Laparoscopic versus open nephroureterectomy to treat localized and/or locally advanced upper tract urothelial carcinoma: Oncological outcomes from a multicenter study

Background Many studies have reported the oncological outcomes between open radical nephroureterectomy (ONU) and laparoscopic radical nephroureterectomy (LNU) of upper tract urothelial carcinoma (UTUC). However, few data have focused on the oncological outcomes of LNU in the subgroup of localized and/or locally advanced UTUC (T1–4/N0-X). The purpose of this study was to compare the oncological outcomes of LNU vs. ONU for the treatment in patients with T1–4/N0-X UTUC.
