Abstract

Purpose: This study investigates the utility of ureteroscopic surgery (URS) as an alternative to radical nephroureterectomy (RNU) in managing upper tract urothelial carcinoma (UTUC), with a focus on survival outcomes and re-evaluation of current the European Association of Urology guidelines criteria. Methods: We conducted a retrospective, multi-institutional review of 143 UTUC patients treated with URS (n = 35) or RNU (n = 108). Clinicopathological factors were analyzed, and survival outcomes were assessed using Kaplan–Meier analysis and Cox proportional-hazards models. Results: The median follow-up period was 27 months. Overall survival (OS) and radiographic progression-free survival (rPFS) were comparable between the URS and RNU groups (OS: HR 2.42, 95% CI 0.63–9.28, P = 0.0579; rPFS: HR 1.82, 95% CI 0.60–5.47, P = 0.1641). URS conferred superior renal function preservation. In patients characterized by factors such as radiographically invisible lesions, negative cytology, pTa stage, low-grade tumors, and multiple lesions, the OS outcomes with URS were comparable to those with RNU as follows: radiographically invisible lesions (P = 0.5768), negative cytology (P = 0.7626), pTa stage (P = 0.6694), low-grade tumors (P = 0.9870), and multiple lesions (P = 0.8586). Conclusion: URS offers survival outcomes similar to RNU, along with better renal function preservation, especially in low-risk UTUC patients. These findings underscore the urgency of re-evaluating the current EAU guidelines and encourage further research into determining the ideal patient selection for URS in UTUC treatment.
