Purpose:
The purpose of this study was to determine the utility of routine transperineal transition zone (TZ) biopsies.
Materials And Methods:
A total of 1028 consecutive patients underwent transrectal ultrasound-guided prostate biopsies for the first time. Sextant biopsies and additional two-core TZ biopsies were performed.
Results:
Prostate cancer detection rate was increased by sampling two additional cores from TZ.
Conclusions:
Transition zone biopsies might be reserved to improve the detection rate of prostate cancer in transperineal biopsy protocol.
