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 triple phase renal (abdominopelvic) CT is recommended for all renal masses
Simple cysts on ultrasound or CT do not require further evaluation.
