Owing to the widespread use of CT and ultrasound many patients are often diagnosed with renal masses. These are often small and may not require any treatment but cause a great deal of anxiety. Treatment is tailored to the patient and includes laparoscopic partial nephrectomy, radio frequency ablation and observation.
If referring a patient with a renal mass or complex cyst or other lesion for evaluation the most useful test to perform is a CT renal 3 phase. This will provide non contrast, arterial, portal venous as well as delayed images.
