ABSTRACT
The role of a routine second transurethral resection in evaluating and management of patients with bladder tumor is defined. From January 2004 to October 2006, 100 patients with new or recurrent bladder tumors underwent repeat transurethral resection within 4-6 weeks after the initial resection, and the results, including the presence of residual tumor and tumor stage, were compared. Of 100 cases, 28 [28%] had no tumor and 72[72%] had residual tumor on repeat TUR. Out of 64 cases with superficial [Ta, Tis, T1] bladder tumors, 20[31%] had residual non-invasive tumor and 13 [20%] were upstaged to muscle invasive tumor. Among 36 patients with a muscle invasive tumor, 10[28%] had no residual tumor on re-TURBT. Results of second resection had changed treatment option in 39 patients [39%] from the initial treatment recommendation which was given after the first TUR. Many patients with bladder tumor have residual tumor present after an initial TUR. Routine repeat resection is advised to control noninvasive tumors and to detect residual tumor invasion
