多重影像学手段在多通道经皮肾镜治疗鹿角形结石中的应用

Effects of multiple imaging methods for patients with renaI staghorn calculi in multichannel percutaneous nephrolithotomy

目的：探讨以术前泌尿系CT三维成像、术中B超与X射线联合引导为主要特点的多重影像学手段在多通道经皮肾镜取石术（PCNL）治疗鹿角形结石中的价值,并研究其适用条件。方法：对2011年9月~2013年9月在我院进行多通道PCNL治疗的鹿角形结石患者的临床资料进行回顾性分析,根据采用的影像学方法的区别而分成不同的观察组：多重影像学组、B超X射线联合组和B超组,并且对手术时间、出血量、结石清除率等指标进行统计学分析。结果：采用多重影像学检查的患者手术时间、出血量、结石清除率等指标均优于其他各组（P〈0.05）。结论：通过多重影像学手段可以更全面地反应此类患者的病情,包括结石大小、位置、形态等,并可以提高穿刺定位的准确性,最终改善手术效果,减少并发症的发生。

Objective：To evaluate the effects of multiple imaging methods including CT 3Dimaging and guidance of B-mode ultrasound combined with X radiography in multichannel percutaneous nephrolithotomy（PCNL）for treatment of renal staghorn calculi,and study its indications.Method：We analyzed the cases with renal staghorn calculi from September,2011 to September,2013 in our hospital.All patients were treated by multichannel PCNL,and divided into three groups according to different imaging methods：multiple imaging group,B ultrasound and X radiation group,simple B ultrasound group.Operation time,blood loss,and stone clearance rate were statistically analyzed.Result：The data of multiple imaging group is superior to other groups including operation time,blood loss,and stone clearance rate（P〈0.05）.Conclusion：Through multiple imaging methods,it is capable to know more comprehensive information about patients,increase the accuracy of puncturation,improve operation effect,and reduce the incidence of complications.
