Greenlight photoselective vaporization of the prostate for the treatment of enlarged benign prostatic hyperplasia

Objective To evaluate the efficacy of greenlight photoselective vaporization of the prostate(PVP) for the treatment of enlarged benign prostatic hyperplasia,Methods Retrospective analysis was performed in 78 benign prostrate hyperplasia patients under-going the PVP treatment,whose prostate volume was more than 80ml.Operative data,hospitalization periods,catheter removal,international prostate symptom score(IPSS),maximum flow rates(Qmax),prostate volume and complications were recorded.Results The PVP was successfully performed on all the 78 patients,none of them received blood transfusion and TUR syndrome.The operative time was(81.4±7.6)min and the postoperative urinary catheter time was(3.5±1.3)d.The rate of acute urinary retention,irritation and infection were 11.5%,26.9% and 12.8% respectively.A significant improvement was observed in Qmax,IPSS values and prostate volume at 1 month.39 cases were followed up 10 to 48 months after treatment,one patient was urinary incontinence and 6 cases need reoperation.Conclusions Although PVP offers advantages in intraoperative safety,early complication was higher in PVP that limited it' s use in patients with enlarged prostates larger than 80 ml.
