Ultrasound and computed tomographic evaluation of renal transplantation.

Ultrasound and computed tomography are very useful in the diagnosis of parenchymal and urologic abnormalities after renal transplantation. The increased use of Doppler duplex sonography will further enhance the role of ultrasound in the evaluation of patients with kidney transplants. Computed tomography is of particular value in the setting of suspected posttransplant malignancy. Both imaging techniques can be used to guide diagnostic and therapeutic interventional radiologic procedures.
