A new technique for transurethral resection of bladder tumors: rotational tumor resection using a new arched electrode.

Abstract

A new technique of transurethral resection of bladder tumors is described. 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. This method was easy to perform and allowed for en bloc resection of bladder tumor. This rotational resection technique is useful for evaluation of pathological depth of tumors in resected specimens.
