Application Of160W High Power Green Laser Vaporization In The Treatment Of Benign Prostatic Hyperplasia

Objective To evaluate the safety and clinical effects of high powerphotoselective vaporization of the prostate in the treatment of benign prostatehyperplasia. Methods A total of58patients were treated with160W high powergreenlight laser.Before the operation,the volume of the prostate,IPSS,QOL,Qmax andPVR were recorded.Comparison of electrolyte and hemoglobin changes pre-andpostoperation.Catheter time and hospitalization time were recorded and analyzed.Results There are six cases used general anesthesia because of lumbar or takinganticoagulant drugs,and the remaining patients was used epidural anesthesia.Theaverage operation time was24～113min,(55.6±18.1)min.The speed of operation was1.4～1.9g/min,average (1.6±1.8)g/min,intraoperative blood loss (41.2±17.3)ml.Thecatheter was indwelled for1to5d postoperatively,average (2.4±1)d,the hospitalizationwas from3to6d,average(3.6±0.8)d.There were16cases with bladder irritation afterremoval catheter,5cases with gross hematuria,2patients with transient dysuria.58cases were followed up form3to6months.Mean Qmax increased from(6.2±2.3)ml/spreoperatively to (15.7±3.1)ml/s.IPSS、QOL and PVR improved from27.4±5.0，4.8±0.8and (158.4±54.3)ml to8.1±3.3，2.3±0.6and (31.2±22.5)ml.All the differenceswere statistically significant(P<0.05).49patients was followed up3months,45caseswere followed up6months. After operation7patients nocturia frequency>3times,3patients with retrograde ejaculation. There were2cases with secondary bleeding, andrecovered under conservative managements. There were no significant dysuria and urinary incontinence. Conclusion The160W GreenLight High Power laser is aneffective and safety method for the treatment of BPH,and especially appropriate topatients of large gland.
