Crossed fused renal ectopia: a rare congenital malformation

Abstract

Crossed fused renal ectopia is a rare congenital malformation, in which the two kidneys are on the same side with one of the ureters and fusion between the two parenchyma. The ureter of the ectopic kidney crosses the midline and implants normally in the bladder. This anomaly is most often asymptomatic and of incidental discovery. We report the case of a patient without similar cases in his family, presenting a crossed fused renal ectopia discovered fortuitously during a prostate hypertrophy assessment.
