Abstract：Objective To compare the efficacy and safety of 120 W 2 μm laser vapoenucleation and transurethral plasmakinetic resection of prostate(PKRP) in the treatment of large-volume benign prostatic hyperplasia (BPH).Methods Totally 340 patients with large-volume BPH from January 2011 to January 2015 in Shanxi Provincial People's Hospital randomly had 2 μrn laser vapoenucleation (n =182,vapoenucleation group) and PKRP(n =158,PKRP group).Operation time,hemoglobin level,bladder irrigating time,catheterization time,postoperative hospital stay time and complications were recorded.International prostate symptom score (IPSS),quality of Life (QOL),post-voiding residual urine (PVR) and urinary peak flow rate (Qmax) were analyzed.Results All patients were successfully operated.The hemoglobin level at 1 h after operation in vapoenucleation group was significantly higher and bladder irrigating time,catheterization time,postoperative hospital stay time were significantly lower than those in PKRP group[(126.2 ± 2.8) g/L vs (106.3 ± 5.4) g/L,(8.3 ± 2.2) h vs (24.3±7.6)h,(1.9±0.7)dvs(3.6±2.7)d,(2.8±1.1)dvs(4.1±2.1)d](P＜0.05).Q PVR,IPSS and QOL at 6 months after operation were significantly improved compared to those before operation in both groups [vapoenucleation group:(17.8 ± 6.3) ml/s vs (6.3 ± 2.0) ml/s,(27 ± 12) ml vs (152 ± 68) ml,(5.9 ±2.1) scores vs (18.1 ± 5.8) scores,(1.8 ± 0.9) scores vs (4.5 ± 1.4) scores;PKRP group:(18.1 ± 6.5) ml/s vs (6.5 ± 1.7) ml/s,(26 ± 12)ml vs (142 ±73)ml,(6.1 ± 2.4) scores vs (18.6 ±6.3) scores,(1.7 ± 1.1)scores vs (4.4 ± 1.8)scores] (P ＜ 0.05);there were no significantly differences between groups(P ＞ 0.05).Incidences of mild hematuria,transient urinary tract irritation,urethral stricture in vapoenucleation group were significantly lowerthan those in PKRP group[31.9％ (58/182) vs 100.0％ (158/158),7.7％ (14/182) vs 15.2％(24/158),2.2％(4/182) vs 4.4％ (7/158)] (P＜0.05).Conclusion Clinical data of 120 W 2 μm laser vapoenucleation treating large-volume BPH is encouraging;the efficacy is equal to PKRP and the safety and recovery are superior to PKRP.
