We compared the oncological outcomes of papillary renal cell carcinoma (pRCC) with clear cell renal cell carcinoma (ccRCC) after partial nephrectomy (PN) in patients with pathologic T1a RCC.
After excluding patients with synchronous multiple renal tumors, familial RCC, and pathologic stage T1b or above, 759 patients with ccRCC and 84 patients with pRCC were included.
