【摘要】目的探讨多层螺旋CT尿路成像(MSCTU)在诊断泌尿系统先天异常方面的特点、成像方法及其临床应用价值,并将其与IVU、MRU进行比较。方法搜集4年间临床资料完整的泌尿系先天异常患者83例,对其影像资料进行对比分析。结果 83例患者中,52例行IVU检查,40例行MSCTU检查,47例行MRU检查。IVU、MSCTU、%,%,72%,%,100%,90%。%,100%,%,%,100%,%。对伴中度上尿路梗阻病变的定性诊断正确率分别为75%,100%,75%,%,100%,%。对伴重度上尿路梗阻病变的定性诊断正确率分别为32%,%,%,定位诊断正确率分别为40%,100%,100%。结论 MSCTU对显示泌尿系先天异常的整体解剖形态和细微病理变化能力强,能明显提高诊断率,可作为首选检查方法。MRU是一种安全可靠的、无创伤性的检查方法,不用对比剂,可显示尿路扩张情况、梗阻部位、梗阻端形态,尤其对碘过敏或IVU不显影、中重度肾积水的病人更为适用。

[Abstract] Objective To evaluate the imaging methods,characteristics,diagnostic value of multi-slice CT urography(MSCTU) in congenital abnormities of urinary system,and pare it with intravenous urography (IVU) and MR urography (MRU). Methods To collect 83 urinary congenital abnormities cases in four years, the data were analyzed. Several techniques, including multiplanar reformation (MPR), curved planar reformation (CPR), volume rendering (VR), maximum intensity projection (MIP) and virtual endoscopy(VE) were post-processed by mercial software (ADW ). Results A total of 83 patients with urinary congenital abnormities received IVU(n=52),MSCTU(n=40) and MRU(n=47). By IVU, MSCTU,
