Prevalencia de insuficiencia renal crónica en niños con displasia renal multiquística, Fundación Cardioinfantil de Bogotá

Abstract

Introduction: Multicystic renal dysplasia is a variant of renal dysplasia, common congenital anomaly of the urinary tract, with a prevalence of 2.9 - 50% of chronic renal failure, increased urinary associated with other malformations, no data on prevalence in bogotá or clinical behavior. Objective: To evaluate the prevalence of chronic renal failure in children with multicystic dysplastic kidney nephrology consultation valued at Fundación Cardioinfantil instituto de cardiologia of Bogota. Methods: Cross-sectional study in children with multicystic renal dysplasia, confirmed by ultrasound of Pediatric Nephrology consultation in the last ten years. We performed a descriptive analysis of the variables, prevalence estimates of chronic renal failure Results: We reviewed data from 70 patients and found a prevalence of CKD of 22.85% (CI95% 13.0% - 35.1%), more often women 12.85%, 14.28% in patients with other renal malformations; 5.71% in partial involution, 4.28 % in complete regression of renal size. Proteinuria was found 31.4%, 22.8% hyperfiltration, 4.28% healthy kidney compensatory hypertrophy, partial involution 24.2%, 31.4% complete regression of renal size, frequency of hypertension of 7.1% (95% 1% -9%). The prenatal diagnosis was 87.14% (95% CI 81.0% -96.0%). Discussion: The prevalence is within the ranks of world literature, higher than Colombia and south America, predominantly in patients with other renal malformations associated with higher prevalence of hypertension, requiring multicenter studies to determine causality or presence of other factors.
