Design: Retrospective study. Setting: National Hospital Organization Kyoto Medical Center, Kyoto, Japan. Patient(s): All 46 patients who underwent the LARS operation using the KTP laser. Intervention(s): The LARS operation using the KTP laser for treatment of deep rectal endometriosis. Main Outcome Measure(s): Operative and postoperative outcome. Result(s): Meaningful improvements in clinical symptoms were obtained with the LARS operation using the KTP laser with acceptable levels of postoperative morbidity. Bowel leakage did not occur in any of the patients. Conclusion(s): Deep rectal endometriosis can be treated effectively with the LARS operation using the KTP laser.展开更多
目的探讨经尿道大功率磷酸钛氧钾晶体(绿激光)激光术(PVP)治疗良性前列腺增生症(BPH)的有效性和安全性。方法将180例BPH患者按治疗方法的不同分为PVP组与经尿道前列腺等离子切除术(TUPKRP)组,各90例。对两组患者手术时间、术中出血量、...目的探讨经尿道大功率磷酸钛氧钾晶体(绿激光)激光术(PVP)治疗良性前列腺增生症(BPH)的有效性和安全性。方法将180例BPH患者按治疗方法的不同分为PVP组与经尿道前列腺等离子切除术(TUPKRP)组,各90例。对两组患者手术时间、术中出血量、术后冲洗时间、术后导尿管留置时间、术后并发症发生率、拔管后24h最大尿流率(Qmax),术后3个月IPSS、QOL、Qmax等进行比较。结果两组手术时间、术中出血、膀胱冲洗时间、留置导尿时间、术后刺激症发生率及手术并发症率差异均有统计学意义(均<0.05),两组拔管后24 h Qmax、术后3个月IPSS、QOL及Qmax差异均无统计学意义(均>0.05)。结论 PVP手术在实际临床应用过程中能达到与TUPKRP相同治疗效果,并比TUPKRP更少出现并发症以及更短的留置导尿管时间。展开更多
为实现1.06μm波长激光向人眼安全1.57μm激光的能量转移,同时在输出光束中保留原1.06μm波长的泵浦光,以得到双波长激光的混合输出。本文从光参量振荡器(OPO)的基本原理出发,对磷酸氧钛钾(KTP)晶体的光学参量振荡(OPO)获得重频双波长...为实现1.06μm波长激光向人眼安全1.57μm激光的能量转移,同时在输出光束中保留原1.06μm波长的泵浦光,以得到双波长激光的混合输出。本文从光参量振荡器(OPO)的基本原理出发,对磷酸氧钛钾(KTP)晶体的光学参量振荡(OPO)获得重频双波长激光输出的过程进行了理论分析和实验研究。采用内腔OPO(IOPO),工作在重频20 Hz下,获得了1.57μm和1.06μm双波长激光混合输出能量大于38 m J,其中1.57μm波长信号光20 m J,脉宽5 ns;1.06μm泵浦光18 m J,脉宽6 ns,并且波形未出现外腔OPO所观察到的中央凹陷,实验结果与理论分析相吻合。展开更多
