Prospective Analysis of Computerized Tomography and Needle Biopsy With Permanent Sectioning to Determine the Nature of Solid Renal Masses in Adults

Abstract

Overall permanent biopsy results were accurate in more than 72% of cases and CT was accurate in more than 60%. However, because the nondiagnostic rate for CT and needle biopsy was 20% and 31%, respectively, and specificity was low, we do not recommend routine preoperative CT and subsequent needle biopsy to guide treatment decision making. Rather, cases must be decided individually.
