However, issues that have not yet been overcome for TURP include bleeding and absorption of irrigation fluid. Thus, novel improvement of the surgery is necessary. This study aimed to evaluate the efficacy and safety of bipolar plasma vaporization of the prostate （BPVP） with ＂button-type＂ electrode against standard TURP for BPH.展开更多
目的:探讨经尿道前列腺剜除术(Transurethral enucleative resection of prostate,TUERP)与经尿道双极等离子前列腺电切术(Transurethral plasma kinetic resection of the prostate,TKRP)治疗高危前列腺增生症(Benign prostatic hyperp...目的:探讨经尿道前列腺剜除术(Transurethral enucleative resection of prostate,TUERP)与经尿道双极等离子前列腺电切术(Transurethral plasma kinetic resection of the prostate,TKRP)治疗高危前列腺增生症(Benign prostatic hyperplasia,BPH)的安全性和临床疗效。方法:回顾性分析67例高危BPH患者的手术方式,就两种手术方式的前列腺切除重量、手术时间、术中出血量、术后膀胱持续冲洗时间、留置导尿管时间、手术并发症、术后住院时间进行比较;同时对两组术前与术后国际前列腺症状评分(International prostate symptom score,IPSS)、生活质量(Quality of life score,QOL)、最大尿流率(Maximum flow rate,Qmax)、残余尿量(Postvoid residua,PVR)进行比较。结果:31例TUERP,36例行TKRP,术前2组患者一般情况比较无统计学差异(P>0.05);术后各组患者IPSS、QOL、Qmax、RVR与术前比较差异有统计学意义(P<0.01),但组间比较均差异无统计学意义(P>0.05)。手术时间、术中出血量、术后膀胱冲洗时间、住院时间TUERP组明显小于TKRP组(P<0.05),前列腺切除率TUERP组显著高于TKRP组(P<0.05)。结论:TUERP与TKRP对治疗高危BPH疗效差异无统计学意义,TUERP手术时间、术后膀胱冲洗时间和住院时间较短,术中出血量、并发症少。展开更多
