Both kidneys are identified in lower abdomen — right kidney in right iliac fossa, and left kidney superomedial to it, extending over the midline, sitting in between right & left common iliac arteries.
Both kidneys are fused at their facing surface anterior to the distal part of the right common iliac artery just proximal to its bifurcation.
Long axis of the left kidney is parallel to the vertebral column, with its hilum directed anteriorly and leftwards.
Long axis of the right kidney is parallel to the right psoas major muscle, with its hilum directed anteriorly. A complete cortical band is noted across its mid-polar region, producing two separate collecting systems. Upper moiety pelvis is mildly widened, and unites with the more prominent extrarenal lower moiety pelvis to form a common pelvis. The pelvis has thickened walls with moderate enhancement, as well as internal septations and abrupt narrowing at the pelviureteric junction (PUJ). However, there is no perirenal fat stranding, fluid collection or lymphadenopathy.
Both kidneys excrete contrast promptly and symmetrically.
No dilatation, narrowing or filling defect is seen in either ureter.
