目的:探讨和比较80 W和120 W绿激光汽化治疗高危良性前列腺增生(BPH)的疗效和安全性。方法:将290例确诊为BPH的患者按就诊时间顺序分为两组,220例接受80 W绿激光治疗,70例接受120 W绿激光治疗。记录比较两组患者术前、术后相关临床指标、手术时间及激光激发时间。结果:所有患者手术均获得成功,两组患者的前列腺体积、国际前列腺症状评分(IPSS)、最大尿流率(Qmax)及残余尿(PVR),术前、术后相比有统计学差异(P<0.01),但两组间比较无明显差异(P>0.05)。两组的手术时间分别为(56.5±22.6)min和(45.1±20.4)min,激光激发时间分别为(31.2±10.3)min和(24.6±8.3)min,激光消耗能量分别为(159.8±29.0)kJ和(134.2±23.3)kJ,两组间比较均有统计学差异(P<0.01)。结论:绿激光前列腺光汽化术操作简单、疗效满意、出血少、并发症少、手术安全。新一代的高功率绿激光操作更为简单、手术时间短,是治疗高龄高危BPH患者理想的微创手术方法。
Objective: To investigate and compare the efficacy and safety of 80 W and 120 W green laser vaporization in the treatment of high-risk benign prostatic hyperplasia (BPH). METHODS: Two hundred and nine patients diagnosed with BPH were divided into two groups according to their time of visit, 220 patients received 80 W green laser and 70 patients received 120 W green laser. Record and compare the two groups of patients before and after surgery related to clinical indicators, operation time and laser excitation time. RESULTS: Surgery was successful in all patients. Prostate volume, IPSS, Qmax and residual PVR were significantly different between the two groups (P> 0.05) P <0.01), but there was no significant difference between the two groups (P> 0.05). The operative time of the two groups were (56.5 ± 22.6) min and (45.1 ± 20.4) min respectively, and the laser excitation time was (31.2 ± 10.3) min and (24.6 ± 8.3) min respectively. The laser energy consumption was (159.8 ± 29.0) kJ and (134.2 ± 23.3) kJ, respectively, with significant difference between the two groups (P <0.01). CONCLUSION: Green laser photocoagulation of prostate is easy to operate with satisfactory curative effect, less bleeding, less complications and safe operation. The new generation of high-power green laser is simpler to operate and has shorter operation time. It is an ideal minimally invasive surgical method for the treatment of elderly patients with high-risk BPH.
