Abstract: Objective To evaluate efficacy of the 2004 World Health Organization (WHO)/International Society of Urological Pathology (ISUP) classification in prediction of recurrence, progression and cancer-specific mortality. Methods The dates of 384 patients who underwent transurethral resection of primary urothelial tumors were retrospectively studied. Results The difference of recurrence, progression and cancer-specific mortality rate among 6 groups was significant (P<0.05), and progression and cancer-specific mortality rate between Ta and T1 stage was significant (P<0.05). Conclusion WHO2004 pathological classification of urothelial tumors could well reflect the outcome of the patients with bladder urothelial tumors and it is useful to estimate the tumors progress.

Key words: urothelial tumors, WHO pathological classification, prognosis, recurrence
