ABSTRACT
Objective To observe the recent effect and safety of minimally invasive transurethral double pole plasma-prostatectomy (PKEP) for the treatment of the benign prostatic hyperplasia (BPH). Methods One hundred and twenty-six patients with BPH were selected by parallel group design, and divided into two groups by piecewise equilibrium stochastic method. Sixty-three patients in the control group were treated with transurethral prostate electrotomy (TURP). The study group of 63 patients was treated with PKEP. Weight, operation time, intraoperative bleeding and complications of the patients were recorded. Three months after surgery, the maximum urine flow rate (Qmax), residual urine volume (PVP), international prostate symptom score(IPSS)and quality of life score(QOL)was used to evaluate the improvement of symptoms. Results The average operation time, postoperative hospital stay, time placing a urinary catheter in study group was shorter than that in the control group(50.2 ± 8.5)min vs (62.4 ± 10.3)min,(5.0 ± 0.7)d vs.(6.4 ± 1.2)d,(38.4 ± 2.7)h vs.(80.5 ± 6.9)h,intraoperative blood loss was less than that in the control group, (62.4 ± 13.7)ml vs.(91.6 ± 23.5)ml,and removing tissue volume was better than that in the control group (53.4 ± 5.9) g vs. (39.6 ± 7.2) g. Differences were statistically significant (P < 0.05). After surgery, the PVP significantly reduced, Qmaxincreased significantly, the IPSS and QOL scores significantly reduced, and the differences were statistically significant(P<0.05). However, there was no significant difference between PVP, Qmax, IPSS and QOL in the two groups(P>0.05).The incidence of postoperative complications in the study was 30.16%(19/63), significantly lower than that of the control group(46.03%,29/63), and the difference was statistically significant(P<0.05). Conclusions PKEP is better than TURP in the treatment of large volume BPH of old age, and PKEP is safer than TURP.
