Cross ectopic multicystic dysplastic kidney with ureterocele in nonectopic site.

Crossed renal ectopy (CRE) is the second most common fusion anomaly of the kidney, with an incidence of 1 in 7000 autopsies; it comes in second after horseshoe kidney. Crossed renal ectopy is associated with an ectopic ureter and generally an ectopic kidney fused with a normal kidney. A 7-month-old boy who had left-to-right crossed non-fused renal ectopy and multicystic renal dysplasia with ureterocele in nonectopic kidney was reported in English language literature. In this article, we present the first case of CRE where surgical intervention has been performed.
