    Abstract: Background: To clarify if diagnostic ureteroscopy (URS) before radical nephroureterectomy for patients with upper tract urothelial carcinoma (UTUC) will increase the risk of intravesical recurrence. Methods: From retrospective review of cohort at our institution, 502 patients with UTUC who underwent radical nephroureterectomy with bladder cuff excision were enrolled from 1990 to 2013. Cox proportional hazards model was used to analyze the overall survival (OS), disease-free survival (DFS), metastasis-free survival (MFS), and intravesical recurrence-free survival (IVRFS). The log-rank test was used for comparing survival curves. All potential risk factors were included in the multivariate Cox proportional hazards model to recognize independent predictors. From NHI database, we included patients of UTUC without bladder cancer history using population-based database in Taiwan from 1996 to 2013. In total, 3079 URS and 2634 non-URS patients with UTUC were identified. Univariate and multivariate Cox proportional hazards regressions were performed to measure the risk of IVRFS and all-cause mortality. Results: From our database, the comparison of clinicopathological characteristics in UTUC patients between with URS biopsy group (URS+) (n = 206, 41%) and without URS biopsy group (URS-) (n = 296, 59%) was insignificantly different excluding surgical method. URS biopsy is not associated with worse OS (p = 0.720), DFS (p = 0.294), MFS (p = 0.808), and IVRFS (p = 0.560) by multivariate analysis. Only bladder cancer history is an independent significant factor to predict IVR (p < 0.001). The same result from NHI database, URS before radical surgery will not increase the risk of IVRFS [adjusted HR 1.136, 95% CI 1.00-1.30; P = 0.059] and OS [adjusted HR 0.919, 95% CI 0.82-1.04; P = 0.164]. Conclusions: Preoperative URS manipulation is not associated with higher risk of IVRFS even in patients without bladder cancer history. Diagnostic URS is feasible to compensate the insufficient information of image in patients with UTUC.
