IVP联合MSCT平扫在输尿管梗阻病变中的价值

The Value of IVP Combined with MSCT in Ureteral Obstruction Disease

目的:探讨静脉尿路造影(IVP)联合多层螺旋CT(MSCT)平扫在输尿管梗阻病变中检查的价值。方法:将临床疑诊为输尿管疾病患者首先行IVP检查,从IVP检查中选出输尿管梗阻患者40例再行MSCT平扫为研究对象,将原始资料传至AW 4.2工作站,分别进行多平面重组(MPR)、曲面重组(CPR)、容积再现(VR)和最大密度投影(MIP);对比单纯IVP及IVP+MSCT诊断结果与手术结果在输尿管梗阻检查中的定位、定性准确性。结果:IVP+MSCT确诊38例,诊断率95%(38/40);单纯IVP确诊27例,诊断率67.5%(27/40),两者之间具有明显统计学意义(P<0.01)。单纯IVP与IVP+MSCT在输尿管梗阻定位诊断上具有较好的一致性。结论:IVP+MSCT平扫对输尿管梗阻的定位、定性诊断更准确,并且明显降低了辐射剂量及对比剂剂量,既省时省力,又节约检查费用。

Objective： Study on intravenous urography （IVP） combined with multi-slice spiral CT （MSCT） examination in the value of urethral obstruction check. Materials and methods： Will clinical suspected diagnosis for ureteral disease patients first line IVP check, from IVP check in the elected hreteral obstruction patients 40 cases again line MSCT fiat sweep for research object, will original information pass to AW 4.2 workstation, respectively for more plane restructuring （MPR）, and surfaces restructuring （CPR）, and volume reproduce （VR） and maximum density projection （MIP）; comparison simple IVP and the IVP ＋ MSCT diagnosis results and surgery results in ureteral obstruction check in the of positioning, and qualitative accuracy. Results： IVP ＋ MSCT diagnosed 38 cases, diagnosis rate was 95% （38/40）; simple 1VP diagnosed 27 cases, diagnosis rate was 67.5% （27/40）, with significant difference between them （P〈0.01）. Simple IVP and IVP＋ MSCT in the diagnosis of ureteral obstruction has better consistency. Conclusion： IVP ＋ MSCT scan on ureteral obstruction positioning, qualitative diagnosis more accurate and significantly reduced the radiation dose and the contrast dose, saving time and labor, and save the cost of examination
