Study on the difference of green laser in the treatment of prostatic hyperplasia

Objective To compare the safety and efficacy of different green laser surgery in the treatment of benign prostatic hyperplasia. Methods A retrospective comparative analysis was made of the data of patients who underwent various green laser prostatectomy(GL-PVP), green laser vaporization of the prostate(GL-PVRP) and green laser enucleation of the prostate(GEL-EP) in our hospital during May 2016 and May 2018. The short-term clinical indexes such as operation time, bleeding volume, bladder irrigation time and indwelling time of urethral catheter after prostatectomy were compared and analyzed.The long-term clinical data, such as urodynamic data, postoperative IPSS score, postoperative QOL score, international erectile function index questionnaire score, postoperative complications were analyzed between groups. Results There was no statistically significant difference between preoperative general data(age, preoperative prostate volume, preoperative PSA, preoperative IPSS score, preoperative QOL score, preoperative maximum urine flow rate, preoperative residual bladder urine, international erectile function index questionnaire score) of patients in GL-PVP group, GL-PVRP group and GEL-EP group(P>0.05). Compared with the preoperative patients in postoperative maximum urinary flow rate, postoperative bladder residual urine, postoperative IPSS score, postoperative QOL scores improved were statistically significant(P<0.01). The mean operative time of PVP, PVRP and EP in BPH treatment, .intraoperative mean blood loss, duration of continuous bladder irrigation and indwelling catheter time were statistically significant(P<0.05). However, there was no statistically significant difference in postoperative IPSS change value, postoperative QOL change value, urinary flow rate change value, and bladder residual urine change value, international erectile function index questionnaire score change value and incidence of postoperative complications. Conclusions Green laser can effectively and safely treat prostatic hyperplasia. Compared with PVRP and GL-EP, PVP has advantages of shorter operative time, less intraoperative blood loss, shorter postoperative bladder rinsing time and shorter time of indwelling urinary catheter.
