A Case Report on Rare Congenital Anomaly: Crossed Fused Renal Ectopia

Abstract

Congenital anomalies of the kidney and urinary tract are relatively rare and can present with a wide range of clinical manifestations, making diagnosis and management challenging. A rare developmental anomaly of urinary system L-shaped kidney with bilateral Double pelvis and bifid ureter located anterosuperior to the bifurcation of abdominal Aorta at the level of L4. Resulted as a consequence of abnormal renal ascent in embryogenesis due to migration and fusion of left kidney to the lower pole of the right kidney. Surgeons must remain vigilant for potential complications, including infections, obstructive issues leading to stone formation, and concurrent malformations in other organs that may increase the risk of malignancy. Additionally, ectopically located kidneys are prone to injury during pelvic surgeries, particularly those involving the aorta, due to their anomalous blood supply originating from the abdominal aorta, and environmental factors, such as other nutrients and hormones.
