Abstract：Objective To investigate the clinicopathological risk factors for intravesical recurrence ( IVR) in patients undergoing radical nephroureterectomy (RNU) for upper urinary tract urothelial carcinoma (UUT-UC).Methods The postoperative follow-up was conducted in 209 patients who underwent RNU for UUT-UC, and the case of IVR was recorded . We analyzed the relationships between the clinical and pathological features of UUT -UC with IVR.The Log-rank test was used to calculate survival functions .Results Of 209 patients, 59 cases (28.2%) developed IVR after RNU.The IVR rate of multifocal tumors was 46.0%, which was significantly higher than that of the single tumor (22.0%) (P<0.01). The IVR rate in patients who underwent preoperative ureteroscopy was 46.7%, which was significantly higher than those who did not undergo ureteroscopy (31.5%) (P<0.01).Conclusions Tumor multifocality and diagnostic ureteroscopy are the risk factors in developing IVR after RNU for UUT-UC.
