Lump type crossed fused renal ectopia with bilateral vesicoureteral reflux: A case report

BACKGROUND: 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. 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.
