Abstract 

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.
