Resection for benign prostatic hyperplasia by transurethral surgery and plasma bipolar effects: Cases of urinary incontinence are fully recovered in three months; two cases of postoperative epididymitis, and heal within two weeks. In the PKRP group, 6 patients had intraoperative or postoperative bleeding, one of whom underwent open surgery, with five cases requiring intraoperative blood transfusion due to urethral stricture. One patient was cured after expansion. TURP surgery has been recognized as the gold standard, but because it features a cutting principle that requires crystal-free medium liquid rinse, blood loss is not easy to control, re-heat penetrating injury is prone, and there's a risk of transurethral resection syndrome (TURs). Therefore, the surgical indications and surgical time are subject to certain restrictions, especially for patients with too large prostate volume, where the procedure is particularly cautious. TURP surgery uses a monopolar electrode loop, which can easily lead to short-circuit of the electrode and mirror sheath, causing urinary tract burns and increasing the chances of urethral stricture (especially outside the mouth). According to the literature [1.3] reported, the complication rate of TURP postoperatively is 13.4%, and 18 severe cases can lead to death. The bipolar plasma vaporization cut endoscope system (PKRP), launched in 1998, is a product different from the monopolar electrode TURP resectoscope used for clinical transurethral resection of the prostate [2]. By 2000, it was reported that over 600 cases of PKRP treatment in China have shown satisfactory results. PKRP principle: electric cutting loop with two electrodes simultaneously, one as the working electrode, a loop electrode, the loop current passes through two electrodes, ionizing the surrounding medium (normal saline) into a first-class ion beam, breaking the organic molecules bonds of the target tissue, resulting in the fragmentation and vaporization of the target tissue. The principle is similar to TURP surgery, but the surface temperature of the target tissue cut by PKRP is 40 ~ 70°C, causing less damage to the surrounding tissue, mild postoperative urethral irritation, no negative plate on adjacent organs and tissues, no current passing through, thus reducing the obturator nerve reflex opportunities [3] and less intraoperative blood loss. PKRP surgery improves surgical safety, is less susceptible to prostate volume size limit, and also increases the rate of tissue removal. This group's results show that the efficacy of the two surgical techniques is similar, but the incidence of complications in PKRP was significantly lower than in TURP, indicating PKRP is safer than TURP. After 3 months of follow-up, results show no significant difference in Qmax between the two groups of patients. To sum up, PKRP is a safe and effective surgery, with a wider range of indications, and is worth applying clinically. However, the number of this group of patients is still small, with limited follow-up time, so its long-term effects need to be observed further in future case accumulation and comparative study.
