摘　　要：目的探讨多层螺旋CT尿路成像与CT血管造影(MSCTU+CTA)在泌尿系恶性肿瘤诊断中的应用价值。方法选取2014年1月~2019年9月在我院同时接受MSCTU+CTA和B超(US)检查的55例泌尿系恶性肿瘤患者为研究对象,回顾性分析其影像学表现,以手术病理结果为标准评价两组检查的诊断效能。结果55例泌尿系恶性肿瘤患者中,肾癌18例,肾盂癌3例,输尿管癌2例,膀胱癌32例。US检查正确诊断42例,误诊8例,漏诊5例,定位诊断准确率为90.90%(50/55),定性诊断准确率为76.36%(42/55);MSCTU+CTA正确诊断50例,误诊3例,漏诊2例,定位诊断准确率为96.36%(53/55),定性诊断准确率为90.90%(50/55)。MSCTU+CTA的定性诊断准确率明显高于US,差异有统计学意义(P<0.05)。结论MSCTU+CTA和US是泌尿系恶性肿瘤的重要检查手段,MSCTU+CTA在定性诊断准确率方面优于US,具有重要临床应用价值。Objective To investigate the aoolication value of multi-slice spiral computed tomography urography and computed tomography angiography(MSCTU+CTA)in the diagnosis of urological malignant tumor.Methods A total of 55 participants with urological malignant tumor who were examined by MSCTU+CTA and ultrasound(US)in our hospital from January 2014 to September 2019 were selected as the study objects.Imaging was analyzed retrospectively,and the diagnostic efficacy of the two groups was evaluated according to the surgical and pathological results.Results Within the 55 malignant tumor,there were 18 cases with renal cell carcinomas,3 cases with renal pelvic cancer,2 cases with ureteral cancer,and 32 cases with bladder cancer.A total of 42 cases were diagnosed correctly,8 cases were misdiagnosed,and 5 cases were missed by US,the accuracy of location diagnosis was 90.90%(50/55),and that of qualitative diagnosis was 76.36%(42/55).As for MSCTU+CTA,there were 50 cases diagnosed correctly,3 cases were misdiagnosed and 2 cases were missed,the accuracy of location diagnosis was 96.36%(53/55),and that of qualitative diagnosis was 90.90%(50/55).The diagnostic accuracy of MSCTA+CTU was significantly higher than US,and the difference was statistically significant(P<0.05).Conclusion Both MSCTU+CTA and US play important role in the diagnosis of urological malignant tumor.MSCTU+CTA is better than US in diagnostic accuracy and has significant value for clinical application.
