利尿B超诊断上尿路梗阻的临床价值

Diuretic Ultrasound for the Assessment of Upper Urinary Tract Obstraction

本文根据速尿快速静滴后使肾集合系统分离度增加的原理，对８０例经静脉尿路造影证实有上尿路梗阻病人的给药前和给药后１５到１５０分钟的超声图像进行分析。以肾集合系统扩张后回缩的时间作为判断标准，确定上尿路梗阻的程度，并以静脉尿路造影作为对照组进行比较。结果表明，利尿Ｂ超是诊断上尿路梗阻病变的敏感方法，并具有无损伤，适应症宽，操作简单等特点，值得在临床进一步深入研究和推广应用。

This paper reported the sonographic features of 80 cases with upper urinary tract obstraction before andfrom 15 - 150 minutes after Furosemide injected intrenously, by which the collecting system would would become from collapsedto distended. All the 80 cases were confirmed by ureteropyerography. The duration from distention to collapse in the collectingsystem could be used as a diagnostic criterion and to assess the seventy of the upper urinary tract obstraction. The results werecompared with those of intravenous urography. The Preliminary results demonstrates that diuretic ultrasound imaging is a sensitive, noninvasive and easily applied procedure in the diagnosis of urinary tract obstraction. It is worthy of clinical use and further investigation.
