Currently there are two types of treatments: open surgery and minimally invasive surgery (transurethral prostatectomy). Transurethral resection of prostate is known as the gold standard of prostate hyperplasia treatment, patients do not need scalpel incision for open surgery, but the cysto-electrosurgical scope is inserted from the urethra and directly reaches the prostate area, and the electric current is utilized under direct observation to vaporize the resected tissues through vaporization cutting effect, so that the tissue to be resected is heated and vaporized rapidly, and the resected surface produces a protein-coagulated layer that is as deep as 2 to 3 mm, thus effectively reducing the cutting process This effectively reduces bleeding and fluid absorption during the cutting process. Surgery has the advantages of less bleeding, no surgical incision, less trauma, fast postoperative recovery and good therapeutic effect. Moreover, the scope of the surgery is wider, not only the patients who need to do open surgery can perform transurethral electrolysis, but also many patients who have comorbidities and can’t perform larger open surgery can also be relieved of pain through this surgery.
