[Vesicoureteral reflux: diagnosis and management in children].
OBJECTIVE
Based on a retrospective study of children followed for vesicoureteric reflux, the authors evaluated the role of antenatal diagnosis in the detection and global management of the most frequent uropathy observed in children.


METHODS
The case files of 180 children followed for reflux over a 4-year period were reviewed. The diagnosis of reflux was based on retrograde cystography. The authors tried to define the main indications for the renal and urinary tract assessment and defined the grade and type of reflux, as well as the therapeutic indications and results. 180 children (105 girls and 75 boys) with vesicoureteric reflux were observed during the study period. The mean age at the time of diagnosis was 26.75 months.


RESULTS
Vesicoureteric reflux was usually diagnosed in a context of acute pyelonephritis in 139 children (77%);, at the time of the first episode in 84% of cases. Antenatal diagnosis of reflux during screening for dilated renal pelvis was the second most frequent modality (29 children, 16% of cases). The reflux involved a single urinary tract in 163 children and a duplicated tract in 17 children. Reflux was bilateral in 43% of cases. Reflux was less than grade II in 66% of cases, but an inverse proportion was observed in the case of antenatal diagnosis (62%). 55% of cases were treated surgically and 45% were treated medically. Follow-up of the children showed a low recurrent pyelonephritis rate that was similar in the two groups.


CONCLUSIONS
Acute pyelonephritis remains the leading mode of discovery of vesicoureteric reflux and renal ultrasonography combined with retrograde cystography after a first episode of renal infection is therefore recommended. Antenatal screening may also reveal vesicoureteric reflux. It is difficult to summarize the therapeutic indications for reflux, as the treatment of vesicoureteric reflux is related to the child's age and sex, the grade of reflux, the clinical repercussions of the reflux and certain environmental factors, such as the family and social status.
