Abstract:
Objective To investigate the clinical application value of transrectal real-time tissue elastography(TRTE)guided targeted puncture in the diagnosis of prostate cancer.Methods A total of 52 patients with suspected prostate cancer who were treated in the First People's Hospital of Zhengzhou from January 2020 to December 2022 were selected as the study objects.Preoperative routine transrectal ultrasound and TRTE examination were performed to evaluate the benign and malignant prostates.For the 28 patients with suspected lesions found in TRTE,TRTE-guided targeted puncture(2 needles)+ systematic puncture(8 needles)were performed,for the 24 patients with no suspicious lesions found in TRTE,routine ultrasound-guided systematic puncture(12 needles)was performed.The efficacy of TRTE in the diagnosis of prostate cancer was analyzed and the positive rate of targeted puncture and systematic puncture was compared.Results In this study,25 cases of prostate cancer and 27 cases of benign lesions were ultimately pathologically diagnosed,while a total of 28 cases of prostate cancer and 24 cases of benign lesions were diagnosed with TRTE.The positive predictive value and negative predictive value of the diagnosis were 75.0%(21/28)and 83.3%(20/24),respectively.In 28 patients with suspected lesions found by TRTE,a total of 56 needles were targeted puncture,36 needles were diagnosed with prostate cancer,positive rate was 64.29%(36/56),and a total of 224 needles were systematic puncture,89 needles were diagnosed with prostate cancer,with a positive rate of 39.73%(89/224).The positive rate of prostate cancer by targeted puncture was significantly higher than that by systematic puncture(P<0.05).Conclusion TRTE can better diagnose prostate cancer,and its guided targeted puncture has a higher positive rate in the diagnosis of prostate cancer,which can maximize the positive rate of puncture while reducing the number of puncture needles.
