Of 96 cases with superficial (Ta, Tis, T1) bladder tumors 72 (75%) had residual noninvasive tumor and 28 (29%) were up staged to invasive tumor. Among 54 patients with a muscle invasive tumor 12 (22%) had no residual tumor on repeat transurethral resection. Results of the second resection changed tumor treatment in 50 patients (33%).\nCONCLUSIONS: Many patients with bladder tumors have tumor present after an initial trans-urethral resection. Routine repeat resection is advised to control noninvasive tumors and to detect residual tumor invasion."}
