目的:比较120 W(HPS)和80 W(KTP)绿激光前列腺汽化(PVP)术的操作技术及近期术后并发症。方法:2008年至今,我院采用PVP手术治疗BPH患者共136例,其中76例接受80 W(KTP)PVP手术治疗,60例接受120 W高性能系统(HPS)PVP手术治疗,比较两种术式的操作特点及术后6个月内的并发症。采用Wilcoxon秩和检验进行统计学分析。结果:两组患者术前平均前列腺体积相似[KTP组(50.3±18.3)g vs。HPS组(55.6±1 5.2)g,P>0.05];HPS组手术时间明显短于KTP组[KTP组(85.3±18.5)min vs。HPS组(74.2±12.6)min,P<0.05];两组激光能量消耗无明显差别[KTP组(265±53.4)kJ vs。HPS组(276±48.3)kJ,P>0.05]。术后KTP组出现延迟性血尿4例,尿路感染4例,拔管后尿潴留2例,短期急迫性尿失禁1例:HPS组出现术中包膜穿孔1例,术后延迟性出血1例。结论:120 W HPS较80 W KTP具有更高的汽化效率。两者手术操作各具特点,但120W HPS相对操作技术要求更高,并发症更少,是值得推荐的手术方式。
OBJECTIVE: To compare the operative technique and recent postoperative complications of 120 W (HPS) and 80 W (KTP) green laser prostate vaporization (PVP). METHODS: From January 2008 to present, 136 patients underwent PVP for the treatment of BPH in our hospital. Among them, 76 patients underwent 80 W (KTP) PVP and 60 patients underwent PVP by 120 W high performance system (HPS) Style of operation and postoperative complications within 6 months. The Wilcoxon rank sum test was used for statistical analysis. Results: The average preoperative prostate volume was similar in both groups [KTP (50.3 ± 18.3) g vs. HPS group (55.6 ± 1 5.2) g, P> 0.05]. The operation time of HPS group was significantly shorter than that of KTP group [KTP group (85.3 ± 18.5) min vs. HPS group (74.2 ± 12.6) min, P <0.05]. There was no significant difference in laser energy consumption between the two groups [KTP (265 ± 53.4) kJ vs. HPS group (276 ± 48.3) kJ, P> 0.05]. There were 4 cases of delayed hematuria, 4 cases of urinary tract infection, 2 cases of urinary retention after extubation and 1 case of short-term urge incontinence in the KTP group: 1 case of perforation occurred in the HPS group, 1 case of postoperative delayed bleeding example. Conclusion: 120 W HPS has higher vaporization efficiency than 80 W KTP. Both surgical operations have their own characteristics, but the 120W HPS relatively higher technical requirements, fewer complications, is the recommended surgical approach.
