Efficacy of Nephron-Sparing Surgery for Renal Cell Carcinoma: Analysis Based on the New 1997 Tumor-Node-Metastasis Staging System

Abstract

Partial nephrectomy has become an effective method of treating T1 RCC lesions as categorized by both the 1987 and the revised 1997 TNM staging criteria. Selected patients with localized unilateral RCC lesions less than 7 cm (ideally, < 4 cm) and a normal contralateral kidney will benefit from partial nephrectomy.
