目的:评价超声引导经皮肾镜双频双导管碎石术处理复杂性上尿路结石的疗效。方法:78例82侧肾结石患者均在超声引导下穿刺建立F24经皮肾通道,采用双频双导管碎石系统(cyberwand)进行碎石和清石。结果:全部患者均获得手术成功,77侧行单通道取石,5侧行双通道取石,平均手术时间(79.8±43.2)min,平均结石处理时间为(42.0±17.3)min。总体结石清除率为90.2%(74/82)。3例患者接受输血,其中2例行选择性肾动脉栓塞治疗控制出血,无严重感染患者。结论:经皮肾镜结合双频双导管碎石系统处理肾结石碎石高效安全,并发症少。
OBJECTIVE: To evaluate the efficacy of ultrasound-guided percutaneous nephrolithotracheal dual-head dual catheter lithotripsy in the treatment of complex upper urinary tract calculi. Methods: A total of 78 patients with renal pelvis and 82 patients with renal pelvis underwent F24 percutaneous renal tunneling under the guidance of ultrasound. Macadamy and boulder stone were excised by dual - frequency double catheter system. Results: All the patients were successfully operated. All patients underwent single-channel stone extraction and double-channel stone extraction on the 5 sides. The average operation time was 79.8 ± 43.2 min and the average stone treatment time was 42.0 ± 17.3 min. The overall stone clearance rate was 90.2% (74/82). Three patients underwent transfusions, two of whom underwent selective renal artery embolization to control bleeding without severe infection. Conclusion: Percutaneous nephrolithotomy combined with dual-frequency dual-catheter lithotripsy is effective and safe for the treatment of renal calculi with few complications.
