Objective To compare the short-term outcomes of thulium laser enucleation of the prostate(ThuLEP)and plasmaknife enucleation of the prostate(PKEP)in the treatment of large volume(≥80 mL)benign prostatic hyperplasia(BPH),so as to provide reference for clinical practice.Methods Clinical data of 100 patients with large volume BPH admitted to the Shandong Provincial Third Hospital affiliated with Shandong University during Jun.2021 and Jun.2023 were retrospectively analyzed.Based on the surgical methods,patients were divided into the ThuLEP group(n=50)and PKEP group(n=50).The following parameters were compared between the two groups,including preoperative maximum flow rate(Qmax),international prostatic symptom score(IPSS),quality of life score(QoL),operation time,intraoperative blood loss,weight of enucleated prostate tissue,postoperative bladder irrigation time,catheterization time,hospital stay,complication rate,and postoperative Qmax,IPSS,and QoL at 3 months.Results The operation time[(79.04±9.42)min vs.(80.10±8.94)min],intraoperative blood loss[(42.86±7.84)mL vs.(43.32±7.36)mL],and postoperative continuous bladder irrigation time[(19.88±4.13)h vs.(20.10±4.04)h]were not statistically different between the ThuLEP and PKEP groups(P＞0.05).The weight of enucleated tissue during ThuLEP was higher than that during PKEP[(69.44±4.90)g vs.(65.06±5.25)g],postoperative catheterization time was shorter[(27.20±4.07)h vs.(29.02±4.86)h],and hospital stay was shorter[(3.30±0.66)d vs.(4.05±0.91)d],with statistically significant differences(P＜0.05).Three months after operation,the Qmax,IPSS,and QoL score in both groups were significantly improved(P＜0.05),but there were no statistically significant differences between the two groups(P＞0.05).There was no statistically significant difference in the complication rate between the ThuLEP and PKEP groups(2％vs.4％,P＞0.05).Conclusion Both ThuLEP and PKEP have good short-term efficacy and safety in the treatment of large volume BPH,but ThuLEP is superior to PKEP in terms of reducing enucleated prostate weight,and shortening postoperative catheterization time and hospital stay.
