The underlying renal transplant continues to enhance normally, with preserved corticomedullary differentiation. There is no significant transplant hydronephrosis. Bilateral atrophic native kidneys, with a left-sided baggy extrarenal pelvis and a 14 mm cyst in the interpolar region of the right kidney.
