ABSTRACT
Objeodve To discuss the safety and efficacy of " point-line-surface" three step method of straight light beam green laser photoselective vaporesection of the prostate(PVRP) for the treatment of benign prostatic hyperplasia(BPH).Methods The data of one hundred and twenty-six BPH patients who were treated with surgery in the First Affiliated Hospital of Xinxiang Medical University from May 2016 to August 2017 was analyzed retrospective.In all of the patients,69 cases were given "point-line-surface" three step method of straight light beam green laser PVRP(PVRP group),57 cases were given photoselective vaporization of the prostate (PVP group).Operation time,blood loss,postoperative washing time,indwelling catheter time,international prostate symptom score (IPSS),quality of life score (QOL),maximum urinary flow rate (Qmax) and postvoid residual urine (PVR) were compared between the two groups.Results The operation time in the PVRP group was shorter than that in the PVP group(P ＜ 0.05).There was no significant difference in the blood loss,postoperative washing time and indwelling catheter time between the PVRP group and PVP group(P ＜ 0.05).There was no significant difference in the IPSS,QOL,Qmax and PVR between the PVRP group and PVP group before operation (P ＜ 0.05).In the two groups,the IPSS,QOL and PVR were lower after operation than that before operation (P ＜ 0.05),while Qmax was higher after operation than that before operation(P ＜ 0.05).There was no significant difference in the IPSS,QOL,Qmax and PVR between the PVRP group and PVP group after operation(P ＜ 0.05).The rate of postoperative complications in the PVRP group and PVP group was 1.4％(1/69) and 1.8％ (1/57),respectively;there was no significant difference in the rate of postoperative complications between the PVRP group and PVP group (x2 =11.968,P ＜ 0.05).Conclusion " Point-line-surface" three steps of straight light of PVRP for treating BPH have simple steps and short operation time.It is a safe and ideal surgical method for BPH.
