目的:评估Amplatz扩张器一步到位筋膜扩张法在微通道经皮肾镜术(mPCNL)中的可行性和安全性。方法:2010年7月至2013年7月,依据采用Amplatz扩张器扩张筋膜方式的不同,将愿意接受mPCNL的患者随机分为2组,Ⅰ组101例,采用依序筋膜扩张法;Ⅱ组112例,采用一步到位筋膜扩张法。两组患者在通道成功率、通道建立时间、失血量、结石清除率和术后住院时间等方面进行比较。结果:两组患者均成功进行mPCNL,Ⅰ组患者在通道建立时间方面明显长于Ⅱ组[(5.3±1.7)min vs(2.1±1.3)min,P<0.05],两组在失血量、结石清除率和术后住院时间等方面差异无显著性(P>0.05)。结论:Amplatz扩张器一步到位筋膜扩张器扩张法节约了手术时间,在mPCNL中是安全、可行的。
PURPOSE: To assess the feasibility and safety of the Amplatz dilator in one-step fascia dilation in microchannel percutaneous nephrolithotomy (mPCNL). METHODS: From July 2010 to July 2013, patients who were willing to accept mPCNL were randomly divided into two groups according to the way of using Amplatz dilator to expand the fascia: group Ⅰ (101 cases), sequential fascia dilation method (Ⅱ) Group 112 cases, using one step fascia expansion method. Two groups of patients in the channel success rate, channel establishment time, blood loss, stone clearance rate and postoperative hospital stay were compared. Results: The mPCNL was successfully performed in both groups. The duration of channel establishment in group Ⅰ was significantly longer than that in group Ⅱ [(5.3 ± 1.7) min vs (2.1 ± 1.3) min, P <0.05]. The blood loss, There was no significant difference in rates and postoperative hospital stay (P> 0.05). Conclusion: Amplatz dilator placement of one-step fascia dilator saves time and is safe and feasible in mPCNL.
