Effect and safety of transurethral plasmakinetic resection of prostate for patients with benign prostatic hyperplasia

Objective To investigate the effects and safety of transurethral plasmakinetic resection of prostate (PKRP)on benign prostatic hyperplasia (BPH). Methods The clinical data of 84 patients with BPH treated in the People’s Hospital of Linyi from May 2015 to April 2017 were retrospectively analyzed. Patients were divided into control group (42 cases) and study group (42 cases) according to the random number table method. Patients in control group were treated by transurethral resection of prostate (TURP), and patients in study group were treated by PKRP. The operation conditions, urethral function [maximum urinary flow rate (Qmax), residual urine volume (RUV), prostate symptom (IPSS) score], sexual function[retrograde ejaculation rate, erectile dysfunction (IIEF-5) score and erectile dysfunction rate] and complications were statistically analyzed between the two groups. Results There was no significant difference in the quality of prostatectomy between the two groups (P>0.05). The duration of operation, intraoperative blood loss, bladder irrigation time, indwelling catheter time, hospital stay in study group were significantly less than those in control group (P<0.05). At 6 months after operation, the Qmax of the two groups increased, and the scores of RUV and IPSS decreased compared with those before treatment; the Qmax of study group was larger than that of control group, and the scores of RUV and IPSS were smaller than those of control group (P<0.05). At 6 months after operation, the rates of retrograde ejaculation and erectile dysfunction in the two groups were lower than those before operation, and the IIEF-5 scores were higher than those before operation; the reverse ejaculation rate and erectile dysfunction rate in study group (7.14%, 4.76%) were lower than those in control group (23.81%, 21.43%), and the IIEF-5 score was higher than that in control group (P<0.05). The incidence of complications in study group (7.14%) was lower than that in control group (23.81%, P<0.05). Conclusions Transurethral plasmakinetic resection of prostate in the treatment of patients with BPH can reduce the surgical trauma, shorten hospital stay, and improve the urethral function and sexual function of the patients. Moreover, it has less complications and high safety. Key words: Transurethral plasmakinetic resection of prostate; Benign prostatic hyperplasia; Urethral function; Safety
