RENAL MASSES WORKUP
Most renal masses are incidentally found and the patient is asymptomatic.
Most solid renal masses with vascularity are malignant although a mass <4cm can be benign in up to 20-25% of the time.
A CT scan of the chest, abdomen and pelvis triple phase renal is recommended for all renal masses.
Simple cysts on ultrasound or CT do not require further evaluation.
