Over the past decade, a significant number of modifications have been made to the technique for prostate biopsy. In this report, we reviewed the literature regarding transrectal ultrasound-guided prostate biopsy (TRUS-BX) in terms of the various techniques of prostate biopsy, number of cores, prophylactic antibiotic selection and use, patient preparation and pain-controlling techniques applied before the procedure. The proposed advantages/ disadvantages of transitional zone and seminal vesicle biopsies were also summarized. According to the literature, TRUS-BX rather than transperineal approach should be preferred as the technique of choice in most men undergoing a prostate biopsy. The laterally directed sextant biopsy and extended biopsy approaches decrease the false-negative rate that occurs with the conventional sextant biopsy approach. As a conclusion, considering the baseline biopsy protocol, the current advice is the use of an extended biopsy scheme (12 biopsy cores without transitional zone). Laterally directed biopsies from the anterior horn should be included. Repeat as well as saturation biopsies should include the transitional zone. Local anesthesia using transrectal ultrasound-guided lidocaine injection provides adequate periprostatic nerve blockage and is recommended to reduce the pain associated with prostate biopsy. Broad-spectrum antibiotic therapy should be administered to reduce the risk of infection. |
