Primary urothelial carcinoma of the upper tract: important clinicopathological factors predicting bladder recurrence after surgical resection.

The aim of the present study was to further characterize potential clinicopathological predictors for urinary bladder recurrence-free survival (UBRFS) in patients with primary urothelial carcinoma of the upper urinary tract (UUT-UC). The present series included 385 cases of surgically treated primary localized UUT-UC without previous or concurrent urothelial carcinoma of the urinary bladder. Among the 374 patients with follow-up information, clinicopathological features and therapeutic information including whether they received a laparoscopy-assisted nephroureterectomy (LNU) and adjuvant chemotherapy were correlated with UBRFS.
