title: [Prospective study of effectiveness. Reoperation (re-TUR) in superficial bladder carcinoma].
abstract: To assess the rate of residual cancer after transurethral resection (TUR) of superficial bladder cancer, a prospective study was carried out. All patients with transitional cell cancer (TCC) stage pTa-pT1 underwent a repeat TUR (ReTUR) within 6-8 weeks. Sites and rates of tumors found during ReTUR were documented as well as the morbidity of the ReTUR. Of a total of 192 TUR, superficial TCC was found in 124 cases; 83 underwent ReTUR according to the study protocol. Residual tumor was detected in 27% of pTa and 53% of pT1 tumors. Worsening of grading or T stage was found in 8%. Of the tumors detected by ReTUR, 81% were localized at the site of the first TUR. In this prospective study, residual tumor formation was detected in a high percentage. Routine ReTUR is therefore recommended in superficial bladder cancer except solitary pTaGI lesions.
