Diagnostic sonographic and radioisotope scanning techniques have been shown to be useful in the diagnosis of obstructive uropathy. The accuracy of both methods was compared and sonography was found to provide the more accurate data (sensitivity, 90%; specificity, 98%; accuracy, 97%). Sonography provides excellent anatomic information and enables one to grade the degree of dilatation. Renal radionuclide studies were less sensitive in detecting obstruction, particularly in the presence of chronic renal disease, but offered additional information regarding relative renal blood flow, total effective renal plasma flow, and interval change in renal parenchymal function.
诊断性超声和放射性核素扫描技术已被证明在梗阻性尿路病的诊断中有用。对这两种方法的准确性进行了比较，发现超声检查能提供更准确的数据（敏感性为90%；特异性为98%；准确性为97%）。超声检查提供了出色的解剖信息，并能对扩张程度进行分级。肾放射性核素研究在检测梗阻方面不太敏感，尤其是在存在慢性肾病的情况下，但能提供有关相对肾血流量、总有效肾血浆流量以及肾实质功能的间期变化的额外信息。
