摘 要:目的:探讨MSCT血管成像(MSCTA)及尿路成像(MSCTU)在肾盂输尿管连接部梗阻(UPJO)诊断中的价值。方法:回顾性分析经手术病理证实的16例UPJO患者的MSCTA及MSCTU影像资料,利用多种后处理重组技术(MPR、CPR、MIP、VR)进行重组。结果:16例肾盂输尿管连接部梗阻中,梗阻位置全部诊断正确。梗阻原因诊断为输尿管息肉1例,血管压迫3例,炎性狭窄12例。术前诊断与手术探查及病理结果基本一致。结论:MSCTU和MSCTA可作为UPJO术前评估的常规方法,在诊断引起UPJO的疾病方面具有重要价值。Objective:To evaluate the role of MSCTU and MSCTA in the diagnosis of ureteropelvic junction obstruction(UPJO).Methods:MSCTU and MSCTA were performed in 16 patients with UPJO suggested by intravenous urography(IVU) or other imagings.The raw data were reconstructed into thin slice images and then were processed by using the techniques including maximum intensity projection(MIP),multiple planar reformation(MPR),and volume rendering(VR) and compared with surgical and pathological findings.Results:The obstruction locations of 16 patients(100.0%) with UPJO were confirmed by CTU and CTA.The causes of UPJO consisted of ureter polyp in 1 case,vascular compression in 3 cases and stenosis caused by chronic inflammation in 12 cases.The imaging results were well correspondent with the operative and pathological findings.Conclusion:Multi-slice spiral CT urography and angiography can be used regularly in the preoperative assessment of patients with UPJ obstruction as they can demonstrate clearly the causes of the disease.
