De Ritis ratio (aspartate transaminase/alanine transaminase) as a significant prognostic factor with upper urinary tract carcinoma who underwent radical nephroureterectomy and adjuvant chemotherapy

We investigate the correlation between preoperative De Ritis ratio (aspartate transaminase [AST]/alanine transaminase [ALT]) and postoperative clinical outcome in patients with upper urinary tract carcinoma (UTUC) who underwent radical nephroureterectomy (RNU) and adjuvant chemotherapy (ACH)
