title: Aberrant renal vessel causing hydronephrosis in crossed-fused ipsilateral ectopic kidney: a rare case report.
abstract: A crossed-fused ectopic kidney is a rare congenital anomaly, and uncommonly we see an aberrant vessel as a cause of hydronephrosis in a kidney. We report a case of 4-year-old boy with crossed-fused right renal ectopia with hydronephrosis in the both kidneys. The aberrant renal vessel was found pressing the left pelvi-ureteric junction causing hydronephrosis. Dismembered pyeloplasty of the left kidney was performed anterior to the aberrant vessel. The patient is doing well in the follow-up visits and his renal function is stabilized. Aberrant blood supply may be a cause of hydronephrosis in the crossed-fused ectopic ipsilateral kidney. Keeping this entity in differential diagnosis will help in successful management of the crossed-fused ectopic kidney.
