摘　　要：目的探讨经直肠实时组织超声弹性成像(TRTE)技术与经直肠超声(TRUS)检查在诊断前列腺癌中的应用价值。方法对51例拟诊为前列腺癌的患者于穿刺检查前行TRTE和TRUS检查,分析两种检查方法及两种方法联合诊断的结果,并与穿刺活检结果进行比较,计算其诊断效能。结果经病理检查,24例为前列腺癌,27例为前列腺良性疾病。与病理检查结果相比,TRUS诊断前列腺癌的灵敏度为79.17%,特异度为59.26%,Kappa=0.379,P<0.001;TRTE诊断前列腺癌的灵敏度为83.33%,特异度为70.37%,Kappa=0.532,P<0.001;TRUS和TRTE联合诊断前列腺癌的灵敏度为87.50%,特异度为92.60%,Kappa=0.803,P<0.001。结论 TRTE与TRUS两种检查方法联合应用可以显著提高诊断的灵敏度、特异度及与病理结果的一致性。Objective To discuss the clinical effectiveness of application of TRTE（Transrectal Realtime Tissue Elastography） and TRUS（Transrectal Ultrasonography） in diagnosis of prostatic carcinoma.Methods TRTE and TRUS were performed in 51 suspected prostatic carcinoma patients prior to puncture examinations so as to compare the two testing methods and the combination of both methods diagnosis results with the biopsy results.And the diagnostics efficiency index was also calculated.Results Of 51 patients,24 patients were diagnosed with prostate cancer and 27 patients with benign prostate disease through pathological examinations.In contrast with pathological examinations,the sensitivity and specificity of TRUS in diagnosis of prostate carcinoma were 79.17% and 59.26% respectively with Kappa=0.379（P 〈0.001） versus TRTE’s 83.33% and 70.37% respectively with Kappa=0.532（P 〈0.001）.The sensitivity and specificity of TRUS combined with TRTE in diagnosis of prostate carcinoma were 87.50% and 92.60% with Kappa=0.803（P〈0.001）.Conclusion Application of combination of TRTE and TRUS in differential diagnosis of prostate carcinoma demonstrated its remarkably-improved sensitivity,specificity and consistency with pathological findings.
