Abstract

PURPOSE: We investigated whether interoperator differences exist in the setting of prostate cancer detection by transrectal ultrasound guided prostate biopsy. Our secondary aim was to investigate whether a learning curve exists for prostate cancer detection. MATERIALS AND METHODS: A prospective database from 2000 to 2008 including 9,072 transrectal ultrasound guided prostate biopsies at our institution was limited to 4,724 done at initial presentation. Biopsies were performed by 4 uroradiologists. The OR for detecting cancer on transrectal ultrasound guided prostate biopsy was calculated for likely independent prognostic variables, including operator. We also examined the rate of biopsy posi..
