Algorithm for management of patients with a small renal mass in the Delayed Intervention and Surveillance for Small Renal Mass (DISSRM) Registry. Axial imaging entails CT or MRI. CBC, complete blood count; CMP, comprehensive metabolic panel; PT/PTT, prothrombin time/partial thromboplastin time; QOL, quality of life. *Ultrasound is the preferred imaging modality; however, CT or MRI is typically used in an alternating fashion with ultrasound and may be used at the discretion of the physician in the case of uncertainty or changes in ultrasound findings. **Chest imaging (eg, chest radiograph) is no longer recommended on an annual basis without cause. Please refer to the body of the text and Figure 3.
