A Rare Case of Nephroureterectomy of Crossed Fused Renal Ectopia with Urothelial Carcinoma

Dr. Rupam Deori | Dr. Renu Thomas


Abstract: Introduction: Crossed fused renal ectopia (CFRE) is a congenital anomaly, where one of the kidneys crosses the midline and located at the other side. Urothelial carcinoma in CFRE is an exceedingly rare clinical finding. Case Report: A 57 years old male who presented with pain abdomen and on evaluation, he was diagnosed with CFRE with tumour and stones in CT Scan. PET CT Scan showed crossed fused renal ectopia on the right side in the right iliac fossa with multiple calculi in fused left kidney. Metabolically active lesion in extrarenal pelvis of fused left kidney likely ?TCC. Metabolically active enlarged para-aortic, aortocaval and left iliac nodes with stage pT3,N2,Mx. The chosen treatment was nephrectomy of the left moiety with ureterectomy, bladder cuff excision and lymph node dissection. The final pathology revealed urothelial carcinoma with squamous differentiation, involving pelvicalyceal system and ureter, infiltrating into the sinus fat. Para-aortocaval and left common iliac lymph nodes showed metastasis. Conclusion: Our case highlights that nephroureterctomy with preservation of normal functioning moiety seems to be excellent option for urothelial carcinoma in a CFRE .
