目的探讨介入性超声在经皮肾镜取石术中的临床应用。方法67例上尿路结石患者在超声引导下经皮肾穿刺造瘘,经瘘道于输尿管镜下行Ⅰ期气压弹道碎石取石术。结果彩超引导下,取横切面短通道于合适的穿刺点穿刺造瘘,67例患者均一次造瘘成功,经单一通道行PCNL,一期或二期取尽结石,结石总清除率95.52%,手术平均时间120m in,未出现大出血等并发症。手术时效较以前有所提高。结论介入性超声对经皮肾镜治疗上尿路结石有重要的临床应用价值。
Objective To investigate the clinical application of interventional ultrasound in percutaneous nephrolithotomy. Methods 67 cases of upper urinary tract stones under the guidance of ultrasound-guided percutaneous nephrostomy fistula in the ureteroscopic stage Ⅰ pneumatic lithotripsy. Results Under the guidance of color Doppler ultrasound, a short channel of transverse cross-section was used to puncture the fistula at the appropriate puncture point. All of the 67 patients were successful in one fistula. PCNL was performed through a single channel. One or two stages of stone were removed. The total removal rate of stone was 95.52% The average operation time was 120m in. There were no complications such as bleeding. Surgery has improved than before. Conclusion Interventional ultrasound has important clinical value in the treatment of upper urinary calculi by percutaneous nephrolithotomy.
