[The use of new technologies in the endoscopic electrosurgery of benign prostatic hyperplasia of large dimensions]

The technique of electrovaporization, a novel low-traumatic method, has been practiced in the Research Institute of Urology (Moscow) for the treatment of benign prostatic hyperplasia (BPH) since 1995. This technique is based on the standard transurethral resection (TUR) being superior in the absence of intraoperative bleeding. Its application, however, is restricted to hyperplasia of small and moderate size. But TUR, in its turn, provides more rapid removal of the tissue. These advantages of the two techniques were combined in the treatment of extensive BPH. Compared to TUR, standard TUR combination with electrovaporization proved much more effective. Progressive techniques in endoscopic surgery comprise also use of novel resection electrodes which differ from the previous analogues by thickness, shape and coating. When used in electroresection, such electrodes provide simultaneous removal of the tissue, electrovaporization and coagulation of the underlying tissues. The above technical innovations allowed advance in the quality of endoscopic interventions, widening indications for endoscopic electrosurgical management of large-size BPH and decreasing the incidence of relevant complications.
