Retrocaval ureter: a rare cause of hydronephrosis in children

Retrocaval ureter is a relatively rare developmental anomaly of the inferior vena cava. It commonly manifests in the third to fourth decade of life; however, pediatric reports of this condition are very rare. Individuals with this anomaly are symptomatic because of ureteric obstruction. All symptomatic patients need Surgery where the ureter is divided and anastomosed anterior to inferior vena cava. We report our experience of a child who presented with flank pain and, on evaluation, were found to have right hydronephrosis. During surgery, retrocaval anomaly was noticed and appropriately dealt with. (C) 2009 Elsevier Inc. All rights reserved.
