Guideline Compliance Regarding Chest Imaging of Suspicious cT1 Renal Masses in MUSIC-KIDNEY.

Chest imaging guideline adherence during the initial evaluation of cT1 renal masses is acceptable, particularly given that most masses are <3 cm for which metastatic risk is low. However, despite consensus from major urologic societies regarding imaging for masses >4-5 cm, imaging rates were low across MUSIC. After educational and VBR incentive initiation, rates of imaging for 3-5 cm and >5 cm masses changed only slightly. There remains significant practice variability and room for improvement.
