Objectives:
To study the incidence of "residual/recurrence" tumor after a second bladder resection (2nd TUR).
Methods:
40 patients with new or recurrent superficial bladder tumor underwent repeat transurethral resection within 3 months after the initial resection. 37 patients were staged as Ta-T1. We study the incidence of tumor after the 2nd TUR both macroscopically detected or included in the bladder scar. We also study the influence of possible factors as the time between both resections, stage, grade, number of tumor size, localization in the bladder, primary or recurrent tumor and tumor pattern.
Results:
After the 2nd TUR we found tumor in 14 of 37 (37.8%) Ta-T1 bladder tumors. Among the 14 tumors, 10 (71.5%) were macroscopically visible tumors and 4 cases the tumor were found after resection of the bladder scar of the first resection. We did not find relation between the presence of tumor in the 2nd TUR and any of the variables.
Conclusions:
After a TUR of superficial bladder tumor the complete removal of tumor is not always achieved. The early 3 months cystoscopy may not find residual tumor. Although we have found tumor in 37.8% in the 2a TUR we can not recommend routine 2nd TUR in superficial bladder cancer.
