Objective:

We aimed to investigate the significance of time to re-staging transurethral resection (re-TUR) on recurrence and progression rates in patients with high-risk non-muscle-invasive bladder cancer as a prospective randomized study.

Methods:

The patients were randomly separated into three groups according to Re-TUR timing. In Groups 1, 2, and 3, the time interval between initial and re-TUR was 14-28 days, 29-42 days, and 43-56 days, respectively. Cox regression analysis was used to assess the effect of time from initial TUR to re-TUR on oncological outcomes.

Results:

Twenty patients in Group 1 (14-28 days), 22 patients in Group 2 (29-42 days), and 29 patients in Group 3 (43-56 days) completed the study. Kaplan–Meier plots showed no differences in recurrence-free survival (RFS) and progression-free survival (PFS) rates between the three groups. Cox regression analysis demonstrated that only tumor number was found to be a prognostic factor on RFS rates.

Conclusion:

Our prospective study demonstrated that time laps from initial TUR to re-TUR did not significantly affect on RFS and PFS rates.
