[Analysis of the cause of missed diagnosis in transperineal prostate biopsy with 4 cases report]

To investigate the causes of missed diagnosis in transrectal ultrasound-guided transperineal prostate biopsy.

The biopsy results of total 278 patients who received transrectal ultrasound-guided transperineal prostate biopsy from January 2012 to December 2014 in Subei People's Hospital were retrospectively analyzed, using 11 systemic divisions.

One hundred and twenty-nine patients were diagnosed with prostate cancer, and 149 patients were hyperplasia of prostate. Fifty-six patients with biopsy-negativeand obvious symptoms of lower urinary tract obstruction were underwent transurethral resection of the prostate. Four of which were found to be prostate cancer.

Early-stage prostate cancer, special prostate tumor location, inadequate biopsy tissue, special patients in limited position, and dissatisfied anesthesia may increase the risk of missed diagnosis. Targeted and individualized puncture may improve the effectiveness.
