多层螺旋CT泌尿系造影诊断上尿路梗阻性疾病20例分析

Application of multi-slice spiral CT urography for diagnosis of upper urinary tract obstructive disorder in 20 cases

目的探讨多层螺旋CT泌尿系造影(MSCTU)在上尿路梗阻性疾病诊断中的应用价值。方法选择2008年7月至2012年6月该院收治的上尿路梗阻性疾病20例,行多层螺旋CT扫描,将原始数据三维重建后进行尿路成像,并与X线平片、B超、静脉尿路造影检查结果进行对比分析。结果 5例于1h显影,1例延迟至2h显影,3例1侧未显影,其他11例均正常显影。结论 MSCTU是一种无创伤且安全有效的非侵袭性影像检查方法,对上尿路梗阻性疾病的诊断有重要的临床应用价值。

Objective To investigate the application value of multi-slice spiral CT urography（MSCTU） in the diagnosis of upper urinary tract obstructive disorder.Methods 20 patients with upper urinary tract obstructive disorder treated from July 2008 to June 2012 were performed MSCTU scan.The primary data were performed the three dimensional reconstructions for the comparison with the results of X-ray,B-type ultrasound and IVU.Results 5 cases were developed at 1 h,1 case was postponed to develop at 2 h,3 cases had undeveloped one side and other 11 cases were normally developed.Conclusion MSCTU has the high sensitivity and high specificity,and can clearly display the upper urinary tract lesions,congenital variations and deformities.
