A New Technique for Transurethral Resection of Bladder Tumors: Rotational Tumor Resection Using a New Arched Electrode

PURPOSE: A new technique of transurethral resection of bladder tumors is described. MATERIALS AND METHODS: A 2.5 cm. papillary, sessile bladder tumor was treated via a rotational resection technique with a new arched electrode to replace longitudinal resection using a conventional loop electrode. RESULTS: This method was easy to perform and allowed for en bloc resection of bladder tumor. CONCLUSIONS: This rotational resection technique is useful for evaluation of pathological depth of tumors in resected specimens.
