Prostatic hyperplasia is a common disease in elderly men with a high incidence. The main symptoms include frequent urination, nocturia and difficulty in urination, etc. If left untreated, complications such as carnal hematuria, bladder stones, urinary tract infection, inguinal hernia, hemorrhoids, urinary retention and renal failure can seriously affect the patient’s quality of life and can eventually endanger the patient’s life. Surgical treatment is the ultimate solution when the symptoms of prostate enlargement are severe. There are various surgical options, which can be broadly divided into two categories: open surgery and minimally invasive transurethral surgery. The open surgery is only used by clinicians when the prostate is particularly large due to the large trauma and complications. The main two types of minimally invasive surgery are transurethral resection of the prostate and laser prostatectomy, and transurethral resection of the prostate has always been the “gold standard” of surgical treatment for prostate enlargement (i.e., the best results), and the advent of bipolar plasma resection has further consolidated its “gold standard” status. The emergence of bipolar plasma electrosurgery has further strengthened its status as the “gold standard”. Transurethral resection of the prostate has gone through three generations of development: (1) monopolar resection; (2) monopolar gasification; and (3) bipolar plasma cutting gasification. The working principle of bipolar plasma cutting and vaporization is: the electric current passes through the working electrode and the circuit electrode to create a circuit and release radio frequency energy, the radio frequency energy transforms the conductor medium (saline) into a highly focused plasma around the electrode, the plasma consists of highly ionized particles, these ionized particles have enough energy to break the organic molecular bonds in the prostate tissue into basic molecules and low molecules, the result is that the prostate tissue is cut. As a result, the prostate tissue is cut and vaporized. PK plasma dynamic energy technology (Plasmakinetic Technology) has been hailed as a revolution in the development of surgical technology in the 21st century, with superior characteristics such as accurate and easy to control, safe and reliable, widely used, and economical. Compared with the previous two generations of plasmapheresis, the advantages of plasmapheresis include: (1) the use of saline infusion during surgery, avoiding the risk of water poisoning (which can cause cerebral edema); (2) the surgery can be performed with ease and without time limitation; (2) the cutting is precise, and there is a vaporization effect while cutting the tissue, with good hemostasis; (3) the surface temperature of the tissue is only 40-70°C, avoiding the damage to the erectile nerve and the urinary control nerve. (3) the tissue surface temperature is only 40~70℃, avoiding the damage of erectile nerve and urinary control nerve. The advantages of plasma electrosurgery compared to laser prostatectomy are: (1) good surgical control, fine cutting, complete removal of hyperplastic prostate tissue, low recurrence rate after surgery; (2) less postoperative urinary tract irritation and less patient pain.
