ABSTRACT
El refujo vesicoureteral (RVU) es el fujo de orina desde la vejiga hasta el tracto urinario superior. Está presente en el 25% al 70% de los niños con infección urinaria asociada a pielonefritis. Se realizó una revisión de la bibliografía sobre el tratamiento endoscópico del RVU analizando las técnicas, los materiales utilizados, las indicaciones y las complicaciones descritas. De los artículos encontrados, se seleccionaron los más recientes y las Guías Europeas y Norteamericanas. El tratamiento endoscópico del refujo, que se ha impuesto progresivamente como técnica de elección para el tratamiento primario del RVU asociado a pielonefritis o a infecciones, permite retrasar el recurso a la cirugía.
Introduction. Vesico-ureteral refux (VUR) is defned as the retrograde fow of urine from the bladder to the upper urinary tract and is distinguished in primary and secondary. It is present in 25-70% of children who have a urinary tract infection (UTI) associated with pyelonephritis, the association between UTI and VUR predisposes children to have renal scarring with consequent alteration of the functionality until chronic renal failure. Material and methods. We realized a review of the literature on the endoscopic treatment of vesico-ureteral refux analyzing the different techniques, materials used for endoscopic injection, indications and complications described in the literature. Results. Over 100 articles we found on the endoscopic treatment of refux with indications, complications and outcomes in the short, medium and long term. Of these we selected the most recent and current European and American Guidelines. Conclusions. Endoscopic treatment of refux has become gradually the technique of choice for the primary treatment of vesico-ureteral refux associated with pyelonephritis or urinary tract infections and permits to delay the use of open surgery.
