Abstract：Objective:To explore the clinical value and safety of TRUS-guided transperineal biopsy with the 12+X method in the diagnosis of prostate carcinoma.Methods:A total of 1300 men underwent TRUS-guided transperi-neal biopsy with the 12+X method for suspected prostate carcinoma from Sep.2009 to May 2014.The average age was 70.5 years old.All patients received PSA level,digital rectal examination(DRE),TRUS and MRI examinations. 937 cases received 12+X-core method biopsy and 363 cases received 12-core biopsy.Their clinical data were retro-spectively analyzed.Results:The average number of biopsy core was 14.5(range 12 to 24).The average operation time was 20.4 min(15 to 30 min).Prostate carcinoma was detected in 540 (41.5%),accounting for 13.1%, 17.1%,31.9% and 73.8% in those with PSA <4.0μg/L,4-<10μg/L,10-20μg/L and >20μg/L respectively, 24.0% in those with abnormal findings DRE,30.1% in those with abnormal echoes on TRUS and 59.2% in those with abnormal echoes on MRI.Complications after prostatic biopsy included gross hematuria in 201 cases,acute uri-nary retention in 21 and fever in 5,but no other serious complications were observed.The positive rate was 47.2%in 12+X-core group and 34.5% in 12-core group.Conclusions:TRUS-gu ided transpefineal biopsy with the 12+X method,with high accuracy and fewer complications,is an ideal approach to the diagnosis of prostate carcinoma.
