High R.E.N.A.L. Nephrometry Scores Are Associated with Pathologic Upstaging of Clinical T ₁ Renal-Cell Carcinomas in Radical Nephrectomy Specimens: Implications for Nephron-Sparing Surgery

Abstract

A higher RNS was associated with an increased risk of upstaging in clinical T1 cancers, predominantly from perinephric or sinus fat invasion in RN pathologic specimens. This may have implications on the selection of surgical option for the clinical T1 renal mass.
