摘要
Crossed renal ectopia is the second most common fusion anomaly of the kidney after horseshoe kidney. The incidence of both fused and unfused cases is 1 in 7000 in autopsies. The unfused crossed renal ectopia is much rare with an incidence of 1/75000 in autopsies. Ninety percent ofectopic kidneys are fused to their ipsilateral mate and the ureter of the ectopic kidney inserts into its normal position in the bladder at the contralateral side. But demonstration of the anomaly may provide to search for accompanying congenital anomalies and to plan a follow-up program for possible future complications in most of the cases. However it may remain asymptomatic for years as in the patients. Here the authors are presenting a 64-year-old male patient, with a right sided unfused crossed renal ectopia anomaly without any complaints until this age.
