Purpose: To evaluate predictor factors of increasing intravesical recurrence rate in patients with upper tract urothelial carcinoma (UTUC) after receiving radical nephroureterectomy (RNUx) with bladder cuff excision (BCE).

Materials and Methods: A total of 2,114 patients were divided into two groups: Intravesical recurrence (IVR)-free and IVR after RNUx, with 1,527 and 587 patients, respectively. To determine the factors affecting IVR, TNM stage, the usage of preoperative ureteroscopy, and pathological outcomes were evaluated. The Kaplan-Meier estimator was used to estimate the rates of prognostic outcomes in overall survival (OS), cancer-specific survival (CSS), disease-free survival (DFS), and bladder recurrence-free survival (BRFS), and the survival curves were compared using the stratified log-rank test.

Results: Based on our research, ureter tumor, female, smoking history, old age (>70 years old), multifocal tumor, history of bladder cancer were determined to increase the risk of IVR after univariate analysis. The multivariable analysis revealed female (BRFS for male: HR 0.566, 95% CI 0.469-0.681, p<0.001), ureter tumor (BRFS: HR 1.359, 95% CI 1.133-1.631, p=0.001), multifocal (BRFS: HR 1.200, 95% CI 1.001-1.439, p=0.049), history of bladder cancer (BRFS: HR 1.480, 95% CI 1.118-1.959, p=0.006) were the prognostic factor for IVR. Patients who ever received ureterorenoscopic biopsy did not increase the risk of IVR.  

Conclusion: Patients with ureter tumor and previous bladder UC history are important factors to increase the risk of IVR after radical nephroureterctomy. More frequent follow-up regimen may be needed for these patients.
