[Intermittent ureteropelvic junction obstruction and aberrant vessel to the lower pole of the kidney in children]. / Obstruction intermittente de la jonction pyélo-urétérale et vaisseaux polaires inférieurs chez l'enfant.

ABSTRACT

Intermittent ureteropelvic junction obstruction in children is a distinct clinical syndrome, it is often associated with an anteriorly crossing aberrant vessel to the lower pole of the kidney. The presence of these vessels increases the risk of complication and requires surgical management. CT scan is already the best exam to find these vessels in adults before treatment. It seems to be also efficient in children. This case report illustrates this indication.
