Abstract］ objective to assess the efficacy and safety of transurethral resection of prostatewith plasmakinetic technique and to improve the qualities of pkrp.methods the data of 273 patients with benign prostatic hyperplasiawere retrospectively studied baseing on the mastering of pkrp.the average maximum urinary flow rate,the average residual urinary volumeand the average international prostate symptom score were analysed.results pkrp was successfully performed on 273 patients.intraoperative blood transfusion was performed in 6 cases,no obturator nerve reflex,transurethral resection syndrome,permanent urinary incontinence occurred and no death cases occurred.the follow-up time was 2～26 months with an average of 5.63 months,postoperative average qmax increased to 15.9 ml/s,and ruv decreased to 16.0 ml/s and the average ipss was 9.compared with those of preoperation,the differences were significant.conclusion pkrp has superior tissue cutting function and hemostasis.it is suggested that transurethral bipolar plasmakinetic resection of prostate be effective and safe.
