Abstract：Objective To discuss the clinical effectiveness of application of TRTE (Transrectal Real-time 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.
