To evaluate oncologic outcomes of segmental ureterectomy (SU) compared with radical nephroureterectomy (RNU) for ureter urothelial carcinoma of stage Ta, TI and T2.To evaluate whether tumor position is a factor to influence outcomes of different surgical procedures.From December 2004 to June 2014, 81 patients with non-serosa-invasive (Ta, T1 or T2) urothelial carcinoma of ureter underwent SU or RNU at our department.We used Kaplan-Meier survival analysis and Cox regression models to compare oncologic outcomes after SU and RNU.Covariates included surgical type, tumor stage, cancer grade, lesion position, presence of preoperative hydronephrosis and histories of bladder cancer.Patients were divided according to lesion sites for further comparison.
