Abstract

To determine the reliability of gray scale ultrasound in detecting urinary tract obstruction, a prospective study of 67 patients examined by both excretory urography and ultrasound was undertaken. The degree of hydronephrosis was defined by urographic criteria, and the corresponding echograms were analyzed without knowledge of the urographic results. Hydronephrosis was correctly diagnosed by ultrasound in 46 of 47 kidneys shown to be obstructed on urography, for a sensitivity of 98%. Our results show that when obstruction is the sole clinical question, ultrasound is an effective screening test. Thus many patients with a variety of medical diseases of the kidney can be spared excretory urography.

摘要

为了确定灰阶超声检测尿路梗阻的可靠性,我们对67例同时接受排泄性尿路造影和超声检查的患者进行了一项前瞻性研究。根据尿路造影标准定义肾盂积水的程度,并在不知道尿路造影结果的情况下分析相应的超声图像。在47例经尿路造影显示有梗阻的肾脏中,超声正确诊断出46例肾盂积水,敏感性为98%。我们的结果表明,当梗阻是唯一的临床问题时,超声是一种有效的筛查方法。因此,许多患有各种肾脏疾病的患者可以不必接受排泄性尿路造影检查。
