Crossed fused renal ectopia: Challenges in diagnosis and management
A 2-year-old boy, while being investigated with ultrasonography, radionuclide renal dynamic scan and micturating cystourethrography for an abdominal mass, was shown to have an empty right renal fossa. There was crossed fused right renal ectopia with negligible function, a grossly enlarged but normally functioning left kidney and bilateral grade III vesicoureteral reflux. The right renal moiety and ureter was excised and the left ureter was reimplanted by the cross trigonal (Cohen's) technique. He remained well on follow-up.
