[Prevalence of congenitial kidney and urinary tract anomalies in neonates and infants with congenital heart disease]

Abstract

Introduction: Congenital heart diseases are the most frequent anomalies and one of the most important reasons of mortality and morbidity in neonates and infants. Coincidence of additional malformation aggravates prognosis. The frequency of incidence of other anomalies accompanying congenital hart diseases is defined as 11 to 45%.

Aim: Estimation of the frequency of a coincidence of congenital kidney anomalies on the basis of the ultrasound examination (US) in children with congenital heart disease in first year of life.

Material and methods: Abdominal US were done in 350 neonates and infants hospitalized in Department of Pediatric Cardiology Medical University of Gdansk in the first twenty-four hours after diagnosis of congenital heart disease. Examinations were performed in 187 male (53%) and 163 female (47%) in average age 54.9 days (range from 1 to 349 days).

Results: In examined population congenital kidney anomalies were found in 4.9% of children from which 18% represent hipoplasia, and another 18% dysplasia. 15.3% of examined patients were diagnosed by dilatation of collecting system, whereof 3% mild, 7% moderate, and 5% severe degree.

Conclusions: 1. The frequency of incidence of kidney anomalies and collecting system dilatation in the examined population of neonates and infants with congenital heart disease accounts for 20.2%. 2. Abdominal ultrasound screening with carefully examination of urinary tract should be performed in neonates and infants with congenital heart disease.
