目的比较经尿道刀口变向钬激光前列腺剜除术(turning holmium laser enucleation of prostate,THolEP)与经尿道前列腺电切术(transurethral resection of prostate,TURP)+膀胱颈切开术(transurethral incision of bladder neck,TUIBN)...目的比较经尿道刀口变向钬激光前列腺剜除术(turning holmium laser enucleation of prostate,THolEP)与经尿道前列腺电切术(transurethral resection of prostate,TURP)+膀胱颈切开术(transurethral incision of bladder neck,TUIBN)治疗小体积前列腺增生(benign prostatic hyperplasia,BPH)的疗效和安全性。方法选取2019年1月至2020年1月在我院手术治疗的小体积BPH患者65例,随机分为两组,分别行THolEP术(THolEP组,33例)和TURP+TUIBN术(TURP+TUIBN组,32例)。比较两组手术指标及术后1、3、6、12、18个月国际前列腺症状评分(international prostate symptom score,IPSS),生活质量(quality of life,QOL)评分,最大尿流率(Qmax),残余尿量(residual urine volume,RUV)及术后逆行射精发生率。结果两组手术均顺利完成,均未发生电切综合征。THolEP组术中切除组织量大于TURP+TUIBN组(P<0.05),而两组手术时间、术中出血量比较,差异无统计学意义(P>0.05)。THolEP组和TURP+TUIBN组术中发生前列腺包膜穿孔分别为1例和6例,术后1周发生压力性尿失禁分别为2例和8例,组间比较差异有统计学意义(P<0.05)。行盆底肌收缩训练3个月后两组均无尿失禁病例。术后2个月TURP+TUIBN组1例出现尿道狭窄,定期进行尿道扩张后缓解。两组患者均于术后1、3、6、12、18个月进行随访。两组术后各时点IPSS、QOL、Qmax及RUV均较术前明显改善(P<0.05);组间比较,THolEP组术后各时点上述指标均明显优于TURP+TUIBN组(P<0.05)。术后6、12、18个月随访逆行射精发生率,TURP+TUIBN组分别为31.3%、28.1%及28.1%,明显高于THolEP组的9.1%(P<0.05)。结论THolEP肌层无损伤解剖性松解膀胱颈治疗小体积BPH,疗效确切,症状缓解明显,并发症少,值得临床推广。展开更多
