Lymph node yield and tumor location in patients with upper tract urothelial carcinoma undergoing nephroureterectomy affects survival: A U.S. population-based analysis (2004-2012)

In patients with upper tract urothelial carcinoma undergoing nephroureterectomy, rates of lymphadenectomy have increased from 2004 to 2012 in the United States. In this contemporary cohort, an increase in the number of nodes removed and renal pelvis tumors are associated with improved cancer-specific survival, which highlights the importance of intentional lymph node dissection with adequate lymph node yield in these patients.
