目的利用B超诊断定位上尿路结石。方法采用B超引导体外碎石治疗复杂上尿路结石78例85侧,全部病例均I期手术成功,83侧行单通道取石,2侧行双通道取石,平均手术时间60min,结石处理时间53min。结果结石粉碎率为100%,一次取净结石率85.8%,随访1～2个月,无严重手术并发症。结论B超引导体外碎石具有定位准确,具有碎石高效安全、结石清除率高、创伤小、恢复快、并发症少等特点,值得临床推广应用。
Objective To diagnose the upper urinary tract stones by B-ultrasound. Methods B-guided extracorporeal lithotripsy was performed in 78 patients with 85 cases of complicated upper urinary tract stones. All the cases were successfully performed in stage I, 83 single-access stone, 2 double-access stone, the average operation time was 60min, the stone treatment time was 53min . Results The rate of stone crushing was 100%. The rate of net stone was 85.8% at one time. The patients were followed up for 1 to 2 months without serious complications. Conclusion B-guided extracorporeal gravel has the advantages of accurate positioning, high efficiency and safety of gravel, high rate of stone removal, less trauma, faster recovery and less complications. It is worthy of clinical application.
