The left kidney is not visualized in its normal anatomical position but is instead crossed over to lie ipsilateral to the right kidney, to which it is fused at its inferior pole. The homogenous density across the two fused renal poles suggests the presence of a parenchymal band joining the two kidneys.
Both kidneys are malrotated, and each has its own renal pelvis.
The ureter of the left ectopic kidney crosses the midline anterior to the right common iliac vessels and enters the bladder on the opposite side. The left vesicoureteric junction appears to be ectopically located, more inferiorly than normal.
The right ureter has a more normal course, lying adjacent to the right psoas muscle. The right VUJ also has a more normal position compared to the left.
There is no calculus nor mass lesion seen within the urinary system and no evidence of hydronephrosis.
The urinary bladder is normal in appearance.
