Can you mention what types of postoperative changes are seen?
Anterior displacement of the kidney, upper posterior renal cortical defect, perinephric fat stranding and a postoperative fluid collection seen.
Is there another finding that may alter the staging?
Yes, a left lower pulmonary nodule that may be metastatic.
There is a 5 x 6 x 5 cm postoperative fluid collection with peripheral enhancement seen posterior to the right kidney. This was aspirated under ultrasonographic guidance, culture and sensitivity tests were done and appropriate antibiotics were given.
A 1.5 cm left lower lobe lung nodule is newly developed.
