Abstract

A total of 98 patients aged 18-67 years (mean age 42.5 +/- 10.3 years) suspected to have a pelviureteral stricture (PUS) were examined using ultrasound investigation in B-mode (BUI), excretory urography (EU), angiography, slice and multislice computed tomography (SCT, MSCT). This combined examination allowed to make diagnosis of hydronephrosis in 83 (84.7%) patients including PUS diagnosis in 48 (57.8%) patients. Basing on CT findings PUS was operated in 41 (85.4%) patients. Sensitivity, specificity and accuracy of BUI in detection of the level of the upper urinary tract obstruction was 92.8, 75.0, 89.3%, EU--94.5, 77.8, 92.2, SCT--100, 97, 98.1%, respectively. MSCT detected the level of the obstruction in all the cases. PUS was identified by BUI in 26.5, 89.3, 65.6, EU--in 81.3, 73.7, 79.1, by SCT in 90.5, 96.8, 94.2, MSCT--96.3, 100, 97.8% cases. Thus, MSCT is most effective in radiodiagnosis of PUS and can be recommended as a method of choice in PUS.

摘要

对98例年龄在18至67岁（平均年龄42.5±10.3岁）疑似患有肾盂输尿管狭窄（PUS）的患者，采用B型超声检查（BUI）、排泄性尿路造影（EU）、血管造影、单层和多层计算机断层扫描（SCT、MSCT）进行检查。这种联合检查在83例（84.7%）患者中诊断出肾积水，其中48例（57.8%）患者诊断为PUS。基于CT检查结果，41例（85.4%）患者接受了PUS手术。BUI检测上尿路梗阻水平的敏感性、特异性和准确性分别为92.8%、75.0%、89.3%；EU分别为94.5%、77.8%、92.2%；SCT分别为100%、97%、98.1%。MSCT在所有病例中均检测到梗阻水平。BUI诊断PUS的病例分别占26.5%、89.3%、65.6%；EU分别占81.3%、73.7%、79.1%；SCT分别占90.5%、96.8%、94.2%；MSCT分别占96.3%、100%、97.8%。因此，MSCT在PUS的放射诊断中最有效，可推荐作为PUS的首选检查方法。
