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±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。
Objective: To investigate the efficacy and safety of minimally invasive percutaneous vitrectomy (MPCNL) with F14 microchannel in the treatment of upper urinary calculi. Methods: From November 2009 to November 2011 in our hospital for treatment of 72 cases of stones less than 2.5cm in patients with upper urinary tract stones, the establishment of F14 percutaneous renal access to holmium laser or pneumatic lithotripsy stone. Results: All the 72 patients established the channel successfully. The mean intraoperative blood loss was 20.7 ± 5.2 (5-40) mL, the average time of stone retrieval was 35.3 ± 10.8 (25-60) min, the first stage stone clearance rate was 95.83% and the average length of hospital stay was 9.5 ± 2.8 days. All patients were followed up for 6-12 months no recurrence of stones. Conclusion: It is a safe and effective surgical method to treat upper urinary tract stones with less trauma, less bleeding and faster recovery by F14 microchamber with minimally invasive percutaneous vitrectomy (MPCNL), which is worthy of clinical promotion .
