Objetivo: Investigar los resultados de la inyección endoscópica y comparar la eficacia de dos agentes de carga diferentes tanto como el Macroplastique y Vantris.  Métodos: Los datos de los pacientes que se sometieron a inyección endoscópica para el tratamiento del reflujo vesicoureteral en el Hospital Nacional de Niños entre diciembre 2011 y Febrero 2015 fueron retrospectivamente revisados. Se excluyeron pacientes con disfunción miccional persistente, que no tuvieran cistouretrografía miccional posterior al tratamiento endoscópico y expedientes incompletos. La técnica quirúrgica utilizada fue la de STING clásica. El control postoperatorio fue a los 3 meses y se realizó ecografía de vías urinarias; la profilaxis antibiótica se continuó hasta la cistouretrografía miccional control. El éxito del tratamiento se define como la desaparición de reflujo en el cistouretrografía miccional de control.  Resultados: En total se revisaron 38 casos, de los cuales 33 cumplían con los criterios de inclusión, el 66,6% correspondía a niñas y el 33,3% a niños; se documentó un 42,4% con reflujo vesicoureteral bilateral (14 casos), luego sigue el lado izquierdo con un 36,36% (12 casos) y el lado derecho con un 21,21% (7 casos). En total se evaluaron 47 unidades ureterales. El Vantris se utilizó en el 63,6% de los casos y el Macroplastique en el 27,4%. La mayoría de los pacientes presentó resolución de su reflujo vesicoureteral posterior al tratamiento (29 casos: 88%); una menor cantidad, persistencia del reflujo (4 casos: 12%), y de estos, 4 pacientes persistieron con reflujo vesicoureteral de menor grado que al momento del diagnóstico. Todos se volvieron a someter a inyección endoscópica antirreflujo, de ellos 3 se curaron y uno persistió con reflujo vesicoureteral, pero de bajo grado y asintomático, por lo que se está manejando de manera conservadora.  Conclusiones: La corrección del reflujo vesicoureteral por inyección endoscópica con Macroplastique y Vantris es segura, efectiva y mínimamente invasiva.]]></p></abstract>

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.]]></p></abstract>
