We compared pathological characteristics and survival data among groups with Wilcoxon's rank sum tests, Pearson's chi-squared, and the Kaplan–Meier method.</div></div><div><h3>Results</h3><div>In the sUTUC-BUC group, a higher proportion of patients exhibited UTUC tumors with grade G3 (56%, <em>P</em> = .001) and stage T4 (6%, <em>P</em> &lt; .001) than group UTUC-mBUC (G3 = 16%, T4 = 0%). The proportion of patients with variant histology subtype in group sUTUC-BUC was higher than that of metachronous UTUC-BUC, involving squamous (<em>P</em> = .003), adenoid (<em>P</em> = .012), and sarcomatoid (<em>P</em> &lt; .001) differentiation. It was also observed that the maximum diameter of the UTUC tumor of group sUTUC-BUC (median = 3.5) was significantly larger than group UTUC-mBUC (median = 2.5, <em>P</em> = .002) and group BUC-mUTUC (median = 2.2, <em>P</em> &lt; .001). Notably, sUTUC-BUC has an increased risk of cancer-specific death compared with UTUC-mBUC (<em>P</em> &lt; .001) and BUC-mUTUC (<em>P</em> &lt; .001). On multivariable Cox regression, synchronous UTUC-BUC was an independent predictor of both RFS (<em>P</em> &lt; .001; vs. UTUC-mBUC: HR 0.555, <em>P</em> = .004; vs. BUC-mUTUC: HR 0.279, <em>P</em> &lt; .001) and CSS (<em>P</em> &lt; .001, HR 29.737).
