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

ABSTRACT

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 microg/L, 4 -10 microg/L and > 10 microg/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.
