TRUS-guided transperineal biopsy with 9+X method for the diagnosis of prostate carcinoma:Retrospective analysis of 420 cases

Objective:To explore the clinical value and safety of TRUS-guided transperineal biopsy with the 9+X method in the diagnosis of prostate carcinoma. Methods:A total of 420 men underwent TRUS-guided transperineal biopsy with the 9+X method for suspected prostate carcinoma. Their clinical data were retrospectively analyzed. Results:Prostate carcinoma was detected in 160 (38.1%) of the 420 cases,accounting for 7.4%,17.8% and 65.4% in those with PSA 4.0 μg/L,4-10 μg/L and 10 μg/L respectively,25.0% in those with abnormal findings on digital rectal examination (DRE),and 22.2% in those with abnormal echoes on TRUS or abdominal ultrasound examination. Complications after prostatic biopsy included gross hematuria in 79 cases (18.8%),acute urinary retention in 13 (3.1%) and fever in 9 (2.1%),but no other serious complications were observed. Conclusion:TRUS-guided transperineal biopsy with the 9+X method,with high accuracy and fewer complications,is an ideal approach to the diagnosis of prostate carcinoma.
