Purpose: The decision to repeat prostate biopsy in a patient in whom the first biopsy did not detect prostate cancer poses a challenge to urologists. Many published series show a low yield on repeat biopsy using standard techniques. We reviewed our data on the 5 region prostate biopsy method to evaluate its yield in the repeat biopsy population. Materials and Methods: A total of 125 repeat transrectal ultrasound guided prostate needle biopsy sessions were done in 110 patients for standard indications using the 5 region method. Pathological findings were reviewed and the yield of the additional regions was analyzed. Results: Patients were categorized with respect to the initial biopsy technique. In those who underwent 1 and more than 1 previous sextant biopsy the relative increase in yield of the 5 region technique over the standard sextant technique was 31% and 33%, respectively. In the cohort that underwent previous 5 region biopsy the relative increase in yield of the 5 region technique over the standard sextant technique was 38%. Conclusions: In the setting of repeat biopsy the 5 region method results in an increased yield over the sextant method. It is true in patients who have previously undergone biopsies with the sextant or 5 region technique.
