Abstract
To improve detection rate of prostate cancer in prostate biopsy, it is important to select proper location and the number of biopsy cores. In many previous studies, various biopsy schemes have been suggested to increase biopsy efficacy. However, the most widely used current biopsy scheme still has some limitations, so that further studies are needed. Currently, 12-14 core extended biopsy has been proved to be more efficacious than standard 6 core biopsy as initial biopsy scheme. For more meticulous re-biopsy, clinically important locations which were not included in initial biopsy, such as anterior fibromuscular zone or transition zone, should be covered as well as enough number of biopsy cores. Image guided prostate biopsy considered to be helpful for improving diagnosis efficacy. However, it needs more clinical experience to be popular. (Korean J Urol Oncol 2014;12:95-100)
