摘要目的验证经皮肾镜取石术(PCNL)后经造瘘口超声成像评估输尿管通畅性的可行性。材料与方法该前瞻性双盲实验研究符合HIPAA,经伦理委员会批准,并获得知情同意。病人在接受经皮肾镜取石术后1 d行造瘘口超声成像及造瘘口X线透视成像。超声对比剂采用Optison微泡对比剂(全氟丙烷白蛋白微球,GE医疗集团,奥斯陆,挪威),剂量1.5 m L,通过肾造瘘管注入,膀胱内出现对比剂视为输尿管通畅。分析超声成像结果与透视结果的一致性。结果对9例
Abstract Objective To verify the feasibility of percutaneous nephrolithotomy (PCNL) for the evaluation of ureteral patency by trans-stoma ultrasonic imaging. Materials and Methods This prospective, double-blind, experimental study was in accordance with HIPAA, approved by the Ethics Committee, and informed consent was obtained. Patients underwent percutaneous nephrolithotomy 1 d stoma ultrasound imaging and ostomy X-ray imaging. Ultrasound contrast agent using Optison microvesicle contrast agent (perfluoropropane albumin microspheres, GE Medical Group, Oslo, Norway), a dose of 1.5 m L, injected through the renal fistula, the presence of contrast agent in the bladder as ureteral patency. Analysis of ultrasound imaging results and the consistency of the results. Results of 9 cases
