—Beer,43 at the Third Congress of the Society of International Urologists, stated that the employment of high frequency currents through the cystoscope has given excellent results in the treatment of tumors of the bladder. There are known differences in the action of the unipolar and bipolar current. The unipolar is more explosive and of a higher tension and requires greater amperage. The action of the bipolar current is more useful in producing extensive coagulation of the pedicle of a tumor. When the bladder is open, the papilloma may be held up with a clamp and the bipolar current allowed to penetrate through the tumor, which produces coagulation that extends through the pedicle in the adjacent wall of the bladder.Beer has had excellent results in the endoscopic treatment of vesical tumors in 158 cases. In about 20 per cent of the cases, there were recurrences. Recurrences in
