This anomaly may be observed as a solitary kidney during initial evaluation. A solitary kidney must be evaluated for associated anomalies such as duplication,horseshoe kidney,or crossed renal ectopia.CASE SUMMARY An anomaly was observed in a 9-mo-old male child who was subsequently diagnosed with crossed fused renal ectopia and vesicoureteral reflux(VUR). In this condition,recurrent febrile urinary tract infection can be a serious problem,and can easily cause renal damage due to relatively short ureters and high pressure in the kidney.CONCLUSION To prevent urosepsis and preserve renal function,early diagnosis and proper management including surgical correction should be considered for the management of renal ectopia with VUR.展开更多
