Abstract
A retrospective study with adequate followup of 5 yr or longer of 114 patients who had transurethral resection for cure or control of bladder tumors and in whom there were 1 or more recurrences is reported. There was recurrence of the tumor in a higher grade in 19% of the cases and in a higher stage in 22%. The interval between the treatment of the original tumor and a recurrence in a higher grade or stage varied from 0.25 (3 mo.) to 27 yr. When a low grade or low stage tumor recurs in a higher category in < 3 yr more aggressive treatment should be considered.
