Evaluation of the Role of Early Second Look Cystoscopy after Complete Resection of Non-Muscle Invasive Bladder Tumors

Abstract

T he role of second TURBT two to six weeks after initial diagnosis of non-muscle invasive bladder cancer has been a subject of controversy among urologists, who have been divided into two main groups. One group believe that residual tumor is rare and found in only 7% to 11%, and when present it has only a 1.5% risk of progression over a period of three months until the time of first-check cystoscopy (Millán-Rodríguez et al., 2000). In contrast, other investigators emphasized the significance of second TURBT in separating between true tumor recurrence and residual tumor, which has been incorrectly classified as tumor recurrence. Thus, the most important prognostic factor in NMIBC is tumor recurrence at three months after initial TURBT (Herr et al., 2008).
