Abstract
Bipolar radio frequency (rf) transurethral prostate coagulation is a treatment method for benign prostatic hyperplasia through an rf current applied though three needle microelectrodes inserted in the urethra wall. A set of in vitro studies on beef muscle were performed to investigate the feasibility of altering the electrodes' polarity to increase the coagulated zone volume. Overall, the proposed approach increases the volume of coagulated tissue by a factor of two almost independent of the polarity alteration frequency. However, rapid alteration could lead to explosive vaporization of water trapped in the tissue which could, in turn open a passage for hot water deep into the tissue and increase the coagulation zone.
