F14微通道在经皮肾镜取石手术中的临床应用

目的：探讨应用F14微通道行微创经皮镜取石术（MPCNL）治疗上尿路结石的疗效及安全性。方法：选取从2009年11月至2011年11月在我院进行治疗的72例结石小于2．5cm以下的上尿路结石患者，建立F14经皮肾通道进行以钬激光或气压弹道碎石取石。结果：72例患者均一次建立通道成功。术中平均出血量为20．7土5．2（5—40）mL，平均取石时间为35．3±10．8（25—60）min，一期结石清除率为95．83％，平均住院时间为9．5±2．8d。所有患者随访6—12个月未见结石复发。结论：应用F14微通道行微创经皮镜取石术（MPCNL）治疗上尿路结石创伤更小，出血更少，恢复更快等优点，是一种安全有效的手术方法，值得在临床上推广。

The Clinical Application of F14 Microchannel in Percutaneous Nephrolithotomy Stone Operation

Objective： To discuss the clinical efficacy of F14 microchannel in minimally invasive percutaneous nephrolithotomy （ MPCNL } for upper urinary tract calculi in patients. Method ：72 patients { 45males and 27 females } who had upper urinary tract calculi were selected in our hospital from November 2009 to No- vember 2011. The patients＇ stone size were less than 2.5cm. After informed consent, the patients underwent operation. Result： The mean whole operative duration was 35.3~10.8{25-60} min. The mean blood loss was 20.7＋5.2{5-40} mL. The period of stone clearance rate was 95.83%. There＇s no postoperave bleeding or fever occurred. All the 50 cases were followed up for 12 to 24 months. There＇s no calculus had recurrence. Conclusion： The F14 microchannel in minimally invasive percutaneous nephrolithotomy （ MPCNL } for upper urinary tract calculi in patients is a safe and effective surgical method.
