The value of a second transurethral resection for T1 bladder cancer.

OBJECTIVE: To evaluate a series of repeat transurethral resections (TURs) of tumour in patients with T1 bladder cancer, usually used to ensure a complete resection and to exclude the possibility muscle-invasive disease. PATIENTS AND METHODS: In all, 136 consecutive patients had a second TUR because of a histopathological diagnosis of T1 transitional cell carcinoma (TCC) after their initial TUR. Of the 136 patients, 101 were first presentations and 35 had recurrent tumours. The second TUR was done 4-6 weeks later. The evaluation included the presence of previously undetected residual tumour, changes to histopathological staging/grading, and tumour location. RESULTS: In all, 71 patients (52%) had residual disease according to findings from specimens obtained during the second TUR. The staging was: no tumour, 65 (48%); Ta, 11 (8%); T1, 32 (24%); Tis, 15 (11%); and > or = T2, 13 (10%). Histopathological changes that worsened the prognosis (>T1 and or concomitant Tis) were found in 21% of patients. Residual malignant tissue was found in the same location as the first TUR in 86% of the patients, and at different locations in 14%. Overall, 28 patients (21% of the original 136) had a radical cystectomy as a consequence of the second TUR findings. CONCLUSIONS: A routine second TUR should be advised in patients with T1 TCC of the bladder, to achieve a more complete tumour resection and to identify patients who should have a prompt cystectomy.     «
