What is transurethral electrovaporization (TUEVP) of the prostate?

In 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.
