Benign prostatic hyperplasia (BPH) is one of the most common diseases in older men, and its incidence is increasing every year as people live longer. about 20% of older men with BPH over the age of 50 require surgical treatment. Minimally invasive treatment is widely used because of its minimal damage, quick recovery, and efficacy. The traditional transurethral resection of the prostate (TURP) has been the gold standard for BPH for more than 70 years and was first introduced by Gyrus in 1998 as a minimally invasive treatment for BPH. Because of its many advantages over conventional TURP surgery, plasma TURP surgery has now challenged the “gold standard” status of conventional TURP surgery. The author was the first to perform plasma TURP surgery, also known as PKRP, in China, and has performed more than 1500 PKRP surgeries in total, and has systematically studied the features and advantages of PKRP compared to traditional monopolar TURP through animal and clinical trials. The surface temperature during cutting is 40 -70℃ . The high-frequency current only forms a local circuit and does not pass through the body, so the thermal penetration is not deep, which can reduce the damage to the erectile nerve outside the envelope and reduce the occurrence of erectile dysfunction after surgery. The use of saline as the irrigation solution, with little fluid absorption, allows the removal of large prostate bodies without the occurrence of TURS. The procedure can also be performed successfully on large prostate glands larger than 80 grams. ③No need to use negative plate, which improves safety and avoids the impact on the pacemaker. ④The coagulation layer formed is thicker and has a better hemostatic effect. ⑤ The thin carbonized layer of the cutting process has less coagulation and coking effect on the resected tissue, which is beneficial for pathological examination and has less postoperative urinary tract irritation [7]. Because of these advantages, plasma bipolar electroprostectomy is considered a great improvement over conventional TURP. For patients with indications for PKRP surgery, contraindications are often relative. Neither elderly patients nor patients with large prostates are absolute contraindications to surgery. For a skilled and experienced surgeon, no prostate of any size is contraindicated unless the patient has severe cardiac or pulmonary disease or significant abnormal liver function that prevents him from tolerating the procedure. Traditional electrodesection of the prostate is generally not recommended for prostates over 80 grams. However, we use plasma bipolar electrosurgery to remove a maximum of more than 200 grams of prostate in patients up to 99 years of age. The bladder is flushed for 1-2 days after surgery, and the catheter is removed and discharged 3-5 days after surgery.
