Abstract

Two hundred consecutive patients were evaluated for renal obstruction using both static B-scanning and high resolution real-time scanning. The overall diagnostic accuracy was 93% for the static B-scanner and 94% for the real-time unit, with a false positive diagnostic rate of 8% for each. Because of its greater flexibility and shorter scanning time, real-time can replace static B-scanning in the diagnosis of renal obstruction. It has also become the preferred method of guidance for interventional uroradiological procedures. The pitfalls of real-time scanning in evaluating renal obstruction are also discussed.

摘要

对200例连续患者同时使用静态B超扫描和高分辨率实时扫描评估肾梗阻情况。静态B超扫描仪的总体诊断准确率为93%，实时扫描仪为94%，两者的假阳性诊断率均为8%。由于实时扫描具有更大的灵活性和更短的扫描时间，在肾梗阻诊断中可取代静态B超扫描。它也已成为介入性尿路放射学检查的首选引导方法。文中还讨论了实时扫描在评估肾梗阻时存在的缺陷。
