目的:探讨一步扩张法建立经皮肾通道技术在上尿路结石治疗中的应用效果,同时评估这种技术在经皮肾镜碎石取石术中的安全性和有效性。方法:我院自2013年7月~2015年3月采用一步扩张法建立经皮肾通道125例137个(A组),序贯式筋膜扩张法建立经皮肾通道112例122个(B组),比较两组患者建立通道的时间、通道扩张成功率、集合系统穿孔和肾脏出血等相关指标。结果:A组在通道建立的时间上有明显优势,时间明显缩短,通道扩张成功率明显提高;集合系统穿孔和肾脏出血等指标差异无统计学意义。结论:一步扩张法建立经皮肾通道技术安全有效,治疗效果令人满意,是一种快速、安全、有效的经皮肾通道建立技术。
Objective: To explore the application of the one-step expansion method in the treatment of upper urinary tract stones and to evaluate the safety and effectiveness of this technique in percutaneous nephrolithotripsy. Methods: From January 2013 to March 2015, 137 patients (group A) with 125 cases of percutaneous renal access were established by one-step expansion in our hospital. 122 cases of percutaneous renal access were established by sequential fascial expansion (group B) Group). The time of establishing the channel, the successful rate of channel expansion, the perforation of the collection system and the renal bleeding were compared between the two groups. Results: The time of establishing channel in group A was obviously superior, the time was shortened, and the success rate of channel expansion was obviously improved. There was no significant difference in the indexes such as perforation and renal hemorrhage in collection system. Conclusion: The one-step expansion method is a safe and effective method to establish percutaneous renal access and the treatment is satisfactory. It is a fast, safe and effective technique to establish percutaneous renal access.
