cases: 12%) of these, 4 patients persisted with vesicoureteral reflux in a lesser degree than at the moment of the diagnosis, all were submited the endoscopic antireflux injection again, of which 3 were cured and one persisted with vesicoureteral reflux, but of low grade and asymptomatic, being managed conservatively.

Conclusions:

Correction of vesicoureteral reflux by endoscopic injection with Macroplastique and Vantris is safe, effective and minimally invasive.
