Abstract:
Objective To investigate the clinical significance of contrast-enhanced transrectal ultrasound(CE-TRUS) in the perineal prostate biopsy. Methods A total of 116 patients was undergone prostate biopsy through the perineum under the direction of tansrectal ultrasound. Prostate biopsy standard was based on 2007 CUA revised guidelines for diagnosis and treatment of urological diseases.Color Doppler ultrasonography was used to check the prostate and to learn the prostate focal lesion,size, number and echo color Doppler flow characteristics. Of the 116 cases, 43 patients was undergone contrast-enhanced transrectal ultrasound. Results The biopsy results confirmed the diagnosis of prostate cancer was 64 cases, Benign prostatic hyperplasia was 52 cases. Of 43 cases who undergone contrast-enhanced transrectal ultrasound, Prostate cancer and Benign prostatic hyperplasia were 25 and 18 cases, respectively. CE-TRUS group and TRUS group showed no statistical difference between two groups. Analyzed the cases with PSA≤30 ng/ml, CE-TRUS group had a higher positive rate of biopsy (P=0.046). Conclusion TRUS guided transperineal biopsy of prostate might be an method for the diagnosis of prostate cancer with a higher accuracy rate. CE-TRUS can improve the biopsy positive rate of prostate cancer.
