Se realizó un estudio descriptivo longitudinal en pacientes con diagnóstico de reflujo vesicoureteral, que fueron atendidos en consulta de Nefrología pediátrica durante un período de cinco años, con el objetivo de identificar: las manifestaciones clínicas iniciales, los factores asociados y las alteraciones en estudios de imagen. El síntoma inicial fundamental fue la recurrencia de infecciones urinarias febriles (82,3 %). Se encontraron varios factores de riesgo asociados: el antecedente familiar de malformaciones renales (57,32 %), la diabetes materna (38,45 %), el hábito de fumar (24,67 %) y la anemia (18,20 %). Se observaron alteraciones sonográficas (60 %); predominaron el reflujo vesicoureteral grado 3 y la presencia de cicatrices renales. Las alteraciones sonográficas son frecuentes en estos pacientes, si bien su normalidad no lo descarta. La nefropatía cicatrizal se asocia al reflujo vesicoureteral, sobre todo asociado a infecciones urinarias febriles.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT Vesicoureteral reflux is a frequent cause of chronic kidney damage and the need for renal replacement therapy. A longitudinal descriptive study was carried out in patients who were diagnosed with vesicoureteral reflux and seen in the Pediatric Nephrology consultation for a period of five years, with the aim of identifying early clinical manifestations, associated factors and alterations in imaging studies. Recurrence of febrile urinary tract infections was the main initial symptom (82.3%). Several associated risk factors such as family history of kidney malformations (57.32%), maternal diabetes (38.45%), smoking habit (24.67%) and anemia (18.20%) were found. Sonographic alterations (60%) were observed; presence of grade III vesicoureteral reflux and renal scarring predominated. Sonographic alterations are frequent in these patients, although its normality does not rule it out. Scarring nephropathy is associated with vesicoureteral reflux, especially with febrile urinary tract infections.]]></p></abstract>
