目的:探讨C臂数字减影X线引导在经皮肾镜取石术(PCNL)建立经皮肾通道的应用效果。方法:在C臂数字减影X线机透视下对320例上尿路结石患者一期建立经皮肾通道。结果:320例患者穿刺成功率100%,其中双侧肾穿刺19例,单侧双通道34例。建立经皮肾通道时间10~90min,平均30min。无一例发生大出血、肾盂穿孔、脏器损伤等严重并发症。结论:C臂数字减影X线机下在PCNL中建立经皮肾通道穿刺成功率高,并发症少,具有重要的应用价值。
Objective: To evaluate the clinical effect of C-arm digital subtraction X-ray guided percutaneous nephrolithotomy (PCNL) in establishing percutaneous renal access. Methods: Percutaneous renal access was established in 320 patients with upper urinary tract stones under C-arm digital subtraction radiography. Results: The success rate of puncture in 320 patients was 100%, including 19 cases of bilateral renal puncture and 34 cases of unilateral double channel. The establishment of percutaneous renal access time 10 ~ 90min, an average of 30min. No case of major bleeding, peritoneal perforation, organ damage and other serious complications. Conclusion: C-arm digital subtraction X-ray machine in PCNL established percutaneous renal access puncture high success rate, less complications, has important application value.
