Single ureter draining crossed fused renal ectopia with single renal vein: case report

Abstract

We present very rare case of incidentally detected crossed fused renal ectopia (CFRE) with a single ureter, single renal vein in a 14-year-old boy who presented as peri umbilical pain and chronic constipation. His contrast enhanced computed tomography (CECT) showed the left kidney was fused to the lower pole of the right kidney with single ureter draining both the moieties into the urinary bladder on ipsilateral side and single renal vein draining into the inferior vena cava. CFRE is usually asymptomatic and undetected in the absence of renal pathologies. Reporting such cases will help in diagnosis and management when symptomatic.
