[Oncological outcomes of laparoscopic and open treatment (nephroureterectomy) for urothelial tumors of the upper urinary tract].

Currently, the treatment of choice in urothelial tumors of the upper urinary tract is nephroureterectomy (NU) as an Open procedure (ONU), though the laparoscopic treatment is now routinely performed as a minimally invasive therapy (LNU). LNU has demonstrated oncologic safety at least equivalent to open, but some issues dealing with cancer still remain. We retrospectively analyzed data from 36 LNU performed between 2006 and 2010, compared with data of 32 ONU performed in 2002-2005 (pre-laparoscopy era).
