Marc Garnick, Oncology, answeredIn the treatment of benign prostatic hyperplasia (BPH) transurethral electrovaporization of the prostate (TUEVP) is similar to transurethral resection of the prostate (TURP), an incision-free surgical procedure that cuts away excess prostate tissue with an electrical loop, in that a resectoscope is inserted into the penis and threaded up into the prostate. But instead of a wire loop that cuts away overgrown prostate tissue, the resectoscope has a roller-ball electrode at the end. Electrical energy quickly heats, vaporizes, and cauterizes prostate tissue, minimizing bleeding. A catheter is then inserted into the bladder.
