We have performed transurethral microwave tissue coagulation (MTC) for urinary bladder cancer, and especially applied MTC to small recurrent tumors without anesthesia. We report 2 patients who underwent MTC for urinary bladder cancer as a primary therapy without anesthesia. Both cases were old age with some complications. One was 92-year-old man who had been performed pancreatoduodenectomy and colectomy, and medicated for diabetes and angina pectoris. Papillary tumor of posterior wall (3mm in diameter, UC, G2) was treated. After 11 months, MTC was performed for recurrent tumor which was 3mm in diameter. Another case was 90-year-old man with dementia. Papillary 10mm tumor was able to treat by MTC alone without anesthesia. It is supposed that MTC without anesthesia could be applied to small bladder cancer as a primary therapy.
