Crossed fused renal ectopia is a rare congenital anomaly of the ascent of the kidney. 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.
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.
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.
Core tip: Crossed fused renal ectopia is a rare congenital anomaly in pediatric urology. The majority of the cases shows a favorable prognosis with conservative management, while early surgical intervention should be considered in selective cases. Up to now, the guideline for the disease has not established, and this case may be beneficial to determine therapeutic plan, especially for the necessity of surgery. Furthermore, the helpful diagnostic and therapeutic methods are mentioned based on our experience.
