Abstract
We have performed transurethral microwave tissue coagulation (MTC) for urinary bladder cancer, and especially applied MTC to small tumors of outpatients without anesthesia. In this report, flexible MTC (f-MTC) with a flexible cystoscope was performed. Ten patients of recurrent bladder cancer were treated. The tumor gradings were G1 and G2 in 4 and 6 cases. Six cases had solitary tumor and 4 cases had multiple tumors. In 8 cases, tumors were up to 3 mm in diameter, and 2 cases had tumors over 5 mm. Recurrence occurred in 3 cases. One case was followed by TUR-Bt and 2 cases were followed by f-MTC. This procedure is less painful and it can be performed immediately after cystoscopy. It was useful in the treatment of small bladder cancer.
