Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

Retrospective studies indicate that active surveillance for clinically localized, small renal masses (cT1a, \<=4cm) is safe. It is our hypothesis that active surveillance is safe and efficacious when compared prospectively to patients undergoing immediate intervention for their small renal mass.
