多层螺旋CT尿路成像对肾盂和输尿管疾病的诊断价值

目的探讨多层螺旋CT尿路成像技术(MSCTU)在肾盂和输尿管疾病诊断中的应用价值。方法搜集2年间临床资料完整的肾盂和输尿管疾病患者46例,均行MSCT增强扫描,排泄期图像进行容积重建(SVR)、最大密度投影(MIP)、多平面重组(MPR)及曲面重组(CPR),获得完整的尿路影像。结果46例中,肾盂和输尿管结石16例,先天畸形12例(包括重复肾盂输尿管、腔静脉后输尿管、肾盂输尿管交处狭窄、额外肾),输尿管炎性狭窄5例,肾盂、输尿管癌7例,膀胱癌累及输尿管4例,外压性病变2例。结论MSCTU对肾盂和输尿管疾病诊断具有优势。

Clinical Evaluation of Multi-slice Spiral CT Urography in the Diagnosis of Pyelic and Uretal Disease

Objective To evaluate the diagnostic value of multi-slice spiral CT urography(MSCTU)in pyelic and uretal disease.Methods 46 cases of pyelic and ureter disease with integrated clinical data were collected in two years,all cases were undergone multi-slice spiral CT contrast-enhanced scanning,the excretory-phase images were transferred to the workstation and shaded volume rendering(SVR),maximun intensity projection(MIP),multiplanar reconstruction(MPR)and curved planar reconstruction(CPR)were performed.Results In 46 cases,16 pyelic and ureteral calculus,12 congenital deformitions(including pelviureteric duplication malformations,retrocaval ureters,ureteropelvic junction stenosis,supern-umerary kidneys),5 inflammatory stenosis,7 primary pyelic and ureteral cancer,4 ureters were involved by bladder cancer and 2 compressive lesion were found.Conclusion MSCTU has obvious advantage in the diagnosis of pyelic and uretal disease.
