经腹超声、CT尿路成像诊断膀胱癌与病理诊断的一致性分析

Analysis of the consistency between transabdominal ultrasound and computed tomography urography in the diagnosis of bladder cancer and pathological diagnosis

目的研究经腹超声(TAUS)、计算机体层摄影尿路造影(CTU)诊断膀胱癌与病理诊断的一致性。方法纳入2014年10月—2018年12月安徽省芜湖市第二人民医院收治的125例疑似膀胱癌患者为研究对象,均于术前接受TAUS与CTU检查,并以手术病理诊断结果为金标准,分析TAUS、CTU诊断膀胱癌与病理结果的一致性,并观察TAUS、CTU诊断膀胱尿路上皮细胞癌与病理结果的一致性。结果125例疑似膀胱癌患者中,TAUS诊断显示恶性病变115例、良性病变10例;CTU诊断显示恶性病变118例、良性病变7例。TAUS、CTU诊断膀胱癌的灵敏度分别为92.56%、96.69%,特异度分别为25.00%、75.00%,准确度分别为90.40%、96.00%,与病理诊断一致性检验的Kappa值分别为0.10、0.53。TAUS、CTU诊断膀胱尿路上皮细胞癌的灵敏度分别为89.08%、94.12%,特异度分别为66.67%、83.33%,准确度分别为88.00%、93.60%,与病理诊断一致性检验的Kappa值分别为0.30、0.53。结论TAUS与CTU在膀胱癌的诊断中具有重要的应用价值。

Objective To study the consistency between the diagnosis of bladder cancer and pathological diagnosis by by transabdominal ultrasound(TAUS)and to computed tomography urography(CTU).Methods A total of 125 patients with suspected bladder cancer admitted to Wuhu Second People’s Hospital from October 2014 to December 2018 were included as the research subjects.All patients underwent TAUS and CTU examinations before surgery,and the surgical pathological diagnosis results were used as the gold standard.The consistency of TAUS,CTU diagnosis of bladder cancer and pathological results were analyzed,and the consistency of TAUS,CTU diagnosis of bladder urothelial cell carcinoma and pathological results were observed.Results Among 125 suspected bladder cancer patients,TAUS diagnosis showed 115 malignant lesions and 10 benign lesions,CTU diagnosis showed 118 malignant lesions and 7 benign lesions.The sensitivity of TAUS and CTU in the diagnosis of bladder cancer was 92.56%and 96.69%,the specificity was 25.00%and 75.00%,the accuracy was 90.40%and 96.00%,and the Kappa values of the consistency test with pathological diagnosis were 0.10 and 0.53,respectively.The sensitivity of TAUS and CTU in the diagnosis of bladder urothelial carcinoma were 89.08%and 94.12%,the specificity was 66.67%and 83.33%,and the accuracy was 88.00%and 93.60%,and the Kappa values of the consistency test with pathological diagnosis were 0.30 and 0.53,respectively.Conclusion TAUS and CTU have important application value in bladder cancer diagnosis.
