Risk factors for kidney damage in pediatric patients with recurrent urinary tract infections

Abstract

was a retrospective, cohort study of patients <10 years with ITUR, who consulted as outpatients at the Social Security Institute Hospital and private clinics from January 2015 to July 2017. For our statistical analysis, patients were categorized in two groups according to whether or not they presented kidney damage. The correlation between kidney damage and age, sex, number of urinary tract infection episodes and the presence of vesicoureteral reflux (VUR) was established. For each variable, the relative risk (RR) with a confidence interval of 95% was calculated using Microsoft Excel 2010. Results: 112 patients presented ITUR, the average age was 41.8 months (SD: ± 38.1), M / F ratio: 1: 6. The average number of episodes of UTI per patient was 3.5 (SD ± 1.9). 82/112 (73.2%) had sphincter control and 30/112 (26.7%) did not. Constipation, urinary urgency, incontinence, urinary retention were reported concomitantly in 38%, 48%, 33% and 20% of patients, respectively. The pathologies associated with ITUR were: lower urinary tract dysfunction in 45.5%, vesicoureteral reflux in 37% and hypercalciuria in 16.7%. The sensitivity and specificity of ultrasound to diagnose VUR were 22.7% and 87% respectively. 27/112 (24%) presented kidney damage. The factors associated with kidney damage were age <12 months (p = 0.027, OR 1.2-9, RR 2.2 (95% CI 1.1-4)),> 2 episodes of UTI (p = 0.0005 , OR 1.9-12, RR 3.2 (IC95% 1.6-

Factores de riesgo asociados a las infecciones urinarias en pacientes pediátricos atendidos en el centro de salud de Santiago 2020-2021

“…3 El estudio de Troche en Paraguay en el 2018 demuestra que los episodios a repetición están asociadas a las infecciones urinarias en menores de 10 años. 5 También es encontrada en el estudio de Hinojosa en Lima donde el 33% de los pacientes tuvo como antecedente de infecciones urinarias recurrentes. 8 Álvarez encuentra un riesgo de hasta 3,4 veces más de tener infección urinaria en los niños que tiene infecciones urinarias recurrente.…”
