目的:评价微通道(F_(16～18))钬激光与标准通道(F_(22))气压弹道联合超声碎石治疗肾结石的疗效。方法:用临床对照研究分析2003年3月～2009年6月经微通道钬激光与标准通道气压弹道联合超声碎石治疗1120例肾、肾输尿管结石患者的临床资料,分析比较两组的疗效及并发症。结果:微通道经皮肾镜钬激光碎石取石术治疗组710例,标准通道经皮肾镜气压弹道联合超声碎石取石术治疗组410例,结石清除率分别为:94.6%与95.9%,差异无统计学意义(P>0.05),并发症发生率分别为:32%与33.2%,差异无统计学意义(P>0.05),平均碎石取石时间分别为(84±43)min与(56±21)min,差异有统计学意义(P<0.01)。结论:两种方法的结石清除率、并发症发生率无显著性差异,均是微创、高效的碎石方法。两种通道严重出血、感染发生率无显著性差异。标准通道气压弹道联合超声碎石清石效率优于微通道钬激光碎石。
Objective: To evaluate the efficacy of microchannel (F_ (16 ~ 18)) holmium laser and standard channel (F_ (22)) pneumatic ballistic combined with ultrasonic lithotripsy in the treatment of renal calculus. Methods: The clinical data of 1120 patients with renal and renal ureteral calculi treated with microchannel holmium laser and standard channel pneumatic ballistic combined with ultrasonic lithotripsy from March 2003 to June 2009 were analyzed with clinical control study. The curative effect and complications of both groups were analyzed disease. Results: A total of 710 patients undergoing percutaneous nephrolithotomy and holmium laser lithotripsy in the passway were treated by standard pneumatic percutaneous nephroscope combined with ultrasonic lithotripsy. The stone clearance rate was 94.6% and 95.9% respectively, There was no significant difference between the two groups (P> 0.05). Complication rates were 32% and 33.2% respectively, with no significant difference (P> 0.05). The mean gravel stone times were (84 ± 43) min and 56 ± 21) min, the difference was statistically significant (P <0.01). Conclusion: There is no significant difference between the two methods in stone clearance rate and complication rate, both of which are minimally invasive and efficient gravel methods. Severe bleeding in both channels, the incidence of infection was no significant difference. Standard channel pneumatic ballistic lithotripsy combined with lithotripsy is superior to the micro-channel holmium laser lithotripsy.
